Perli: Treasury Bill Purchases Not on a Preset Path; Will Monitor October Net Issuance Shock
nashnova research
NY Fed SOMA manager Roberto Perli said reserve management purchases have been dialed to zero and are not on a preset path — October's expected surge in net T-bill issuance will be the key test of whether buying needs to restart.
Reserve management purchases are paused — what does that actually mean?
The Fed buys Treasury bills through the NY Fed's open-market desk to keep bank reserves at an "ample" level. These operations are called reserve management purchases, or RMP.
Perli made clear: RMP is not on autopilot. The purchase pace is now zero, but the FOMC has authorized the desk to adjust it at any time as market conditions evolve.
This means → a pause is not an exit. The Fed retains the option to resume buying the moment it judges reserves need support.
Why pause specifically through October?
Earlier this month the Fed extended an RMP pause — originally started in August — through mid-October, while still planning roughly $15.6 billion in reinvestment purchases.
Perli flagged October as a stress-test moment: markets expect a fresh wave of large net T-bill issuance around that time, and the Fed wants to see whether the market can absorb it on its own.
In plain terms = the Fed is saying: "We'll stand aside and watch. If the market can't digest the October supply wave, we step back in."
What metrics will the Fed use to decide whether to restart?
Perli named two monitoring channels: senior financial officials' judgment on market conditions + stress signals in funding markets.
This means → no single trigger — the Fed is blending human judgment with market data, leaving itself wide discretion.
October's actual net issuance volume and the market's reaction will be the first real-world test of whether the pause decision needs revising.
Why did Perli also bring up central clearing?
Perli said the benefits of central clearing for repo operations — routing repo trades through a single central platform — will matter more under a framework that relies more heavily on repos.
This reflects the Fed laying groundwork for upgrading its liquidity-management toolkit: central clearing strengthens counterparties' ability to transmit liquidity through the system.
NY Fed President John Williams said the same day that progress on central clearing for Treasuries and repo agreements has exceeded expectations.
