A couple of weeks old but an interesting Bloomberg article showing empirical evidence of a rapid deterioration of financial liquidity since the Fed raised interest rates in December by just 25 basis points.

"The combination of these two factors has led to a somewhat vicious cycle and feedback loop, where poor liquidity is spreading, and liquidity problems appear to be turning into fundamental problems," the pair wrote. "Moreover, tightening of monetary policy by the Fed, first through tapering and now through tightening, may have been necessary from an economic perspective, but the tightening appears to be adding fuel to the fire of liquidity deterioration."
