The Japanese yen is on track for its biggest weekly loss in about a month, trading at 159.29 per dollar, as traders speculate on the need for Bank of Japan (BOJ) rate hikes to stem its decline.

Despite recent interventions, the yen's value has dropped approximately 0.9% this week, surrendering half the gains made after interventions in late July and early August. The currency's retreat mirrors a similar selloff in May, raising concerns about its stability.

"It's not much of a surprise that the yen has retraced," said OCBC strategist Sim Moh Siong, emphasizing the need for a more hawkish BOJ stance to change the yen's trend.9

The yen's fate now appears tied to the Federal Reserve's policy and expectations of aggressive BOJ rate hikes, especially after a joint operation with the U.S. failed to stabilize the currency.

The BOJ is reportedly considering raising rates as soon as September, with potential for more aggressive hikes, according to sources familiar with policymakers' thinking.

The yen's current position is precarious, hovering near 40-year lows of 164 per dollar before July's intervention, and traders are eyeing the 160 level as a potential trigger for further official action.6

"The onus is on BOJ to step up," Siong added, highlighting the urgency for decisive action to support the yen.
