European central banks walked a tightrope Thursday, navigating the fallout from the ongoing conflict in the Middle East as they announced their latest interest rate decisions. The war in Iran, which began in late February, has injected significant uncertainty into the economic outlook, threatening energy supplies and pushing up inflationary pressures across the continent. While most banks opted to hold rates steady, the shadow of geopolitical risk loomed large over their statements, signaling a potential shift in monetary policy in the coming months.
The decisions from the European Central Bank (ECB), Bank of England (BOE), Sweden’s Riksbank, and Swiss National Bank reflect a delicate balancing act: acknowledging the rising risks to economic stability while avoiding moves that could further destabilize already fragile markets. Prior to the outbreak of hostilities, a more benign inflation outlook had suggested a period of stable or even falling interest rates. That outlook has now been fundamentally altered, forcing policymakers to reassess their strategies.
The Swiss National Bank (SNB) was the first to announce its decision, maintaining its main policy rate at 0.00%. Though, the SNB likewise signaled a heightened willingness to intervene in foreign exchange markets to counter any “rapid and excessive appreciation of the Swiss franc, which would jeopardize price stability in Switzerland,” according to a statement released Thursday. The bank acknowledged that the war has rendered the economic outlook “considerably more uncertain,” anticipating that rising energy prices will contribute to higher inflation in the short term and potentially leisurely global economic growth.
Sweden’s Riksbank also opted to hold its main policy rate steady at 1.75%, stating that the rate is “expected to remain at this level for some time to approach.” However, the bank cautioned that the war in Iran warranted “vigilance,” and that it would monitor developments closely, prepared to adjust monetary policy if necessary. Despite the uncertainty, the Riksbank noted that fundamentally favorable conditions remain for economic recovery in Sweden, although underlying inflation has been unexpectedly low recently. The bank anticipates the conflict will dampen growth in the near term and push up CPIF inflation due to higher energy prices.
ECB Navigates Geopolitical Headwinds
Even before the escalation of tensions in the Middle East, the European Central Bank was not anticipated to alter its benchmark interest rate, with Eurozone inflation remaining close to the central bank’s 2% target. Recent data from Eurostat showed inflation in the Eurozone rose to 1.9% in February, up from 1.7% in January. However, the war’s potential to disrupt energy markets has complicated the picture.
ECB President Christine Lagarde had previously described the Eurozone’s economic outlook as “in a solid place,” but also warned against complacency. That caution now appears prescient. Traders are closely watching for guidance from the ECB on how it might respond to potential disruptions to oil and gas supplies, particularly if Iran were to close the Strait of Hormuz. Konstantin Veit, portfolio manager at PIMCO, expects the ECB to “stress heightened geopolitical uncertainty and signal a more hawkish tone rather than move policy immediately,” anticipating a short-term inflation overshoot peaking around 3% this year, with energy contributing roughly 1 percentage point.
Bank of England Holds Firm Amidst Uncertainty
The Bank of England also maintained its current course, holding its key interest rate, known as ‘Bank Rate,’ at 3.75%. A rate cut had been widely expected at the March meeting, aimed at easing pressure on households and businesses grappling with high borrowing costs. However, the unfolding situation in Iran has significantly diminished the likelihood of an imminent cut.

Economists now believe the Monetary Policy Committee (MPC) will err on the side of caution, awaiting greater clarity on the duration and impact of the conflict. “The Bank of England is unlikely to surprise this week,” said John Wyn Evans, head of Market Analysis at Rathbones. “Rate cuts once seen as plausible for spring have been fully priced out, and a rise later in the year can’t be dismissed.” The prevailing sentiment is that the central bank will adopt a “holding pattern,” avoiding both tightening and loosening of monetary policy until the situation becomes clearer.
The decisions by these central banks underscore the complex challenges facing policymakers in a world increasingly shaped by geopolitical instability. While the immediate impact of the war in Iran remains uncertain, its potential to disrupt energy markets and fuel inflation has forced a reassessment of economic forecasts and monetary policy strategies across Europe.
Looking ahead, the next key data point will be the release of updated economic projections from the ECB, which will provide further insight into the bank’s assessment of the risks and its likely policy response. Market participants will be scrutinizing these projections for any indication of a shift towards a more hawkish stance.
