Dollar Index Jumps 0.75% in Biggest One-Day Gain in Five Months

A 0.75% single-day move in the dollar index is a meaningful repricing for a market that usually grinds in small increments, and the fact that it came as a steady intraday climb rather than a spike suggests broad, sustained demand rather than a single headline. For dollar-sensitive assets — commodities, emerging-market currencies and crypto among them — this is the kind of move that tightens global liquidity conditions and pressures valuations priced in dollars. The open question is whether this is a one-session adjustment or the start of a firmer trend; the weekly gain was far more modest than Friday's move, so follow-through in the sessions ahead is what matters.
