An interest rate cap is a derivative in which the buyer receives payments at the end of each period in which the interest rate exceeds the agreed strike price. An example of a cap would be an agreement to receive a payment for each month the LIBOR rate exceeds 2.5%.
The Black model (sometimes known as the Black-76 model) is a variant of the Black–Scholes option pricing model. Its primary applications are for pricing options on future contracts, bond options, interest rate cap and floors, and swaptions. It was first presented in a paper written by Fischer Black in 1976.
The researcher [2] decided that to assess the appropriateness of an interest rate cap as a policy instrument (or whether other approaches would be more likely to achieve the desired outcomes of government) it was vital to consider what exactly makes up the interest rate and how banks and MFIs are able to justify rates that might be considered excessive.
(Some analysts use "realized volatility", i.e. of the rates applicable historically for the time-step; to be market-consistent, analysts generally prefer to use current interest rate cap prices, and the implied volatility for the Black-76-prices of each component caplet; see Interest rate cap § Implied Volatilities.)
A periodic rate cap: Limits how much the interest rate can change from one year to the next. A lifetime rate cap: Limits how much the interest rate can rise over the life of the loan.
repeat until the discounted value at the first node in the tree equals the zero-price corresponding to the given spot interest rate for the i-th time-step. Step 2. Once solved, retain these known short rates, and proceed to the next time-step (i.e. input spot-rate), "growing" the tree until it incorporates the full input yield-curve.
The Fed's rate hikes sent interest expense for S&P 500 companies soaring. The expense rose 64.3% in the second quarter to $37.21 per share, the highest levels since the second quarter of 2008.
