Market Review

Concerns arose about the U.S. Financial sector, following government take-over of two regional banks. The events sparked a flight to quality that benefited highly-rated corporate and municipal bonds. Treasury yields fell sharply, per Bloomberg (See Figure 1). The curve was less inverted by month end.

The Federal Reserve (Fed), demonstrating continued resolve to slow inflation, increased the fed funds interest rate by 25 basis points (bps) to a target range of 4.75 percent to 5.00 percent at its March 21 and 22 meeting. Fed fund futures indicated a terminal fed funds rate of 5.1 percent by year-end, down from 5.4 percent at the end of February.

As the market priced in rate cuts by the summer, a disconnect reemerged between market yields and the Fed dot plot, based on media reports of market sentiment and Fed meeting minutes.

The Fed also cut its expectations for real gross domestic product (GDP) growth to 0.4 percent for the year. In addition, in a reversal of its COVID pandemic-related quantitative easing program, the Fed continues quantitative tightening efforts, allowing Treasury bonds and MBS to mature without replacing them.

Banking sector concerns emerged in early March. Asset sales by some banks to meet accelerating depositor withdrawals severely weakened their liquidity positions. In response, regulators assumed responsibility for operating Silicon Valley Bank and Signature Bank of New York.

Fed Chairman Powell said that events in the Banking sector, “are likely to result in tighter credit conditions for households and businesses, which would in turn affect economic outcomes.” If realized, the credit tightening likely would contribute to the Fed’s efforts to cool economic growth and inflation. Chairman Powell said it was “too soon to tell” how monetary policy might be managed in light of the potential conditions.

Volatility in March increased, as measured by the ICE/Bank of America Merrill Lynch MOVE Index,1 which measures bond market volatility expectations (See Figure 2). After spiking to over at 5.07 percent on March 8, the 2-year Treasury yield ended March near 4.03 percent. The 10-year closed the month at 3.47 percent.

The Bloomberg U.S. Treasury Bond Index2 gained nearly 2.9 percent for March and 3 percent for the first quarter. The Bloomberg U.S. Aggregate Bond Index3 was 2.5 percent higher for March and nearly 3 percent in the quarter. The S&P 500 Index4 added 3.5 percent in March and 7 percent for the quarter ended March 31.

Our base case continues to call for a no growth to mild recession scenario for the rest of 2023 and early 2024. Increased bank regulation, pressure on interest margins, and deposit outflows from regional banks are a negative for bank credit fundamentals and will accelerate implementation of tighter lending standards that may contribute to a slowdown of economic growth.

Municipal Market Review

Municipal bond yields tracked Treasuries and fell over the month (See Figure 3). Two-year yields fell 57bps, five-years by 42bps, 10-years by 32bps, and 30-years by 26bps.

The historically uncharacteristic curve inversion from two to 10 years (2s/10s curve) persisted, although it decreased to 11bps.

Muni/Treasury (M/T) Ratios improved from mid-February levels, closing the month at 58, 61,64, and 89 for 2, 5, 10, and 30 years, respectively (See Figure 4).

Municipal bond returns, as measured by the Bloomberg Municipal Bond Index, were the highest in 15 years for the month of March, which is a month typically associated with lower performance amid outflows to cover tax payments. The positive return completes a volatile quarter for month-to-month total returns (See Figure 5). In our view, perhaps the wide-ranging returns reflected shifting investor sentiment, with economic data wavering between appearances that inflation was declining and, then, that it was persistent. 

The Bloomberg Managed Money Short/Intermediate (1-10) Index5 gained 2.2 percent and the Bloomberg 1-10 Year Municipal Bond Blended Index6 added 1.8 percent. Longer-maturity bonds outperformed shorter-maturity issues. Lower-rated bonds outperformed higher quality.

March returns were supported by the ongoing low issuance trend, a characteristic of the municipal market during the last 24 months. Borrowing costs in the higher interest rate environment are contributing, as are broadly healthy financial positions among many municipal issuers, in our view.

The Bond Buyer reported that municipal bond issuance in March was $31.8 billion, down 30 percent year-over-year (Y/Y) but higher month-over-month (M/M). Tax-exempt municipal bond issuance was about 25 percent lower Y/Y, while taxable municipal bond issuance was down approximately 31 percent for the same period, after having been 54 percent lower Y/Y during February. Lipper data showed municipal bond mutual fund outflows of nearly $1.4 billion in March.

Corporate Market Review

Investment grade (IG) corporate bond spreads were 14bps wider, per Bloomberg data, ending March at 138bps. For March, the Bloomberg U.S. Corporate Investment Grade (IG) Index7 gained almost 2.8 percent on a total return basis, with a negative excess return of 42bps compared with duration-matched Treasuries. 

At 138bps, the IG Corporate Index option-adjusted spread continues to suggest the pricing in of a soft landing for the U.S. economy rather than an economic recession, in our view based on historical spread data. March spread widening primarily reflected volatility associated with news from Banking, the largest sector in the IG corporate markets. 

In our view, until the Government and financial regulators restore full confidence in the U.S. Banking system, Bank issuers will be focused primarily on their own balance sheets, shoring up liquidity, and considering capital raises as conditions settle. As lending standards tighten further, controllable lending activity from the Banking sector likely will slow materially, impacting credit creation and economic growth.

Per Bloomberg, the best-performing corporate sectors for the month ended March 31, 2023, were Restaurants, Wirelines, Food & Beverage, Pharmaceuticals, and Aerospace/Defense. The worst-performing were Life Insurance, Real Estate Investment Trusts, Brokerage & Asset Managers, Gaming, and Airlines.

Based on Bloomberg data, corporate bonds with longer maturities delivered the best total and excess returns. The highest rated bonds fared the best across the IG quality spectrum.

IG corporate supply for March was $100 billion, per Bloomberg data. IG fund flows in March were about $3 billion, well off the strong pace of the prior two months, per Emerging Portfolio Fund Research. 

Securitized Market Review

In March, securitized markets delivered positive total returns and negative excess returns. 

The Bloomberg MBS Index8 had a positive total return of 1.95 percent and a negative excess return of 1.11 percent. The most favorable total returns were among the 3 to 4.5 percent coupon conventional9 and Ginnie Mae10 securities. Excess returns were least negative among 5 and 5.5 percent coupon conventional issues and 4 and 5 percent coupon Ginnie Mae securities.

Bloomberg data showed Agency Commercial MBS (CMBS) earned a positive total return of 2.10 percent in March and a negative excess return of 91bps. CMBS had a positive total return of 1.09 percent and a negative excess return of 1.70 percent. Non-Agency CMBS total return was positive 20bps and excess return was negative 2.38 percent.

Within the ABS sector, securities backed by auto loans and credit cards earned positive total returns of 1.01 and 1.41, respectively, while excess returns were negative 54bps and 46bps, respectively, per Bloomberg.
