Global equity markets fell on September 28, 2026, as the Reserve Bank of Australia raised its policy rate to 4.6%. The move coincided with a surge in 10-year U.S. Treasury yields to a 19-year high, pressuring major indices.
Why it matters
The Australian rate hike, prompted by inflationary pressure from energy prices and business costs, contributed to global market jitters alongside rising bond yields. These combined factors increase the cost of borrowing for households and businesses, complicating the global economic outlook.
The Reserve Bank of Australia lifted its policy rate to 4.6%, the fourth such increase in 2026. Simultaneously, the Dow Jones fell 0.67% as 10-year U.S. Treasury yields reached their highest level in 19 years.
