Inflation swaps are financial contracts between two parties, whereby one agrees to pay an amount based on changes in an agreed-upon inflation rate and the other agrees to receive that same amount. The fix rate payment is mutually agreed upon and is based on the expected inflation rate over the course of the swap. These swaps are considered derivatives instruments, because their value is based on the value of the underlying asset, in this case the inflation rate.

Inflation swaps are used to hedge against inflation risk. By entering into this contract, the two parties can manage their exposure to inflation risk. For example, if inflation is expected to rise, the party receiving the fixed payment would be able to secure their income, while the party paying the fixed payment would benefit from higher inflation.

The inflation swap can also help investors to forecast a break-even inflation rate. An investor will analyze the value of the swap and use it as a reference point to construct a portfolio that is suitable for their needs. By having a better understanding of their break-even rate, an investor can protect their profits from any unforeseen inflation risk.

Inflation swaps are also used to take advantage of changes in inflation. If a party believes inflation will be higher than expected, they can purchase an inflation swap to benefit from the potential change. This is especially useful for speculative trading, as traders can use the swap to place a bet on future inflation rate changes.

In short, an inflation swap is a financial contract between two parties, in which the payer pays an amount to the receiver in exchange for a fixed payment, based on changes in an agreed-upon inflation rate. This contract is used to manage and hedge the risk of inflation and to take advantage of changes in inflation rate. It helps investors to forecast a break-even inflation rate and to construct portfolios accordingly. Investors and traders can also use the swap to place a bet on future inflation changes.
