Yen Gains from Japan's FX Intervention Fall Far Short of Covering Food Tax Cut Gap
Alina Collins
Japan's ruling coalition wants to fund a ¥5 trillion food tax cut with yen earned from FX intervention, but the Finance Ministry's accounting rules make that nearly impossible.
How much does the food tax cut cost?
The Takaichi government plans to slash the food consumption tax from 8% to 1% and distribute roughly ¥60 billion a year to lower-income households.
This means → the government needs about ¥5 trillion (≈$31.7 billion) in replacement revenue or must issue deficit bonds.
Some coalition lawmakers eyed the yen proceeds from FX intervention — but the ledger rules are far more restrictive than they assumed.
Why can't the intervention proceeds be spent directly?
FX intervention funds sit in a Special Account that holds about $1.29 trillion in reserves, mostly U.S. Treasuries.
Selling dollars and buying yen brings yen back, but it does not automatically count as profit: the account books a gain only if the yen is weaker than two months earlier; if the yen has strengthened, the trade records a loss.
In plain terms = most of the yen recovered goes straight to repaying the account's own debt — financing bills (government IOUs) issued when it originally bought dollars. The yen retires those IOUs rather than becoming spendable cash.
How much is actually available?
The Special Account posted a ¥5.06 trillion surplus in FY2025 — seemingly enough — but it has already been carved three ways: ¥1.34 trillion retained in the account, ¥3.13 trillion transferred to the general budget, and roughly ¥800 billion earmarked for defense.
This means → the only unallocated money is a ¥58.5 billion surplus from budget under-estimates — barely 1.2% of the tax-cut gap.
Current rules also require 30% of any surplus to stay in the Special Account. Some lawmakers want to suspend that rule, but even a full suspension would not close the gap.
Are there any other options?
The government is exploring the Fed's FIMA repo facility — a tool that lets foreign central banks pledge U.S. Treasuries as collateral and borrow dollars from the Fed without selling the bonds.
This reflects a dilemma: borrowed dollars carry interest payable to the Fed, which would further shrink the Special Account surplus and leave even less to transfer.
Finance Minister Satsuki Katayama said Monday that authorities "will not hesitate to carry out further joint intervention." But whether intervention proceeds can become usable fiscal resources depends on the combined outcome of account surpluses and Treasury interest income — and the current numbers show the gap is nearly impossible to close.
