Tuesday: Dollar Reaches a One-Week High
Tuesday’s 21.07.2026 Asian currency trading was marked by caution. Most regional currencies remained confined to narrow trading ranges, unwilling to make a decisive move in either direction. Investors faced a difficult choice: on the one hand, the escalating conflict in the Middle East was pushing the dollar higher as a safe-haven currency; on the other, hopes for a diplomatic resolution prevented it from strengthening too sharply.

However, the most alarming development occurred on another front. The Iran-backed Houthi movement in Yemen announced a naval blockade of Saudi Arabia. This means that energy supplies passing through the Red Sea and the Bab el-Mandeb Strait could be disrupted....
