Emerging Market Economy (EME) banks have historically had limited access to derivatives due to less developed financial markets, higher costs, and regulatory constraints. Instead, they typically focus on repricing gap management, aligning the timing of asset and liability repricing to mitigate interest rate risk (IRR). This approach is simpler and more feasible in the context of their financial systems and market environments.

C is incorrect: While some speculation might occur, the primary use of derivatives for banks is hedging, not speculation.
D is incorrect: EME banks are not entirely prohibited from using derivatives, but their usage has historically been limited.
