Munis/S&L tax exempt

Highlights Chart 1Targeting 2% The Fed did its best to avoid roiling markets so close to today's election, but still managed to hint at a December rate hike. The post-meeting statement was tweaked so that now only "some further evidence" rather than "further evidence" is required in order to lift the funds rate. We remain below benchmark duration in anticipation of a December rate hike. Before the end of the year we expect our 12-month discounter to reach at least 40-50bps (meaning the market will expect a further 1-2 hikes in 2017) from its current level of 28bps, and for the 10-year Treasury yield to reach 1.95-2%. While our global PMI model pegs fair value for the 10-year Treasury yield at 2.27%, the uptrend in the 10-year yield will face severe technical resistance as it approaches 2% (Chart 1). Positioning has already moved to net short duration, signaling that the bond sell-off is becoming stretched. While a Clinton victory would all but ensure a December rate hike, a Trump victory could cause a large enough market riot that the Fed delays until 2017. This would only be a brief hiccup in the return of the 10-year yield to the 1.95-2% range, and would not signal a long-lasting trend reversal. Feature Investment Grade: Neutral Chart 2Investment Grade Market Overview Investment grade corporate bonds outperformed the duration-equivalent Treasury index by +56bps in October, but have already given back -26bps of those gains so far this month (Chart 2). The index option-adjusted spread is -2bps tighter than at the end of September and, at 136bps, it remains very close to its historical average. Corporate credit performance faces two immediate risks. The first is today's election and the second is the prospect of a Fed rate hike in December. A Clinton victory would likely prompt a knee-jerk rally in risk assets and virtually ensure a rate hike next month. In that case we would be inclined to further trim exposure to credit risk in the coming weeks as the rate hike approaches. Already, we recommend investors avoid the Baa credit tier within a neutral allocation to investment grade corporates. In a recent report we pointed out that highly-rated credit (A-rated and above) performed well in the initial stages of last year's run-up in rate hike expectations, but then started to suffer once market-implied rate hike probabilities approached 100%.1 Conversely, a Trump victory would likely prompt a flight-to-safety event in markets which, depending on its severity, could also cause the Fed to delay the next rate hike into 2017. In that event, the prospect of delayed Fed tightening would make us more likely to increase credit exposure in the near term, especially if any knee-jerk sell-off in risk assets creates better value in corporates. Table 3Corporate Sector Relative Valuation And Recommended Allocation* (Continued) Table 3BCorporate Sector Risk Vs. Reward* High-Yield: Maximum Underweight Chart 3High-Yield Market Overview High-Yield outperformed the duration-equivalent Treasury index by +92bps in October, but has already underperformed the Treasury benchmark by -108bps so far in November. The index option-adjusted spread is +25bps wider since the end of September and, at 505bps, it is 16bps below its historical average. In a Special Report2 published last week we noted that while the default rate will not re-visit its previous lows (at least until after the next recession), it should decline from 5.4% to close to 4% during the next 12 months (Chart 3). However, even a slightly brighter default outlook will not be enough for junk bonds to sustain their current pace of outperformance. A simple model of lagged junk spreads and default losses explains more than 50% of the variation in 12-month high-yield excess returns. This model suggests that even with lower default losses, excess junk returns will be +264bps during the next 12 months (panel 3). The reason is that lower default losses are more than offset by the lower starting point for spreads. Junk spreads should also come under widening pressure in the very near term, as a December Fed rate hike spurs an increase in implied volatility. Maintain a maximum underweight allocation to high-yield and await a better entry point for spreads in the New Year. MBS: Overweight Chart 4MBS Market Overview Mortgage-Backed Securities outperformed the duration-equivalent Treasury index by +2bps in October, but are underperforming the benchmark by -7bps so far in November. Year-to-date, MBS have outperformed the duration-equivalent Treasury index by a mere +22bps. Since the end of September, the conventional 30-year MBS yield has risen +23bps, driven by a +21bps increase in the rate component. The option-adjusted spread has widened +2bps, while the compensation for prepayment risk (option cost) has remained flat. Unattractive option-adjusted spreads and the prospect of further increases in issuance make for bleak long-run return prospects in MBS. However, the likelihood that Treasury yields will continue to rise in the near-term means that MBS could outperform due to a decline in the option cost component of spreads (Chart 4). We will likely reduce exposure to MBS once a December rate hike has been fully digested by the market, and the uptrend in Treasury yields starts to taper off. The Fed's Senior Loan Officer Survey for the third quarter, released yesterday, showed that banks continue to ease standards on GSE-eligible mortgage loans, while demand for these same loans continues to increase. The combination of easing lending standards and strengthening demand means that issuance is likely to continue its march higher, as does the persistent uptrend in existing home sales (bottom panel). Government Related: Overweight Chart 5Government Related Market Overview The government-related index outperformed the duration-equivalent Treasury index by +5bps in October, but has already underperformed the Treasury benchmark by -9bps so far in November. The Foreign Agency and Local Authority sub-sectors drove October's outperformance, returning +24bps and +14bps in excess of Treasuries respectively. Domestic Agency debt outperformed the Treasury benchmark by +3bps, while Supranationals (-7bps) and Sovereigns (-10bps) both underperformed. After adjusting for differences in credit rating and duration, Foreign Agency and Local Authority bonds still appear attractive relative to investment grade U.S. corporate debt. Sovereigns, on the other hand, appear modestly expensive. We continue to recommend avoiding Sovereign issues while remaining overweight the other sub-sectors of the government related index. In a recent report,3 we observed that the performance of sovereign debt relative to equivalently-rated and duration-matched U.S. corporate credit tends to track movements in the U.S. dollar. As such, a continued bull market in the U.S. dollar will remain a significant headwind for sovereigns. At the country level, the only nations whose USD-denominated debt offers a spread advantage over Baa-rated U.S. corporate debt are Hungary, South Africa, Colombia and Uruguay. Unusually, bullet agency debt outperformed callable agency debt last month even though Treasury yields moved higher (Chart 5). Within Domestic Agency bonds, we continue to favor callable over bullet issues on the expectation that this divergence will not persist. Municipal Bonds: Overweight Chart 6Municipal Market Overview Municipal bonds underperformed the duration-equivalent Treasury index by -12bps in October, dragging year-to-date excess returns down to -152bps (before adjusting for the tax advantage). The average Municipal / Treasury (M/T) yield ratio is largely unchanged since the end of September, and remains close to its post-crisis average. In recent months, trends in M/T yield ratios have fluctuated alongside the betting market odds for today's Presidential election. A Trump victory would cause yield ratios to widen sharply, as President Trump's promised tax cuts would substantially de-value the tax advantage in municipal bonds. We expect yield ratios to tighten in the event that Clinton prevails, as any expectation of a Trump victory works its way out of the price. Due to attractive yield ratios relative to recent history, we are inclined to remain overweight municipal bonds in the near-term. However, we will likely downgrade the sector if yield ratios move back to previous lows. As we detailed in a recent Special Report,4 historical lags between the corporate and municipal credit cycles suggest that municipal bond downgrades will start to increase in the second half of next year, alongside a deterioration in state & local government balance sheets. Further, state & local government investment spending is poised to move higher next year, regardless of the election result, leading to even greater muni issuance (Chart 6). Elevated fund flows have offset the impact of strong issuance this year, the risk is that they will not keep pace going forward. Treasury Curve: Stay In Flatteners Chart 7Treasury Yield Curve Overview The Treasury curve has bear-steepened significantly since the end of September. The 2/10 Treasury slope has steepened +16bps and the 5/30 slope has steepened +14bps. As a result, our two curve flattener trades have struggled. Our 2/10 Treasury curve flattener has returned -41bps since initiation on September 6. Our 10/30 Treasury curve flattener has returned -25bps since initiation on September 20. Our other tactical trade - short December 2017 Eurodollar - has returned +16bps since initiation on July 12. All three of the above tactical trades are premised on the view that the Fed will deliver a rate hike in December, and that such a rate hike has not yet been fully discounted by the market. At present, we calculate that the market-implied probability of a December rate hike is 62%, as discounted in fed funds futures. The historical pattern suggests the yield curve should bear flatten as the rate hike probability approaches 100%. Unusually, the correlations between both the 2/10 and 10/30 Treasury slopes and the level of Treasury yields have moved into positive (bear-steepening) territory (Chart 7). This is especially unusual for the 10/30 slope, where the correlation has been firmly in negative (bear-flattening) territory since 2013. We continue to recommend holding curve flatteners, and expect both correlations to revert into negative (bear-flattening) territory in advance of a December rate hike, as they did last year. Any surge in bullish dollar sentiment between now and December would only increase the flattening pressure on the curve (bottom panel). So far bullish dollar sentiment has remained relatively flat, but we cannot discount a large increase in the run-up to the next rate hike, as occurred last year. TIPS: Overweight Chart 8TIPS Market Overview TIPS outperformed the duration-equivalent nominal Treasury index by +112bps in October. The 10-year breakeven rate has increased +8bps since the end of September, and currently sits at 1.68%. The 10-year TIPS breakeven rate has increased substantially during the past couple months, and has now converged with the fair value reading from our TIPS Financial model (Chart 8). Rising expectations of a Fed rate hike and a flatter Treasury curve will weigh on TIPS during the next month, and we would not be surprised to see breakevens temporarily cease their uptrend as attention turns to Fed hawkishness following today's election. But we also expect that TIPS breakevens will resume their uptrend heading into next year. As we flagged in a recent report,5 the sensitivity of TIPS breakevens to core inflation has increased since the financial crisis. We posit that the reason for this increased sensitivity is that the Fed's ability to control long-dated inflation expectations has been impaired by the zero-lower bound on rates. As a result, the trend in breakevens is increasingly taking its cue from the realized inflation data. Realized inflation continues to trend steadily higher (bottom two panels), and diffusion indexes suggest that further gains are ahead (panel 4). Given that breakevens remain well below pre-crisis levels, we intend to remain overweight TIPS relative to nominal Treasuries and ride out any near-term volatility related to a Fed rate hike. ABS: Maximum Overweight Chart 9ABS Market Overview Asset-Backed Securities outperformed the duration-equivalent Treasury index by +10bps in October, bringing year-to-date excess returns up to +101bps. Aaa-rated ABS outperformed the Treasury benchmark by +8bps on the month, while non-Aaa issues outperformed by +24bps. The index option-adjusted spread for Aaa-rated ABS has tightened -3bps since the end of September and, at 45bps, is considerably below its pre-crisis average (Chart 9). According to our days-to-breakeven measure, there still exists a valuation advantage in Aaa-rated auto ABS relative to Aaa-rated credit card ABS, but that advantage is rapidly evaporating (panel 3). We calculate that it will take 12 days of average spread widening for Aaa-rated auto ABS to underperform Treasuries on a 6-month horizon and 10 days of average spread widening for Aaa-rated credit card ABS to underperform. Moreover, credit card ABS exhibit superior collateral credit quality relative to autos. Credit card charge-offs remain near all-time lows, while the auto net loss rate appears to have bottomed (bottom panel). Further, the Fed's senior loan officer survey shows that auto lending standards have tightened for two consecutive quarters, while credit card lending standards were unchanged in Q3 following 25 consecutive quarters of net easing (panel 4). We recommend investors favor Aaa-rated credit cards over Aaa-rated auto loans within a maximum overweight allocation to consumer ABS. CMBS: Underweight Chart 10CMBS Market Overview Commercial Mortgage-Backed Securities outperformed the duration-equivalent Treasury index by +4bps in October, bringing year-to-date outperformance up to +194bps. The index option-adjusted spread for non-agency Aaa-rated CMBS has tightened -3bps since the end of September, and remains very close to its pre-crisis average (Chart 10). The Fed's Senior Loan Officer Survey for the third quarter, released yesterday, showed that banks continue to tighten standards on all classes of commercial real estate (CRE) loans (panel 3). The survey also shows that CRE loan demand continues to increase, though at a less rapid pace than in prior quarters. While CRE prices continue to march higher (bottom panel), tightening lending standards and a rising delinquency rate (panel 4) make us cautious on non-agency CMBS. Agency CMBS outperformed the duration-equivalent Treasury index by +4bps in October, bringing year-to-date excess returns up to +105bps. Agency CMBS still offer 56bps of option-adjusted spread. This is greater than what is offered by Aaa-rated consumer ABS (45bps) and conventional 30-year MBS (19bps) for a similar amount of spread volatility. We continue to recommend overweight positions in Agency CMBS. Treasury Valuation Chart 11Global PMI Model The current reading from our Global PMI Treasury model places fair value for the 10-year Treasury yield at 2.27% (Chart 11). This model is based on a linear regression of the 10-year Treasury yield on three factors, using a post-financial crisis time interval.6 The three factors are: Global Growth: Measured using the Global Manufacturing PMI (sourced from JP Morgan and Markit) Global Growth Divergences: Proxied by bullish sentiment toward the U.S. dollar (sourced from Marketvane.net) Economic Uncertainty: Measured using the Global Economic Policy Uncertainty Index (sourced from policyuncertainty.com) The correlation between the global PMI and the 10-year Treasury yield is strongly positive (panel 3). However, improving global growth is offset by any increase in bullish sentiment toward the U.S. dollar. For a given level of global growth any increase in bullish sentiment toward the dollar represents a drag on interest rate expectations. As such, bullish dollar sentiment enters our model with a negative sign (panel 4). The final component of our model - global economic policy uncertainty - captures changes in Treasury yields related to headline risk and "flights to quality". This factor enters our model with a negative sign - more uncertainty correlates with lower bond yields (bottom panel). Monetary Conditions And Rate Expectations The BCA Monetary Conditions Index (MCI) combines changes in the fed funds rate with changes in the trade-weighted dollar using a 10:1 ratio. Historically, economic downturns have been preceded by a break in this index above its equilibrium level - calculated using the Congressional Budget Office's estimate of potential GDP growth (Chart 12). Using assumptions for the time until the MCI converges with equilibrium and the annual appreciation of the trade-weighted dollar, it is possible to calculate the expected change in the fed funds rate for the cycle. The shaded region in Chart 13 shows the expected path for the federal funds rate assuming that the MCI reaches equilibrium at the end of 2019. The upper-end of the region corresponds to a scenario where the trade-weighted dollar depreciates by 2% per year and the lower-end of the region corresponds to a scenario where the dollar appreciates by 2% per year. The thick line through the middle of the region corresponds to a flat dollar. Chart 12Monetary Conditions Vs.

Special Report

Highlights Muni Credit Cycle: The reading from our Municipal Health Monitor supports low Muni/Treasury yield ratios for now, but will become less supportive near the end of 2017. This is consistent with historical lags between the muni and corporate credit cycles. Issuance: State & local government investment spending will increase in 2017, as will muni issuance for new capital. Pensions: The pension funding problem will only get worse in the coming years. Credit ratings do not adequately reflect the risk from under-funded pensions. Election: Muni/Treasury yield ratios have not yet discounted Donald Trump's recent plunge in the polls. Maintain an overweight allocation to municipal bonds for the time being, but stand prepared to gradually reduce exposure as the muni credit cycle starts to turn in late 2017. Feature The financial crisis marked a major inflection point in the municipal bond market. Not only did the economic fall-out from the housing crash lead to historically large state & local government budget gaps, but the end of bond insurance and a growing realization that municipal default is possible have focused investor attention on credit quality more than ever before. In this Special Report we zero-in on the Municipal/Treasury (M/T) yield ratio.1 We identify its major short-run and long-run drivers, and assess where it is headed in the context of the municipal bond credit cycle. The Longer-Run Outlook For Yield Ratios An important input to our understanding of the municipal credit cycle is our Muni Health Monitor (MHM). The MHM is a composite of eight indicators of state & local government budget health. Full details of the indicator and its components can be found in the Appendix to this report. The MHM has an excellent track record of signaling the major inflection points in muni ratings migration (Chart 1). We observe that the MHM bottomed in 2006, one year before the previous trough in ratings migration. The MHM also crossed into "deteriorating health" territory six months before municipal downgrades started to outpace upgrades in 2008. More recently, the MHM crossed back into "improving health" territory in Q4 2012. Muni ratings migration also peaked in Q4 2012 and upgrades began outpacing downgrades in Q4 2014. Chart 1The Municipal Health Monitor Leads Ratings We pay attention to the trends in muni ratings because ratings and state & local government net borrowing explain more than 50% of the variation in the average M/T yield ratio since 1997 (Chart 2). Further, increased investor focus on the creditworthiness of municipal issues has made the yield ratio even more responsive to ratings and net borrowing since the Great Recession. So where are we currently situated in the muni credit cycle? The MHM remains in "improving health" territory, but appears to have entered an extended bottoming-out phase. Given the re-leveraging that has already occurred in the corporate sector, it would be extremely unusual for the MHM to improve further during this cycle. In fact, our Corporate Health Monitor tends to lead the MHM by about two years (Chart 3). This squares with what we know about the behavior of state & local governments throughout the economic cycle. Chart 2The Muni Credit Cycle Illustrated I Chart 3The Muni Credit Cycle Illustrated II Typically, the corporate sector will increase debt loads when times are good and will then be forced to de-lever when the economy enters recession, profits contract and those debt loads become unsustainable. State & local government budget gaps, on the other hand, will tend to narrow during an economic recovery as rapid income growth translates into increased tax revenue. It is only during a recession that state & local government budget gaps widen, since tax revenue plummets while expenditure growth - particularly for social benefits - remains firm. The end result is that the municipal credit cycle tends to lag the corporate credit cycle. This is also apparent in the ratings data (Chart 3, bottom panel), which suggest that we should expect to see muni downgrades (and hence yield ratios) head higher near the end of next year. The typical lag between the corporate credit cycle and the municipal credit cycle suggests that M/T yield ratios should remain well behaved until late-2017, and then begin to move higher. However, the extraordinary length of the current economic recovery gives us some cause to believe that the lags in this cycle may be somewhat longer. We turn to a macro analysis of net state & local government borrowing to shed some further light on this issue. Net borrowing is simply the difference between revenues and expenditures. On the revenue side of the ledger, state & local governments have already seen a significant deceleration in tax receipts during the past year (Chart 4). Every source of tax revenue - except for property taxes - has slowed alongside what has been disappointing overall economic growth so far in 2016. While a return to the 10% revenue growth that was seen in the mid-2000s is unlikely, we expect most of the recent deceleration will soon be reversed. Aggregate weekly hours bounced sharply in September (Chart 5), and federal income tax withholdings also continue to grow rapidly. Both indicators suggest that income growth will be stronger during the next few months, which will support state & local tax receipts. On the expenditures side, while spending on social benefit programs has increased, state & local governments have largely dealt with budget gaps by cutting back severely on discretionary spending (Chart 6). Investment spending has also collapsed and, as a result, gross municipal bond issuance has been dominated by refinancing (Chart 6, bottom two panels). Chart 4S&L Government Revenue Chart 5Income Growth Will Rebound Chart 6S&L Government Expenditures This could all be about to change. Both U.S. Presidential candidates have prioritized infrastructure spending as part of their platforms. Hillary Clinton plans to increase infrastructure spending by $500 billion. This consists of $250 billion of federal infrastructure spending over the next five years and $25 billion of seed money to create a national infrastructure bank. The bank would also accept an additional $225 billion in direct loans. Clinton's plan would also bring back the Build America Bonds (BABs) program. Donald Trump has also expressed a desire to invest heavily in infrastructure, and has floated figures in the range of $1 trillion, although he has been less specific about the details. Historically, about 70% of public investment has occurred at the state & local government level (Chart 7). This suggests that if infrastructure spending became a priority it would lead to a large increase in state & local government investment and hence municipal bond issuance. However, with Clinton's plan it is still unclear whether the bulk of infrastructure spending would be financed through the Treasury market or the muni market. Certainly, to the extent that increased spending is financed through the BABs program, then tax-exempt muni issuance would not be impacted. In our view, state & local government investment spending will head higher in 2017 even without any support from the new President. The need for state & local governments to invest in infrastructure has been evident for some time, but only recently have budgets become healthy enough for governments to consider it. There is a strong correlation between state & local government investment spending and the net percentage of states with a total balance (general fund plus rainy day fund) that exceeds 5% of expenditures (Chart 8). This figure has just recently moved into positive territory and, not coincidentally, more than $200 billion worth of infrastructure spending will be on ballots requesting voter approval in November.2 Chart 7State & Local Government ##br##Drives Investment Chart 8Healthy Enough##br## To Invest The combination of resilient, but not surging, revenue growth and increased investment spending in 2017 is consistent with the idea that the muni credit cycle will follow the lead of the corporate cycle and start to turn near the end of next year. Bottom Line: The reading from our Municipal Health Monitor supports low Muni/Treasury yield ratios for now, but will become less supportive near the end of 2017. This is consistent with historical lags between the muni and corporate credit cycles. The Pension Problem Of course, the elephant in the room with regards to the long-run outlook for municipal credit quality is pensions. So far pensions have only entered our discussion of the muni credit cycle tangentially, since the pension funded ratio is a component of the MHM (see Appendix). However, large unfunded pension liabilities - should they persist - have the potential to be severely destabilizing for the muni market at some point in the future. According to the U.S. National Accounts, aggregate defined benefit pension entitlements at the state & local government level total $5.6 trillion, only 65% of which are currently funded by assets. However, this aggregate figure masks large divergences between a few municipalities with unsustainable pension liabilities and the majority of municipalities where pension liabilities are probably manageable. Chart 9Low Returns Put Pressure On Pensions In a recent report,3 the Center for Retirement Research at Boston College found that 36 states should be able to fund their existing liabilities by making annual payments that total less than 15% of revenue. However, five states - Illinois, New Jersey, Connecticut, Hawaii and Kentucky - require annual payments in excess of 25% of revenue. The breakdown is found to be similar at the city level, where pension costs were found to be manageable for the majority of cities, although Chicago, Detroit, San Jose, Miami, Houston, Baltimore, Wichita and Portland all face annual pension costs that exceed 40% of revenue. Unfortunately, while the pension situations of most municipalities are currently manageable, they are only likely to get worse. Changes in the aggregate pension funded ratio closely track returns from a portfolio that is 50% invested in the S&P 500 and 50% invested in the Barclays Treasury index (Chart 9). Based on current equity valuations, it is probably only reasonable to expect 6% annual nominal returns from the equity market during the next 10 years,4 and the 10-year Treasury yield suggests that 1.8% is a reasonable expectation for annual nominal Treasury returns. Taken together, annual nominal investment returns from a 50/50 portfolio during the next decade could be close to 4%, far below the historical average of 8.9% and also below the 7.6% average return assumed by state & local pension plans in 2014. The two main points are that: The pension problem is likely to get worse, not better Given that large under-funded pensions are concentrated in only a few states, inter-state muni allocations are very important On this second point, we observe that states with lower pension funded ratios have higher General Obligation (GO) bond yields (Chart 10), and also that not all of the difference is reflected in credit ratings. We ran a cross-sectional regression of GO bond yields against credit rating and found that a correlation remains between the residual from that regression and the pension funded ratio (Chart 11). In other words, credit rating does not adequately control for the risk presented by under-funded pensions. Chart 10Municipal Bond Yields Vs. Pension Funded Ratios Chart 11Municipal Bond Yields Vs. Pension Funded Ratios: Controlling For Credit Rating Bottom Line: The pension funding problem will only get worse in the coming years. Credit ratings do not adequately reflect the risk from under-funded pensions. The Short-Run Outlook For Yield Ratios So far we have discussed the muni credit cycle and noted that M/T yield ratios should begin to move higher on a sustained basis at some point near the end of 2017. However, the near-term drivers of M/T yield ratios suggest that an overweight allocation to municipal bonds remains appropriate for the time being. We have found that the bulk of near-term volatility in M/T ratios can be explained by four factors (Chart 12): The Global Policy Uncertainty Index5 Gross municipal bond issuance Net municipal mutual fund flows Ratings migration The Brexit shock to policy uncertainty has now mostly been reversed. Meanwhile, our Muni Excess Supply Indicator (Chart 12, panel 4) shows that gross issuance has been outpacing fund inflows of late. This should put upward pressure on yield ratios, although this pressure has been largely offset by still supportive ratings migration (Chart 12, bottom panel). Considering all factors, this short-term model shows that the average M/T yield ratio is close to fair value. A reading close to fair value is consistent with muni returns that should exceed those from duration-equivalent Treasuries most of the time (Table 1), even before adjusting for the muni tax advantage. In fact, Table 1 shows that the odds of muni underperformance only really increase once the M/T ratio appears more than one half standard deviation expensive on our model. Chart 12A Short-Term Muni Model Table 1Municipal Bond Excess Returns* Based On Fair Value Model** Residual: 2010 - 2016 The other near-term factor that supports a continued overweight allocation to municipal debt is the prospect of a Clinton victory in next month's election. Since the beginning of the year, the average M/T ratio has closely tracked the probability of a Trump election victory (Chart 13). The reasoning is entirely logical. Trump has promised large tax cuts for the highest earners. Such tax cuts would significantly de-value the tax advantage of municipal bonds and pressure yield ratios higher. In contrast, Clinton promises to raise taxes on high income individuals. This would make the tax advantage of municipal debt more valuable, and pressure yield ratios lower. Chart 13Trump Is Bad For Yield Ratios The average M/T yield ratio has not yet discounted Trump's recent plunge in the polls. This argues for the maintenance of an overweight allocation to municipal debt in the near term. Bottom Line: M/T yield ratios appear fairly valued in the near-term, and have not yet discounted Donald Trump's recent plunge in the polls. Maintain an overweight allocation to municipal bonds for the time being, but stand prepared to gradually reduce exposure as the muni credit cycle starts to turn in late 2017. Ryan Swift, Vice President U.S. Bond Strategy rswift@bcaresearch.com Alex Wang, Research Analyst alexw@bcaresearch.com Appendix: The BCA Municipal Health Monitor The BCA Municipal Health Monitor is an equal-weighted composite of eight indicators meant to quantify trends in state & local government budget gaps and debt service capability. The components consist entirely of data that are publicly available from the Bureau of Economic Analysis, Federal Reserve, Bureau of Labor Statistics and the National Association of State Budget Officers. The eight components are described below, and shown graphically in Charts A1 & A2. Chart A1Muni Health Monitor Components I Chart A2Muni Health Monitor Components II Leverage: The ratio of total state & local government liabilities (excluding unfunded pension liabilities) to total financial assets. Interest Coverage: State & local government current budget surplus (excluding interest expenditures) divided by interest expenditures. The current surplus is calculated as the difference between current revenues and current expenditures (i.e. investment spending is excluded). Pension Funded Ratio: Total assets of state & local government pension funds divided by total pension liabilities. Revenue: State & local government current revenue in nominal terms, as a deviation from its 18-quarter trend. Surplus Margin: State & local government current budget surplus as a % of current revenue. Liquidity: State & local government total financial assets less short-term liabilities, as a % of total financial assets. Employment Growth: Year-over-year % change in state and local government employment. Total Balance: Aggregate state government total year-end balance. The total balance is the general fund balance plus the rainy day fund, as a % of total expenditures. 1 The average M/T yield ratio shown in this report is calculated by taking an equal-weighted average of M/T yield ratios for 2-year, 5-year, 10-year and 30-year maturities. For each maturity point the yield ratio is calculated as the ratio between the Bloomberg Fair Value Aaa Municipal bond yield and the Federal Reserve's constant maturity Treasury yield. 2 http://www.bloomberg.com/news/articles/2016-09-13/mega-deals-lead-ballo… 3 http://crr.bc.edu/briefs/will-pensions-and-opebs-break-state-and-local-… 4 Please see Global Investment Strategy Special Report, "Global Equity Valuations: Risks And Opportunities", dated July 1, 2016, available at gis.bcaresearch.com 5 The index was created by Professors Scott Baker, Nick Bloom and Steven Davis and is driven by the number of times terms related to economic and policy uncertainty are found in newspaper articles.

There are two key risks that could derail a bear-flattening of the yield curve. The first is a Trump election victory, the second is a flaring of stress in the non-U.S. banking sector.

It's hard to make a case for attractive returns from any asset class over the next year. We dial down risk a bit but ending our overweight on junk bonds. Investors should pick up yield where they can but without taking excessive risk.

With recent comments strongly hinting that the Fed is on track for a rate hike in December, the dy-namics of the Fed Policy Loop make spread product appear extremely vulnerable.

Eventually the easing of financial conditions will strengthen the Fed's resolve to lift rates. Rate hike probabilities will rise and risk assets will struggle to cope with higher Treasury yields.

A spike in economic uncertainty explains the recent move lower in Treasury yields. Given the resilience of global growth, we expect yields to rise as uncertainty ebbs in the coming months.

Some near-term upside in Treasury yields is very likely as flight to safety flows begin to unwind. However, given that global growth divergences remain in place, we will continue to look for an opportunity to increase duration on any meaningful back-up in yields.

Assuming last month's weak employment report is not the start of a trend, the market is still discounting too low a probability that the Fed will lift rates this year. This means the Treasury curve should bear-flatten in the coming months, providing an opportunity to move to above-benchmark duration.

Financial conditions will continue to ease during the next few months, and the Fed will use its June statement to prepare the markets for a rate hike in September.
