Will Fed Chair Kevin Warsh follow the ECB into a new tightening cycle?

The global monetary policy outlook has shifted following the escalation of the Iran conflict and the resulting surge in energy prices. Only a few months ago, investors were expecting many major central banks to continue easing policy in 2026 as inflation pressures gradually faded. Instead, the renewed inflation shock caused by higher oil and gas prices following the Iran war is forcing policymakers to reconsider their stance.

The European Central Bank (ECB) has now become the first major central bank to respond, delivering a 25-basis-point rate hike and signaling that inflation risks have returned to the forefront. Attention is now turning to next week’s Federal Open Market Committee (FOMC) meeting, where markets will get their first policy decision under new Fed Chair Kevin Warsh.

The key question for investors is whether the Federal Reserve will follow the ECB’s lead or choose to remain patient despite mounting inflation pressures.

ECB leads the way as inflation returns to the Eurozone

The ECB raised its three key interest rates by 25 basis points marking its first interest-rate increase since 2023 and bringing an end to the easing cycle that characterized much of 2025.

The move comes as inflationary pressures have intensified across the Eurozone. Headline inflation accelerated to 3.2% in May, its highest level since September 2023, driven largely by a sharp rise in energy costs. Energy prices surged nearly 11% year-over-year as disruptions linked to the Iran conflict created significant supply constraints across global energy markets.

More importantly for policymakers, inflation is no longer confined to energy. Core inflation, which excludes volatile food and energy prices, rose to 2.5% from 2.2% previously, suggesting that higher costs are increasingly spreading throughout the broader economy.

The ECB acknowledged this changing backdrop by revising its inflation forecasts higher. Officials now expect inflation to average around 3% in 2026 before gradually returning toward the central bank’s 2% target over the coming years.

The decision highlights growing concerns that the energy shock could become embedded in wages and consumer prices if left unchecked. Policymakers have been eager to avoid repeating mistakes made during previous inflation cycles when some central banks were criticized for reacting too slowly to rising prices.

However, the ECB’s decision comes at a difficult moment for the Eurozone economy. Higher energy costs are already weighing on economic activity, with the region’s economy contracting by 0.2% during the first quarter of 2026.

The latest ECB projections point to subdued growth, with GDP expected to expand by just 0.8% this year before gradually recovering to 1.2% in 2027. This combination of slowing growth and rising inflation has revived concerns about stagflation, a scenario that presents a particularly difficult challenge for central banks.

Despite these risks, markets interpreted the rate increase as more than a one-off response. Investors are already assigning a meaningful probability to another rate hike later this year, suggesting that the ECB may have initiated a new tightening phase rather than simply delivering a precautionary move.

Will the Federal Reserve follow the ECB?

While inflation concerns are also growing in the United States, the economic backdrop differs significantly from that of Europe.

The U.S. economy has proven more resilient, supported by continued investment in artificial intelligence infrastructure and strong energy exports. Unlike Europe, which is heavily exposed to imported energy costs, the United States has benefited from higher energy production and stronger domestic demand.

Nevertheless, inflation is clearly moving in the wrong direction. Consumer prices rose 4.2% year-over-year in May, marking the third consecutive monthly increase and the highest reading in three years. Although inflation remains well below the peaks seen in 2022, the latest figures reinforce concerns that the Iran-related energy shock is beginning to feed through into the broader economy.

Additional evidence came from producer prices, which rose 6.5% annually in May, their highest level since late 2022. Because producer prices often lead consumer inflation, the data suggests businesses are continuing to face rising input costs that could eventually be passed on to households.

At the same time, the labor market remains surprisingly strong. A series of better-than-expected employment reports has reduced fears of an economic slowdown and strengthened the argument that the Federal Reserve may need to maintain a restrictive stance for longer.

Despite these inflationary developments, markets broadly expect the Fed to leave rates unchanged at next week’s meeting.

One reason is that U.S. rates already stand above those in the Eurozone. Before the ECB’s latest move, European interest rates were close to levels considered neutral for economic activity, giving policymakers greater flexibility to tighten policy without immediately restricting growth.

The Federal Reserve faces a different situation. With rates already at 3.5% to 3.75%, policy is considerably tighter than in Europe. This reduces the urgency for immediate action and gives policymakers more time to assess whether the recent inflation surge proves temporary or develops into a more persistent problem.

Political considerations are also attracting attention. President Donald Trump has repeatedly called for lower interest rates and recently downplayed concerns over rising inflation. Meanwhile, Fed Chair Kevin Warsh has previously expressed support for lower borrowing costs, a stance that aligned him with the White House before taking office.

However, the Fed’s credibility ultimately depends on maintaining price stability. If inflation continues to accelerate while the labor market remains strong, policymakers may find it increasingly difficult to justify a dovish stance.

As a result, next week’s meeting is unlikely to deliver an immediate rate hike, but investors will closely scrutinize the Fed’s projections and forward guidance for clues about future policy.

Conclusion

The ECB has already taken the first step in responding to the inflation shock created by the Iran conflict. Whether the Federal Reserve eventually follows could depend less on politics and more on whether inflation continues to spread beyond energy and into the broader U.S. economy.

For now, the most likely outcome is a pause accompanied by a more hawkish tone. But if inflation and producer prices continue to surprise to the upside in the months ahead, discussions about rate hikes rather than rate cuts may quickly become the dominant theme for U.S. monetary policy.
