The European Central Bank bought its last net tranche of eurozone government bonds in July 2022. What followed was, in some respects, an orderly handover: private investors stepped in, yields adjusted, and the mechanical shock of the ECB’s withdrawal was absorbed without the crisis many had feared. Yet the long-run consequences of that exit are still propagating through the architecture of European capital markets. By the first quarter of 2025, the Eurosystem held just 25% of all euro-area sovereign bonds — down from a peak of 33% as recently as late 2022. The gap the ECB left behind has to be filled by someone else. Increasingly, eurozone issuers are deciding to go and find those buyers directly, on their terms, in their currencies.

A Structural Shift, Not a Tactical Detour

The push into non-euro issuance isn’t happening in isolation. It unfolds against a backdrop of seismic, slow-moving change in who owns fixed-income assets globally. The OECD’s Global Debt Report 2026 puts the combined government and corporate bond market at roughly $78 trillion, with euro-area issuers accounting for 34% of that total — split almost evenly between sovereign and corporate paper. Within that vast pool, the composition of buyers has shifted decisively. Central banks, the dominant marginal purchaser of the past decade, have retreated. In the euro area specifically, the Eurosystem’s quantitative tightening since mid-2022 has compelled the private sector to absorb an estimated €430 billion of German government bonds alone — a recalibration with no peacetime precedent.

Layered on top is a geopolitical repricing. The ECB’s Financial Stability Review for November 2025 noted that euro-area non-bank financial institutions still carry heavy concentrations in US dollar assets, even as investors globally began rotating away from US Treasuries following Washington’s tariff turbulence earlier that year. That asymmetry — of European savings lodged in dollar assets while European borrowers need to attract dollar investors — defines the precise opportunity that multi-currency issuance is designed to exploit.

1 — The Anatomy of Eurozone Non-Euro Bond Issuance

Eurozone non-euro bond issuance has accelerated sharply across the sovereign, financial, and corporate segments throughout 2025. Eleven European borrowers — among them Orange SA, CaixaBank SA, and Raiffeisen Bank International AG — raised an aggregate $20.45 billion in US dollar-denominated offerings through early November 2025, according to Akin Gump’s annual bond market review. That figure captures only named issuers in the senior unsecured segment; it excludes covered bonds, AT1 capital instruments, and private placements, which tell a similar story. These are not crisis-driven deals priced out of necessity. They’re strategic, roadshow-backed transactions designed to cultivate investors who don’t naturally trade in euros.

The pull factors are equally important as the push. Across the wider emerging-market universe — a useful benchmark for global appetite shifts — EM sovereign issuance reached nearly $200 billion in the first nine months of 2025, the highest level for that period on record, with nearly half of new hard-currency bonds denominated in non-dollar currencies. Euro-denominated emerging-market bonds reached 30% of new issuance on a trailing 12-month basis, up from around half that share two years earlier. Eurozone issuers are, in a sense, rowing into a current that’s already moving.

The mechanics behind the trade are straightforward. Investors who hold mandates anchored to US dollars or sterling face real friction when trying to acquire a German corporate bond priced in euros — they must take on currency risk or arrange their own hedges. By issuing in dollars or sterling, the eurozone borrower eliminates that friction, bringing the bond to the investor rather than waiting for the investor to come to the bond. The European Stability Mechanism recognized this logic as early as 2017, when it established its US dollar issuance programme for precisely this reason: access to a wider investor base whose mandates wouldn’t otherwise reach euro-denominated paper.

Cross-currency economics are, for now, highly accommodating. A Reuters analysis from February 2025 found that companies converting dollar interest payments into euro payments through cross-currency swaps could shave nearly 200 basis points off their all-in funding costs. That differential reflects the gap between ECB and Federal Reserve rate trajectories: the ECB has eased steadily while the Fed held, generating a basis that eurozone borrowers can effectively arbitrage.

2 — The Structural Logic: Why Are Eurozone Issuers Issuing Bonds in US Dollars?

European borrowers are turning to dollar, sterling, and yen debt primarily to access investors whose mandates limit or preclude direct holdings of euro-denominated paper. With the ECB’s Eurosystem reduced from 33% to 25% of euro sovereign outstanding since 2022, issuers face a structurally wider distribution task. By offering bonds in dollars or sterling, they bring the credit to where those investors already operate — expanding the buyer pool without requiring cross-currency hedging on the investor’s side.

The structural interpretation cuts deeper than opportunistic arbitrage. During the decade of ECB quantitative easing, foreign investors’ share of euro-area sovereign bonds fell from around 37% in 2015 to just 21% by mid-2022, as the Eurosystem crowded them out. That contraction wasn’t benign. It represents a generation of US pension funds, UK insurers, and Asian sovereign wealth vehicles that drifted away from European credit during the years of sub-zero yields — and that now need to be structurally accommodated, not merely re-invited.

The post-QE investor landscape is qualitatively different from its predecessor. The OECD’s analysis documents a clear shift toward more price-sensitive private-sector investors as central banks withdraw, and warns explicitly that yields may need to remain structurally higher to sustain demand from those investors in countries where fiscal trajectories appear stretched. That warning has particular force for higher-debt eurozone sovereigns — and it’s why, even from Rome or Lisbon, the logic of non-euro issuance as a demand-cultivation tool is increasingly worth entertaining.

Yet there’s a complicating wrinkle. The same geopolitical disruptions driving investors globally to reassess US asset concentrations are also creating natural demand for euro-denominated paper. Since April 2025, net purchases of euro-area government bonds by international investors have been consistently strong. In that single month, foreign investors bought €26 billion in euro-area government bonds while simultaneously selling €56 billion of US Treasuries. If euro bonds are already in demand, why issue in dollars?

The picture is more complicated than the aggregate flows suggest. That foreign buying is heavily concentrated in German, French, Italian, and Spanish sovereign benchmarks — securities that trade on screens globally and require no proprietary infrastructure to settle. European bank capital instruments, sub-investment-grade corporate credit, and mid-tier sovereign names still struggle to clear the screens of US fund managers who don’t routinely run euro-denominated book exposure. Multi-currency issuance solves precisely that problem.

3 — Implications and Second-Order Effects

The consequences extend well beyond the bond desk. If eurozone issuers successfully cultivate a durable non-euro investor base, they reduce their structural dependence on any single policy regime — specifically, whether the ECB resumes asset purchases during the next downturn. That’s a form of funding sovereignty that finance ministers and corporate treasurers alike have good reason to value.

The ESM’s December 2025 market commentary put this directly: cumulative euro-denominated issuance outside the euro area exceeded €1 trillion in 2025, with countries including China, Chile, Indonesia, and Saudi Arabia choosing the euro for their sovereign bonds. “Diversification is the name of the game,” the ESM wrote. “These issuers want to open new horizons and tap new investors.” The logic applies with equal force in reverse — eurozone borrowers issuing in dollar and sterling are playing the same game, from the other side of the currency table.

Still, multi-currency issuance creates new vulnerabilities. A eurozone corporate that issues in dollars takes on foreign-currency liability exposure. If the hedge is imperfect, or if cross-currency swap markets seize up during a stress episode — as they did, briefly, in March 2020 — the mismatch can become damaging quickly. Raiffeisen Bank International, one of the eleven European borrowers that tapped the dollar market in 2025, operates in a complex regulatory environment across Eastern and Central Europe; its dollar issuance adds funding flexibility, but also another dimension of currency risk management that its euro-only peers don’t carry. Verizon, going the other direction, closed a £1 billion sterling note alongside a €2.25 billion Eurobond in November 2025 — a dual-tranche structure that captures two demand pools but multiplies hedging complexity on both sides.

For the ECB, the implications are subtler but real. A eurozone bond market reliant on globally dispersed, price-sensitive private investors will structurally exhibit more volatility than one where a single policy-driven buyer dominated the clearing mechanism. The ECB’s Financial Stability Review warned that “sudden reversals of holdings — in response to global economic or political shocks — could have destabilising effects on sovereign bond markets.” Cultivating non-euro investors diversifies demand; it also multiplies the number of actors who might exit simultaneously under stress. That’s a trade-off central bankers in Frankfurt understand, and that weighs on how aggressively they welcome the trend in official communications.

The OECD’s analysis reinforces this concern. It notes that structural shifts away from defined-benefit to defined-contribution pension arrangements are reducing institutional demand for long-duration sovereign bonds more broadly, regardless of currency denomination. Issuer flexibility may be rising while structural anchor demand is falling — a combination that pushes funding costs higher over the medium term, in both euros and in any other currency eurozone borrowers choose.

4 — The Counterargument: Is Non-Euro Issuance Actually Necessary?

Not everyone is persuaded that the non-euro turn is strategically necessary, sustainable, or wise for European issuers to pursue at scale.

The alternative view is grounded in supply and demand data that looks, from the euro side, genuinely encouraging. Euro-denominated corporate bonds now exceed €3.2 trillion in outstanding value across more than 3,700 issuers, according to Bloomberg data cited by BNY in September 2025. In 2025, euro corporate bond funds attracted net inflows of €19.2 billion, making the category one of fixed income’s best-performing segments. That’s not a market starved of buyers. The spread compression throughout the year — peripheral sovereign spreads tightening, investment-grade credit trading tight — tells the same story: money is flowing into euro assets, not out of them.

From an execution standpoint, dollar or sterling issuance adds real complexity. US Securities and Exchange Commission registration requirements for publicly offered dollar bonds generate significant legal cost and disclosure burden. Smaller eurozone issuers — particularly those below investment-grade or without established international investor relations programmes — may find that the incremental demand from dollar investors doesn’t justify those costs. A single-currency, well-syndicated euro deal can still clear effectively when the credit is familiar and the roadshow thorough.

There is also a longer structural concern. The same geopolitical fragmentation driving non-euro issuance today could, in a different scenario, make dollar-denominated European bonds harder to place. The OECD warns explicitly that “geopolitical tensions can have an outsized impact on demand from foreign investors” and describes global financial fragmentation risk as “an important concern for issuers.” A eurozone bank that builds a structural dollar investor base assumes that US investors will remain willing and able counterparties through whatever political environment follows. That assumption deserves scrutiny.

The New Normal in European Debt Markets

The eurozone’s search for new investors — in new currencies — is, fundamentally, a reckoning with a decade of monetary exceptionalism. When the ECB was buying everything, issuers didn’t need to think hard about who else might want their bonds, or in what form. Now they do.

What’s striking is the convergence at work. As global investors reassess US assets and rotate toward Europe, European borrowers are simultaneously rotating into dollar and sterling markets to capture investors before they fully discover the euro denominated product on offer. It’s a two-way traffic jam at a major intersection — everyone crossing in opposite directions, each convinced they’re moving toward better returns.

Whether the non-euro turn by eurozone issuers proves durable will depend on how long the interest-rate differential between the US and the eurozone persists, and on whether the geopolitical triggers driving investor rotation toward European assets moderate or intensify. Either way, the market infrastructure — the legal frameworks, the dealer networks, the hedging conventions — is being built now.

The ECB’s exit from bond markets was always going to force a renegotiation of who funds Europe. That renegotiation is visibly underway. It turns out the terms are written, in part, in other people’s currencies.
