Yen Declines Amid US-Iran Uncertainty and Rising Oil Prices

The Japanese yen has been declining against major currencies for four consecutive sessions and is on track to lose value for the third week in August. This trend is attributed to growing uncertainty surrounding negotiations between the US and Iran over the Strait of Hormuz, which is raising concerns about global oil prices and inflationary pressures in Japan.

The yen's decline has caused investors to await further economic data and evidence that could clarify the path of Japanese monetary policy normalization. Market expectations for a 25-basis-point interest rate hike by the Bank of Japan at its September meeting have increased from 70% to 80%, driven by rising global oil prices.

The US dollar index has also been gaining strength, reflecting continued demand for the US currency as a safe haven amid persistent uncertainty over the Strait of Hormuz negotiations. The upcoming US jobs report for July will provide crucial evidence on the likelihood of the Federal Reserve raising interest rates this year.
