Ireland’s S&P 500 index will tumble on Monday after the Irish government said it would delay a planned decision on whether to slash capital gains taxes to 20% from 30%.

Ireland’s biggest bank, TDOC, said on Friday it would stop investing in the sector, citing uncertainty over the tax cuts and its concerns about the impact of Brexit on the country.

The Irish government has also been accused of failing to follow through on plans to raise corporate taxes.
