Central Banks Gear Up for Simultaneous Rate Decisions Amid Global Market Volatility

The global foreign exchange market saw significant shifts last week as inflation persistence and central bank tightening expectations took center stage. In the US, August's Consumer Price Index (CPI) remained steady at 3.4% year-over-year, but core CPI rose by 0.3% month-over-month, exceeding expectations and indicating a stall in disinflationary trends.

This led to increased market expectations of a September Federal Reserve rate hike, jumping to around 86%, with U.S. Treasury yields reaching nearly three-year highs and the dollar index strengthening in the short term.

In Europe, the European Central Bank raised interest rates by 25 basis points to 2.5% for the second time this year, with a hawkish stance limiting the euro's downside. The Japanese yen appreciated roughly 4% over the month amid strong market bets that the Bank of Japan will hike rates to 1.25% this week.

This week marks 'Super Central Bank Week' with the US, UK, and Japanese central banks set to announce policy decisions in quick succession. Coupled with geopolitical tensions in the Strait of Hormuz, investors should remain vigilant for sharp market swings as multiple factors converge.
