What once required long hours of manual work can now be completed within minutes with the help of AI tools. A young analyst at an investment bank previously spent nights working through spreadsheets, company filings, annual reports, and earnings transcripts before preparing presentations for senior bankers. Today, AI can summarise reports, analyse historical data, create valuation models, and even prepare draft insights almost instantly. This transformation is no longer just an idea for the future. Most major global banks are already investing billions of dollars in AI and automation. AI has quickly become an important part of the financial system because capital markets are naturally driven by data, speed, and analysis. Generative AI, in particular, has the potential to improve productivity and reduce operational costs across the industry. The impact of AI is most visible in trading activities. Quantitative and algorithmic trading already depend heavily on machine learning and predictive analytics. AI systems can process huge amounts of market data in real time, identify patterns, detect changes in sentiment, and react faster than any human trader. In high-frequency trading, speed is a major advantage, and AI performs exceptionally well in such an environment.
