The European Central Bank has begun onboarding non-euro-area central banks to its enhanced EUREP repo facility. For the first time, the non-euro world has a standing euro liquidity backstop. Currencies internationalise through exactly this kind of quiet lender-of-last-resort plumbing, and the first test of appetite comes with drawings from the fourth quarter.

For most of the world’s central banks, access to euros in a crisis has been a favour: negotiated line by line, time-limited, renewable at the Eurosystem’s discretion. As of last week it is a standing service. On 24 July the European Central Bank (ECB) began onboarding non-euro-area central banks to its enhanced repo facility, known as EUREP, with first drawings possible in the fourth quarter of 2026. Markets did not move. That was the intention. Reserve managers from Warsaw to Jakarta will have read the announcement closely all the same, because it changes what holding euros means on the day funding dries up.
What Changed on 24 July
The terms, set out in the ECB’s press release of 24 July 2026 and a guideline adopted on 15 July, contain no surprises. Onboarded central banks will borrow euros against high-quality euro-denominated collateral, priced at the main refinancing operations (MRO) rate plus a spread which, the ECB says, is set to preserve the backstop character of the facility. The maximum line size is EUR 50 billion per central bank. Transactions run from one day to one week, extendable, and drawn funds can be used flexibly, without ex ante restrictions.
Five national central banks, the Deutsche Bundesbank, the Banco de Espana, the Banque de France, the Banca d’Italia and De Nederlandsche Bank, will operate the facility under ECB coordination. Access is, in the ECB’s wording, “in principle open to all central banks and monetary authorities outside the euro area”, unless excluded on money-laundering, terrorist-financing or sanctions grounds. Usage will be visible: the ECB will publish the total daily amount of liquidity provided under EUREP and its swap lines every week.
The Temporary Facility That Stayed
Created in June 2020 as a temporary pandemic backstop, EUREP served, as analysts at ING noted in February 2026, eight non-euro-area European central banks, Hungary’s and Romania’s among them. The ECB prolonged it after Russia’s full-scale invasion of Ukraine, then folded it into a permanent liquidity-lines framework in January 2024. In a blog post of 29 January 2024, board members Piero Cipollone, Philip Lane and Isabel Schnabel drew the operative lesson from those years: “the mere existence of a liquidity line pre-empts financial tensions from materialising.”
The decision of 14 February 2026 turned that lesson into architecture. Christine Lagarde, the ECB’s president, announced the expansion at the Munich Security Conference that day and framed it as insurance for a fragmenting world. She was explicit about the second-order intent: “The availability of a lender of last resort for central banks worldwide boosts confidence to invest, borrow and trade in euros, knowing that access will be there during market disruptions.”
A Backstop Creates Its Own Demand
A reserve manager deciding whether to hold euro-denominated bonds is pricing a tail risk: in a crisis, can those bonds be turned into cash without selling them into a falling market? A standing repo line answers that question in advance. It also creates its own demand. The insurance works only for institutions that already hold eligible collateral, so EUREP requires euro sovereign paper on the balance sheet before the storm, and the incentive to accumulate it operates in calm times, which is precisely when reserve allocations are decided. This is how a currency internationalises.
The academic groundwork is established. The Bank for International Settlements hosted much of the post-2008 debate on an international lender of last resort, and research by Saleem Bahaj and Ricardo Reis, published in the Review of Economic Studies in 2022, found that central-bank liquidity lines put a ceiling on offshore funding costs and encourage lending in the currency that provides them. The ECB is, in effect, buying that documented effect for the euro.
Measured Against the Fed
Set EUREP beside the Federal Reserve and the comparison cuts both ways. The Fed’s closest equivalent is the Foreign and International Monetary Authorities (FIMA) repo facility, made standing in July 2021 against Treasuries held in custody in New York; per the Fed’s announcement of 28 July 2021, its terms were a rate set initially at 25 basis points and a per-counterparty limit of USD 60 billion. The more generous instrument, the Fed’s unlimited standing swap lines, has been reserved since October 2013 for five partners: the central banks of Canada, the United Kingdom, Japan, Switzerland and the euro area itself.
EUREP sits in FIMA’s category, collateralised and priced as a backstop. Its declared openness, though, gives the euro something the dollar system offers only selectively: liquidity insurance that does not require membership of a club. ING’s Chris Turner, Benjamin Schroeder and Dmitry Dolgin observe that EUREP “now looks akin to” FIMA, and read the expansion as a step towards a global euro.
Three Grounds for Scepticism
Start with the number that is missing. The spread over the MRO rate has not been published, and it will determine whether EUREP reads as usable insurance or as an emergency-only signal. Punitive terms breed stigma, and stigma has hollowed out backstops before. Uptake is the second unknown, and it stays unknowable until drawings begin in the fourth quarter; the predecessor facility gives little guidance, since ING describes usage since 2020 as modest and sporadic. A backstop that goes undrawn may be quietly succeeding, or invisibly failing, and the weekly data alone will not distinguish the two.
The last caution is the biggest: this is no challenge to the dollar, and claiming otherwise misreads the design. The ECB’s own report on the international role of the euro, published in June 2026, puts the euro at roughly 20 per cent of global foreign exchange reserves against approximately 57 per cent for the dollar. A facility priced above market rates, lending only against collateral the borrower must already own, is built for the moment euro assets would otherwise be dumped. The defensible claim is narrower. EUREP removes one specific reason not to hold euros; it supplies no reason to hold them.
Watch the Queue, the Spread and the Weekly Data
The first tell is the onboarding queue, and specifically whether the early names are familiar European neighbours rolling over existing arrangements or monetary authorities in Asia, the Gulf and Latin America, where dollar dependence is most actively debated. The spread matters too, once published: near FIMA’s pricing, or notably above it. From the fourth quarter, watch the ECB’s weekly liquidity publication, where even zero drawings alongside a lengthening list of onboarded central banks would be evidence the insurance is valued. Reserve managers have a concrete task in the meantime: establish whether existing euro holdings meet EUREP’s collateral criteria, and what onboarding requires, before conditions make the question urgent.
Unglamorous by Design
None of this is glamorous, and it is not meant to be. The ECB has built the euro a piece of infrastructure the currency has lacked for its entire existence: a standing, priced, global promise of liquidity against good collateral. It holds for central banks and monetary authorities with high-quality euro-denominated assets that sit outside sanctions and money-laundering exclusions, and it does nothing for commercial banks, for jurisdictions with no euro assets to pledge, or for anyone seeking euros unsecured. Whether it shifts reserve behaviour may not be clear before the next crisis. Backstops are judged on the day they are needed. This one, at least, will exist.
