WHEN the dust eventually settles, the origins of the 2008 financial crisis will probably be linked to two key developments in the global economy since 2003.

The first was its rapid growth. The world economy grew by an average of 5 per cent per annum from 2003 to 2007. Growth was supported by relatively low interest rates and easy access to credit. This was especially true in the United States, where sophisticated financial instruments made it easy to use illiquid housing wealth to support consumption.

Economic growth was even higher in emerging markets. Rising global demand for resources, together with ill-advised petrol subsidies and government sponsored food-to-biofuel programmes in industrialised nations, fanned a commodity price boom. Food prices nearly doubled between 2000 and mid-2008, and crude oil prices reached a record high of US$146 in June this year. The inevitable outcome was higher inflation.

The second development was the emergence of significant macroeconomic imbalances between the US, on the one hand, and Asia and oil exporting nations, on the other. The US current account deficit averaged more than 5 per cent of its GDP in the 2001-2008 period, against only 3.5 per cent during the 1980s.

Excess savings in emerging markets and an insatiable demand for its assets enabled the US to finance its current account deficit without significant upward pressure on interest rates.

The potential for adverse effects of these two developments coming together - high growth and global macroeconomic imbalances- became apparent in early 2006. Cheap credit contributed to US housing prices increasing by 125 per cent from 1997 to 2005. Low initial interest rates, together with the irrational expectation of housing prices continuing to rise, encouraged sub-prime borrowers to obtain adjustable rate mortgages that would be difficult to service once interest rates rose.

And rise they did. For the Federal Reserve gradually raised its federal funds rate from a low of 1 per cent in May 2004 to 5.25 per cent in June 2006. It did so, not so much to prick the housing bubble, as to stem inflationary pressures. Rates remained high till August last year, when the sub-prime mortgage crisis first surfaced. The US housing bubble would have burst anyway, but the Fed's actions merely hastened the inevitable.

What was so special about this housing boom and bust cycle? Cycles in housing markets are not uncommon events. But what made the recent US housing cycle stand out, however, was the systematic failure of market participants to appreciate the financial risks they faced should house prices fall.

The securitisation of mortgages in the US had enabled more investors to purchase shares in shaky housing loans. Credit default swaps (CDSs) - which are essentially insurance derivatives - transferred the risk of default from holders of mortgage-backed securities (MBSs) to CDS providers. But the CDS market itself, being unregulated and undercapitalised, added to the systemic risk.

Investment banks, aided by a 2004 Securities and Exchange Commission ruling that allowed them to almost double their debt-capital ratio to 30:1, also helped multiply the volume of MBS holdings and broaden their sales worldwide. Who would have imagined that securitised products - such as Lehman's Minibonds and Merrill Lynch's Jubilee Notes - would end up being sold to retirees in Singapore?

Securitisation of sound mortgages clearly has desirable effects because they spread the underlying risks across many investors. This crisis was caused by the systemic failure of market participants to appreciate the size of the default risk. Moral hazard, imperfect corporate governance and regulatory failures were largely to blame.

By March this year, an estimated 8.8 million homeowners in the US had zero or negative equity in their homes. The growing risk of MBS default sent shudders through the financial system. Even financial institutions without MBS holdings became wary, because they had made loans to institutions with MBS holdings. When several major financial institutions failed last month, perceptions of risk escalated and caused credit markets - the blood line of the global economy - to seize.

Having a financial crisis with failing banks is bad enough; having one along with rapidly eroding borrower and lender confidence and a credit squeeze is a recipe for a global recession.

Why? Most countries are linked by an elaborate web of international capital flows and trade linkages to the US, the world's biggest economy and its most important financial centre. Through the financial linkages, a major financial crisis in the US quickly becomes a global crisis. And because of trade linkages, a global economic slowdown reduces world trade, further constricting growth in a vicious downward cycle.

Indeed, the Great Depression of the 1930s, which started in the US, lasted several years after the initial stock market crash, largely because of competitive protectionist or beggar-thy-neighbour trade policies. But that period also left policy makers with many hard-earned lessons on what needs to be done to contain a major financial crisis.

First, central banks must expand rather than contract the money supply. Second, strong national leadership is required to prevent bank runs and to restore confidence in the banking system. And third, strong world leadership is required to dissuade countries from pursuing unilateral 'solutions' that have an adverse impact on others.

All three actions were lacking in the 1930s. Fortunately, they were taken in the current financial crisis. In response to the credit market freeze, central banks pumped liquidity into the system. When this step failed to restore confidence, governments announced plans to use public money to remove toxic assets from financial balance sheets and even to recapitalise banks.

At the international level, there was coordination among the major central banks to slash interest rates, rescue banks that needed capital as well as to guarantee interbank loans, thereby removing counterparty risk. Notwithstanding stock market meltdowns, all these actions appear to have improved confidence in the financial system.

That said, damage has already been inflicted on the real economy by the global stock market meltdown. There are already signs of declining growth and rising unemployment in many countries, and commodity prices are easing. The risk of negative feedback between the real and the financial sectors remains high, though manageable provided confidence in the financial system is restored.

More can be done to minimise the damage to the real economy. It is time for national governments to unleash countercyclical fiscal measures. In this respect, Asian economies have an advantage over the US because of their high savings rates and large accumulated surpluses. Increased domestic spending in Asia would also narrow existing current account imbalances in the global economy.

Last but not least, attention must be directed to rework the regulatory system. The prime objective of the financial sector is to serve the real economy by channelling capital and liquidity to its most productive use. Financial markets need to be better regulated to avoid the build-up of excesses that can damage the real economy. But over-zealous regulation must also be avoided so as not to hamper the efficient workings of the financial system.

It is indeed a challenge to design a regulatory framework that balances these two competing needs.
