Yen Gains as Katayama Signals Rising Intervention Risk
The yen became stronger against the dollar on Friday.
It gained after Japan’s finance minister discussed concerns about its weakness.
She said US President Donald Trump also shared those concerns.
She said Japan would keep working with US Treasury Secretary Scott Bessent.
These comments made traders more careful about betting that the yen will fall.
Traders think Japan might buy yen if it weakens too much.
The yen has faced pressure because US interest rates may stay higher than Japanese rates.
Uncertainty about future Bank of Japan rate increases has also hurt the yen.
Japan and the United States previously worked together to buy yen when it fell beyond 160 per dollar.
The yen rose as much as 0.6% to 157.95 per dollar on Friday.
Finance Minister Satsuki Katayama said Donald Trump shared concerns about yen weakness.
Katayama said she would continue coordinating with US Treasury Secretary Scott Bessent.
Traders are increasingly alert to possible Japanese intervention near the 160-per-dollar level.
Renewed Federal Reserve rate expectations and uncertainty over Bank of Japan tightening continue to pressure the yen.
