Currency Stress Index — August 2026: 16.3

The Currency Stress Index reached its lowest point of the month at 15 on August 6, helped by a firmer yen following a landmark intervention and a weaker dollar driven by optimism over Iran talks. However, tensions rose the following day after news surfaced about how the U.S.-Japan intervention might reshape global currency markets. Pressure spiked to a monthly high of 18 on August 19 when headlines revealed that many Fed officials believe higher interest rates will be needed if inflation remains elevated. Across the entire month, the index averaged a score of 16.3.
