Renewed tensions between the US and Iran have driven oil prices up and reignited concerns about global inflation, according to FX Street (OCBC). Markets are now fully pricing in the possibility of a Federal Reserve interest rate hike by October, increasing uncertainty among investors.

The Euro has declined against the US Dollar for a second consecutive day on Wednesday, pressured by risk aversion linked to the Middle East situation and growing expectations of Fed tightening, FX Street reported. This has pushed the Euro down to two-week lows as investors seek safer assets.

For Japanese investors, these developments underline the importance of monitoring geopolitical risks and Federal Reserve policy moves, which continue to influence FX markets and commodity prices critical to Japan's economy.
