The recent shift in sentiment on Europe’s bond and equity markets has not eliminated risks in the banking sector. Since 30 October, the index Euro Stoxx Banks has risen by around 5.8 per cent, alongside easing conditions in the bond market. According to CaixaBank Research falling energy prices and signs of talks between the United States and Iran helped bring oil prices down by about 10 per cent and supported share prices. At the same time, a key structural issue remains: Europe’s banks are once again holding more government bonds on their balance sheets.
The European banking supervision notes in its latest risk report that holdings of sovereign bonds classified as highly liquid continued to rise in the first half of 2026. The institutions’ total sovereign exposure stood in the trillions at the end of 2025. This is happening as the Europäische Zentralbank has gradually scaled back its large-scale bond purchases and market forces are once again playing a greater role. The environment is mixed for Spanish institutions: the market recovery is supportive, but the general concentration risks in euro-area countries also apply to banks operating in Spain.
One source of pressure remains France. Budget deficits, rising interest costs and political uncertainty increased risk premiums on French government bonds in autumn 2026. Falling prices for these securities directly affect bank portfolios and can weaken short-term resilience when exposure is high. In its financial stability report, the European Central Bank notes that the close link between governments and banks – often described as a doom loop – becomes more significant again during periods of stress.
Supervisors and central banks draw distinctions: they view it positively that many institutions’ capital ratios and liquidity buffers are now stronger than before the global financial crisis. At the same time, they urge close monitoring of concentration risks, regular stress tests and careful management of maturity and valuation risks in bond holdings. The recent market rally is therefore no reason for complacency. As long as fiscal uncertainty persists in some member states, balance sheets remain more vulnerable to interest-rate and spread shocks – in Spain as elsewhere in the euro area.
For investors and lending practices, this means that the currently calmer market picture reflects an easing of tensions, not an all-clear. The key will be whether highly indebted countries credibly continue on their consolidation path and whether banks diversify their sovereign bond holdings sufficiently to cushion renewed turbulence.
