Banks may be turning off the cheap credit tap for private equity-led buyouts but that may only give way to a wave of old-fashioned takeovers.

That is the word on the street among corporate financiers and City lawyers, who pointed to yesterday’s agreed $38.1 billion (£18.8 billion) offer by Rio Tinto for Alcan to create a mining and aluminium colossus.

Shares in Hammerson, the property group, had been propped by takeover talk. But those whispers have died down, allowing wider fears in the general market to catch up.
