With the data pipeline clogged, attention shifts to Friday's core CPI, expected to hold steady at 3.1% — potentially the Federal Reserve's only clear inflation signal ahead of its policy meeting next week. Markets have already priced in a 25-basis-point rate cut, with traders betting the Fed will ease again in December. Meanwhile, a Reuters report said the Trump administration was weighing sweeping curbs on high-tech exports to China — from laptops to jet engines — in retaliation for Beijing's latest restrictions on rare earth shipments. The report pushed markets lower on Wednesday, injecting fresh uncertainty. Reporting by Pranav Kashyap in Bengaluru; Editing by Shilpi Majumdar
