What it means
When a loan has a rate that can change, the contract spells out how the new rate will be worked out. The result of that calculation on each reset date is the reset rate, and it replaces the previous rate for the next period.
The standard recipe is the index plus the margin. The index, or reference rate, is a published benchmark that moves with the market, while the margin is a fixed spread agreed when the loan was signed, reflecting the lender's costs and the borrower's credit risk.
Adjustable-rate mortgages show the idea clearly. A loan might charge a low fixed rate for the first five years and then reset annually, and the first reset rate can be much higher than the starting rate, a jump that borrowers sometimes call payment shock.
Caps limit the damage. A periodic cap restricts how much the rate can rise at a single reset, and a lifetime cap sets the highest rate ever payable, while a floor sets the lowest, so the reset rate is often the lower of the fully indexed rate and the capped rate.
For businesses and investors, the reset rate has a direct effect on cash flow. Floating-rate notes, syndicated loans and commercial mortgages all have reset rates, and a treasury team models them in forecasts to see whether interest cover and loan covenants (promises made to the lender, such as minimum profit relative to interest) will still be met.
It helps to separate the reset rate from the reset date. The date is when the rate is recalculated, whereas the reset rate is the number that results, and both should be checked in the loan agreement before any forecast is built.
In practice
Real-world examples.
Example
A family has a mortgage that was fixed for five years and now resets annually. The lender writes to say the new reset rate is 1.5 percentage points higher, and the family reviews its budget and considers refinancing.
Example
A manufacturing company has a $20,000,000 syndicated loan with quarterly resets. Each quarter its treasurer calculates the reset rate from the published index and the 2.25% margin, and updates the forecast of interest expense.
Example
A pension fund holds floating-rate notes that reset every six months. When the index falls, the reset rate and coupon income both fall, so the fund's analyst adjusts the projected income from the holding.
Formula
Calculation
Fully indexed rate = index + margin; Reset rate = fully indexed rate, limited by the periodic cap, lifetime cap and floor.
Suppose a $300,000 adjustable-rate loan starts at 4.00%, with a periodic cap of 2 percentage points per reset. At the first reset the index is 6.50% and the margin is 2.75%, so the fully indexed rate = 6.50% + 2.75% = 9.25%. The periodic cap limits the reset rate to 4.00% + 2.00% = 6.00%. Using simple annual interest on the $300,000 balance, interest rises from 300,000 x 0.04 = $12,000 to 300,000 x 0.06 = $18,000, an increase of $6,000, whereas without the cap the interest would have been 300,000 x 0.0925 = $27,750.Case study
Seen in the real world.
Brookfield Medical Supplies is an illustrative, fictional distributor with a $9,000,000 term loan. The loan agreement set a margin of 2.50%, a floor of 3.00% and a lifetime cap of 8.00%.
When benchmark rates were low, the fully indexed rate fell below the floor, so the reset rate stayed at 3.00% and the company paid more than the market would have implied. Later, as benchmark rates climbed, the reset rate rose by stages and approached the cap, at which point the finance director realised the cap was her main protection.
She modelled the worst case of interest at the cap, which gave 9,000,000 x 0.08 = $720,000 a year, and confirmed that the business could pay this and still meet its covenants. The illustrative lesson is that the real reset rate depends on the full set of contract terms, not only the headline index.
Watch out
Common mistakes.
- Assuming the reset rate is the same as the index, when the margin, caps and floors all affect the final figure.
- Forgetting the floor, which can keep the rate higher than the market when benchmark rates fall.
- Looking only at the first reset, when later resets may bring further increases, especially if the cap applies each period.
Questions
People also ask.
How is the reset rate calculated?
It is normally the reference rate on the observation date plus the contractual margin, adjusted for any caps and floors.
Can the reset rate go down?
Yes, if the index falls the reset rate falls too, subject to any floor in the contract.
Where can I find my reset rate?
In the lender's notice before the reset date and in the loan agreement, which sets out the index, margin and limits.
