The European Central Bank published its May 2025 Financial Stability Review, concluding that the euro area financial system remains resilient but that a sharp rise in geopolitical and policy uncertainty, triggered by US tariff announcements, has materially increased downside risks. It identifies three main channels of vulnerability: disorderly corrections from still-stretched asset valuations amplified by fragilities in non-bank finance, trade tensions translating into corporate and household credit risks for banks and non-banks, and renewed pressures on some sovereigns as weaker growth coincides with higher spending needs. The Review notes that markets sold off sharply after higher-than-expected US import tariffs announced on 2 April 2025 and then rebounded after a 90-day tariff pause for most countries, while remaining highly sensitive to trade-related news. It points to persistent valuation and concentration risks in global equities, corporate bond spreads that appear low relative to elevated uncertainty, and signs that open-ended corporate bond funds may be unprepared for severe liquidity stress. In the non-bank sector, variation margin calls following early-April tariff announcements exceeded EUR 60 billion, equivalent on average to 3.6% of cash buffers for the non-bank financial intermediation sector and 5.4% for pension funds. For banks, profitability stayed strong (return on equity above 9% in 2024) and buffers remained robust (Common Equity Tier 1 ratio of 15.4% and liquidity coverage ratio of 159%), but provisioning needs are expected to rise as macro-financial headwinds and trade uncertainty weigh on the credit outlook. On policy, the Review argues for a comprehensive macroprudential response to non-bank vulnerabilities, including measures addressing liquidity mismatch in open-ended funds, closer monitoring and constraints on leverage, stronger liquidity preparedness for margin and collateral calls, and enhanced EU-wide supervisory coordination to limit arbitrage. It also notes the postponement of the EU application date for the Fundamental Review of the Trading Book to 1 January 2026 and that the European Commission is considering further adjustments to the EU market risk rules to maintain a level playing field, with the ECB indicating it is ready to contribute to consultations.
