Top Greek banks would lose 15.5 billion euros in stress scenario
The health check by the European Central Bank, aimed at uncovering any capital shortage before Athens exits its 86 billion-euro ($106 billion) bailout in August, was carried out separately from a stress test of other euro zone banks.
Test results for 33 lenders from other euro zone countries will be published in early November.
The ECB's stress test of Greece's four largest banks - Piraeus, NBG, Eurobank and Alpha - was done early to allow time for any possible capital shortfall to be filled before Athens leaves its bailout.
Among the banks, Alpha Bank performed best as its Common Equity Tier 1 ratio (CET1) would drop by 8.56 percentage points to 9.69 percent according the adverse scenario of the test.
It would drop by 8.68 percentage points to 6.75 percent for Eurobank, 9.56 percentage points to 6.92 percent for National Bank of Greece and 8.95 percentage points to 5.90 percent for Piraeus Bank.
According to the ECB, the 2018 health check was not a pass or fail exercise as no predetermined capital threshold was set that would trigger a need to recapitalise. ■
