Yen Slides Ahead of Pivotal Japanese Election

The Japanese yen is on course for its largest weekly decline since October, with the currency weakening for four consecutive days. Traders are driving the sell-off ahead of this weekend’s election, betting on a decisive victory for Prime Minister Sanae Takaichi's Liberal Democratic Party.

On Thursday, the yen approached the 157 level against the U.S. dollar as investors anticipate a strong electoral mandate will empower Takaichi to implement expansive fiscal policies, putting further downward pressure on the currency.

Hedge Funds Bet on Renewed Weakness

In response to the political outlook, hedge funds are re-establishing positions that profit from a falling yen. The currency's slide brings it closer to levels that have previously triggered government intervention in the foreign exchange markets.

Market analysts are closely watching the 160 mark as the next major threshold.

"Assuming a strong Takaichi majority on the February 8th election, a return to max risk premium would imply USDJPY at 160," noted Namik Immelbäck, chief strategist at Skandinaviska Enskilda Banken AB. He suggested that an intervention could follow a sharp move toward that level, pointing to a potential opportunity for authorities.

"Should USDJPY have a sharp reaction and test 160 one can probably expect intervention, and conveniently Wednesday February 11th is a holiday in Japan which offers less liquid markets and an opportune moment to intervene," Immelbäck added.

Intervention History and Official Statements

The yen saw a brief period of strength last month following speculation about rate checks by the Federal Reserve Bank of New York. However, those gains were quickly erased after U.S. Treasury Secretary Scott Bessent stated that the United States is "absolutely not" intervening in the currency market.

Adding to the bearish sentiment, Prime Minister Takaichi recently commented that a weak currency can present a significant opportunity for the nation's export industries. This remark has reinforced market expectations for policies that favor a softer yen.
