The article explores how the size of a country's banking sector affects its financial stability. It looks at 38 countries and finds that having a large or small banking sector doesn't guarantee stability. Even big banks can face problems, like in Ireland, while small banks can also be vulnerable, like in Greece. The study uses different indicators to measure the risk in each country's banking system. Overall, the relationship between banking size and stability is not straightforward, and both big and small banks can face challenges during a financial crisis.
