London, 29 September 2026 — EBM Newsdesk Analysis — By Amr Shabana
On Monday, 28 September, ECB President Christine Lagarde told European lawmakers the central bank will expand the safety nets that let foreign central banks borrow euros. She said future swap lines would reflect the need for “a sovereign euro area and a strong euro”. Behind the move is a quiet fear in central banks and markets that the Federal Reserve could one day cut its own swap lines, which support trillions of dollars in foreign loans. The ECB is not saying the Fed will pull the plug. It is making sure Europe is not caught out if it does.
This is the plumbing of global finance, and it matters more than it sounds. Businesses around the world borrow in dollars because they know the Fed will provide dollars in a crisis. If Europe wants companies in Warsaw, Istanbul or Cape Town to borrow, trade and save in euros, it has to offer the same promise. That means the ECB acting as lender of last resort far beyond the eurozone’s borders. The timing is not accidental either. Central banks have been cooling on US debt for months, and Frankfurt wants the euro positioned to benefit.
What a swap line actually does
A swap line is simple. Two central banks swap currencies for a set period. A foreign central bank hands over its own money and receives euros, which it can then lend to its local banks during a panic.

SubscribeThat does two jobs. It eases pressure on foreign borrowers who owe euros. It also stops a crisis abroad from spilling back into the eurozone through fire sales and defaults.
The ECB also runs a second tool, known as repo, which lets foreign central banks borrow euros against euro-denominated collateral. Nearly 30 central banks have applied to use it. Repo is safer for the ECB but slower in a crisis, because borrowers must already hold approved assets and accept a discount on their value.
A small network for a big currency
At present the ECB’s own swap agreements are thin. Its main arrangements are with the Fed and the central banks of Canada, the UK, Switzerland and Japan. Beijing, by contrast, has used more than 40 bilateral swap deals to push the renminbi abroad.
Choosing who gets access is a political decision. Emergency access to a currency shapes where companies borrow and which governments owe you a favour. The dollar’s reach was built this way, and the euro has never seriously tried to compete. Even now, when markets panic, safe-haven flows still run towards the dollar.
The harder problem
Swap lines defend demand for euros during stress. They do not create it. Investors want a deep pool of safe assets to hold, and the eurozone still offers a patchwork of national bonds rather than one market the size of US Treasuries. A true global euro needs an integrated capital market, closer fiscal union and a permanent supply of joint Eurobonds, as analysts at IAI argue.
That is where the ECB runs out of road. Frankfurt can build the safety net. Only national governments can agree to borrow together.
The ECB also has a full inbox. It is fighting eurozone inflation driven by the energy shock, and Lagarde herself is expected to leave before her term ends in 2027. Whoever succeeds her will inherit this project half-built.
What I Think
Lagarde is right to move now, while the dollar looks less dependable than it has for decades. Better swap lines are cheap insurance, and they make euro borrowing more attractive at the margin. But nobody should confuse this with the euro becoming a rival to the dollar. That depends on Berlin, Paris and The Hague agreeing to a common safe asset, and they have resisted it for 25 years. The ECB has done its part. The capitals have not.
