Open market operations
The tools the New York Fed uses to hold the funds rate in range — and, in size, to change the stock of reserves.
The FOMC votes on a target. The Federal Reserve Bank of New York’s trading desk is directed to achieve it, using the tools the committee authorises in its implementation note.
In the current framework, the primary levers are administered rates — the interest paid on reserve balances, and the rate offered at the overnight reverse repurchase facility — which together set a floor and a soft ceiling on where the funds rate can trade. Outright purchases and sales are used less for day-to-day rate control than they were before 2008. When they are used in size, they are quantitative easing and quantitative tightening: changing the quantity of reserves on purpose, not just pinning an overnight rate.
The desk is plumbing. The stance it implements is a policy choice about credit.
A worked example
Suppose the Committee’s target range is 3.50–3.75 percent. The Fed pays 3.65 percent on reserve balances banks hold with it, so no bank will lend reserves overnight for less than about that. It offers 3.50 percent at the reverse repo facility to a wider set of institutions, which sets a floor beneath the band. Between the two, the effective funds rate settles near the middle of the band. If the Committee cuts by a quarter point, the Fed lowers both administered rates the same day, and the market rate moves with them. No securities need change hands. The figures are a worked example of the mechanism, not a claim about the current setting.
Outright purchases and sales still happen — that is what QE and QT are — but for day-to-day control of the funds rate, administered rates do the work.
How to read it in coverage
The “implementation note” published alongside each FOMC statement is the instruction to the New York Fed and lists the administered rates. When a story says the Fed “injected liquidity”, it usually means a repo operation: a short-term loan against Treasury collateral, reversed days later. That is plumbing, not a change in the stance, and it is routinely mistaken for the latter. QE is the stance.
This is the implementation half of a rate decision — the mechanism that turns the committee's announced target into the rate that actually prevails.
