FOMC March 2026 Decision: Duration Dashboard

The FOMC's March 17–18 meeting produced the week's most consequential repricing event. The Committee voted 11–1 to maintain the federal funds rate at 3.50–3.75%, with the dissent favoring a 25bp cut. While the median dot plot still projects one 25bp cut in 2026, the distribution shifted meaningfully: seven of 19 participants now see no cuts this year, up from six in December. The Summary of Economic Projections raised the 2026 PCE inflation forecast to 2.7% from 2.4% — the largest single-meeting upward revision since June 2022 — while adding explicit language acknowledging the economic uncertainty stemming from the Middle East conflict. As detailed in our March 15 preview report, the pre-FOMC setup pointed to a hawkish outcome, and the Committee delivered beyond consensus expectations.

Wednesday's PPI report amplified the hawkish narrative. February producer prices rose 0.7% month-over-month — more than double the 0.3% consensus — with core PPI also surprising at +0.5%. Year-over-year PPI accelerated to 3.4%, the highest reading since early 2025. The report arrived just hours before the FOMC decision, effectively reinforcing the Committee's decision to upgrade inflation projections. The strength was broad-based, with final demand goods up 1.1% and services rising 0.5%, suggesting pipeline price pressures that may flow through to consumer prices in coming months.

Supply dynamics compounded the rate repricing. The Treasury Department sold $606 billion in securities across nine auctions during the week — a pace that reflects the federal government's persistent financing needs against a backdrop of annual deficits exceeding $1.9 trillion. Gross national debt surpassed $39 trillion for the first time on March 17. The sheer volume of issuance competing for fixed income capital adds structural upward pressure on yields, particularly at the long end where term premium has expanded. Investment grade corporate issuance also remained elevated, with the prior week having produced a record single-day volume of $65.8 billion, though the March 16–20 window likely saw reduced activity given the FOMC meeting and heightened volatility.

Credit Pulse: Spreads Widen as Treasury Yields Rise

Credit markets absorbed the week's hawkish repricing with notable composure, though the direction of spread movement was clearly wider. High yield OAS expanded 22 basis points to 320bp — the largest weekly widening since early March when the Iran conflict began — but remains near the middle of its 5-year range at the 42nd percentile. Investment grade spreads edged 4bp wider to 92bp, well above the historic 71bp low touched in late January but still in the middle of the distribution at the 58th percentile. As discussed in our March 8 report on the Iran oil shock, the initial credit market response to geopolitical disruption has been measured relative to the magnitude of the underlying event.

The VIX edged lower by 0.41 points to 26.78 despite equity weakness, though its 90th percentile reading signals that implied volatility remains well above normal levels. The S&P 500 declined for a fourth consecutive week, falling approximately 1.9% and breaking below its 200-day moving average on Thursday for the first time in over 200 sessions — a technically significant event that may trigger systematic selling strategies. The Russell 2000 entered formal correction territory, and energy was the only positive S&P 500 sector for the week. CDX credit default swap indices rose to 9-month highs — a signal that has historically preceded further spread widening.

Gold's sharp decline — down approximately 10% from record highs to roughly $4,500 per ounce in its worst weekly performance since 2011 — provided an important cross-asset signal for fixed income investors. The selloff reflected rising real yields, a classic deleveraging dynamic where leveraged positions facing margin calls liquidate even safe-haven assets to meet collateral requirements. This type of forced selling, combined with the equity correction, suggests that cross-asset risk is more interconnected than credit spreads alone would indicate.

Federal Reserve Policy Outlook — FOMC March 2026 Decision Implications

The March FOMC meeting represented a decisive shift in the Committee's risk assessment. By raising the 2026 core PCE forecast to 2.7% from 2.5% while acknowledging Middle East uncertainty for the first time in an official statement, the Fed signaled that it views the current inflation impulse — driven by energy costs, tariff pass-through, and resilient demand — as more persistent than previously anticipated. The GDP growth forecast was modestly upgraded to 2.4%, while the longer-run neutral rate estimate edged to 3.0%, reinforcing the structural case for higher policy rates.

The dot plot mechanics deserve close attention. While the median still shows one cut in 2026, Powell noted that several participants shifted from two cuts to one, and seven of 19 now project no cuts this year. The market's response — pricing zero cuts through year-end — went further than the Committee's central tendency, reflecting a view that the balance of risks has shifted definitively toward higher-for-longer. Governor Waller's Friday revelation that the oil shock reversed his inclination to dissent for a cut illustrates how rapidly the policy calculus has shifted since the Iran conflict began on February 28. The contrast with the January FOMC meeting, when the Committee maintained a more balanced stance — as analyzed in our February 1 FOMC review — underscores the speed of this policy recalibration.

Iran Conflict and Energy Markets — Strait of Hormuz Impact

The US-Israeli military campaign against Iran, now in its third week, continued to dominate cross-asset risk sentiment. The Strait of Hormuz — through which approximately 20% of global oil supply transits — has been effectively closed since early March, creating the most significant energy supply disruption since the 1970s. This week's developments included reported Israeli strikes on Iran's South Pars gas field and a retaliatory Iranian attack on Qatar's Ras Laffan LNG facility. On Friday, reports of Pentagon preparations for potential ground operations and consideration of seizing Iran's Kharg Island oil export hub added to market uncertainty.

WTI crude closed the week near $98/barrel, with Brent above $108. Analysts at several major banks have warned that a prolonged closure could push Brent toward previous cycle highs. The IEA coordinated a historic emergency release from 32 member countries, with the US committing 172 million barrels from the Strategic Petroleum Reserve. For fixed income markets, the primary transmission mechanism runs through inflation expectations: 5-year breakeven inflation rates have risen materially since the conflict began, compressing real yields less than nominal yields have risen and adding to the term premium embedded in longer-duration bonds.

Global Central Bank Convergence

In an unusual convergence, the Fed, ECB, Bank of England, and Bank of Japan all delivered rate decisions within a 24-hour window — and none cut rates. The ECB held at 2.00%, raising its 2026 inflation forecast to 2.6% and citing Middle East energy risks. The Bank of England held at 3.75% unanimously, warning that CPI could run between 3.0–3.5% over the coming quarters. The Bank of Japan held at 0.75%, rejecting a proposal to hike to 1.0% in an 8–1 vote. This synchronized hold marks a clear end to the global easing cycle that characterized late 2024 and 2025, with policy divergence now centered on which central banks may need to tighten further rather than how quickly to ease.

Week Ahead: PCE Inflation and Iran Developments

• Trump Iran Ultimatum Deadline (Monday, March 23): The President's threat to escalate strikes if the Strait of Hormuz is not reopened within 48 hours expires Monday. The resolution or escalation of this standoff will likely set the tone for energy markets and broader risk sentiment throughout the week.
• Existing Home Sales (Tuesday, March 24): February data expected to show continued pressure from elevated mortgage rates. Any meaningful decline would reinforce the housing sector's sensitivity to the higher-rate environment.
• Durable Goods Orders (Wednesday, March 25): February data will provide a read on business investment intentions amid trade policy uncertainty and rising input costs.
• Final Q4 2025 GDP Revision (Thursday, March 26): The third revision to Q4 GDP could confirm whether the preliminary 0.7% reading — a notable deceleration from prior quarters — will be revised further.
• February PCE Price Index (Friday, March 27): The Fed's preferred inflation measure arrives with heightened significance given this week's hot PPI data and the FOMC's revised projections. A core PCE reading above 0.3% m/m would further validate the Committee's hawkish shift and likely push rate-cut expectations even further out.

US Economic Positioning and Global Context

The US economy enters a challenging phase where multiple headwinds converge. The combination of fiscal deficits now exceeding $1.9 trillion annually (with gross national debt surpassing $39 trillion for the first time on March 17), the Iran-driven energy shock, and ongoing trade policy uncertainty — including the USTR's new Section 301 investigations targeting 60 trading partners — creates a complex backdrop for fixed income markets. The government sold $606 billion in Treasury securities across nine auctions during the week, underscoring the relentless pace of issuance that competes with private credit for investor capital.

The dollar weakened modestly despite the geopolitical environment, with the DXY index declining approximately 1% to near 99.50, as hawkish pivots from the ECB and BOE reduced the US rate advantage relative to peers. For fixed income allocators, the 30-year yield at the 98th percentile of its 5-year range reflects the combination of these structural forces: persistent inflation risk, elevated supply, and the growing term premium that investors demand for duration exposure in an uncertain environment. The question for the coming weeks is whether the economic data — particularly next Friday's PCE report — will confirm the inflationary trajectory the FOMC has projected, or whether the growth slowdown (Q4 GDP at 0.7%) will reassert itself as the dominant narrative.
