There is an overall considerable theme of what you may find when a liquidity tide recedes as most major crises or risk pullbacks have been precipitated by either combination of tighter monetary or fiscal policy. 

 

Some with a considerable lag like a year after Greenspan departed from Fed helm, or many other examples.  I'm not suggesting NOW is a time for a compression in risk but am aware of the possibility, especially when Fed Chairs take victory laps, Bernanke this week.  Symbolic if nothing more.
