In a landmark moment for financial technology, HSBC has unveiled results from a quantum computing trial that could redefine how Wall Street approaches bond trading. The bank’s experiment, conducted in partnership with IBM, demonstrated a 34% improvement in predicting bond trade execution—an edge that could translate into billions in competitive advantage.
Quantum Meets Wall Street

This is our Sputnik moment, said Philip Intallura, HSBC’s global head of quantum technologies. It’s the first time quantum computing has shown tangible value in live financial markets.
Why It Matters
Bond trading, especially in less liquid markets, hinges on predicting execution probability. A 34% boost in accuracy means traders can quote more confidently, manage risk better, and potentially unlock new revenue streams. For Wall Street firms competing on milliseconds and margins, quantum’s predictive power could be transformative.The Quantum Arms Race

According to McKinsey, quantum computing could generate $72 billion in annual revenue by 2035, up from $4 billion last year. Financial services are expected to be among the earliest beneficiaries, especially in areas like portfolio optimization, risk modeling, and fraud detection.
What’s Next
While quantum computers remain in their infancy, HSBC’s trial proves that even today’s noisy intermediate-scale quantum (NISQ) devices can deliver meaningful results. As hardware improves and algorithms mature, quantum could become a core pillar of financial infrastructure.For now, HSBC’s experiment is a wake-up call: the quantum future isn’t decades away—it’s already reshaping the foundations of Wall Street.
