Iran War Sparks Rate Hike Fears Across Europe

Central banks across Europe are facing increasing market pressure to raise interest rates. This surge is driven by escalating energy costs attributed to the ongoing conflict in Iran, which has revived concerns about a new wave of inflation.

Money markets are now pricing in rate hikes from the European Central Bank (ECB), the Swiss National Bank (SNB), and Sweden's Riksbank before the close of 2026. These developments come as crude oil prices have climbed above $119 a barrel, reaching their highest point since mid-2022.

The current situation evokes memories of 2022, when central banks were slow to respond to an energy shock that subsequently fueled broader consumer price increases. Many policymakers are concerned about avoiding a repeat of that scenario.

Officials, particularly at the ECB, have emphasized that temporary oil price spikes should not significantly alter the medium-term inflation outlook. However, a sustained increase could lead to approximately a one-percentage-point rise in euro zone inflation, with the UK facing a similar impact if oil and gas prices remain elevated.

Central bankers are grappling with a core dilemma: should they follow the principle of looking past temporary supply shocks, or should they be guided by recent, difficult experiences with inflation. While the textbook approach suggests monetary policy tightening could worsen output losses from supply shocks, the risk of second-round effects from current energy price movements might compel action.

However, some economists caution that market expectations may be overly ambitious. The Swiss National Bank, for instance, is considered less likely to raise rates given the strengthening Swiss franc. Market pricing may also reflect a rapid unwinding of previous bets on interest rate cuts.
