WSJ: Japan spent a record $50 billion in one day to defend the yen, data confirms

The data confirms Tokyo will spend heavily, and alongside Washington, to defend the yen. That keeps intervention risk firmly in play as USD/JPY trades near 158, well within reach of this year’s low near 164. It caps the upside for dollar-yen and makes long positions more two-way, including Morgan Stanley’s carry-driven long USD/JPY call. Rate expectations remain the dominant driver, though: around 80% odds of a December Fed hike are keeping the gap wide, while a December BOJ move, supported by Ueda’s upside-inflation comments, is the main path to narrowing it. Expect officials’ rhetoric to sharpen if the pair approaches 160 again.---Japan’s record intervention numbers show how hard Tokyo, with Washington’s help, fought the yen’s slide, and how little lasting difference it made while the US-Japan rate gap stays wide.Summary:Japan spent a record $50 billion, almost 8 trillion yen, in a single day on July 30 to support the yen.Total intervention across July and August was around 15.4 trillion yen, roughly $97 billion, exceeding April and May.Finance Minister Katayama and US Treasury Secretary Bessent confirmed joint intervention in late July, the first since 1998.The yen had hit a four-decade low near 164 per dollar earlier this year and still trades around 158.Expectations of further Fed hikes are keeping the US-Japan rate gap wide.The BOJ raised rates to 1.25% in September and is expected to move again by year-end.Japan spent a record $50 billion in a single day to support the yen in late July, official data released on Monday showed. The figures confirm the scale of an intervention campaign that markets had long suspected and that included rare coordinated action with the United States.Ministry of Finance figures showed Tokyo bought a total of around 15.4 trillion yen, roughly $97 billion, across July and August, the Wall Street Journal (gated) reported. Almost 8 trillion yen of that was deployed on July 30 alone, the largest one-day intervention on record. The total for the two months exceeded the amount spent in April and May.The figures are not a surprise in themselves, since the operations were widely flagged at the time, but they put hard numbers on how forcefully Tokyo moved. Finance Minister Satsuki Katayama and US Treasury Secretary Scott Bessent confirmed in late July that the two countries had intervened jointly to support the yen, the first coordinated operation of its kind since 1998.The scale reflects mounting alarm in Tokyo after the yen slid to a four-decade low near 164 per dollar earlier this year. Bessent was outspoken about the currency’s decline over the summer. He backed Japan’s efforts to counter what he described as its undervaluation and pointed to the role a weak yen was playing in pushing up domestic inflation.Yet the data also highlight the limits of intervention. The yen initially strengthened after the joint action, but it is still trading around 158 per dollar. Rising expectations of further Federal Reserve rate hikes have reinforced the view that the wide interest rate gap between the US and Japan will persist, keeping pressure on the currency.Bessent’s comments also fed speculation about faster tightening by the Bank of Japan. The BOJ raised rates to 1.25% in September and is expected to move again before the end of the year, having cited yen weakness as a key factor shaping its economic and inflation outlook. Governor Kazuo Ueda said on Friday that he sees some upside risks to inflation as energy costs feed through to consumer prices.For traders, the message is that Tokyo has shown it is willing to spend heavily, and alongside Washington, to defend the yen. The currency’s direction, though, still depends largely on the gap between US and Japanese interest rates.  This article was written by Eamonn Sheridan at investinglive.com.
