Japan's Currency Jumps 5% Against the Dollar in One Week

Japan's yen rose nearly 5% against the dollar in the week through September 8, 2026 — a seven-month high. Reuters reports traders expect Japan's central bank to raise interest rates again soon, betting 68% on a September increase. The bank lifted rates to 1.0% in June from 0.5%. A 5% weekly jump in a major currency is rare.
