Goldman Sachs: Joint U.S.-Japan Intervention on the Yen Won't Shake the Dollar's Reserve Status
Miles Bennett
Goldman Sachs argues the first joint U.S.–Japan currency intervention in nearly thirty years poses no threat to the dollar's reserve status, calling the market's leap from intervention to reserve-safety concerns an overreaction.
What is the market actually worried about?
Japan is the largest foreign holder of the $31 trillion U.S. Treasury market. Washington stepping in to help Tokyo prop up the yen sparked a specific fear: it might block other nations from selling Treasuries in the future.
This means → if countries start to feel their Treasury holdings are "locked in," the dollar's appeal as a reserve currency shrinks.
Goldman strategist Michael Cahill pushed back directly, calling that inference "quite a leap" and expressing skepticism that the intervention hurts the dollar's reserve role.
Why does Goldman say the dollar is fine?
The key evidence is the Fed's FIMA facility — a mechanism that lets foreign central banks pledge Treasuries as collateral to borrow dollars, without actually selling them.
In plain terms = central banks that need dollars can "borrow against" their Treasuries rather than dump them, creating a liquidity safety net.
Goldman's conclusion: no other currency comes close to the dollar in utility, network effects, and supporting infrastructure. The FIMA facility itself is proof.
Does forced selling actually strengthen the dollar?
Goldman notes that several countries have sold large amounts of Treasuries under market stress to defend their own currencies — and Washington raised no objection. It happened as recently as March this year.
This means → the U.S. stance on selling Treasuries has consistently been open, with no signal of the "you can't sell" constraint the market fears.
Goldman argues these forced sales have actually reinforced the dollar's position over time — each stress test passed deepens trust.
Is Goldman worry-free on the dollar?
Not entirely. The strategists acknowledge that policy uncertainty could pressure the dollar's global role — a core reason Goldman is bearish on the dollar for 2025.
But they see extending that concern to this yen intervention as an overreach.
This reflects Goldman's broader framework: the dollar's long-term risk stems from U.S. policy volatility itself, not from a single coordinated intervention.
How well did the intervention actually work?
This was the first joint U.S.–Japan intervention in nearly thirty years, executed by selling euros for yen — deliberately avoiding a direct hit to the Treasury market.
The U.S. notified the European Central Bank only after the fact, catching Frankfurt off guard.
The effect is already fading: the yen traded at 158.34 per dollar in Friday's Asian session, giving back nearly half of its post-intervention gains. Put simply = the intervention's "medicine" is wearing off, and the yen is sliding back.
