War-driven oil price shocks overwhelming pre-conflict economic data, surging IG issuance, and a triple whammy of headwinds for municipal bonds headline this week’s fixed income commentary for the week of March 12, 2026.
Economic Commentary
- January retail sales decreased -0.2%; control group sales grew +0.3%.
- ADP reported businesses added an average of just 15.5k workers in the four weeks ending February 21.
- The NFIB Small Business Optimism index dipped from 99.3 to 98.8, reflecting a modest downtick in economic expectations.
- Payrolls fell 92k in February and the unemployment rate rose from 4.32% to 4.44%. The prior two months were revised lower by a combined 69k. The twelve-month average payrolls growth is now just 13k. Dallas Fed research estimates net unauthorized migration went negative last year, accounting for only 26k fewer jobs per month — implying labor demand has fallen far faster than labor supply.
- The Atlanta Fed GDPNow forecast for Q1 GDP is 2.743%, with a +0.67% contribution from inventory changes.
- February CPI rose 0.267% headline and 0.216% core, effectively matching consensus. Year-on-year, headline ticked up from 2.39% to 2.43% while core slipped from 2.51% to 2.47%. Food inflation accelerated to +0.39% (from +0.18% in January); energy reversed from -1.46% to +0.63%. Shelter inflation was modest again at +0.2%.
Our Take
Fundamental economic data — CPI, PPI, payrolls and others — is being rendered almost irrelevant, as it predates the Middle East war and is being overwhelmed by rising oil prices and their impact on interest rates and inflation expectations. The sharp rise in both oil and rates has weighed on risk assets, but if expectations for the duration of the war shift from four to six weeks to something longer and more enduring, the effect would be considerably more pronounced. Rates were further pressured this week by massive IG issuance and Treasury auctions of 10s and 30s. Markets are now pricing in less than one FOMC rate cut this year — a sharp shift from the approximately 2.3 cuts priced in at the start of 2026. Until oil and the long bond find some stability, everything else will likely remain volatile.
Corporate Bond Market Commentary
Investment Grade (IG) Bonds
- IG spreads tightened 1bp to +84bp; total returns were -0.89%.
- IG new issuance was $50.6 billion across 24 borrowers, below the $65 billion estimate. NICs were a more generous 5.7bp, book coverage was 4.4x, attrition was 21%, and deals tightened an average of 30bp from IPT to final pricing.
- This week, issuance surged well over $100 billion with massive deals from Amazon, Salesforce, and Honeywell Aerospace.
- IG fund flows were +$1.9 billion.
High Yield (HY) Bonds
- HY spreads widened 3bp to +313bp; total returns were -0.38% (BBs -0.45%, Bs -0.25%, CCCs -0.39%).
- HY new issuance was $5.35 billion including deals from Applied Digital, SM Energy, Post Holdings, and Versigent.
- HY fund flows were -$182 million; leveraged loan funds saw large outflows of -$1.5 billion on continued concerns over software sector exposure.
Our Take
As the Middle East conflict continued and oil prices moved higher, credit spreads widened further. The Salesforce deal — proceeds earmarked for leveraged share repurchases — came with very large new issue concessions and pushed spreads wider, particularly among other TMT borrowers. This wave of price-insensitive supply was a concern heading into 2026 and will likely continue to pressure IG spreads. It may also create opportunities to step into new situations at more attractive concession levels, especially for unconstrained managers who are underweight or don’t already own these names.
Municipal Bond Market Commentary
- The municipal bond index posted a total return of -0.89% last week.
- Muni yields rose +12, +16, +17, and +15bps at the 1-, 5-, 10-, and 30-year maturities; ratios moved to 60%, 60%, 64%, and 88% at those same tenors.
- Last week’s new issue volume was $12.3 billion ($11 billion tax-exempt). This week’s calendar totals $14.8 billion — the largest weekly total so far this year.
- Fund flows were +$1.669 billion, including $1.041 billion into mutual funds and $628 million into ETFs.
Our Take
The triple headwind of higher Treasury rates, elevated new issue supply, and seasonal weakness in March and April is colliding and adversely affecting municipal bond performance. This weakness could persist if supply remains elevated, rates have not yet peaked, and several more weeks of tax season lie ahead. However, these factors may be setting up a compelling entry point for adding muni exposure in the coming weeks, and investors may want to prepare accordingly.
