WASHINGTON — The Federal Open Market Committee concludes its two-day March meeting Wednesday afternoon, with the rate decision itself — a hold in the 3.50%–3.75% range — treated as a foregone conclusion by virtually every market participant. CME FedWatch data shows 99% probability assigned to an unchanged decision. What remains deeply uncertain, and what will move markets, is the content of the quarterly Summary of Economic Projections and the tone of Chair Jerome Powell's press conference at 2:30 p.m. Eastern.

The SEP, commonly known as the dot plot, will offer the committee's first formal economic forecasts since the outbreak of the Iran war in late February — a conflict that has pushed Brent crude above $100 per barrel, elevated inflation expectations, and simultaneously begun to weigh on consumer sentiment and corporate investment. The result is a stagflationary backdrop that puts the Fed in an extraordinarily difficult position: raising rates to fight inflation risks tipping a softening economy into recession, while cutting rates to support growth risks unleashing another wave of price pressures.

Economists expect the dot plot to reflect this dilemma through a wide dispersion of member forecasts. Prior to the Iran conflict, consensus had coalesced around one rate cut in 2026. Wednesday's projections could show some members favoring no cuts at all, while more dovish members retain their one-cut view. The median forecast shifting from one cut to zero would represent a significant hawkish surprise with immediate implications for rate-sensitive equities, mortgage rates, and high-yield credit spreads.

The timing of the meeting is politically complex. Chair Powell's term expires May 15, and the White House has nominated former Fed Governor Kevin Warsh as his successor. The DOJ has issued grand jury subpoenas to the Fed related to a Capitol renovation project, and Powell responded publicly — a historic step for a sitting Fed chair. Markets have largely remained calm amid the political turbulence, but Powell's final scheduled press conference as chair carries unusual symbolic weight, and any deviation from his typically measured messaging could amplify volatility.

Fixed income markets are reflecting the uncertainty. The 10-year Treasury yield stands at 4.21%, up modestly on the day after the hot PPI print, while the 30-year yield sits near 4.85%. The yield curve has steepened modestly over the past week, suggesting markets are pricing in inflation risk at the long end without expecting the Fed to aggressively tighten. The 30-year fixed mortgage rate currently sits at 6.21%, a level that has nonetheless supported a 3.2% uptick in mortgage applications as buyers rush to lock in ahead of anticipated further increases.

For equity investors, the key question is whether Powell acknowledges the Iran-driven energy shock as transitory — a framing that would support risk assets — or frames it as a persistent inflation threat that could delay any future easing. The former would likely trigger a relief rally; the latter could extend the morning's broad-based selling. With the S&P 500 less than 5% below all-time highs, the margin for disappointment is thin.
