Japan spent 9.79 trillion yen ($62 billion) over the past month to slow the yen’s rapid fall against the U.S. dollar, government data showed Friday, confirming market views that Japanese authorities intervened in the currency market. The amount compares with nearly 9.2 trillion yen Japan spent on multiple yen-buying, dollar-selling operations in 2022. Japanese authorities kept traders guessing whether they had stepped in when the yen suddenly spiked versus the dollar in late April and early May.
