The main lenders have put away at least 4.5 billion euros ($4.8 billion) in response to the measure, or 2.5 times what the government would have pocketed from the tax.

Italy in August announced a surprise 40% tax on banks' net interest margin (NIM), later giving lenders the option to boost reserves by an amount equivalent to two-and-a-half times the tax.

Below is a table summarising what the main banks have disclosed regarding the tax when reporting third-quarter earnings.

All figures in millions of euros.
