# Central Bank ⎊ Definition **Published:** 2026-03-09 **Author:** Greeks.live **Categories:** Definition --- ## Central Bank A central bank is the institution responsible for overseeing a nation's monetary system and currency. By setting interest rates and implementing monetary policy, it directly influences the cost of borrowing and the availability of credit in the economy. In the derivatives world, the central bank is the "setter of the price of time." Its decisions dictate the risk-free rate, which is the foundational input for almost every pricing model. Traders must anticipate central bank actions to manage their risk effectively. It is the single most important institution in the financial ecosystem, acting as the ultimate backstop and trendsetter for all markets. - [Matching Engine](https://term.greeks.live/definition/matching-engine/) - [Interest Rates](https://term.greeks.live/definition/interest-rates/) - [Fee Structure](https://term.greeks.live/definition/fee-structure/) - [Normal Distribution](https://term.greeks.live/definition/normal-distribution/) - [Cost Reduction](https://term.greeks.live/definition/cost-reduction/) - [Trading Expenses](https://term.greeks.live/definition/trading-expenses/) - [Index Price](https://term.greeks.live/definition/index-price/) - [Long Term Investing](https://term.greeks.live/definition/long-term-investing/) ## Discover More ### [Position Sizing Strategies](https://term.greeks.live/term/position-sizing-strategies/) ![A detailed close-up shows a complex circular structure with multiple concentric layers and interlocking segments.
