Global flashpoints and US inflation data keep markets on edge

Global markets are navigating a volatile mix of geopolitical flashpoints and a crucial U.S. inflation report that could determine the Federal Reserve's next move. The Houthi attack on an Egyptian vessel in the Red Sea, a fresh North Korean ballistic missile test, and China's planned naval drills near Taiwan have all added to the risk backdrop.

Brent crude prices have climbed for a sixth consecutive session, marking the longest winning streak since late April. This sustained rise in energy costs is intensifying pressure on central banks as they grapple with inflation, complicating their policy decisions.

The focus on Wednesday is firmly on the U.S. consumer price index (CPI) data. Economists expect prices to have risen 0.1% in July, a rebound from a 0.4% decline in June. On an annual basis, inflation is forecast to have slowed to 3.4% from 3.5%. The report follows a disappointing U.S. payrolls figure last week, highlighting the delicate balance the Fed must strike between supporting economic growth and curbing price pressures.

Market expectations are split, with money markets pricing in an even chance of a rate hike at the Fed's September meeting. The outcome will heavily influence currency markets. The yen has weakened to 159.45 per dollar, its lowest level since coordinated intervention by Japan and the U.S. last week had strengthened it to around 155.2.

Meanwhile, the Reserve Bank of Australia delivered a hawkish hold on interest rates, and traders are increasingly betting that the Bank of Japan could tighten policy as soon as next month. European stock futures pointed to a slightly lower open, with contracts for the Euro Stoxx 50, DAX, and FTSE all trading marginally in the red. U.S. futures, however, showed slight gains.
