Duration & Credit Pulse
Executive Summary
Bottom Line: The FOMC March 2026 meeting arrives at a precarious juncture as Q4 GDP was revised sharply lower to just 0.7% while core PCE re-accelerated to 3.1%, a combination that pushed Treasury yields higher across the curve in a near-parallel sell-off. The 30-year yield reached 4.91%, its 95th percentile over five years, as the bond market signaled that inflation risk—amplified by the Iran-driven oil shock and prospective Section 301 tariffs—outweighs the deteriorating growth backdrop. Credit spreads widened measurably, with high yield OAS moving to 298 basis points (+17 bp) and investment grade to 88 bp (+9 bp), though both remain in the middle range of their historical distributions.
Duration Dashboard — FOMC March 2026 Week
| Maturity | March 8, 2026 | March 15, 2026 | Weekly Δ | 5-Year Percentile |
|---|---|---|---|---|
| 2‑Year | 3.56% | 3.72% | +16 bp | 43rd %ile (middle range) |

Near-Parallel Sell-Off as Stagflation Repricing Accelerates
Curve Analysis: The sell-off was notably parallel, with yields rising 13–16 basis points across maturities. The 2s10s spread edged lower to 56 basis points from 58bp, and the 2s30s narrowed marginally to 119bp from 120bp. This pattern reflects broad-based inflation repricing rather than growth-differentiated positioning. The front end moved more than typical for a week in which rate expectations shifted only modestly, suggesting markets are embedding a higher-for-longer premium across the entire curve. The 30-year yield at 4.91%—its 95th percentile over five years—now sits within striking distance of the 5% threshold last approached in late January.
The most instructive signal of the week was Treasury markets' failure to rally on the weakest GDP report in several years. When 10-year yields rise 14 basis points in the same week that growth is revised to 0.7%, the market is communicating a clear signal: inflation risk currently outweighs growth risk in the rate-setting calculus. The combination of energy prices near $100/barrel, a prospective tariff rebuild via Section 301 investigations, and core PCE re-accelerating to 3.1% has established a price floor that is weighing more heavily than softening activity data. As documented in our March 8 report, the Iran-driven oil shock was already reshaping fixed income dynamics, but this week's data releases confirmed the stagflationary impulse is broadening beyond energy.
Credit Pulse — Spreads Widen as Risk Repricing Broadens
| Metric | March 8, 2026 | March 15, 2026 | Weekly Δ | 5-Year Percentile |
|---|---|---|---|---|
| IG OAS | 79 bp | 88 bp | +9 bp | 51st %ile (middle range) |
| HY OAS | 281 bp | 298 bp | +17 bp | 38th %ile (middle range) |
| VIX Index | 29.49 | 27.19 | −2.30 | 91st %ile (extreme) |
Credit markets widened meaningfully but in an orderly fashion, with high yield OAS rising 17 basis points to 298bp and investment grade widening 9bp to 88bp. To provide context, high yield at the 38th percentile and IG at the 51st remain well within normal historical ranges—a notable contrast to the VIX at its 91st percentile, which suggests equity markets are pricing considerably more risk than credit. The VIX itself declined 2.30 points from the prior week's spike following the Iran escalation, though it remains firmly in elevated territory. The S&P 500 closed at approximately 5,632 on Friday, posting its third consecutive weekly decline and reaching its lowest level since mid-December 2025—roughly 5% below the January 27 all-time high. The Nasdaq fell below its 200-day moving average for the first time since May 2025, reinforcing the broader risk-off tone.
High yield's widening from multi-decade tights near 284bp in February to 298bp represents a measured repricing rather than distress. However, the emerging private credit stress warrants monitoring: Blue Owl Capital's decision to permanently halt redemptions at its OBDC II fund and proceed with orderly liquidation signals a pocket of credit deterioration. Morningstar DBRS reported the downgrade-to-upgrade ratio reached 3.3x over the trailing 12 months, with S&P Global projecting speculative-grade defaults near 4% through September 2026. These are not alarming levels in isolation, but they indicate the credit cycle is maturing at a pace that current spread levels do not fully reflect.
US Macroeconomic Assessment — Stagflation Signals Multiply
The week of March 9–13 delivered a data combination that the Federal Reserve has not confronted since the early 1980s: sharply decelerating growth alongside re-accelerating inflation, compounded by an active geopolitical supply shock. The Q4 GDP second estimate released Thursday confirmed that the US economy grew at just 0.7% annualized in the final quarter of 2025, half the advance estimate of 1.4% and well below the 1.5% consensus. This represents a dramatic deceleration from Q3's 4.4% pace, with exports revised lower to −3.3% (from −0.9%) and consumer spending trimmed to 2.0% (from 2.4%). The government shutdown that began in November subtracted approximately one percentage point from the quarter's growth. Full-year 2025 GDP settled at 2.1%, down from the initial 2.2% estimate and 2024's 2.8%.
Inflation running above target on multiple measures: January's core PCE—the Fed's preferred gauge—accelerated to 3.1% year-over-year from 3.0%, with the monthly reading at a firm 0.4%. This leaves core PCE 110 basis points above the 2% target. February CPI, released Tuesday, came in at consensus with headline at 2.4% year-over-year and core at 2.5%, with shelter costs rising just 0.2%—a constructive signal. However, this data entirely predates the oil price surge, rendering it backward-looking for policy purposes. More concerning was apparel's 1.3% monthly jump—the largest since September 2018—which may represent early tariff pass-through from the Section 122 levies enacted in February.
Consumer confidence deteriorating: The University of Michigan consumer sentiment index fell to 55.5 in the preliminary March reading, the lowest of 2026, with the survey director noting that interviews conducted after the Iran conflict began reversed initial gains entirely. One-year inflation expectations held at 3.4%, halting six consecutive months of decline. January durable goods orders came in flat versus a 1.3% consensus expectation, reinforcing the picture of an economy losing momentum. Initial jobless claims for the week ending March 7 were 213,000, modestly better than expectations, though the labor market's lagged response to economic weakness means current claims data offers limited forward guidance. The −92,000 nonfarm payrolls from the prior week's release continued to weigh on sentiment.
Oil shock embedding into the real economy: WTI crude traded near $98–99/barrel through the week with Brent exceeding $103, representing an approximately 47% increase from pre-conflict levels near $67. The Strait of Hormuz remains effectively closed, with Iran having laid approximately a dozen mines in the waterway as the US-Israel military campaign entered its second full week. The EIA's March 10 Short-Term Energy Outlook projected Brent above $95/barrel for the next two months, though this assumes disruptions ease—a substantial assumption given the conflict's trajectory. The Congressional Research Service warned that a prolonged disruption would create conditions without historical precedent for the oil market.
Federal Reserve Policy Outlook — FOMC March 2026 Decision Preview
The Federal Reserve enters its March 17–18 meeting with markets pricing a 99%-plus probability of holding the federal funds rate at 3.50–3.75%. The far more significant development is the near-complete evaporation of rate cut expectations for 2026. Bloomberg reported that traders are no longer fully pricing in even a single cut this year, with CME FedWatch pointing to at most one reduction in December. Goldman Sachs pushed its first-cut forecast from June to September. The Employ America FOMC preview, published March 14, anticipated that the median dot may sit on a knife-edge, with half the Committee projecting no cuts for 2026.
This week's data reinforces the case for extended patience. With core PCE at 3.1% and oil prices embedding additional inflationary pressure, the Committee has limited room for easing even as growth deteriorates. The updated Summary of Economic Projections will likely show downward revisions to GDP growth (from the December projection of approximately 2%) and upward revisions to inflation. The question is whether officials signal willingness to tolerate below-trend growth to maintain anti-inflation credibility, or whether they introduce language acknowledging the supply-side nature of current inflation pressures. The confirmation of Kevin Warsh as the next Fed Chair, set to succeed Powell, introduces a hawkish tilt to the medium-term outlook that fixed income markets are already beginning to price. Four major central banks meet the same week—the ECB, BOJ, and BOE alongside the Fed—all confronting the same energy-driven inflation challenge, with synchronized hold decisions the likely outcome.
Trade Policy — Section 301 Investigations Signal Tariff Rebuild
The week saw a meaningful escalation in trade policy as USTR launched Section 301 investigations into 16 major trading partners on March 11 for structural excess capacity, followed by investigations into approximately 60 countries on March 13 under forced labor provisions. These represent the administration's primary legal pathway to rebuild tariff authority after the Supreme Court's February 20 ruling that struck down IEEPA-based tariffs—a development we analyzed in detail in our February 22 report. A temporary 10% Section 122 tariff remains in effect through July 24, and Treasury Secretary Bessent indicated that tariff rates would return to pre-ruling levels within five months. For fixed income markets, the tariff rebuild creates an additional inflation channel that operates independently of the oil shock, complicating the Fed's ability to look through supply-side price pressures as temporary.
Week Ahead: Four Central Banks and Key US Data
- FOMC Meeting (March 17–18): Rate decision, updated dot plot and Summary of Economic Projections. Most consequential meeting of 2026 as the Committee must formally address the stagflation dynamic. Powell's press conference will be scrutinized for any shift in the balance between growth and inflation objectives.
- ECB Rate Decision (March 17): Expected to hold at 2.00%, with revised projections incorporating the oil shock. European energy exposure makes this decision particularly consequential for global rate differentials.
- BOJ Rate Decision (March 18–19): Expected to hold at 0.75%, though yen weakness past 160/dollar could accelerate the timeline for the next hike. Any hawkish surprise would add to global bond selling pressure.
- BOE Rate Decision (March 19): UK CPI already at 3.0% in January, with Deutsche Bank projecting nearly 4% if the conflict persists. A hold is anticipated, though the Bank's forward guidance will be closely watched.
- US Retail Sales (March 17): February data provides the first reading on consumer behavior following the initial oil price spike and negative payrolls. A weaker-than-expected print would reinforce the growth side of the stagflation equation.
US Economic Positioning and Global Context
The US economy's position has deteriorated notably since the 10-year yield briefly traded below 4% just three weeks ago, as covered in our March 1 report. The DXY strengthened to approximately 100.50 on the week—a 3.5-month high driven by safe-haven flows and widening interest rate differentials. Gold traded in the $5,040–5,114 range, pulling back modestly from weekly highs above $5,195 as rising real yields partially offset geopolitical demand.
The partial DHS government shutdown entered its 27th day with no resolution in sight, adding fiscal policy dysfunction to the list of headwinds. The debt ceiling X-date approaching mid-2026 represents another potential source of Treasury market volatility. Corporate bond issuance had been running 12.4% above prior-year levels through February at $484.9 billion, though this week's elevated volatility and the approaching FOMC meeting likely suppressed primary activity. Bond fund flows remained positive through early March, with taxable bond funds attracting $17.3 billion for the week ending March 4, though investor preference is shifting decisively toward short-to-intermediate duration strategies as the long end reprices.

Frequently Asked Questions
What does the Q4 GDP revision to 0.7% mean for Federal Reserve policy in March 2026?
The sharp downward revision to 0.7% annualized growth confirms a significant economic slowdown, but with core PCE simultaneously accelerating to 3.1%, the Fed faces a stagflationary bind. The Committee is expected to hold rates at 3.50–3.75% at the March 17–18 meeting, with the updated dot plot likely showing fewer projected cuts for 2026 than the December projections indicated.
Why are Treasury yields rising despite weak economic growth?
Treasury yields are being driven primarily by inflation expectations rather than growth expectations. The Iran-related oil shock has pushed WTI crude near $100/barrel, core PCE has re-accelerated above 3%, and Section 301 trade investigations signal additional tariff-driven price pressures ahead. The bond market is assigning a higher probability to sustained above-target inflation than to imminent recession.
How are credit spreads responding to the stagflation risk in March 2026?
Credit spreads widened moderately, with high yield OAS moving to 298bp (+17 bp) and investment grade to 88bp (+9 bp). Both remain in the middle range of their 5-year historical distributions despite the VIX sitting at its 91st percentile, indicating credit markets have not fully repriced for the deteriorating fundamental backdrop and elevated geopolitical risk.
What is the significance of the 30-year Treasury yield approaching 5%?
The 30-year yield at 4.91% sits at its 95th percentile over five years, reflecting elevated long-term inflation expectations, growing fiscal concerns related to deficit spending near 7% of GDP, and a rising term premium demanded by investors for duration risk. A sustained move above 5% would have meaningful implications for mortgage rates, corporate borrowing costs, and equity valuations.
