A group of 25 banks have failed European health checks, while up to 10 of those continue to have a capital shortfall, two people familiar with the matter said on Friday, providing a snapshot of the health of the region’s lenders. The health checks, led by the European Central Bank, found that banks in countries including Greece, Cyprus, Slovenia and Portugal had fallen short of a minimum capital benchmark at the end of last year and that up to 10 remained in difficulty now, the sources said.
