ECB poised for first rate rise of 2026 as ministers push stalled capital markets union

Frankfurt and Luxembourg will host two of the most consequential gatherings on the European economic calendar this week, each carrying implications that stretch well beyond the immediate decisions on the table. On Thursday the European Central Bank's governing council meets in Frankfurt with financial markets all but certain it will raise the deposit facility rate from 2.00% to 2.25%, the first increase since the tightening cycle was paused in April. Two days later, finance ministers convene in Luxembourg for the Eurogroup and the Economic and Financial Affairs Council, where the stalled project to create a genuine capital markets union faces its most serious test in years.

Why the ECB is moving now

The bank kept rates unchanged at its April meeting, signalling confidence that the disinflationary trend of late 2025 was becoming entrenched. Headline inflation in the euro area had fallen to 1.8% in March, below the 2% target, and core inflation was edging down. That picture has shifted. Energy markets have been roiled since the escalation of the Iran conflict in late April, pushing Brent crude above $95 a barrel and European gas futures to levels not seen since the winter of 2022-23. The ECB's own staff projections, updated in March, assumed an average oil price of $82 for 2026. That assumption now looks obsolete.

Christine Lagarde, the ECB president, acknowledged as much in a speech to the European Parliament's economic affairs committee last month. "The longer the war continues and the longer energy prices remain high, the stronger is the likely impact on broader inflation and the economy," she said. "We are certainly moving away from the baseline." The phrasing was deliberate. By admitting the baseline had shifted, Lagarde prepared markets for a policy response without committing to a predetermined path. Money markets now price a 95% probability of a 25 basis-point move on Thursday, with the terminal rate for this cycle seen around 2.75%.

The energy shock and its transmission

The inflationary mechanics of an oil and gas shock are familiar but the context has changed. In 2022 the ECB was criticised for reacting too slowly to the post-invasion energy spike. This time the bank is determined not to be caught behind the curve. The risk, however, is that monetary tightening feeds into an economy that is already showing signs of fatigue. Euro area GDP grew just 0.1% in the first quarter of 2026, with Germany contracting for a second consecutive quarter. Manufacturing PMIs have been below the 50 threshold since November. A rate increase now tightens financial conditions for firms and households at the very moment external demand is softening.

The governing council will also publish updated staff macroeconomic projections on Thursday. Those forecasts will incorporate the higher energy price path and likely show inflation averaging above 2% through 2027, even with the projected rate rises. That projection alone would justify a move in the eyes of the hawks on the council, notably the governors of the Bundesbank and the Dutch and Austrian central banks. The doves, led by the French, Italian and Spanish governors, will argue that the energy shock is a supply-side phenomenon that interest rates cannot fix and that premature tightening risks choking the recovery.

Capital markets union: a decade of drift

While the ECB deliberates, a parallel conversation in Luxembourg will determine whether the EU's longest-running financial integration project finally gains traction. The capital markets union was launched with fanfare in 2015 by the Juncker Commission, promising to diversify funding away from bank lending, deepen cross-border investment and make the euro area more resilient to asymmetric shocks. Eleven years later, the scorecard is thin. Cross-border equity holdings within the EU have risen only modestly. Securitisation markets remain a fraction of their US counterparts. Venture capital is still overwhelmingly national. The single biggest obstacle has been the refusal of member states to cede supervisory power to a European authority.

The current framework relies on the European Securities and Markets Authority (ESMA) coordinating national competent authorities. ESMA has direct supervision only over credit rating agencies, trade repositories and certain securitisation vehicles. For everything else, market infrastructure, investment firms, prospectus approval, the 27 national supervisors retain primacy. That fragmentation creates regulatory arbitrage, duplicative compliance costs and, critics argue, a supervisory culture that protects domestic champions. The Commission's 2024 CMU action plan identified centralised supervision as the "essential enabler" for deeper integration. It went nowhere in the Council.

The six-country coalition changes the arithmetic

What makes this week different is the agreement reached by the six largest EU economies, Germany, France, Italy, Poland, Spain and the Netherlands, to push aggressively for centralised supervision. Together they represent roughly 70% of the EU's population and an even larger share of its financial assets. The joint position, finalised in May after months of quiet diplomacy, calls for ESMA to be granted direct supervisory powers over significant market infrastructure operators, large investment firms and cross-border fund managers. It also proposes a European regime for insolvency law to replace the patchwork of national frameworks that makes cross-border restructuring prohibitively complex.

The significance lies not only in the weight of the signatories but in the inclusion of Poland. Warsaw has historically been sceptical of financial integration that could marginalise its developing markets. Its participation signals a calculation that the benefits of a deeper single market, access to deeper liquidity, lower cost of capital for Polish firms, outweigh the sovereignty costs. For Germany and France, the agreement papers over persistent differences. Berlin has long favoured a model where ESMA supervises only the largest entities while national authorities retain day-to-day oversight. Paris has pushed for a more federal approach with a European supervisor that has teeth. The compromise text fudges the definition of "significant" and leaves the threshold for direct supervision to be determined in technical negotiations.

Von der Leyen's coalition of the willing

The six-country push is also a response to pressure from the top of the Commission. At an informal European Council in February, Ursula von der Leyen issued an unusually blunt ultimatum. "Get me right. I prefer doing this by 27," she told heads of state and government. "But the option exists for at least nine member states, if they want to move forward faster." The reference was to enhanced cooperation, the Treaty mechanism that allows a minimum of nine member states to proceed with deeper integration in a policy area where unanimity cannot be reached. It has been used for the financial transaction tax, the European Public Prosecutor's Office and the unitary patent. Applying it to capital markets supervision would be unprecedented in scope.

Von der Leyen's threat serves two purposes. It concentrates minds in the Council by raising the prospect of a two-speed financial union where the most integrated markets set the rules for everyone else. And it gives the six-country coalition leverage: if the remaining 21 member states block progress, the coalition can credibly threaten to activate enhanced cooperation. The political risk for the holdouts, typically smaller member states with large financial sectors relative to their economies, such as Luxembourg, Ireland and Malta, is that they end up subject to rules they had no hand in writing.

What the ministers must decide this week

The Eurogroup on Thursday and the ECOFIN council on Friday will not produce a final legal text. The legislative process for amending the ESMA regulation and creating a European insolvency framework requires Commission proposals, Parliament approval and Council agreement under qualified majority voting. What ministers can do is give a political mandate to the Commission to draft legislative proposals by the autumn, with a view to adoption before the end of the current parliamentary term in 2027. They can also agree on the principles that will guide those proposals: the scope of direct supervision, the funding model for an expanded ESMA, the governance safeguards for non-participating member states, and the relationship between the European supervisor and the national authorities that will lose powers.

A further complication is the European Parliament. The economic affairs committee has its own vision for CMU, generally more ambitious on supervision and more insistent on consumer protection and sustainability standards. The rapporteur for the ESMA review, a German MEP from the Greens/EFA group, has already signalled that Parliament will push for direct supervision of all crypto-asset service providers and a mandatory European single access point for financial data. Negotiations between Council and Parliament on the 2024 ESMA review took 18 months. There is no reason to expect the next round to be faster.

The political constraints that could still derail progress

Even with the six-country agreement, the path to a functioning capital markets union remains littered with veto points. Tax treatment of cross-border investments remains a national competence requiring unanimity. The withholding tax directive, the parent-subsidiary directive and the interest and royalties directive all create friction that no amount of supervisory integration can resolve. The Commission's 2025 proposal for a European safe asset, a synthetic security backed by a portfolio of sovereign bonds, went nowhere because Germany and the Netherlands refused to mutualise even synthetic risk. Without a safe asset, European banks and insurers lack a truly euro-area-wide risk-free benchmark, keeping funding markets fragmented.

There is also the question of the UK. London remains the dominant centre for euro-denominated derivatives clearing, foreign exchange trading and asset management. The EU's equivalence decisions for UK clearing houses expire in June 2027. If the capital markets union creates a European supervisory regime that UK firms cannot easily access, the risk of further fragmentation rises. The Commission has been quietly preparing contingency plans for a "no equivalence" scenario, but the political cost of cutting off European firms from London's liquidity pools is enormous. This week's meetings will barely touch on the UK question, but it looms over every discussion of European financial autonomy.

For now, the two tracks, monetary policy in Frankfurt, financial architecture in Luxembourg, proceed in parallel. They are connected by the same underlying reality: the euro area remains a monetary union without a fiscal union, a banking union without a common deposit insurance scheme, and a capital markets union that exists mainly in PowerPoint slides. This week will not solve any of those contradictions. But it will show whether the institutions and the largest member states have the political will to stop managing them and start fixing them.
