Duration & Credit Pulse
Executive Summary
Bottom Line: The CPI March 2026 report delivered a bifurcated inflation picture—headline at +0.9% monthly on a 21.2% gasoline spike, but core at just +0.2%—while an Iran ceasefire drove the week's dominant repricing event. Treasury yields declined 3–4 basis points across the front end as oil's collapse briefly resurrected rate-cut hopes, though the 30-year held firm at 4.91% (96th percentile). Credit spreads tightened materially, with high yield OAS compressing 30 basis points to 266bp, but record-low consumer sentiment at 47.6 and the collapse of weekend peace talks cloud the outlook heading into bank earnings and retail sales data.

Bull Steepening Amid Iran Ceasefire Rally
Curve Analysis: Treasury markets displayed classic bull steepening behavior as the Iran ceasefire drove front-end yields lower while the long end held firm. The 2s30s spread widened 5 basis points to 111bp as the 2-year fell 4bp while the 30-year was unchanged—reflecting market conviction that near-term rate relief became more plausible following the oil price collapse, even as persistent fiscal deficits and inflation uncertainty maintained the long-end term premium. The 30-year's position at its 96th historical percentile underscores the structural repricing that has occurred since the conflict began in late February.
The week's price action told a story of competing forces. Tuesday evening's ceasefire announcement triggered an immediate repricing in rates, with the 10-year yield touching 4.24% intraday Wednesday as WTI crude collapsed over 16% to $94 per barrel. However, Friday's March CPI data—headline at +0.9% monthly on a 21.2% gasoline surge—reminded markets that the inflation damage from the Iran conflict has already embedded in the data, even as core CPI's benign 0.2% reading offered the Fed an argument to look through the energy shock. The front end's outperformance reflected growing expectations for eventual policy relief, as discussed in our prior week's analysis of the March employment data.
Iran Ceasefire and Credit Spread Dynamics
| Metric | April 3, 2026 | April 10, 2026 | Weekly Δ | 5-Year Percentile |
|---|---|---|---|---|
| IG OAS | 79 bp | 76 bp | −3 bp | 27th %ile (middle range) |
| HY OAS | 296 bp | 266 bp | −30 bp | 16th %ile (low/tight) |
| VIX Index | 23.87 | 19.23 | −4.64 | 52nd %ile (middle range) |
The ceasefire triggered the most significant weekly credit rally since the conflict began. High yield spreads compressed 30 basis points to 266bp, reversing roughly half of the widening that occurred from the pre-war tights of 284bp in January to the late-March peak near 325bp. The VIX's decline to 19.23 from 23.87 represented its sharpest weekly drop since April 2025. Investment grade spreads tightened a more modest 3 basis points to 76bp, consistent with the sector's lower sensitivity to risk-on/risk-off dynamics. Equities joined the rally, with the S&P 500 posting its best weekly gain since November at approximately +3.6%.

US Macroeconomic Assessment – Inflation Bifurcation Complicates the Outlook
The week of April 6–10 delivered a paradoxical macro picture: headline inflation accelerated sharply while underlying price pressures moderated, consumer confidence collapsed to historic lows while labor markets remained functional, and growth indicators softened further even as the ceasefire offered potential relief from the primary economic headwind. This bifurcation creates the most challenging policy environment for the Federal Reserve since the 2022 inflation crisis.
CPI reveals the war's inflation footprint: Friday's March CPI report captured the first full month of the Iran conflict's impact on consumer prices. Headline CPI rose 0.9% month-over-month—the largest monthly increase since June 2022—pushing the year-over-year rate to 3.3%, its highest level since May 2024. Gasoline prices drove the increase, rising 21.2% in March—the largest single-month increase in BLS history. Energy costs broadly surged 10.9% for the month. Yet core CPI painted a markedly different picture, rising just 0.2% monthly and 2.6% annually, both a tenth below consensus expectations. Medical care, personal care, and used vehicle prices all declined, while shelter costs rose a manageable 0.3%. The bifurcation between headline and core represents the key analytical challenge for rate-setting authorities.
Consumer confidence reaches historic depths: The University of Michigan's preliminary April consumer sentiment index fell to 47.6—an all-time record low in the survey's 70+ year history—surpassing even the depths of the 2022 inflation crisis and the 2008 financial crisis. Every component and every demographic group declined. One-year inflation expectations surged a full percentage point to 4.8%, while five-year expectations rose to 3.4% from 3.2%. The survey director noted that 98% of interviews were completed before the ceasefire announcement, meaning the data reflects peak war-related pessimism. Subsequent readings should improve if the ceasefire holds, though the naval blockade announcement complicates that expectation.
Growth indicators continue to soften: Thursday's final Q4 2025 GDP revision showed the economy grew at just +0.5% annualized, revised down from the +0.7% second estimate and a sharp deceleration from Q3's +4.4% pace. The October–November 2025 government shutdown subtracted approximately 1.0 percentage point from Q4 growth. Monday's ISM Services PMI for March came in at 54.0 versus 55.0 consensus, maintaining expansion but revealing troubling internals: the employment sub-index collapsed to 45.2 (down 6.6 points, the lowest since December 2023), while prices paid surged to 70.7—the highest since October 2022. This combination of contracting service-sector employment alongside rising input costs is a textbook stagflationary signal. Weekly initial jobless claims rose to 219,000, above the 210,000 consensus, though continuing claims fell to 1,794,000—the lowest since May 2024.

Federal Reserve Policy Outlook – FOMC Minutes Reveal Two-Sided Rate Risk
Wednesday's release of the March 17–18 FOMC minutes—coinciding with the ceasefire rally—revealed a committee wrestling with heightened uncertainty in both directions. The Fed held rates at 3.50–3.75% with an 11-1 vote; Governor Stephen Miran dissented in favor of a 25 basis point cut, arguing policy remained too restrictive. Governor Waller, who dissented for a cut in January, voted with the majority this time—a notable hawkish shift from a key bellwether. As we analyzed in our March 22 FOMC coverage, the committee had been moving toward a more cautious posture, and these minutes confirmed that trajectory.
The minutes' most consequential revelation was that several participants judged there was a strong case for describing future rate decisions as "two-sided"—meaning rate hikes, not just cuts, could be necessary. The committee acknowledged that progress in reducing inflation had stalled in recent months and that both upside risks to inflation and downside risks to employment had increased with developments in the Middle East. The March dot plot showed 7 of 19 participants projecting no cuts at all in 2026, up from 6 in December, though the median projection remained one 25bp cut.
Rate expectations shifted throughout the week. The ceasefire temporarily pushed year-end cut probability to approximately 43% on Wednesday morning, but by Friday's close, markets settled on roughly 25% probability of a single cut by December. The April 28–29 meeting is priced at near-certainty for a hold. Chair Powell's term expires May 15, with nominee Kevin Warsh—who has publicly supported easier monetary policy—still awaiting Senate confirmation, adding an unusual layer of institutional uncertainty.
Treasury Auction Demand Signals Institutional Confidence
Wednesday's $39 billion 10-year note reopening delivered the week's most constructive signal for the rates market. The auction priced at a high yield of 4.28% with a bid-to-cover ratio of 2.43x. Indirect bidders—primarily foreign central banks and institutional accounts—took 65.3% of the competitive allocation, while primary dealers were left holding just 10.8%, well below average. This marked a notable improvement from the weak 2-year, 5-year, and 7-year auctions in late March, which all tailed and saw elevated dealer participation, as discussed in our March 29 report. The strong reception suggests institutional demand for intermediate duration remains healthy at current yield levels, even as fiscal concerns about debt-to-GDP trajectories persist. The MOVE Index declined approximately 20% on the week, the sharpest weekly drop since mid-2023, reflecting the normalization of rate volatility expectations following the ceasefire.
Week Ahead: Bank Earnings Meet Geopolitical Reset
- Naval Blockade Implications (Ongoing): Trump's Sunday announcement of a full naval blockade of the Strait of Hormuz following the collapse of Islamabad peace talks resets the geopolitical risk premium. Oil prices and Treasury yields will respond to developments at Monday's open.
- Bank Earnings (April 13–15): Goldman Sachs reports Monday, followed by JPMorgan, Citigroup, and Wells Fargo on Tuesday. Trading revenue commentary will reveal how banks navigated war-related volatility, while loan loss provisions will signal forward credit expectations.
- PPI Inflation (April 14): March Producer Price Index will show whether energy cost pass-through is moving upstream through the supply chain. Any upside surprise would reinforce concerns about second-round inflation effects from the Iran conflict.
- Retail Sales (April 15): March data represents the first clean read on consumer spending behavior amid gasoline prices above $5 per gallon. Consensus expects weakness, but pre-war stockpiling effects may create noise.
- Fed Speakers (Throughout Week): Multiple Fed officials are scheduled to speak following the blackout period, providing the first formal reactions to the CPI data and ceasefire developments. Markets will parse any commentary on whether the inflation spike is viewed as transitory.
US Economic Positioning and Global Context
The ceasefire temporarily eased the geopolitical premium that had accumulated across global markets since the conflict's onset on February 28, but the fragility of the arrangement—confirmed by the weekend collapse—underscores the persistent repricing required for a world where energy supply disruptions carry military dimensions. The DXY's decline to approximately 98.7 reflected the unwinding of safe-haven flows, marking its weakest weekly close since January, while gold held near $4,787 as investors maintained hedges against renewed conflict escalation.
The structural challenge for fixed income investors extends beyond the immediate geopolitical cycle. The 30-year Treasury's position at its 96th historical percentile—unchanged on the week despite the ceasefire rally—reflects the market's assessment that term premium must remain elevated given the combination of persistent fiscal deficits (CBO projects debt-to-GDP rising from 100% to 120% by 2036), ongoing inflation uncertainty, and the prospect of a leadership transition at the Federal Reserve. This week's 10-year auction demonstrated that institutional demand exists at current levels, but the durability of that demand depends on whether the ceasefire evolves into a lasting resolution or, as now appears more likely, reverts to active conflict. For institutional portfolios, the bifurcation between compressed public credit spreads and emerging private credit stress represents an asymmetric risk that current pricing does not adequately reflect.

Frequently Asked Questions
What did the March 2026 CPI report show about inflation?
Headline CPI surged 0.9% month-over-month to 3.3% year-over-year, driven primarily by a record 21.2% monthly increase in gasoline prices stemming from the Iran war oil shock. However, core CPI—which excludes food and energy—rose just 0.2% monthly and 2.6% annually, both below consensus estimates, indicating that underlying inflation pressures remained contained outside the energy sector.
How did the Iran ceasefire affect Treasury yields and credit spreads?
The two-week ceasefire announced on April 7 drove a sharp risk-on move across fixed income markets. The 10-year Treasury yield fell as much as 10 basis points intraday on Wednesday before settling the week down 3 basis points at 4.32%. High yield credit spreads compressed 30 basis points to 266bp, and the VIX declined 4.64 points to 19.23 as oil prices fell over 13% for the week.
Why did the University of Michigan consumer sentiment index hit a record low?
The preliminary April reading of 47.6 marked the lowest level in the survey's 70+ year history. Elevated gasoline prices, war-related uncertainty, and rising inflation expectations—one-year expectations reached 4.8%—drove broad-based declines across all income levels and demographics. Notably, 98% of responses were collected before the ceasefire, so subsequent readings may improve if energy prices normalize.
What did the FOMC minutes reveal about rate hike risk in 2026?
The March 17–18 minutes showed several participants believed future rate decisions should be described as "two-sided," explicitly acknowledging that rate increases—not just cuts—might become necessary. Seven of 19 members projected no cuts in 2026, and the committee noted that progress in reducing inflation had stalled. Markets now price roughly a 25% probability of one cut by year-end.
