Well, everyone agrees today is a Valentine's Day massacre, with growth slashed (or, I suppose, riddled with bullets) worldwide.

• In Japan, GDP shrunk by 0.1 per cent in the last quarter against expectations of 0.1 per cent growth.
• In Germany, GDP contracted by 0.6 per cent in the last quarter.
• In France, it fell by 0.3 per cent over the same period.
• In Italy, by 0.9 per cent.
• Portugal declined by 1.8 per cent.
• In Greece, GDP is reported in comparison with the same quarter in the previous year. The level at the end of Q4 2012 was 6 per cent lower than in Q4 2011.
• The Eurozone as a whole contracted by 0.6 per cent, worse than expectations of a 0.4 per cent contraction.

That's the worst performance in almost four years for the Eurozone, and an alarming decline on even the post-crisis trend, as this chart from Natixis Asset Management's Philippe Waechter, via Business Insider, shows:

Not a very happy Valentine's day for most of Europe, then.
