Now let's stick it alongside the one Paul Krugman put up last week of the US Great Depression:
Arguably, what we can see here is that the current collapse in industrial activity is starting to get near the US historic one in terms of proportions, but we still aren't quite there yet. What we could note that JP Morgan in their monthly report suggest that the present rates of output are equivalent to an annual fall of between 12% and 15%. Really to compare with the fall in the US we need to get up into the 20% region, but remember the global index is based on an average for 26 countries, and some of these are much worse than others (Japan, Spain, possibly Russia) and will already be around the 20% annual contraction rate in December. The point is also that the situation is still deteriorating, so hang on a bit, since it is not at all excluded that we will hit a 20% annualised contraction rate for the whole aggregate 26 sometime during the first quarter.
"The second half of 2008 has been dreadful for global manufacturing and the sector enters the new year mired in its deepest recession for decades. Manufacturing will therefore continue to weigh on world GDP figures, with December PMI data consistent with a drop in global IP of around 12%-15% saar as indexes for output, new orders and employment slumped to record lows."
"The weakest performance was registered by Japan, whose output and new orders indexes fell to levels unprecedented in the histories of any of the national manufacturing surveys included in the global manufacturing PMI."
"Employment fell for the fifth successive month in December, and to the greatest extent in survey history. All of the national manufacturing sectors recorded a drop in staffing levels, most at series-record rates including all of the Eurozone nations, China and the UK. The sharpest falls in employment were signalled for Denmark, Spain, the US, Russia and the UK."
And watch out for the deflation backslap:
"The Global Manufacturing Input Prices Index posted 31.3, its lowest ever reading. The rate of deflation was especially marked in the US, were purchase prices fell to the greatest extent since June 1949. Rates of decrease in costs hit series records in the Eurozone, Russia, Switzerland, the Czech Republic and Denmark."
And for those of you who are still sceptical that any of this has any validity, here's a PMI/GDP comparison chart for Japan - GDP rates to the left, diffusion index PMI readings to the right (click over image if you can't view too well). Not perfect, but not a bad guide I would say, if you like your football live, that is.
So never mind the depth, what about the duration? Well that is where I think that all of this will differ from what happened back then. As you can see in the US Great Depression Chart the 20% annual decrease went on for several years. At the present time I think there is no reason to assume that this will happen, ie that we will keep getting massive year on year contractions (in some cases maybe, Latvia perhaps?????), but activity does look set to fall to quite a low level, and there is no strong reason at present for believing it will simply bounce back up again. More than likely we will simply trawl the bottom, at least for some months, and who knows, maybe a couple of years.
Well that's it for the big picture stuff, but I have actually been pretty hard at it all day down at the individual country level, so there is plenty more detail to come. In forthcoming posts.
