Editor's Note: This column updates the original Vox columns by Barry Eichengreen and Kevin O’Rourke comparing today’s global financial crisis to the Great Depression. The previous columns have shattered all Vox readership records with over 450,000 views (O’Rourke and Eichengreen 2009). The latest data cover up to February 2010, the original April 2009 column and the subsequent updates appear below. Click here to read the original column.

Global output

Global industrial production continues to recover – something for which policy deserves considerable credit (as we have argued on this site, see Almunia et al 2009 and O’Rourke and Eichengreen 2009). But before indulging in self-congratulation, policymakers should note that the level of industrial production is still 6% below its previous peak (figure 1). (At the trough it was 13% below its previous peak.) It follows that considerable excess capacity remains in a number of important economies. Exiting now from policies of stimulus in those countries would therefore be premature.

World trade

World trade also continues to recover but remains 8% below its previous peak (figure 2). (At the trough it was 20% below its previous peak.) The roots of this collapse of trade remain to be fully understood, although recent research has begun to shed light on some of the causes (see Baldwin 2009 and Chor and Manova 2009).

Equity markets

World equity markets are now 25% below peak (figure 3). (At their trough they were 50% below peak.) There was a break in the upward trend in January 2010 that may signal investors’ growing concern about the danger of a double dip – although if the crisis has taught us anything, it has taught us that too much should not be made of the forecasting ability of financial markets.

Start of second update (published June 2009); original column (published 6 April 2009) appears below

Editor’s note: The original Vox column by Barry Eichengreen and Kevin O’Rourke shattered all Vox readership records (30,000 views in two days, over 100,000 in a week, now fast approaching 350,000). Here the authors provide updated charts, presenting monthly data up through June 2009 (or latest).

What do the new data tell us?

  • Global industrial production now shows clear signs of recovering.

This is a sharp divergence from experience in the Great Depression, when the decline in industrial production continued fully for three years. The question now is whether final demand for this increased production will materialise or whether consumer spending, especially in the US, will remain weak, causing the increase in production to go into inventories, leading firms to cut back subsequently, and resulting in a double dip recession.

  • Global stock markets have mounted a sharp recovery since the beginning of the year. Nonetheless, the proportionate decline in stock market wealth remains even greater than at the comparable stage of the Great Depression.
  • The downward spiral in global trade volumes has abated, and the most recent month for which we have data (June) shows a modest uptick. Nonetheless, the collapse of global trade, even now, remains dramatic by the standards of the Great Depression.

Start of first update (published 4 June 2009); original column (published 6 April 2009) appears below

Editor’s note: The 6 April 2009 Vox column by Barry Eichengreen and Kevin O’Rourke shattered all Vox readership records, with 30,000 views in less than 48 hours and over 100,000 within the week. The authors will update the charts as new data emerges; this updated column is the first, presenting monthly data up to April 2009. (The updates and much more will eventually appear in a paper the authors are writing a paper for Economic Policy.)

New findings:

  • World industrial production continues to track closely the 1930s fall, with no clear signs of ‘green shoots’.
  • World stock markets have rebounded a bit since March, and world trade has stabilised, but these are still following paths far below the ones they followed in the Great Depression.
  • There are new charts for individual nations’ industrial output. The big-4 EU nations divide north-south; today’s German and British industrial output are closely tracking their rate of fall in the 1930s, while Italy and France are doing much worse.
  • The North Americans (US & Canada) continue to see their industrial output fall approximately in line with what happened in the 1929 crisis, with no clear signs of a turn around.
  • Japan’s industrial output in February was 25 percentage points lower than at the equivalent stage in the Great Depression. There was however a sharp rebound in March.

The facts for Chile, Belgium, Czechoslovakia, Poland and Sweden are displayed below; note the rebound in Eastern Europe.

Start of original column (published 6 April 2009)

The parallels between the Great Depression of the 1930s and our current Great Recession have been widely remarked upon. Paul Krugman has compared the fall in US industrial production from its mid-1929 and late-2007 peaks, showing that it has been milder this time. On this basis he refers to the current situation, with characteristic black humour, as only “half a Great Depression.” The “Four Bad Bears” graph comparing the Dow in 1929-30 and S&P 500 in 2008-9 has similarly had wide circulation (Short 2009). It shows the US stock market since late 2007 falling just about as fast as in 1929-30.

Comparing the Great Depression to now for the world, not just the US

This and most other commentary contrasting the two episodes compares America then and now. This, however, is a misleading picture. The Great Depression was a global phenomenon. Even if it originated, in some sense, in the US, it was transmitted internationally by trade flows, capital flows and commodity prices. That said, different countries were affected differently. The US is not representative of their experiences.

Our Great Recession is every bit as global, earlier hopes for decoupling in Asia and Europe notwithstanding. Increasingly there is awareness that events have taken an even uglier turn outside the US, with even larger falls in manufacturing production, exports and equity prices.

In fact, when we look globally, as in Figure 1, the decline in industrial production in the last nine months has been at least as severe as in the nine months following the 1929 peak. (All graphs in this column track behaviour after the peaks in world industrial production, which occurred in June 1929 and April 2008.)  Here, then, is a first illustration of how the global picture provides a very different and, indeed, more disturbing perspective than the US case considered by Krugman, which as noted earlier shows a smaller decline in manufacturing production now than then.

Similarly, while the fall in US stock market has tracked 1929, global stock markets are falling even faster now than in the Great Depression (Figure 2). Again this is contrary to the impression left by those who, basing their comparison on the US market alone, suggest that the current crash is no more serious than that of 1929-30.

Another area where we are “surpassing” our forbearers is in destroying trade. World trade is falling much faster now than in 1929-30 (Figure 3). This is highly alarming given the prominence attached in the historical literature to trade destruction as a factor compounding the Great Depression.

It’s a Depression alright

To sum up, globally we are tracking or doing even worse than the Great Depression, whether the metric is industrial production, exports or equity valuations. Focusing on the US causes one to minimise this alarming fact. The “Great Recession” label may turn out to be too optimistic. This is a Depression-sized event.

That said, we are only one year into the current crisis, whereas after 1929 the world economy continued to shrink for three successive years. What matters now is that policy makers arrest the decline. We therefore turn to the policy response.

Policy responses: Then and now

Figure 4 shows a GDP-weighted average of central bank discount rates for 7 countries. As can be seen, in both crises there was a lag of five or six months before discount rates responded to the passing of the peak, although in the present crisis rates have been cut more rapidly and from a lower level. There is more at work here than simply the difference between George Harrison and Ben Bernanke. The central bank response has differed globally.

Figure 5 shows money supply for a GDP-weighted average of 19 countries accounting for more than half of world GDP in 2004. Clearly, monetary expansion was more rapid in the run-up to the 2008 crisis than during 1925-29, which is a reminder that the stage-setting events were not the same in the two cases. Moreover, the global money supply continued to grow rapidly in 2008, unlike in 1929 when it levelled off and then underwent a catastrophic decline.

Figure 6 is the analogous picture for fiscal policy, in this case for 24 countries. The interwar measure is the fiscal surplus as a percentage of GDP. The current data include the IMF’s World Economic Outlook Update forecasts for 2009 and 2010. As can be seen, fiscal deficits expanded after 1929 but only modestly. Clearly, willingness to run deficits today is considerably greater.

Conclusion

To summarise: the world is currently undergoing an economic shock every bit as big as the Great Depression shock of 1929-30. Looking just at the US leads one to overlook how alarming the current situation is even in comparison with 1929-30.

The good news, of course, is that the policy response is very different. The question now is whether that policy response will work. For the answer, stay tuned for our next column.
