Interest Rate Outlook: How the Iran Crisis Is Forcing Central Banks to Rethink the Easing Cycle

The Iran-driven energy shock has upended the global rate cutting consensus. With inflation expectations de-anchoring and oil above $100, the ECB, Fed and BoE face a stagflationary environment that could delay easing by 6-12 months—reshaping fixed income markets and deal financing costs.
Before the Iran escalation, financial markets had priced a benign glide path for global interest rates. The ECB was expected to cut by a cumulative 100 basis points in 2026, bringing the deposit rate to 1.75%. The Fed was priced for three 25bp cuts, and the Bank of England for two. That consensus has been shattered.
Euro area 5-year inflation breakevens have jumped from 2.1% to 2.6% since mid-March, reflecting a fundamental repricing of the inflation outlook. Core CPI, which had been trending toward 2% target across the G7, now faces upside risks of 0.5-1.0 percentage points from energy passthrough effects. The ECB's April 2026 staff projections are expected to revise headline inflation upward to 2.8-3.2% for Q3-Q4 2026.
The Federal Reserve is navigating particularly treacherous waters. Chair Powell has emphasized the data-dependent approach, but the simultaneous weakening of labor markets (initial claims rising to 245,000) and firming inflation expectations create a classic stagflation trap. The FOMC dot plot has shifted from a median of 3 cuts in 2026 to just 1, with two voting members now favoring a hold through year-end.
For the leveraged finance market, the rate repricing is material. High-yield spreads have widened by 85 basis points since February, with CCC-rated credits bearing the brunt (+140bp). The all-in cost of a typical leveraged buyout financing package (Term Loan B + high-yield bond) has increased from approximately 8.5% to 9.8%, adding roughly $13 million in annual interest expense per $1 billion of debt.
Government bond markets are exhibiting unusual behavior. The US 10-year yield has risen 45bp to 4.85%, but the 2s10s curve has steepened sharply as short-end rates price in fewer cuts while the long end adjusts for higher term premium. German Bund yields have jumped from 2.1% to 2.6%, the largest 4-week move since the 2022 ECB pivot.
For M&A dealmakers, the financing cost increase is already affecting activity. Sponsors report that return hurdles are being missed on approximately 30% of deals currently in pipeline, leading to either renegotiations or deal withdrawals. Investment-grade corporate issuance has slowed 25% month-over-month as treasurers adopt a wait-and-see stance on refinancing.
