It appears there is just a little excess liquidity sloshing around out there. Moments ago the Fed announced that as part of its most recent overnight reverse repo "liquidity withdrawal preparedness test [4]", some 87 entities provided the Fed with a whopping $58.2 billion in overnight liquidity in exchange for Treasury collateral at a 0.01% stop out rate. This was the largest amount in liquidity soaked up (or, alternatively, collateral provided) by the Fed in its recent history of Temporary Open Market operations [5]going back to 2012.
