The Japanese yen remained a key focus in global FX markets on Monday, with USD/JPY trading near 157 as traders assessed the growing risk of intervention from Tokyo.
The yen was around 156.85 against the dollar after dropping approximately 2% last week, when the currency weakened even after the Bank of Japan delivered another interest-rate increase.
On Friday, the BOJ raised its policy rate to 1.25%, its highest level in 31 years. The decision failed to generate a sustained yen rally, however, as the increase had already been largely priced in and the central bank stopped short of delivering the more hawkish message some traders had expected. Two officials also dissented from the decision.
Intervention speculation intensified after reports suggested Japanese authorities had carried out rate checks. Market participants often interpret these checks as a warning that officials are monitoring excessive currency movements and may be prepared to enter the market directly.
The broader interest-rate environment continues to favour the dollar. Recent tightening from the Federal Reserve has kept U.S. yields elevated, limiting the benefit to the yen from the BOJ’s own rate increase.
Liquidity was also thinner than usual on Monday because Japanese markets were closed for a holiday, leaving USD/JPY particularly sensitive to intervention headlines and shifts in global rate expectations.
For FX traders, the immediate focus remains on whether USD/JPY can stay around the 157 area without triggering stronger action from Japanese authorities.
