The FSA stressed Britain was at the forefront of developing this market both on the high street with retail products and in the capital markets with the growth of Islamic-compliant bonds or sukuk, which are structured to pay investors profits from an underlying business rather than interest.

What seems increasingly clear is that the combination of generous government guarantees with rampant profit-making in inadequately capitalised institutions is an accident waiting to happen – again and again and again. Either the banking industry should be treated as a utility, with regulated returns, or it should be viewed as a profit-seeking industry that operates in accordance with the laws of the market, including, if necessary, mass bankruptcies.

There is a second reason that the hands-off approach has been shown to be wanting. During the past few years, a significant part of liquidity and credit creation has occurred outside the banking system. Hedge funds and special conduits have been borrowing short and lending long and, as a result, have created credit and liquidity on a massive scale. As long as this liquidity creation was not affecting banks, it was not a source of concern for the central bank. However, banks were heavily implicated. Thus, the central bank was implicitly extending its liquidity insurance to institutions outside the regulatory framework. It is unreasonable for a central bank to insure activities of agents over which it has no super­vision, just as it would be unreasonable for an insurance company selling fire insurance not to check whether the insured persons take sufficient precautions against the outbreak of fire.
