The Treasury is working on contingency plans for the disintegration of the single currency that include capital controls.
The preparations are being made only for a worst-case scenario and would run alongside similar limited capital controls across Europe, imposed to reduce the economic fall-out of a break-up and to ease the transition to new currencies.
Officials fear that if one member state left the euro, investors in both that country and other vulnerable eurozone nations would transfer their funds to safe havens abroad. Capital flight from weak euro nations to the UK would drive up sterling, dealing a devastating blow to the Government’s plans to rebalance the economy towards exports.
