Quantum computing has emerged as a transformative technology that holds the potential to revolutionize various industries, including banking. As quantum computers continue to advance, they pose significant risks to existing encryption methods that secure sensitive financial data. Traditional cryptographic systems, such as RSA and elliptic curve cryptography (ECC), are foundational to modern banking security; however, these methods rely on mathematical problems that quantum algorithms, notably Shor's Algorithm, could solve exponentially faster than classical computers. This paper explores the impact of quantum computing on banking encryption systems and discusses the urgent need for post-quantum cryptography. We examine the vulnerabilities of current banking encryption protocols, the status of quantum-safe cryptographic algorithms, and strategies for implementing quantum-resistant systems in the financial sector. The transition to post-quantum security requires collaborative efforts among financial institutions, regulatory bodies, and quantum computing researchers to ensure a secure and efficient implementation of future-proof encryption standards. This paper emphasizes the importance of early adoption and the proactive steps required to safeguard banking systems against the imminent quantum threat
