There's that D-word again!

From the Telegraph: Britain on the brink of an economic depression, say experts.

Families must brace themselves for a slump of far greater severity and longevity than the recessions of the 1980s and 1990s, they warned. They said the current crisis will be of a scale to rival the biggest peace-time crisis in modern history — the Great Depression.

The warning was delivered by economists and politicians after the Office for National Statistics revealed that the economy shrank by 1.5 per cent in the final three months of 2008 alone.

The contraction follows a 0.6 per cent fall in gross domestic product (GDP) — the most comprehensive measure of Britain’s wealth generation — during the previous three months. This means Britain fulfils the criteria for a technical recession — two successive quarters of negative output.

The news sent the pound sliding to its lowest level since 1985. Sterling dropped more than three quarters of a cent to $1.3688 as investors speculated that the Bank of England may be forced to cut interest rates towards zero in response to the recession.

Britain is likely to suffer more than other economies due to its heavy reliance on the financial services sector, which has all but imploded in the wake of the economic crisis, experts said.

Others raised the spectre of an outright economic depression, often defined by experts as a peak-to-trough economic contraction of 10 per cent. Aside from the demobilisation periods following the First and Second World Wars, this kind of contraction has never taken place — not even in the 1930s’ Great Depression.

Roger Bootle, the managing director of Capital Economics, said: "I think there’s a very good chance this recession will be the worst since the 1930s. I suspect the economy could shrink by 6 per cent from last year to the end of next year — and that might not be the end.

The plight facing Britain is uncannily similar to the 1930s, since prices of many assets —from shares to house prices — are falling at record rates, but the value of the debt against which they are held remains unchanged.

Albert Edwards, a strategist at Société Générale, likened the British economy to a Ponzi scheme — a fraudulent debt mountain like that allegedly used by the New York hedge fund manager Bernard Madoff.

“What I find amazing is that people aren’t really nailing Gordon Brown and [Bank of England Governor] Mervyn King for this,” he said. “At least in the US they had the excuse of the arrival of sub-prime — a new sector of the market. We didn’t really have anything similar but we ended up with a bigger national Ponzi scheme than the US.”
