As Gordon Brown heads for Washington to try to convince Barack Obama to create a “global regulatory system” the new administration should ask itself why listen to a man who failed so conspicuously for 12 years.

In Britain, Brown has come in for stern criticism in recent days for his failure to stop the immense and growing disaster occurring in the British economy.

Lord Turner, new head of the Financial Services Authority (FSA), blames Brown when Chancellor for the failure of regulation which led to catastrophic losses at Northern Rock, HBOS and RBS.

“They existed within a political philosophy where all the pressure on the FSA was not to say ‘why aren’t you looking at these business models?’, but ‘why are you being so heavy and intrusive, can’t you make your regulation a bit more light touch?’,” he said.

“We were supervising people like HBOS within a particular philosophy of the way you do regulation, which I think in retrospect was wrong. I think (the FSA’s actions were) a competent execution of a style of regulation and a philosophy in regulation which was, in retrospect, mistaken.”

Similarly, Bank of England Governor Mervyn King claims he has been shouting warnings for years about risky lending without any response from Brown.

It is on the record that Brown delivered a speech in the City urging them to take even greater risks.

The Prime Minister is now trying to cover up the mess by throwing the kitchen sink at sacked RBS boss Fred Goodwin’s enormous pension. Significantly this was done as the Treasury unveiled its third bank bailout in the form of a £325 billion insurance scheme for desperate RBS.

Meanwhile the head of the Audit Commission, Steve Bundred, warned that public debt is at “Armageddon levels” and will exceed two-thirds of the entire annual economic output of the country.

It’s a simple proposition. Assets prices are falling so fast, no financier can back them until a loan against them is guaranteed against loss.

What that means is that asset prices have to find a floor. Only then will the real economy find willing partners in the financial economy and finance start to flow.

The question is, when will that happen?

The answer is, no-one knows.

Guesstimates vary from the ridiculously optimistic — the British Treasury forecast — to the ridiculously pessimistic — “never”.

In between, the more realistic: “2012″.

From there we may see a slow growth back to financial and economic health, but it will need a sea-change in regulation and business administration. In particular we need to create bulkheads against the madness of globalized swings that can disrupt the strongest of economies. As David Brook wrote in the New York Times:

“We’re living in an age when a vast excess of capital sloshes around the world fueling cycles of bubble and bust. When the capital floods into a sector or economy, it washes away sober business practices, and habits of discipline and self-denial. Then the money managers panic and it sloshes out, punishing the just and unjust alike.”

As the BBC’s Business Editor, Robert Peston points out: “If you combine consumer, corporate and public sector debt [in the UK], the ratio of our borrowings to our annual economic output is a bit over 300 per cent, or more than £4,000 billion [six trillion dollars].”

Those numbers make even 2012 seem optimistic.

The only safe answer is, “Rebuilding starts when there are no more cliffs to fall off.”
