A version of this article appeared in Syntagma recently.

As we predicted here, this credit crunch cum downturn cum recession cum slump cum … was always going to happen in slow motion. That’s because of the normal lags involved in the transfer of economic conditions between countries and continents. Britian is said to be around nine months to a year behind America.

While the U.S. downturn started at the back end of last summer, it’s only now starting to decimate the British economy and parts of the eurozone. If we want to know how bad it’s going to get, we only need to peer across the Pond.

Gold rushes come and go in the world’s innovation capital, California. But when they go … they really go.

The City of Vallejo in California has filed for Chapter 9 bankruptcy, making history it seems. Half Moon Bay, home to some internet digerati, may well be next. According to John Moorlach, Orange County board chief, “This is the tip of the iceberg: everybody is going to line up for Chapter 9 in California.”

What can it mean to people on the ground when their city goes belly up? What of their assets, houses etcetera? It will be interesting to watch this pan out.

According to Goldman Sachs and Lehman Brothers American house prices are likely to fall 25pc from peak to trough. With between 10m and 12m households in negative equity already, there’s still a way to go.

Shares across the developed world are set for big falls too. Albert Edward Société Générale’s global strategist says, “Nowhere and nothing will be immune. We are on the cusp of an equity meltdown that will slash and shred portfolios. We see a global recession unfolding. Liquidity will drain away and crush the twin emerging market and commodity bubbles. The recent hope that ‘the worst might be over’ is truly staggering. Profits are disintegrating.”

Ambrose Evans Pritchard of the Telegraph (UK) — ever the Cassandra (rightly so, in my view) — says pointedly, “Britain, Europe, Japan, and China will go down before America comes back up. This is turning into a synchronised bust, after all. The Global Slump of 2008-09 is under way.”

The Bank of England and the European Central Bank are still stubbornly refusing to cut rates because of inflation fears, which will be the least of our miseries in the next two years and should abate soon as global demand falls off the much-imagined cliff.

It’s probably true that Ben Bernanke’s Federal Reserve has saved the U.S. and other countries from another Great Depression. But nothing can stop a slump now because it’s already happening.

In Britain a recession is defined as two consecutive quarters of negative growth.

It’s said that this definition was deliberately put about by advisers to President Johnson in the 1960s to allow him wriggle room when events were not neat and symmetrical — which is the the most likely case.

For example, if within a six-month period one month bucks the trend and shows a slight positive number, it can’t be a recession no matter how bad conditions are across the economy.

However, we know that because of population and productivity growth, the UK needs to expand by about 2pc just to keep unemployment from rising.

We should forget the official definition because even flat growth is negative for the economy and almost everybody in it, and that means less than 2pc.

Everything points to conditions being much worse than that right now.

We could just as easily define it as six months of high gold prices — just like the present.

Ronald Reagan had a stab with, “A recession is when your neighbor loses his job.”

Ominously he added, “A depression is when you lose your’s.”

Here we go again. Yesterday’s news of trouble at JP Morgan, America’s second biggest bank, is today matched by Royal Bank of Scotland, the UK’s second largest. RBS is another huge loser in the American subprime mortage market and is set to announce big writedowns next week.

RBS is understood to be seeking to raise capital from its shareholders in a rights issue thought to amount to £10 billion ($20bn), which is probably the biggest rights issue ever demanded in the UK.

The bank, which bought troubled NatWest and ABM Amro, has been running on low capital ratios for quite a while. It also has major exposure to subprime debt instruments. It has been linked with Spain’s Banco Santander for many years.

When such a major player is caught short like this, it brings home the extent and depth of the crisis in transatlantic financial markets, with all the knockon effects to the rest of the world.

Vince Cable, a spokesmen on Treasury matters who carries more weight than the Treasury these days, believes all the banks should follow the example of RBS, since they will need a great deal of liquidity from the Bank of England and that should be underwritten by shareholders, not taxpayers.

Next week’s announcement will be awaited with some trepidation.
