The Japanese yen jumped during Asian trading hours on Monday as traders remained on high alert for potential market intervention by Japanese authorities. This follows last week's suspected actions to curb the yen's decline.
During a holiday-thinned trading session, the yen appreciated by as much as 0.8% against the US dollar, reaching 155.72 yen per dollar, before giving back most of its gains. This sharp movement occurred after Japan potentially utilized approximately 5.4 trillion yen ($34.5 billion) last week to support its currency—a warning signal to traders after the exchange rate breached the 160 yen per dollar level.
David Forrester, a senior strategist at Credit Agricole, noted that it is unclear if these fluctuations reflect another round of intervention, stating that "lower liquidity levels due to the Golden Week holiday can amplify market moves." He added that the 157 level for the dollar-yen pair is significant to watch, as the exchange rate has twice encountered resistance above that level following reported intervention attempts.
On Monday, Japanese Finance Minister Shunichi Suzuki declined to comment on potential currency intervention. Speaking on the sidelines of the Asian Development Bank annual meeting in Uzbekistan, he remarked that speculative trading was observed in the market.
Even as officials avoid questions about recent market movements, attention is turning to Japan's capacity to counter yen weakness. According to analysts at Goldman Sachs Group, Japan possesses sufficient "firepower" to conduct interventions on the scale of last week's about 30 times. However, officials are expected to protect their reserves and act at more opportune moments.
The Wall Street bank added that intervening during a period of relatively mild volatility suggests policymakers view the 160 level as a "defensive red line."
