The Federal Reserve is widely expected to raise its 3.50%-3.75% federal funds target range by a quarter point on Wednesday, potentially making Chair Kevin Warsh's first hike and the central bank's first increase since July 2023. Markets are focused on whether persistent inflation, oil prices above $108 a barrel and rising Treasury term premiums will prompt further tightening, with futures pricing up to four additional increases. The decision and quarterly projections will test the Fed's independence as President Donald Trump continues to demand lower rates, while investors weigh the risk that higher borrowing costs strain housing and other rate-sensitive sectors without slowing stronger parts of the economy. Separately, AI safety warnings and a possible delay of OpenAI's IPO to 2027 pressured technology shares and raised questions about investment in data centers, chips and other AI infrastructure.
