It was the year when people finally gave up trying to predict the year ahead. It was the year when every forecast had to be revised - usually downwards - at least three times. It was the year when the paradox of globalisation was laid bare for all to see, if their eyes weren't tightly shut.
On the one hand, the increasing integration of markets for commodities, manufactures, labour and capital had led to great gains. As Adam Smith had foreseen in The Wealth of Nations, economic liberalisation had allowed the division of labour and comparative advantage to operate on a global scale. From the 1980s until 2007, the world economy had enjoyed higher, more widespread growth and fewer, less severe crises - hence Federal Reserve chairman Ben Bernanke's hubristic celebration of a "great moderation" in 2004.
On the other hand, the more the world came to resemble an intricate, multi-nodal network operating at maximum efficiency - with minimal inventories and just-in-time delivery - the more vulnerable it became to a massive systemic crash.
That was the true significance of the Great Repression which began in August 2007 and reached its nadir in 2009. It was clearly not a Great Depression on the scale of the 1930s, when output in the US declined by as much as a third and unemployment reached 25 per cent. Nor was it merely a Big Recession. As output in the developed world continued to decline throughout 2009 - despite the best efforts of central banks and finance ministries - the tag "Great Repression" seemed more and more apt: although this was the worst economic crisis in 70 years, many people remained in deep denial about it.
"We assumed that we economists had learned how to combat this kind of crisis," admitted one of President Barack Obama's "dream team" of economic advisers, shortly after his return to academic life in September 2009. "We thought that if the Fed injected enough liquidity into the financial system, we could avoid deflation. We thought if the government ran a big enough deficit, we could end a recession. It turned out we were wrong. So much for [John Maynard] Keynes. So much for [Milton] Friedman."
The root of the problem remained the US's property bubble, which continued to deflate throughout the year. Many people had assumed that by the end of 2008 the worst must be over. It was not. Economist Robert Shiller's real home price index in 2006 had stood at just under 206, nearly double its level just six years earlier. To return to its pre-bubble level, it therefore had to fall by 50 per cent. Barely half that decline had taken place by the end of 2008. So house prices continued to slide in the US. As they did, more and more families found themselves in negative equity, with debts exceeding the value of their homes. In turn, rising foreclosures translated into bigger losses on mortgage-backed securities and yet more red ink on banks' balance sheets.
With total debt above 350 per cent of US gross domestic product, the excesses of the age of leverage proved difficult to purge. Households reined in their consumption. Banks sought to restrict new lending. The recession deepened. Unemployment rose towards 10 per cent, and then higher. The economic downward spiral seemed unstoppable. No matter how hard they saved, Americans simply could not stabilise the ratio of their debts to their disposable incomes. The paradox of thrift meant that rising savings translated into falling consumer demand, which led to rising unemployment, falling incomes and so on, ever downwards.
"Necessity will be the mother of invention," Obama declared in his inaugural address on January 20. "By investing in innovation, we can restore our faith in American creativity. We need to build new schools, not new shopping malls. We need to produce clean energy, not dirty derivatives." Commentators agreed that the speech was on a par with Franklin Roosevelt's on his inauguration in 1933. Yet Roosevelt had spoken after the worst of the Depression was over, Obama in mid-tailspin. The rhetoric flew high. But the markets sank lower. The contagion spread inexorably from subprime to prime mortgages, to commercial real estate, to corporate bonds and back to the financial sector. By the end of June, Standard & Poor's 500 Index had sunk to 624, its lowest monthly close since January 1996, and about 60 per cent below its October 2007 peak.
