It was hardly a well-kept secret. The Bank of England had received a raft of appalling numbers from the real economy this week. It was bound to cut rates deep today.

An hour ago, the Old Lady of Threadneedle Street duly obliged and cut by 100 basis points to two percent, the lowest figure since 1951.

It is clear that this is going to be a steeper and longer slump than most forecasters would own to until very recently. Next year will see the deepest of economic winters across the world.

Reflecting the gloomy forecasts, other central banks are slashing rates too.

Sweden’s central bank today cut its key rate by a record 175 basis points, to two percent, the largest since 1992 when the country famously nationalized its major banks.

New Zealand also announced a cut of 150 basis points to a five-year low of five percent. Further cuts are on the cards.

Indonesia made a surprise 25 basis-point cut to its rate, to 9.25 percent.

Yesterday, the Bank of Thailand cut rates by 100 basis points to 2.75 percent, some of which may have been due to recent political turmoil in the country.

On Tuesday, the Reserve Bank of Australia surprised markets with a 100 basis-point cut to 4.25 percent.

The European Central Bank is expected to cut again today, but signals are mixed. The Shadow ECB has called for swift, deep cuts from its current rate of 3.25 percent. However, voices close to the ECB warned not to expect them. The lack of a strategy is a major criticism of the “Bank without a Treasury”.

All bank authorities are aware that 2010 is the year when inflation will return with a vengeance if a prolonged deflation can be avoided. Most are fighting the latter tooth and nail, while making noises about having the medium term under control.

We shall see.

Can we really have witnessed the demise of three top investment banks in so short a time? Bears Stearns, Lehman Brothers and Merrill Lynch have all disappeared off the radar in quick succession.

What is happening to the world’s — and especially the American’s — financial system?

It started with the slicing, dicing and splicing of U.S. mortgages of sub-prime customers. The structured financial instruments that were sold off around the world became known as CDOs (Collateralized Debt Obligations).

They have poisoned the world’s financial system, like seeping toxic waste. Now a new danger is forming on the horizon.

CDSs (Credit Default Swaps — insurance policies for bonded commercial IOUs), which are out there in their trillions and trillions, are beginning to crumble in the face of massive defaults.

The world’s biggest insurer AIG is already in Lehman territory — its shares plummeted by 70 percent in early trading yesterday. The long-foretold CDS crisis is with us at last.

So what precisely are CDSs and how will their demise affect most of us in coming days, weeks, months and years?

George Soros estimates that the value of CDSs now equals half of U.S. household wealth, an almost unimaginable number — let’s call it $23 trillion.

CDSs are hedges made by investors in case a company defaults on its debts. In effect you bet on a company failing to protect your investment in the event it does just that. The problem arises when large numbers of companies go bust and the CDSs themselves become worthless since no-one can pay them out.

A CDS seller undertakes to compensate a buyer if a corporate bond defaults. Since there is no limit to the size of cover taken out, the value of CDSs often exceeds a company’s debts. Moreover, many CDSs are bought with borrowed money so the infection of the system drives deep into the financial heartland like veins in a blue cheese.

The danger now is debt deflation: a rapid reversal of debt issuance, or deleveraging as it is called.

Tim Congdon of the London School of Economics says, “Banking system capital is being wiped out. The risk is that this could lead to a contraction of credit and set off a self-reinforcing downward spiral, leading to the sort of debt-deflation we saw in the 1930s.

“It is already clear that money growth has ground to a halt over the past three months. We must prevent it from actually contracting. If the Fed and European Central Bank don’t cut interest rates soon, it is going to be a problem.”

The Bank of England’s rigid inflation target, set by Gordon Brown when inflation was low, is now a millstone round Mervyn King’s neck at a time when energy, food and commodity price rises are being imported from global markets.

The Eurozone is similarly caught in a time warp relating to Germany’s neurotic fear of hyperinflation. Add the growing divergence between euro economies and a far deeper than necessary downturn is guaranteed for Western European countries.

America is already suffering a double blow: the fading of the effect from the summer tax stimulus and a loss of export competitiveness as the dollar rises.

What began as bad government, worse regulation, grasping banks, financial structures that lacked resilience because they were built on sand, have left us with a perfect storm that is about to come ashore and swallow large parts of the economy.

The European Central Bank (ECB) today defied the threat of recession in many eurozone countries and raised interest rates to their highest level for almost seven years, despite frantic political pressure.

ECB President, Jean-Claude Trichet, issued a strong warning on Wednesday that inflation in the zone could explode if left unchecked.

The decision by the ECB’s Governing Council is set against calls to hold firm from European leaders led by President Sarkozy of France. It comes after a leap in eurozone inflation to 4pc in June which set alarm bells ringing over price pressures. This was further fuelled by a rise in factory-gate producer prices within the eurozone, which jumped 1.7pc in May, to stand 7.1pc up on a year earlier. The hike was largely driven by an 18.2pc year-on-year rise in energy costs.

More depressing numbers were released today confirming that the eurozone’s services sector, which is at the heart of its economy, shrank in June for the first time since mid-2003.

Economists pointed out new indications of “stagflation” in the eurozone economy, with output contracting as price pressures continue to build. They believe that today’s interest rate increase is a single-shot for the rest of the year.

Could that be more in hope than expectation though?
