# Interest Rate Parity ⎊ Definition **Published:** 2025-12-14 **Author:** Greeks.live **Categories:** Definition --- ## Interest Rate Parity Interest rate parity is a theory in international finance that describes the relationship between interest rates and currency exchange rates. It posits that the difference in interest rates between two countries should equal the expected change in exchange rates between their currencies. In the crypto derivatives market, this concept is adapted to explain why funding rates exist for perpetual futures. It suggests that the cost of borrowing capital to leverage a position must be reflected in the price of the derivative. If interest rate parity did not hold, there would be massive arbitrage opportunities that would quickly correct the imbalance. This theory provides the mathematical foundation for understanding how capital flows between different crypto-assets and stablecoins. - [Interest Rate Differential](https://term.greeks.live/definition/interest-rate-differential/) - [Interest Rate Arbitrage](https://term.greeks.live/definition/interest-rate-arbitrage/) - [Federal Funds Rate](https://term.greeks.live/definition/federal-funds-rate/) - [Carry Trade](https://term.greeks.live/definition/carry-trade/) - [Interest Rate Volatility](https://term.greeks.live/definition/interest-rate-volatility/) - [Interest Rate Swaps](https://term.greeks.live/definition/interest-rate-swaps/) - [Interest Rate Sensitivity](https://term.greeks.live/definition/interest-rate-sensitivity/) - [Duration](https://term.greeks.live/definition/duration/) ## Glossary ### [Open Interest Skew](https://term.greeks.live/area/open-interest-skew/) Definition ⎊ Open interest skew refers to the uneven distribution of open options contracts across different strike prices for a given expiry. ### [Rho Interest Rate Sensitivity](https://term.greeks.live/area/rho-interest-rate-sensitivity/) Calculation ⎊ Rho Interest Rate Sensitivity, within cryptocurrency options and financial derivatives, quantifies the sensitivity of an option’s theoretical value to a one percent change in prevailing interest rates. ### [Interest Rate Curve Oracles](https://term.greeks.live/area/interest-rate-curve-oracles/) Algorithm ⎊ Interest Rate Curve Oracles represent a computational methodology for deriving and disseminating forward rate expectations within decentralized finance. ### [Interest Rate Swap](https://term.greeks.live/area/interest-rate-swap/) Definition ⎊ An interest rate swap in digital asset markets functions as a derivative contract where two counterparties exchange periodic cash flow streams based on a notional principal amount. ### [Theoretical Equilibrium](https://term.greeks.live/area/theoretical-equilibrium/) Context ⎊ Theoretical equilibrium, within the domains of cryptocurrency, options trading, and financial derivatives, represents a state where market forces—supply and demand—are balanced, resulting in a stable price or rate. ### [Cross-Chain Interoperability](https://term.greeks.live/area/cross-chain-interoperability/) Interoperability ⎊ Cross-chain interoperability represents the capability for distinct blockchain networks to communicate, share data, and transfer assets seamlessly. ### [Risk-Free Rate Parity](https://term.greeks.live/area/risk-free-rate-parity/) Arbitrage ⎊ Risk-Free Rate Parity, within cryptocurrency markets, represents an extension of covered interest rate parity, seeking to exploit discrepancies in pricing between spot and derivative markets, specifically perpetual swaps and the underlying asset, adjusted for funding costs. ### [Annualized Funding Rate Yield](https://term.greeks.live/area/annualized-funding-rate-yield/) Rate ⎊ The annualized funding rate yield represents the extrapolated return generated from collecting or paying the periodic funding rate in a perpetual futures contract market. ### [Kinked Interest Rate Curves](https://term.greeks.live/area/kinked-interest-rate-curves/) Definition ⎊ Kinked interest rate curves represent a non-linear term structure in cryptocurrency derivatives where the forward rate expectations shift abruptly at specific maturity points. ### [Capital Parity](https://term.greeks.live/area/capital-parity/) Capital ⎊ Within the context of cryptocurrency derivatives, capital parity signifies a theoretical equilibrium between the market capitalization of an underlying cryptocurrency and the aggregate value of associated derivative instruments, particularly options. ## Discover More ### [Funding Rate Manipulation](https://term.greeks.live/term/funding-rate-manipulation/) ![This abstract rendering illustrates the intricate mechanics of a DeFi derivatives protocol.
