Fed Repo Facility Lined Up for Japan's Dollar Needs
Posting government paper as collateral overnight raises cash without a sale headline, shielding the long end of the market from official supply during a defense.
Four paragraphs from the Ministry of Finance. The one about the Fed’s repo facility came last.
Camp David, Friday, cabinet meeting. The notepad sitting in front of Scott Bessent had a heading on it reading To Do and under that, in his own hand, Buy Japanese Yen (JPY) $5-10 bil. Reuters ran the photograph that afternoon.
Five to ten billion. Japan had moved something in the region of ¥8.45 trillion two days before that, a figure Bloomberg arrived at by comparing Bank of Japan account movements against money brokers’ forecasts, and Reuters worked the same accounts and got a higher ceiling, $58.97 billion. So, $53bn to $59bn. Nobody actually knows is the honest position here. The ministry publishes intervention totals monthly and in arrears and the July number isn’t out.
Ten months ago Bessent did something structurally similar for Argentina. A $20 billion arrangement with the central bank there, announced October 9, drawing on the Exchange Stabilization Fund, and the Treasury went and bought pesos in the spot market and in the blue-chip swap. Argentina had taken $2.5bn of it by the end of that month. Democrats on House Financial Services wrote to Bessent on the 16th asking for the terms and the terms were never published. I bring it up because it is the same fund and almost nobody mentioned it last week.
Katayama Satsuki’s statement went out Monday morning Tokyo time, 7:30, four paragraphs. The joint action was taken pursuant to the U.S.-Japan Finance Ministers’ Joint Statement issued in September 2025, it said, and countered excessive volatility and disorderly movements in the Japanese yen in recent months. Countered, past tense. The fourth paragraph is the one that got almost no pickup anywhere. Japan also plans to utilize the Federal Reserve’s Foreign and International Monetary Authorities Repo Facility in the future.
FIMA has been sitting there since March 2020, made permanent the following July, and the mechanics are that a foreign central bank posts Treasuries as collateral, takes dollars overnight, then unwinds or rolls it. The securities never get sold. If you are a finance ministry that needs dollars for a currency defence and you very much do not want a headline saying you liquidated US government paper to get them, this is the facility for that, and it matters at the scale Japan works at because Japan was holding $1,191.6 billion of Treasuries in March, down from $1,239.3 billion in February, call it thirteen percent of everything foreigners hold, which is enough to move the long end of a market Bessent has been complaining about in public since roughly February. The rate sits above IORB so it isn’t free money. Japan hasn’t drawn on it. The statement says plans to.
The New York Fed sold euros to buy yen on the Treasury’s behalf, per the FT, and asked at least two US banks to check the yen rate against the euro during the session. Euros, not dollars. I have not been able to establish whether that was a preference or a constraint, the ESF’s euro balance being finite and the Treasury not being in the habit of explaining its reserve management.
Why the yen was where it was. It went through ¥161.97 on June 30, first time since December 1986, and printed 163.24 on July 21. Tokyo had already spent the record on this problem — ¥11.73 trillion across April and May, close to double anything it had attempted before, and the pair was back above the intervention level inside six weeks. Another $20.7 billion went out on July 11. None of it held.
The Takaichi government has mapped ¥370 trillion of combined public and private investment across 17 strategic fields out to fiscal 2040. Semiconductors take ¥68 trillion of that. Physical AI for moving robots takes ¥10.5 trillion, and the government’s own projection is that the AI spending throws off ¥443 trillion in economic impact, a number I would like to see the workings on. There’s a ¥21.3 trillion stimulus package. There’s a proposal to suspend the 8% consumption tax on food for two years. The FY2026 budget: ¥122.3 trillion, with ¥29.6 trillion of new issuance. The criticism, and it isn’t only coming from the opposition, is that the roadmap doesn’t say how projects get picked or where the financing comes from.
Bonds went the same way as the currency rather than the other way. 10-year at 2.830%, a thirty-year high. The 30-year printed a record 3.45% and then came back on reports the ministry would trim super-long issuance. The 40-year went through 4.20% for the first time since that maturity existed, touching 4.24. Yields like that are supposed to bring foreign buying in. Both were being sold at once instead. Capital Economics argued the Liz Truss comparison people kept reaching for is the wrong one and that the yields reflect a new normal for Japan rather than a run.
The board met on the same two days as the intervention and held, 8-1. It had gone to 1% in June, the highest since 1995, still 275bp under the top of the US range. Ueda said at the briefing afterward that hikes at coming meetings were possible without saying one was coming. Bessent had told Fox Business on the Thursday that the yen is very undervalued and that excess volatility is not healthy. Over the weekend he posted that the BOJ has demonstrated a strong commitment to monetary and financial stability and that the two of them continue to enjoy a strong relationship and close coordination. He has been publicly telling the Bank of Japan to raise rates since at least June. He is due to see Ueda at the G20 in Asheville, North Carolina, this month.
Michiyoshi Kato at Sumitomo Mitsui Trust Bank said the market had underestimated the authorities and that another intervention probably takes dollar-yen under 155. At Rakuten Securities, Nobuyasu Atago — who used to be at the BOJ — said Bessent’s influence is significant. Evercore ISI’s Marco Casiraghi and Gang Lyu wrote Friday that without rate differentials behind it the effect of intervention is likely to be relatively short-lived. Atsushi Mimura, who runs currency policy at the ministry, said Japan was getting more than moral support from Washington.
Most of the write-ups called Japan the world’s largest creditor. It hasn’t been since 2024. Net external assets did set a record at the end of 2025, ¥561.75 trillion, eighth straight year up, and Japan still finished third behind Germany at ¥675.5tn and China at ¥636.3tn. Part of that slippage isn’t real: foreign holdings of Japanese equities appreciated ¥62.2 trillion over the year and appreciation on the liability side counts against you. The savings are still out there. Whether normalisation brings any meaningful share of them home is what the JGB market is trying to price and there’s no clean read on it.
The carry unwind risk took up most of the commentary. August 5, 2024 is what everyone points at, the Nikkei down 12.4% in a session.
The yen closed at 157.40 in New York on Friday, the strongest since early May, and got to 155.20 on Monday. Euro to a six-week high of $1.1559 on the back of it, sterling near $1.3476. The Nikkei fell. Asked why the US was doing any of this, Trump said They have a weakening yen, and they wanted a little bit of help. And we’re always there for Japan. South Korea bought won on the Thursday and nobody wrote much about that either. The ministry’s monthly intervention operations release covering this period is due at the end of August, and until it lands the figure for July 30 and 31 stays a reconstruction assembled out of central bank balance sheet residuals.
