Iran War at 100 Days: How Energy Shocks Are Reshaping Global Inflation

The Iran war reaches its 100th day this weekend, marking a grim milestone in a conflict that has already reshaped global asset prices and revived inflationary pressures across major economies. Since hostilities began, energy costs and commodity prices have surged, forcing central banks to recalibrate their policy outlooks. The war's impact is now feeding through to consumer prices, with several key economies reporting rising inflation for the first time in months.

Energy Shock Transmits to Core Inflation

The conflict has directly disrupted oil supplies from the Middle East, pushing crude prices above $100 per barrel for sustained periods. Natural gas and other energy commodities have also spiked, raising production and transportation costs worldwide. April's headline CPI already came in at 3.8% year over year, the highest reading since May 2023, and the war's continued escalation threatens to keep inflation elevated. The transmission mechanism is straightforward: higher energy costs increase input prices for virtually every sector, from manufacturing to logistics, which are then passed on to consumers.

Central Banks Face Policy Dilemma

The Federal Reserve and other central banks now confront a difficult trade-off. The war-induced inflation complicates their efforts to ease monetary policy, as rate cuts could exacerbate price pressures. The two macro events that will define the second-half trajectory land within seven days of each other: May CPI on June 10 and the FOMC dot plot on June 17. A second consecutive hot CPI print, above 3.6% YoY, would eliminate the probability of any 2026 rate cuts from consensus pricing, pushing the DXY toward 107 and compressing global liquidity.

Market Implications: Bonds, Equities, and Commodities

Bond markets have already repriced, with the 10-year Treasury yield climbing as rate-cut expectations fade. Equities have been volatile, with defensive sectors like energy outperforming while growth stocks face headwinds from higher discount rates. Commodities broadly benefit from the supply disruptions, but the inflation premium is also eroding real returns. The DXY strength, driven by relative yield differentials, puts pressure on emerging markets and risk assets.

Outlook: Persistent Inflation or Transitory?

The duration of the Iran war is the key variable. If the conflict de-escalates, energy prices could retreat, easing inflation. However, a protracted war risks embedding higher inflation expectations, forcing central banks to maintain restrictive policy longer. The next CPI and FOMC meetings will provide critical signals. For now, markets are pricing in a higher-for-longer rate environment, with significant volatility expected around the June data releases.

Key Takeaways

1. The Iran war's 100th day has pushed energy costs and commodity prices higher, reigniting inflation in major economies.
2. April CPI at 3.8% YoY, the highest since May 2023, and May CPI due June 10 could further pressure the Fed.
3. FOMC dot plot on June 17 will be crucial; a hot CPI may eliminate rate-cut expectations for 2026.
4. Higher energy costs transmit to core inflation through production and logistics costs.
5. Bonds, equities, and currencies are repricing for a higher-for-longer rate environment.
