Another month, another confirmation that when it comes to the US consumer, it is all about student debt (and to a lesser extent, car loans). Moments ago the Fed reported that consumer credit number for March: at $17.5 billion, it not only blew out the expectation of a $15.5 billion increase (although when one adds last month’s $3.5 billion downward revision to $13.0 billion the two month total actually missed), but was the highest monthly increase since February 2013. That’s the good news.
