Similarly, an interest rate floor is a derivative contract by which the buyer receives payments at the end of each period during which the interest rate is below the agreed exercise price. Although price caps are strongly identified with UK distribution companies, these guidelines have been introduced elsewhere, including the United States. For example, in the United States, telephone operators have been subject to a price cap for some time, although it has been largely replaced by interest rate regulation. Additional costs can be borne by companies as long as they wish to maintain compliance with cap price regulations. This may include time and management resources to ensure that the company`s rates and prices are within the range indicated. The existence of a price cap may force utilities to find ways to reduce costs in order to improve their profit margins. A positive case could be advanced for the efficiency gains that regulations promote. Price-fixing caps for the sector mean that companies must focus on operating their least disrupted business at the lowest possible price, in order to make the greatest profit. A price cap is a form of economic regulation that is generally specific to the UK supply industry.
The price cap does not limit the price that the service provider can charge. The ceiling is based on several economic factors such as the capped price index, expected efficiency savings and inflation. Price caps are contrary to performance rules and income rules to other forms of price and profit controls used in the UK. All UK private networks must now meet the price cap. The interest rate ceiling can be analysed as a series of European call options, called caplets, that exist for each period during which the Cap Agreement exists. To exercise a ceiling, the buyer is generally not required to notify the seller, as the ceiling is exercised automatically when the interest rate is higher than the strike (rate).  Note that this automatic exercise feature is different from most other options. Each caplet is set in cash at the end of the period to which it relates.  A price cap may have the side effect of discouraging investment by distribution companies, such as . B investments in infrastructure companies. Companies that limit prices could also reduce services if they tried to control costs.
This could lead to an erosion of quality and service by public services. The fact that such measures may encourage new entrants to enter the market is a deterrent to reduce service too much and reduce costs. There may also be minimum requirements imposed by regulators to prevent businesses from eliminating essential services. For example, a price floor could be introduced to deter companies from reducing their tariffs to anti-competitive levels that would be significantly below competition. The purchaser of a ceiling will continue to benefit from an increase in interest rates above the exercise price, making the cap a popular means of hedging a variable rate loan for an issuer.  An interest rate cap is a derivative by which the buyer receives payments at the end of each period during which the interest rate is higher than the agreed exercise price.
