The Bloomberg Dollar Spot Index rose for a fourth consecutive week, gaining nearly 3% this week, marking its longest winning streak since early 2025. Analysts attribute the dollar's strength primarily to surging oil prices, which pressure currencies of energy-importing nations, and persistent global inflation concerns. Brent crude prices jumped on Thursday due to Iran's renewed threats of attacks in the Middle East, which could disrupt energy supplies, prompting investors to flock to the safe-haven dollar.
