Federal Reserve set for an extended pause
The minutes from the December meeting noted that usage of the overnight reverse repo facility remained on a declining trend, reflecting money market fund reallocation to Treasury bills and private-market repo, which offered slightly more attractive market rates. This occurred against a tightening in market repo conditions, and continued increases in net Treasury bill issuance. At that meeting, the Fed also reduced the rate it pays at the reverse repo window by 5bp, back to flat to the funds rate floor. This adds to the attraction of market repo, and should correlate with further falls in the use of the reverse repo window. Our view is that usage of the reverse repo window will ultimately fall towards zero, barring some temporary spikes around month end.
The Fed may or may not comment on the above. It will also be interesting to see whether the Fed comments on the resurrection of the debt ceiling since 2 January 2025. While it’s too early to expect a material market focus on it, the technical aspects of it are impactful. As long as the debt ceiling remains in place and the Treasury employs extraordinary measures to avoid breaching it, there is a tendency to spend down the cash balances that it holds at the Fed. As these get spent down, they add to reserves in the system which in turn acts to counter the tightening effect of the ongoing quantitative tightening (QT) programme. In effect, hitting the debt ceiling forces the Treasury to be a net supplier of liquidity to the system.
Despite these complications, the Fed may well lay the groundwork for ending QT at some point in 2025. This is the case as excess liquidity (which we define as bank reserves plus reverse repo balances) is likely to hit levels that the Fed would prefer not to go below from the middle of 2025 onwards, partly depending on how the debt ceiling saga evolves. The key number here is US$3tn for reserves, representing about 10% of GDP. We are currently at US$3.5tn. So we’re comfortable. At the same time, the reverse repo balance is running at US$125bn, and if that were to hit zero, then we’d hit some degree of tightness. That’s close, as QT is running at US$60bn per month. QT may have to end by mid-2025 based on a simple extrapolation of this.
