What if the Fed's headline interest rate decision is pure pantomime?
Fast Track (30 seconds)
Michael Howell argues that the Fed's headline interest rate decision is theatre. The real liquidity signal sits in the plumbing: bank reserves, the repo market, and the spread between SOFR and what the Fed pays banks on reserves. When that spread widens, cash is genuinely scarce, whatever the headline rate says. A recent six month, six hundred billion dollar injection into money markets, triggered by exactly this kind of stress, is Howell's Exhibit A - and, by his account, the real explanation for Wall Street's buoyancy.
- Reserves - cash banks hold on deposit at the Fed,
beyond what they lend out elsewhere.
- EFFR (Effective Federal Funds Rate) - the actual
overnight rate banks charge each other to borrow reserves.
- SOFR (Secured Overnight Financing Rate) - the
overnight rate for cash borrowed against Treasury collateral in the repo
market.
- ON RRP (Overnight Reverse Repo Facility) - where
money market funds park surplus cash with the Fed when reserves are abundant.
- SRF (Standing Repo Facility) - where banks borrow
cash from the Fed against Treasury collateral when reserves are tight.
- IORB (Interest on Reserve Balances) - the rate the
Fed pays banks on reserves; the anchor both EFFR and SOFR are meant to track.
Introduction
Every six weeks or so, financial media treats the Federal Reserve's rate announcement as the most important economic event on the calendar. Michael Howell disagrees, and not mildly. In his view, the meeting itself is close to pantomime: a ritual performance that tells investors almost nothing about the actual state of liquidity in the financial system. The real story, he argues, is happening somewhere most people never look - in the technical plumbing of the banking system, where the Fed and Treasury quietly manage the pressure in a pipe network of reserves, repo markets and collateral.
Why It Matters
If Howell is right, investors who fixate on the Fed funds rate are watching the wrong gauge. The plumbing indicators below move first, move more honestly, and - in Howell's telling - already explain a recent multi hundred billion dollar liquidity injection that the headline rate never predicted. Understanding them is a precondition for understanding where the liquidity cycle, and by extension asset prices, go next.

1. Why Howell Calls the Rate Decision "Pantomime"
The actual volume of lending conducted at the Fed funds rate is small. That is Howell's starting point, and it is the reason he is dismissive of the attention paid to each FOMC meeting.
"Does it really matter that interest rates go up or down? Not really - the amount of transactions in the Fed funds market is diminutive."
He goes further: Kevin Warsh has signalled that under a different Fed leadership, there could be as few as three or four FOMC meetings a year, with no formal forward guidance at all. If the ritual itself may soon be scaled back, Howell's underlying point sharpens - the market's attention has been trained on the wrong signal for years.
What matters instead, in his framing, is what the Fed and Treasury are doing beneath the surface: managing bank reserves, watching wholesale money markets, and tracking how short term borrowing rates behave relative to the Fed's own targets.
2. The Plumbing Gauge That Matters Most: The SOFR Spread
Two overnight rates anchor the system. The Effective Federal Funds Rate (EFFR) is what banks actually charge each other to borrow reserves overnight. The Secured Overnight Financing Rate (SOFR) is the equivalent rate for cash borrowed against Treasury collateral in the repo market. Both are meant to trade close to the rate the Fed pays banks on their reserve balances (IORB), with low volatility.
When they don't - when SOFR spikes away from that anchor - something in the plumbing is under strain. That spread, not the headline target range, is Howell's preferred early warning gauge for stress in short term funding markets.
A widening SOFR spread is a sign of friction in the system long before it shows up anywhere the headline rate can capture.
3. Two Safety Valves: The ON RRP and the Standing Repo Facility
Two Fed facilities sit at opposite ends of the same pipe.
The overnight reverse repo facility (ON RRP) absorbs surplus cash from money market funds and other institutions. When reserves are genuinely plentiful, usage should be minimal. Rising usage signals excess cash sloshing around with nowhere better to go.
The Standing Repo Facility (SRF) does the reverse: it lends cash to banks against Treasury collateral when they are short. Occasional use is normal. Sustained, growing use signals real thirst for liquidity in the banking system - the condition Howell points to directly in the case study below.
4. The Six Hundred Billion Dollar Case Study
Howell points to a concrete recent episode. Over five to six months, the Federal Reserve injected roughly six hundred billion dollars into US money markets. He links that injection directly to the buoyancy of Wall Street over the same period - not as a side effect, but as a central driver.
The trigger, in his account, was that repo markets were growing short of liquidity, visible in exactly the indicator described above: SOFR spiking upward relative to the Fed's target range. The Fed responded not through a rate decision, but through the plumbing - reserve management purchases conducted purely to keep the banking system's cash levels adequate, with no accompanying announcement of the kind that dominates financial headlines.
Bottom Line
The Fed funds rate is a headline. The plumbing - reserves, the SOFR spread, and usage of the ON RRP and Standing Repo Facility - is where the real liquidity story is written. A recent six hundred billion dollar injection, triggered by repo market stress and largely invisible in mainstream coverage, is Howell's case that the plumbing already told investors what the rate decision could not.
Glossary
Reserves. In the Fed's plumbing, this refers to the cash balances that commercial banks hold on deposit at the central bank, above what they lend out elsewhere. Howell treats changes in reserves as more informative than the Fed funds rate itself, since reserve levels are one of the Fed's most direct levers for adding or draining liquidity.
Repurchase agreement (repo). A short term, secured loan structured as a sale and buyback of a security, usually overnight. One party sells a Treasury bond for cash and agrees to buy it back the next day at a slightly higher price; the other holds the bond as collateral. Stress in this market, visible as a spike in the repo rate, spreads quickly into the wider financial system.
Secured Overnight Financing Rate (SOFR). The benchmark rate for borrowing cash overnight against Treasury collateral. It has become the main reference for dollar borrowing costs and is one of Howell's preferred real time gauges of funding stress.
Standing Repo Facility (SRF). Lends cash to eligible banks and primary dealers against Treasury or agency collateral, at a rate set by the FOMC. It acts as a backstop when the repo market is short of cash, and rising use of it signals tightening liquidity in the banking system.
