In its Green Paper, the Treasury is seeking the views of the financial industry on "whether new statutory powers should be sought to assist in promoting order in the financial system in extreme circumstances".
Such circumstances would include "problems arising from physical causes, such as a terrorist attack or severe adverse weather, or from IT difficulties, such as a computer bug or virus".
The Treasury has put forward two new powers: suspension and direction. It claims that such powers would only be used in extreme circumstances and not in "a purely financial crisis".
Suspension powers would, according to the document, allow the Government to "suspend certain financial system obligations" and freeze markets for a certain period of time.
The direction powers would enable the Government to take direct control of certain financial infrastructures "including exchanges, clearing houses and payment systems".
According to the consultation document, companies could not be sued for non-payment while markets were suspended.
The Treasury is looking for opinions "on whether such legislation would be justified by the nature and scale of the threat". The consultation also invites comments on "additional ways in which the financial authorities could usefully assist the private sector's work in making financial markets more resilient".
Financial Secretary, Ruth Kelly, said:
"The 11 September attacks on the United States caused terrible loss of life and physical damage. They also showed the problems that physical disruption on such a scale brings for the financial system – as exemplified by the four-day closure of the New York Stock Exchange.
"Financial services play a vital role in the UK economy. This makes it particularly important to be sure that we have good arrangements in place to maintain the financial system's resilience during major operational disruption".
