Bank capital ratio holds at 18.4 percent under adverse stress test
The Czech National Bank confirmed that the domestic banking sector remains highly resilient to severe economic downturns. Under an adverse scenario covering 2026 to 2028, the capital ratio of tested banks would decline from 20.7 percent to 18.4 percent, remaining far above regulatory minimums.
Buffer against the storm
The supervisory stress test conducted by the Czech National Bank evaluated 13 domestic banks representing around 92 percent of total sector assets.
Based on financial data from the end of 2025, the exercise assessed credit, market, and operational risks over a three-year horizon.
The aggregate consolidated capital ratio stood at 20.7 percent at year-end 2025.
Under the Adverse Scenario, which modeled a severe economic decline across domestic and foreign markets between 2026 and 2028, this ratio dropped to 18.4 percent.
Consequently, the capital buffer of the Czech banking sector remains far above the regulatory minimum requirement even under severe macroeconomic stress.
European standards, local context
The CNB's supervisory stress testing relies on European Banking Authority methodology adapted to the specific conditions of the Czech financial market.
The Baseline Scenario aligns with the central bank's official macroeconomic forecast from its Monetary Policy Report – Winter 2026.
The CNB has partnered with selected banks to perform these supervisory exercises since 2009.
In addition, the central bank has conducted macro-stress tests using internal analytical models since 2004 to monitor broader systemic resilience.
Reassurance without surprises
The test confirms that Czech banks hold impressive capital reserves capable of absorbing severe shocks.
Yet, these predictable results provide little fresh insight into emerging risks facing the sector.
The true challenge for regulators is maintaining vigilance while financial buffers remain high.
