Currency Stress Index — September 2026: 15.9

The Currency Stress Index reached its monthly peak of 17 on September 1, 2026, and averaged 15.9 for the month. Early in the month, market tension was calmed as the yen surged toward a seven-month high, dropping the index to its lowest point of 15 on September 7. Later on, stress was pushed back up when the Federal Reserve raised interest rates for the first time since 2023 to combat mounting inflation. Overall market tension was also driven by a rising dollar due to a Middle East conflict lifting oil prices. The month ended with additional global news focusing on intensifying Russian hybrid attacks against Europe and a major sanctions dodge involving Chinese goods.
