Municipal bond performance has gotten a boost from high demand and low supply

Investor demand for municipal bonds has been robust in 2019, despite low absolute yields. Net new cash flows into municipal bond funds totaled $62 billion as of Aug. 21, representing 33 consecutive weeks of inflows and the best start to a year since record-taking began in 1992.1

The bulk of increased demand has come on the
heels of the Tax Cuts and Jobs Act (TCJA) of 2017. Under the new law, the $10,000
cap on state and local tax deductions, the so-called “SALT cap,” has resulted
in surprisingly larger individual tax bills for people in states with high
state income taxes (especially Democratic-leaning states like California, New
York, and New Jersey). The Inspector General for Tax Administration Audit of
the TCJA estimates that around 11 million taxpayers have been affected by the
SALT cap, to the tune of about $323 billion in state and local taxes that are
no longer deductible, boosting interest in municipals’ tax-exempt status.2

These record inflows have come during a time
of low supply. In 2018, new issuance fell by nearly 25% from the previous year,
and that trend has continued in 2019.3 This combination of high demand
and low supply has driven price appreciation across the municipal market and
generated the longest streak of positive monthly performance in nearly three

The Invesco Fixed Income Municipal Bond team
expects positive market technicals to persist through the early fall. Given
increased uncertainty about the US and global macroeconomic outlook, we believe
municipals may benefit in the short term as the asset class is often viewed as
a safe haven and has historically experienced increased demand during flights
to quality.

look solid

Fundamentals have also helped support
municipal market performance. We view the credit quality of the municipal
market as stable, heavily influenced by continued economic recovery and growth
across many parts of the US. Growth of state and local property tax collections
has been healthy, up 4.6% and 1.6%, respectively, through the end of March.5
The market experienced only one default in 2018, the lowest number since 1997
and the fifth year since 1986 with one or fewer defaults.6 Moody’s
reported that credit upgrades outnumbered downgrades in the second quarter of
2019 for the eighth quarter in a row and by the largest margin since the first
quarter of 2017 (157 upgrades versus 64 downgrades); the volume of upgraded
debt also exceeded downgraded debt by a wide margin ($17.7 billion versus $5.7

Further boosting state
fundamentals was the US Supreme Court decision in June 2018 to overturn a
decades-old ban on state tax collection from online sellers. The 5-4 decision
did away with the notion that governments can only collect sales taxes on
purchases made from retailers with a physical presence in their state. Since
this change, the District of Columbia and 42 of the 45 states with a sales tax
have enacted laws or regulations requiring remote sellers to remit a sales tax.8
It was widely estimated that states were collectively missing out on anywhere
from $8.5 billion to $13.4 billion a year in potential online sales tax
revenue.9 While it is still too early to determine if these are
accurate estimates, we expect increased revenue to be net positive for state
and local governments in the coming years.

In general, we believe states are better
prepared now than they were in the past to face an economic downturn. The
median “rainy day fund” balance as a share of “general fund” spending is
projected to reach 7.5% in fiscal year 2019, which would be an all-time high
according to the National Association of State Budget Officers’ Spring 2019
Fiscal Survey of States.

appear tight

One of the results of
historic inflows into the asset class has been yield and spread compression
across the municipal yield curve. So far in 2019, municipal yields have fallen
by around 75 to 100 basis points across the curve.10 This lower
yield environment has made it more challenging to find value.

Comparing benchmark municipal
yields over the past 30 years reveals that 10-year and longer investment grade
yields are currently 6 to 32 basis points away from their absolute lows,
depending on maturity and rating category.11 The summer of 2016 was
the last time yields were around current levels. Relative to taxable debt,
however, we believe longer-dated municipals exhibit some value. High-grade
20-year municipals now yield around 110% of 10-year US Treasury benchmark

By contrast, shorter-dated
bonds remain expensive. At the five-year spot, for example, the AAA
municipal-to-Treasury yield ratio is 68%, down from 72% on average over the
past 12 months.12 Following the Federal Reserve’s recent shift to an
easier monetary policy, we believe longer-dated bonds (20 to 25 years) offer
better value for new capital investments.

While high yield municipal
spreads are tight from a historical perspective, we believe there is still room
for further compression given the strength of the technical environment. The
high yield municipal market could benefit from a boost in issuance from names
outside of the usual issuers and sectors, in our view, since a diversity of
issuers and sectors potentially promotes a more balanced market environment.

Fixed income investments
are subject to credit risk of the issuer and the effects of changing interest
rates. Interest rate risk refers to the risk that bond prices generally fall as
interest rates rise and vice versa. An issuer may be unable to meet interest
and/or principal payments, thereby causing its instruments to decrease in value
and lowering the issuer’s credit rating.

Municipal securities are
subject to the risk that legislative or economic conditions could affect an
issuer’s ability to make payments of principal and/ or interest.

Safe havens are
investments that are expected to hold or increase their value in volatile

A basis point is one
