For a global economy that is "improving" we sure are getting a whole lot of records in the won't direction in the last two days. Yesterday it was Japan which printed a record current account deficit (yes, the most indebted country in the world was once upon a time supposed to export its way out of debt). Today, we learn that in February the US will report its largest budget deficit in history, as the Keynesian floodgates open full bore, and as Zero Hedge has noted repeatedly, tax revenues just refuse to come in at anything close to the pace of accelerated spending, forcing the US to borrow 54 cents for every dollar it spends (not the often cited 42 cent number which does not take into account tax refunds - see here). We would comment more on this, but frankly the chart speaks for itself. And now that the US has to fund an additional $100 billion due to the taxcut extension this means that things are only going to get worse, fast.
