Floating rate note

From Wikipedia, the free encyclopedia

Floating rate notes (FRNs) are bonds that have a variable coupon, equal to a money market reference rate, like LIBOR or federal funds rate, plus a quoted spread (also known as quoted margin). The spread is a rate that remains constant. Almost all FRNs have quarterly coupons, i.e. they pay out interest every three months. At the beginning of each coupon period, the coupon is calculated by taking the fixing of the reference rate for that day and adding the spread.[1][2][3] A typical coupon would look like 3 months USD LIBOR +0.20%.

In the United States, government sponsored enterprises (GSEs) such as the Federal Home Loan Banks, the Federal National Mortgage Association (Fannie Mae) and the Federal Home Loan Mortgage Corporation (Freddie Mac) are important issuers.[3] In Europe, the main issuers are banks.[citation needed]


Some FRNs have special features such as maximum or minimum coupons, called "capped FRNs" and "floored FRNs". Those with both minimum and maximum coupons are called "collared FRNs".

"Perpetual FRNs" are another form of FRNs that are also called irredeemable or unrated FRNs and are akin to a form of capital.

FRNs can also be obtained synthetically by the combination of a fixed rate bond and an interest rate swap. This combination is known as an asset swap.

A deleveraged floating-rate note is one bearing a coupon that is the product of the index and a leverage factor, where the leverage factor is between zero and one. A deleveraged floater, which gives the investor decreased exposure to the underlying index, can be replicated by buying a pure FRN and entering into a swap to pay floating and receive fixed, on a notional amount of less than the face value of the FRN.[4]

Deleveraged FRN = long pure FRN + short (1 - leverage factor) x swap

A leveraged or super floater gives the investor increased exposure to an underlying index: the leverage factor is always greater than one. Leveraged floaters also require a floor, since the coupon rate can never be negative.

Leveraged FRN = long pure FRN + long (leverage factor - 1) x swap + long (leverage factor) x floor


FRNs carry little interest rate risk.[3] An FRN has a duration close to zero, and its price shows very low sensitivity to changes in market rates. When market rates rise, the expected coupons of the FRN increase in line with the increase in forward rates, which means its price remains constant. Thus, FRNs differ from fixed rate bonds, whose prices decline when market rates rise. As FRNs are almost immune to interest rate risk, they are considered[by whom?] conservative investments for investors who believe market rates will increase. The risk that remains is credit risk.


Securities dealers make markets in FRNs. They are traded over-the-counter, instead of on a stock exchange. In Europe, most FRNs are liquid, as the biggest investors are banks. In the U.S., FRNs are mostly held to maturity, so the markets aren't as liquid. In the wholesale markets, FRNs are typically quoted as a spread over the reference rate.[5]


Suppose a new 5 year FRN pays a coupon of 3 months LIBOR +0.20%, and is issued at par (100.00). If the perception of the credit-worthiness of the issuer goes down, investors will demand a higher interest rate, say LIBOR +0.25%. If a trade is agreed, the price is calculated. In this example, LIBOR +0.25% would be roughly equivalent to a price of 99.75. This can be calculated as par, minus the difference between the coupon and the price that was agreed (0.05%), multiplied by the maturity (5 year).

Simple margin

The simple margin is a measure of the effective spread of a FRN that is not traded at par. If the FRN trades at par, the simple margin will equal the quoted spread.

To calculate the simple margin, first compute the sum of the quoted spread of the FRN and the capital gain (or loss) a investor will earn if the FRN is held to maturity:

Second, adjust the above for the fact that the FRN is bought at a discount or premium to the nominal value:

A more complex measure of the effective spread is a discount margin, which takes into account the "time value of money" of the FRN cash flows. The formula for the calculation of the discount margin is more complex and its calculation generally requires a financial calculator or a computer.
