On June 30th, the USD/JPY touched the 145 level, marking the first time since mid-November last year and approaching the lowest level since the Japanese government intervened. Speculation in the market suggests that the Japanese government may intervene again to support the yen.
Here is a timeline of the Japanese government's intervention in the foreign exchange market last year:
September 8, 2022: The USD/JPY breaks through 144, prompting a joint meeting of the Japanese Ministry of Finance, the central bank, and the financial department.
September 14: The USD/JPY approaches 145, and the Bank of Japan implements a rate check, requiring major Japanese commercial banks to provide details of their foreign exchange transactions to the central bank.
Subsequently, on September 22, the Japanese government and the central bank conducted an intervention totaling 2.8 trillion yen but failed to prevent the yen from further depreciation.
After the USD/JPY breaking the 150 level, the Japanese authorities conducted additional interventions amounting to 6.35 trillion yen on October 21st and 24th. As a result of the weakening US dollar, the yen started to appreciate.

Referring to last year's intervention process, which involves "government authorities joint meeting → exchange rate review → foreign exchange intervention," the joint meeting of government authorities has already taken place at the end of May. The market is concerned about whether the exchange rate review will be implemented in the future.
According to analysts at JPMorgan Chase, the underlying fundamentals behind the depreciation of the yen suggest that there is further room for it to decline. The Federal Reserve is still aggressively raising interest rates while the Bank of Japan maintains its accommodative monetary policy. Yujiro Goto, a foreign exchange strategist at Nomura Securities, stated that although the magnitude and speed of the yen's decline may not be sufficient to trigger government intervention, the possibility of such a scenario "clearly increases."
Mitrade Analyst:
According to the statements, Japanese authorities have a high tolerance for yen depreciation. The yen may depreciate to around 150 before undergoing exchange rate review, and intervention would likely occur if it depreciates beyond 150.
In the short term, the divergence in monetary policies between the US and Japan persists, suggesting continued weakness in the yen. However, in the long term, there is potential for a yen rebound due to the possibility of the Bank of Japan adjusting its Yield Curve Control (YCC) policy in the second half of this year.
From a technical perspective, the USD/JPY has retreated within a 2% range of the 20-day moving average, with resistance at 145. The RSI indicator indicates overbought conditions, implying a potential further decline in the USD/JPY in the short term, with support seen at 141.8.
