"The ECB continues to believe that financial stability is not part of its core business. As its outgoing president, Jean-Claude Trichet, put it, the ECB has “only one needle on [its] compass, and that is inflation.” The ECB’s refusal to be a lender of last resort forced the creation of a surrogate institution, the European Financial Stability Facility. But everyone in the financial markets knows that the EFSF has insufficient firepower to undertake that task – and that it has an unworkable governance structure to boot.
Perhaps the most astonishing thing about the ECB’s monochromatic price-stability mission and utter disregard for financial stability – much less for the welfare of the workers and businesses that make up the economy – is its radical departure from the central-banking tradition. Modern central banking got its start in the collapse of the British canal boom of the early 1820’s. During the financial crisis and recession of 1825-1826, a central bank – the Bank of England – intervened in the interest of financial stability as the irrational exuberance of the boom turned into the remorseful pessimism of the bust."
