Fed Rate Hike Odds Hit 12% as Oil Shock Triggers Stagflation Repricing
Markets reverse six weeks of rate-cut expectations as Brent crude surges past $112 and core inflation holds at 2.7%—testing Powell's final months before transition.
The probability of a Federal Reserve rate hike in April 2026 surged to 12% by March 20—up from zero six weeks earlier—as markets scrambled to reprice monetary policy amid oil prices above $112 per barrel and core inflation proving stickier than the Fed’s December forecasts anticipated.
The shift marks a dramatic reversal in market expectations. Since late January, traders had positioned for two to three rate cuts in 2026, betting the Fed would ease policy as Inflation approached the 2% target. Iran’s closure of the Strait of Hormuz on February 28 disrupted 20% of global crude supply—the largest supply shock in modern oil market history, according to the International Energy Agency—and Brent crude surged from $67 to $112-113 within three weeks. Core PCE inflation, meanwhile, was revised upward to 2.7% for 2026 at the March 18 FOMC meeting, up from the 2.5% December projection, per the Federal Reserve’s latest Summary of Economic Projections.
The Federal Reserve held its benchmark rate at 3.5-3.75% on March 18 in an 11-1 vote, with Council of Economic Advisers Chair Michael Miran dissenting in favor of a 25 basis point cut. Chair Jerome Powell’s post-meeting press conference offered no comfort to markets hoping for near-term easing. “Near term measures of inflation expectations have risen in recent weeks, likely reflecting the substantial rise in oil prices caused by the supply disruptions in the Middle East,” Powell said, according to CNBC. He characterized current inflationary pressure as “murky” and notably refused to rule out further hikes if energy costs bleed into core services inflation.
The Simultaneity Problem
What spooked markets wasn’t oil prices alone—it was the collision of rising yields and falling equities. The 2-year Treasury yield hit 3.90% on March 20, its highest level in months, while the 10-year breached 4.39%. Yields rose 30 basis points across the curve since the Iran conflict began, per Bloomberg data. Meanwhile, the S&P 500 fell 1.5% to 6,506—its fourth consecutive weekly decline and first close below the 200-day moving average since May 2025. The Nasdaq Composite dropped 2.01% to 21,647 as tech valuations came under pressure from higher discount rates.
This pattern—bonds and stocks selling off together—signals uncertainty about whether the Fed faces an inflation problem requiring tighter policy or a growth problem requiring easier policy. “A month ago, no one would have believed this,” Ryan Detrick, chief market strategist at Carson Group, told Fortune. Yardeni Research raised its 2026 stagflation probability to 35% from 20%, while both Morgan Stanley and Bank of America flagged potential rate hikes if oil holds above $80-100 per barrel and inflation persists.
“The war and the spike in commodities across the board has pushed the rate hike percentages higher. Inflation concerns were actually brewing before the Iran war even started in late February.”

Recession or Stagflation?
Markets appear split on which risk dominates. HSBC strategists noted that equity positioning reflects recession concerns more than stagflation fears. “Our regime models show the equity market is now pricing a 35% probability of recession, up from 10% just two weeks ago, while the implied likelihood of stagflation has barely moved, holding at 8%,” HSBC’s Alastair Pinder and Pankaj Agarwala wrote in a March 18 note cited by CNBC.
Economic data offers contradictory signals. The Atlanta Fed’s GDPNow tracker revised first-quarter growth down to 2.3% from 2.7%, while January’s jobs report showed a surprise loss of 92,000 positions—data that would typically argue for easing. Yet core inflation remains elevated: January core PCE hit 3.1%, February headline CPI came in at 2.4%, and March CPI (released April 10) showed headline inflation at 2.8% with core at 3.1%, according to Bureau of Labor Statistics data.
Cross-Market Contagion
The energy shock creates asymmetric impacts across asset classes. Tech-heavy indices face dual pressure: higher Treasury Yields increase discount rates applied to future earnings, while $110+ oil threatens consumer spending that underpins demand for digital services. Energy stocks rallied initially but have since pulled back on recession fears—classic demand destruction concerns overwhelming the supply-side windfall.
Credit markets are tightening. Investment-grade spreads widened 15 basis points in the past two weeks as corporate borrowers face both higher base rates and deteriorating growth expectations. Emerging market currencies sold off sharply against the dollar, with oil importers hit hardest as their terms of trade collapsed.
The Fed’s dilemma is structural. Traditional inflation-fighting tools—rate hikes—work by destroying demand. But oil supply shocks create inflation through scarcity, not excess demand. Hiking rates into a supply-driven inflation surge risks accelerating recession without addressing the underlying energy constraint. This is the classic stagflation trap: monetary policy can suppress demand but cannot conjure additional oil supply from a closed strait.
What to Watch
April’s FOMC meeting on the 30th will test whether current rate hike probabilities translate into actual policy action. Three variables matter most: oil price trajectory (sustained moves above $100 per barrel increase hike odds), March and April inflation prints (releases on April 10 and May 13), and Iran conflict de-escalation prospects. If Brent crude falls back below $90 and core inflation shows sequential deceleration, the rate hike narrative evaporates quickly.
Chair Powell’s final months before the expected transition to Kevin Warsh in early 2027 create additional uncertainty. Markets are gaming not just near-term policy but the Fed’s longer-term reaction function under new leadership. Warsh is viewed as more hawkish on inflation than Powell, which may be pulling forward some hawkish repricing into current pricing.
- Rate hike probability jumped from 0% to 12% in six weeks as oil surged from $67 to $113 and core inflation held at 2.7%
- Simultaneous bond and equity selloffs signal deep uncertainty about whether the Fed faces an inflation or growth problem
- Energy shock creates asymmetric cross-market impacts—tech valuations compressed by higher discount rates while recession fears cap energy stock gains
- April 30 FOMC meeting will test whether current hike odds translate into policy action or fade as oil prices stabilize
The next six weeks determine whether March’s repricing marks a fundamental shift in the Fed’s 2026 trajectory or a temporary panic that fades with oil prices. For now, markets are pricing the worst of both worlds: persistent inflation requiring tighter policy and slowing growth requiring easier policy. Only one can be right.
