From Zero Hedge:
As the first major exporting nation to report each month, all eyes and hopeful speculative capital was glued to tonight's South Korean trade data. After a brief respite in November, December's drop was worrisome, but January's just reported 18.5% crash - the most since the financial crisis - has only been seen during a US economic recession. Worse still, South Korean imports plunged over 20% in January as it appears crashing crude and cliff-diving freight indices are less about supply and more about demand (there is none) after all.

Furthermore, with China accounting for around one quarter of South Korean exports - and following a 16.5% YoY plunge in December - tonight's headline data suggests January was a total disaster for the Chinese economy also... though later we will get the PMI data to explain everything.
