On July 24, the European Central Bank announced it had begun onboarding foreign central banks into an expanded version of a repo facility called EUREP.
Most investors scrolled past it.
That was a mistake.
Starting in the fourth quarter of 2026, central banks outside the euro area will be able to borrow up to €50 billion in euros on a standing basis, pledging high-quality euro collateral in return.
The facility is open to almost any central bank in the world, barred only for reasons like sanctions or money laundering concerns.
Sounds like plumbing… It's geopolitics.
One of America's most underappreciated advantages has never been its aircraft carriers or its chip factories.
It's the financial architecture built around the dollar. Deep Treasury markets. Global dollar funding networks. Central bank swap lines.
Emergency backstops like the Federal Reserve's FIMA repo facility, which lets foreign monetary authorities repo Treasuries for dollars instead of dumping them into the market during a crisis.
That system feeds itself. Foreign governments need dollars because global finance runs on dollars. Banks hold Treasuries because Treasuries are liquid.
Treasuries stay liquid because regulators treat them favorably. Round and round it goes.
Europe just built its own version of that machine.
Which brings me to the argument I want to make this week. The biggest long-term threat to American financial dominance may not be China selling Treasuries.
It may be America's own allies quietly constructing the infrastructure that makes them less dependent on the dollar system in the first place.
