Established in 1836 as a conservative lender by a group of Belfast merchants, Ulster Bank's linen trade customers continued to thrive even as the island was ravaged by the Famine a decade later. It went on to set up two offices in the Republic in 1860, before merging in 1917 with London County and Westminster Bank, a precursor to NatWest.
Roll on to the end of the century and Royal Bank of Scotland, then under chief executive Fred 'the shred' Goodwin, inherited an exposure to the Celtic Tiger economy in 2000 as part of its takeover of NatWest, before doubling down three years later in Ireland through the purchase here of former building sociey First Active.
With caution thrown to the wind, the bank would bankroll some of the country’s largest developers, including Sean Dunne, and launch the State’s first 100 per cent mortgages
