The European Central Bank is being forced to accelerate its tightening of monetary policy as the Middle East crisis has pushed the eurozone into a classic stagflation trap, triggering a sharp rise in inflation amid slowing economic growth.

According to a new macroeconomic report from UBS titled "Prospects for the European Economy," the ECB is expected to deliver at least two interest rate hikes of 25 basis points each this year, with the baseline scenario projecting rates to reach 2.5% by September.

This shift is largely driven by persistently high fuel prices, which have already begun to seep into a broad range of consumer goods. UBS emphasizes that the balance of risks has now shifted toward earlier and more aggressive rate increases. The ECB Governing Council may raise interest rates as soon as its meeting on April 30 if it detects signs of second-round inflationary effects.

Frankfurt is faced with a difficult choice: attempting to curb imported energy inflation through high rates poses a direct risk of stifling the already weak economic growth in Europe. Analysts warn that their forecasts could prove "too soft" if the logistical blockade in the Persian Gulf extends into the latter half of the year.

While the ECB prepares to tighten its stance, other European central banks are adopting a wait-and-see approach. The Bank of England is expected to take a prolonged pause, with its next significant action likely being a rate cut at the end of 2026.

The Swiss National Bank plans to keep interest rates steady at zero until mid-2027, as a strong franc provides the country with a reliable shield against imported inflation. The Swedish Riksbank will maintain its rate at 1.75%, relying on falling domestic inflation.

A key trigger for the ECB remains negotiations in Islamabad concerning the deblocking of the Strait of Hormuz. If oil transit is not restored, Frankfurt may sacrifice economic growth and raise interest rates more than twice to safeguard price stability in the eurozone.
