US-Japan FX Intervention Sparks Yen Carry Trade Worries

The US and Japan have intervened in the foreign exchange market to stabilize the yen, but this move has raised concerns about the unwinding of the yen carry trade.

The Korea Institute of Finance (KIF) has warned that if the expectations for a weak yen weaken, it could increase the risk of unwinding the yen carry trade.

This strategy involves borrowing low-interest yen funds to invest in high-interest currency assets, and its success depends on the interest rate differential between the US and Japan, a weak yen, and low market volatility.

The KIF report noted that as the Bank of Japan raised its policy rate to 1% in June, vigilance regarding fundamental changes in the low-interest borrowing environment is increasing.
