The long-expected credit crunch linked to massive failure in the American sub-prime market really hit home yesterday.

The European Central Bank, regulator of the Eurozone group of countries, piled into the markets with $130 billion of cheap, emergency credit.

The move, the biggest central bank intervention since 9/11, came after reports that commercial lenders were desperately hauling back the supply of loans. The French giant BNP Paribas suspended withdrawals from three of its investment funds because of their exposure to the U.S. sub-prime market, saying “There has been a complete evaporation of liquidity” from credit markets, which could escalate into a worldwide credit squeeze.

Rumours were rife of impending fund meltdowns and banking collapses. Trevor Williams of Lloyds TSB said, “Liquidity has dried up basically. It’s a moment of panic.”

Nick Sparks, risk manager at F&C Partners, said, “People have got caught out. There will be more pain to come.”

You have been warned.
