This is the best summary I could come up with:

ROME, Aug 8 (Reuters) - Italy dealt a surprise blow to its banks and sent shockwaves across the sector in Europe by setting a one-off 40% tax on profits reaped from higher interest rates, after reprimanding lenders for failing to reward deposits.

Sharply higher official interest rates have yielded record profits for banks, as the cost of loans soared while lenders held off paying more on deposits.

Since then, however, bumper first-half results from banks brought the issue back into focus and prompted the government to act on the eve of the summer political shutdown.

"One has only to look at banks' first-half profits ... to realise that we are not talking about a few millions, but ... of billions," Deputy Prime Minister Matteo Salvini told a news conference in Rome late on Monday.

All main Italian lenders reported much stronger than expected results for the first six months and upgraded their profit outlook thanks to higher rates.

Since rates rose, they have cut current account costs but have refused to reward cash held there saying that money is for day-by-day use and not an investment.
