Enda Curran and Amara OmeokweBloomberg News(TNS)Jerome Powell has two more opportunities to adjust interest rates before his term as Federal Reserve chair ends — and he may not need them. “The window for a cut under a Powell-led Fed is essentially closed,” said Stephanie Roth, chief economist at Wolfe Research. “He is more optimistic about the labor market and economy overall than he was.”The Federal Open Market Committee voted 10-2 Wednesday to hold the benchmark federal funds rate in a range of 3.5%-3.75%. That upgraded assessment of the labor market is likely to hold expectations for a near-term rate cut at bay, despite escalating pressure from the Trump administration. Still, Powell was at pains not to overstate the improvement in the labor market.
