The yen is back under pressure, with USD/JPY trading above 159 and moving closer to the closely watched 160 level.
Less than two weeks after Japan and the U.S. carried out a rare coordinated currency intervention, the yen has already given back around half of its gains.
The problem is that intervention has not changed the main force behind the move: the wide gap between U.S. and Japanese interest rates.
The 10-year U.S. Treasury yield is around 4.69%, compared with about 2.85% for Japan’s 10-year government bond, keeping demand for higher-yielding U.S. assets strong.
That makes the yen carry trade attractive again. Investors can still borrow yen at relatively low costs and move money into higher-yielding markets.
160 Is Back in Focus

The 160 level has become an important line for traders.
A rapid move above 160 could increase expectations of another intervention, particularly if yen weakness becomes disorderly.
But intervention alone may not be enough to create a lasting yen recovery.
Markets are now looking toward the Bank of Japan’s September meeting, with traders pricing in roughly a 50%–60% chance of a 25-basis-point rate hike.
For USD/JPY traders, the setup is becoming increasingly sensitive: another push toward 160 could bring intervention risk back into focus, while a stronger BOJ tightening signal could give the yen room to recover.
