An upper limit on the interest rate on a floating-rate note (FRN) or an adjustable-rate mortgage (ARM). Also, an OTC derivatives contract consisting of a series of European interest rate call options; used to protect an issuer of floating-rate debt from interest rate increases. Each individual call option within the cap is called a caplet. Opposite of a floor.


1. Informal for market capitalization.

2. In a floating-rate note or an adjustable-rate mortgage (ARM), the highest possible interest rate. For example, if one has an adjustable-rate mortgage on a house, the interest rate fluctuates periodically. However, if the homeowner has a cap on the interest rate, there is a guarantee that it will never rise above a certain percent, no matter what the ARM formula would otherwise dictate. A cap is designed to protect the person or company making the interest payments. See also: Floor, Collar.

A cap is a ceiling, or the highest level to which something can go.

For example, an interest rate cap limits the amount by which an interest rate can be increased over a specific period of time. A typical cap on an adjustable rate mortgage (ARM) limits interest rate increases to two percentage points annually and six percentage points over the term of the loan.

In a different example, the cap on your annual contribution to an individual retirement account (IRA) is $4,000 for 2006 and 2007 and $5,000 in 2008, provided you have earned at least that much. If you're 50 or older, you can make an additional catch-up contribution of $1,000 each year.




A ceiling on the adjustments that can be made in the payments or interest rate of an adjustable-rate loan.


Same as Float-Down.
