WASHINGTON — The world's most influential central banks signaled a significant shift in monetary policy strategy on Friday, indicating that interest rates will likely remain elevated for longer than previously expected as they grapple with stubbornly persistent inflationary pressures.

In coordinated statements that caught some market participants by surprise, the Federal Reserve, European Central Bank, and Bank of England all emphasized their commitment to price stability, while acknowledging that the final stages of bringing inflation back to target levels may prove more challenging than anticipated.

"The last mile is always the hardest," Federal Reserve Chair Jerome Powell said in remarks prepared for delivery at a monetary policy conference. "We remain committed to our 2 percent inflation target, and we will maintain a restrictive policy stance for as long as necessary to achieve that goal."

The Fed's updated economic projections, released alongside the statement, showed policymakers now expect only two rate cuts in 2026, down from the four cuts projected in December. The benchmark federal funds rate is expected to end the year at 4.75 to 5 percent, significantly higher than the 4.25 to 4.5 percent anticipated just three months ago.

Markets reacted sharply to the hawkish pivot, with the S&P 500 falling 1.8 percent and the Nasdaq Composite dropping 2.3 percent. The 10-year Treasury yield rose to 4.52 percent, its highest level since November, as traders repriced expectations for the path of short-term interest rates.

"The Fed is clearly worried about a resurgence in inflation," said Mohamed El-Erian, chief economic adviser at Allianz. "They're willing to accept slower growth and potentially higher unemployment to ensure that inflation doesn't become entrenched."

ECB President Christine Lagarde echoed similar concerns in Frankfurt, noting that services inflation in the eurozone has proven "remarkably sticky" despite substantial progress in reducing overall price pressures. The ECB left its key deposit rate unchanged at 3.5 percent and suggested that rate cuts remain unlikely before the fall.

The shift in central bank rhetoric comes amid growing evidence that the global economy has proved more resilient to higher interest rates than many economists predicted. Labor markets remain tight in most developed economies, with unemployment rates near historic lows despite months of monetary tightening.

"Central banks are caught in a difficult position," explained Janet Henry, global chief economist at HSBC. "On one hand, growth has held up better than expected. On the other, that resilience has made it harder to bring inflation fully under control."

Some analysts warned that prolonged high interest rates could eventually trigger a sharper economic slowdown, particularly if they expose vulnerabilities in sectors that have become heavily leveraged during the era of cheap money. Commercial real estate and private credit markets are seen as particularly vulnerable.

Looking ahead, central bankers emphasized that policy decisions will continue to be data-dependent, with close attention paid to incoming inflation figures and signs of cooling in labor markets. The next major test will come with the release of February employment data next week.
