- Tokyo authorities deployed 11.7 trillion yen ($72.25 billion) during April and May to prop up the currency with limited success.

On Tuesday, the Japanese yen tumbled to a four-decade low versus the U.S. dollar. The greenback surged to 162.41 yen during trading before moderating to approximately 162.15.
This decline represents the currency’s weakest performance since 1986. The sharp deterioration has sparked speculation about potential government intervention to stabilize the yen.
Forces Behind the Dollar’s Ascent
The primary factor pressuring the yen is growing market conviction that U.S. interest rates will climb higher. American inflation continues running above the Federal Reserve’s preferred level.
During the latest Federal Reserve policy gathering this month, nine out of nineteen officials indicated they anticipate at least one rate increase before year-end. This hawkish pivot has accelerated capital flows into the dollar.
According to Lee Hardman, senior currency analyst at MUFG Bank, the Federal Reserve might overlook the recent uptick in inflation data. Still, he emphasized that no definitive evidence suggests policymakers will soften their stance on tightening monetary policy.
Market participants are now focused on Thursday’s employment figures from the United States. Disappointing job growth could alter investor sentiment regarding the Fed’s upcoming policy decisions.
Tokyo’s Currency Defense Efforts
The Japanese currency has now declined for four consecutive quarters, representing its most prolonged downturn in four years. This quarter alone, the yen is headed for a 2% depreciation.
Government officials in Japan allocated 11.7 trillion yen—equivalent to roughly $72.25 billion—during the spring months attempting to shore up the currency. While these measures temporarily strengthened the yen, the improvement proved fleeting.
Hardman suggested that the unsuccessful spring intervention might prompt Japanese authorities to exercise greater restraint before acting again. He noted that policymakers may accept a softer yen provided the depreciation remains controlled and orderly.
Finance Minister Satsuki Katayama reiterated Japan’s willingness to take action when necessary. However, her statements lacked the forceful rhetoric typically associated with imminent market intervention.
An important distinction from the spring situation is that the yen’s current weakness is predominantly against the dollar. The euro, by contrast, was changing hands at 184.97 yen—elevated by historical measures but still beneath the April peak of 187.95.
Broader Currency Market Weakness
The U.S. dollar index, measuring the greenback against a basket of six major currencies, stood at 101.32. The index is poised for a 1.4% quarterly advance, following a 1.6% increase during the opening quarter.
The euro dropped 0.24% to $1.1396, hovering near the one-year trough reached last week. Softer-than-anticipated inflation readings from France and select German regions intensified downward pressure on the common currency this week.
The European Central Bank implemented a rate hike earlier in June, and financial markets anticipate another increase before December. That outlook could shift if price pressures moderate or economic activity deteriorates significantly.
Sterling declined 0.2% to $1.3234. Currencies of commodity-exporting nations also faced headwinds as energy prices retreated.
The Norwegian crown fell to its lowest level against the dollar in six months. Canada’s currency traded near a 14-month trough, while Australia’s dollar slipped to a three-month low of $0.6867.
As Tuesday’s session concluded, the dollar maintained its position near the 40-year peak against the yen, with market observers anticipating Thursday’s U.S. employment report for additional guidance.
