so how does the FED currently targets an interest rate range between 4.25%-4.50%? let's consolidate everything with an example using current, real-world data

SRF has been introduced in 2021, due to occasional spikes of short-term funding rates outside of the corridor this is because banks avoid using the discount rate - as that is often seen as a sign of financial distress by the broader market

thus, Standing Repo Facility (SRF) further reinforces the upper part of the target interest rate corridor in other words, it strengthens the cap on short-term interest rates

Standing Repo Facility (SRF) allows banks & other financial institutions to do collateral-backed loans from the FED overnight the institution provides high quality collateral (e.g. treasury bond) and gets a loan against it - at the set rate

it't called discount window for historical reasons discounting means buying treasuries at a slightly lower price - i.e. at a discount window comes from the fact that these were sold at counter/teller windows at the bank

the discount rate is set higher or at the typical market rates to disincentivize its use it's really meant to serve as an emergency lending source - only when other financing routes are exhausted: regular interbank markets, wholesale markets and SRF among others

Discount Rate is the rate at which the FED lends directly to banks through its discount window think of it as an emergency lending facility which the banks can use whenever they need funds since banks can always get a loan at that rate - it caps the short-term interest rates

the majority of liquidity is actually created in wholesale short-term debt markets ON RRP addresses exactly that sector, thus setting the lower bound of the target interest rate corridor for the broader financial sector

ON RRP further reinforces the the floor for the market-wide interest rates since it's accessible to a broader set of financial institutions - not only banks. those now also have little incentive to lend below the ON RRP rate

Overnight Reverse Repo Rate (ON RRP) defines the rate at financial institutions can lend money overnight to the FED in return the FED provides treasury bonds as a collateral ON RRP is accessible to both banks & non-banks (e.g. money market funds)

since banks can always deposit cash into their reserve account account at the FED and earn the IORB rate they have little incentive to lend at rates below IORB effectively, this sets the floor (lower bound of the corridor) for interest rates for banks

Interest on Reserve Balances (IORB) is the rate FED pays banks on their excess reserves commercial banks have reserve accounts at the FED. regulations define the minimum amounts - any excess earns the IORB interest rate set by the FED

the 4 key interest rates set by the FED are: 1️⃣ Overnight Reverse Repo Rate (ON RRP) 2️⃣ Interest on Reserve Balances (IORB) 3️⃣ Discount Rate - also known as Lending Rate 4️⃣ Standing Repo Facility (SRF) we'l cover them in this order in follow-up posts

now let's understand each one of the 4 key rates set by the federal reserve to keep the market rates within the target range namely, what each one of those rates represents and how together they act as ceiling or floor for the interest rate corridor

so when banks and other financial institutions need to lend capital - they can do it at a rate within the target range of course, their balance sheet capacity must allow for that - but that's another topic which I already covered in some detail in my other posts😁

now you should have a clear mental model of how the Federal Reserve sets the interest rates in the market a target range is defined, and then several different interest rates are set explicitly to steer the real interest rate into that target range

think of these 4 rates as defining a corridor with an upper and a lower bound - currently 4.25% and 4.50% the average market interest rate will sit somewhere in between

in the Federal Open Market Committee Meetings (FOMC), the Federal Reserve sets a target range - currently 4.25%–4.50%, and then it uses the ON RRP, IORB, discount rate and SRF to steer the average rate in the market

together, ON RRP, IORB, discount rate and SRF define an interest rate corridor, composed by: 1️⃣ lower bound (floor) - the lowest possible interest rate 2️⃣ upper bound (ceiling) - the highest possible interest rate the other market rates fluctuate between this floor and ceiling

the federal reserve does not set a single interest rate instead, the FED sets a target interest rate range (the federal funds target range) alongside 4 main explicit interest rates

how can the FED even set market-wide rates? 🤔 after all - there is no single rate that the whole market unanimously uses different types of lending have different rates in the market, as it's a (somewhat) open market

how does the Federal Reserve set interest rates? some think that they define a single rate - namely the overnight lending rate - i.e. the rate at which the banks lend to each other overnight but that's not the case ❌

i'll be explaining the details of how the Federal Reserve achieves their fed funds target rate in the next posts i'll be quoting them in sequence - so you can follow the trail of quoted posts and read them like a thread/article starting with the next post. let's dive in! 🚀

User

the FED left the interest rates unchanged - at the 4.25%-4.50% target while they communicated that previously - so it's no surprise - understanding how they achieve that level of short-term rates means understanding the important central bank in the world 🏦 so i'll explain it!
