Sticky inflation, uncertainty around the Federal Reserve's policy path, and a sharp pullback in technology stocks shaped global market sentiment this week, while renewed attacks on Gulf shipping routes pushed energy prices to their highest levels in five months. The US Dollar Index ended the week at 101.77, down 0.4 percent, after briefly touching an 18-month high of 102.9. September CPI data showed headline inflation accelerating to 3.7 percent year-on-year from 3.4 percent, driven by higher energy costs, while core inflation rose 0.3 percent month-on-month against expectations of 0.2 percent.
