      A year later, in January 2009, in the aftermath of the collapse of Lehman Brothers and all the other financial turbulence in autumn 2008, things looked very different. The outlook was for recession across the world economy with sharp declines in output in all the major Western economies. Under the headline ‘Global Economic Slump Challenges Policies’, the IMF predicted that world growth would be just 0.5% in the year ahead, the weakest year for global growth since 1950 at least.3 In fact this was an underestimate of the scale of the downturn – world GDP actually fell in 2009 for the first time since World War II.

      Going back to the start of the 20th century, there are only two other peacetime years when the outlook for the world economy deteriorated as dramatically as in 2008. One is 1930, which marked the onset of a prolonged depression in the United States and Europe after the Wall Street Crash of 1929, bringing to an end the prosperity of the ‘roaring twenties’. The other is 1974, when the long post-war boom came to an end amidst rampant inflation, rocketing oil prices and financial turbulence. That year ushered in a long period of economic turmoil in many economies which continued until the mid-1980s.

      The Great Stability

      As in the 1930s and the mid 1970s, policymakers were unprepared for the big change in the economic climate in the late 2000s. The long period of healthy growth and low inflation since the early 1990s had led to the expectation that big swings in the economy were a thing of the past. In his 2004 Budget speech, the UK Chancellor of the Exchequer Gordon Brown proclaimed:

      Britain is enjoying its longest period of sustained economic growth for more than 200 years… the longest period of sustained growth since the beginning of the Industrial Revolution.4

      This optimistic assessment reflected the positive performance of the British economy since the early 1990s. UK economic growth averaged 3.3% per annum between 1993 and 2007 – very impressive by past historical comparisons and in line with the growth rate Britain had achieved in the post-war golden age from the late 1940s until the early 1970s. Even in the weakest year for UK economic growth between 1993 and 2007 – in 2002 – GDP grew by 2.4%, despite a weak global economy in the aftermath of the 9/11 attacks. (This ‘weak’ GDP rise in 2002 is still stronger than any year of growth we have seen so far since the financial crisis!)

      Alongside this healthy rate of economic growth, low and stable inflation reinforced the widespread perception of economic stability. For two decades, from the early 1970s until the early 1990s, UK policymakers had battled to subdue inflation. The annual rate of increase in prices had hit a peak of nearly 27% in the summer of 1975 – averaging over 13% in the 1970s and running at 6% through the 1980s. But from 1993 until 2007 – with monetary policy explicitly targeting a low and stable rate of inflation – the British economy enjoyed its longest and most sustained period of price stability since World War II.5 The establishment of the Bank of England Monetary Policy Committee in 1997, with independent control over monetary policy, reinforced the view that low inflation was now institutionalized in the United Kingdom. The Governor of the Bank of England was expected to write an explanatory letter to the Chancellor of the Exchequer if inflation deviated more than one percentage point from the target. When I joined the MPC in the autumn of 2006, nearly a decade had elapsed without one of these letters being written – though the first was despatched in March 2007, and thirteen more have been written since then!

      The United Kingdom was not the only economy experiencing these benign economic conditions. In the United States, there was also a belief that their economy had entered a prolonged period of sustained growth and low inflation known as the ‘Great Moderation’. Like the United Kingdom, this view was reinforced by a high degree of confidence in the ability of the central bank to maintain sustained economic growth and stable prices. In the early 2000s, under its chairman Alan Greenspan, the US Federal Reserve had cut interest rates aggressively to steer the US economy away from recession when the dotcom US stock market bubble burst. And in the mid 2000s there was great confidence in the ability of Greenspan’s successor, Ben Bernanke, to do something similar if the situation demanded it. Meanwhile, the establishment of the euro as a single currency was seen as a stabilizing force for the European economy – anchored by a European Central Bank modelled on the Deutsche Bundesbank, which had successfully held back inflationary pressures and countered economic volatility in the 1970s and 1980s.

      Reflecting the mood of these times, the Bank of England hosted a major international conference in September 2007 aimed at understanding the sources of macroeconomic stability.6 It was highly ironic that as economists and policymakers gathered in London to understand why Western economies had become so stable, confidence in the Great Stability was being undermined on the streets of cities and towns across the United Kingdom. Queues were forming outside branches of Northern Rock as customers sought to take their money out of the bank. When the Bank of England and the UK government appreciated the severity of the crisis, they intervened to rescue Northern Rock. But a year later, in the autumn of 2008, the financial turbulence hit other much larger banks – including Royal Bank of Scotland, HBOS, Citibank and Lehman Brothers. By then, it was clear then that the era of the Great Stability had already come to an end.

      The Global Financial Crisis: A rude awakening

      The financial crisis of 2008–9 provided a rude awakening from excessively optimistic views about our ability to maintain a long and sustained period of economic growth. It was also a reminder that, however adept national economic authorities were, developments in the global economy were a potential source of economic instability. Indeed, even before I joined the MPC in 2006, it was clear that international rather than domestic factors were the main sources of volatility driving changes in UK monetary policy.

      The MPC was established in 1997 just before the onset of the Asian financial crisis, which threatened the growth of the global economy. This was followed in the late 1990s and early 2000s by the dotcom boom and bust which had its roots in excessive optimism about the ability of information technology and the Internet to transform the prospects of the US economy. The weakness of the global economy in the early 2000s was reinforced by international political instability following the 9/11 attacks and then war in Afghanistan and Iraq. But just as the world economy emerged from this period of turbulence, we started to see surges in global energy and commodity prices. The price of oil, which had been stable at around $20/barrel for most of the 1990s and early 2000s surged to over $50/barrel in 2004 and hit $80/barrel in 2006 just before I joined the MPC. Two years later it had reached nearly $150/barrel.

      When facing global shocks of this sort, a central bank in a single country like the United Kingdom can only do a limited amount to offset their economic impact. As long as the shocks are not too big, it is possible to keep the economy on a reasonably steady growth and low inflation track – which is what happened in most Western economies through the period from 1993 until 2007. But the global financial crisis exposed the limits of the ability of national authorities to stabilize economies in the face of such a severe global economic shock. Even though interest rates were cut to rock bottom levels and other emergency measures taken to stabilize the financial system around the world, a major world recession could not be avoided. Between 2007 and 2009, GDP fell in the G7 economies by over 4%, with the decline varying between 1.7% (Canada) and 6.6% (Italy and Japan) – leading to a rise in unemployment rose around the world.

      To counter this severe economic downturn, policymakers unleashed a whole raft of measures to provide emergency support to their economies and stabilize the financial system. Governments took financial stakes in banks and allowed their borrowing to rise to cover this. Central banks cut official interest rates to rock-bottom levels. In the United Kingdom, the Bank Rate of 0.5% we set in March 2009 is the lowest seen in recorded history – lower even than in the Great Depression of the 1930s when the official rate of interest did not fall below 2%. Money was also injected into economies through central bank purchases of government bonds and other assets – under a policy with the unappetizing title of quantitative easing. And for a while governments were prepared to increase their spending and СКАЧАТЬ
