It expects five million will see their monthly repayments rise, typically by £45, by 2028. That is up from four million predicted before the Middle East conflict.\n\nRate rise fears have abated since Iran and the US signed a deal to end the conflict.\n\nBank of England Governor Andrew Bailey has warned of risks associated with the AI boom\n\nBut the Bank cautioned that other risks to the financial system remained and were in some cases higher – notably those linked to AI.\n\nHaving already highlighted the risks of an AI-related stock market bubble, the Bank said that since the end of last year valuations had become even more stretched.\n\nAnd there has been a ‘significant increase’ in leverage by hedge funds in stock markets – the practice of borrowing money using shares as collateral.\n\nOrdinary savers have also piled in via exchange-traded funds (ETFs).\n\nMeanwhile, AI firms themselves have also stepped up borrowing to fund huge infrastructure investments. Yet earnings growth remains ‘highly uncertain’ and depends on the continued progress on these investments and the adoption of AI across the economy, the Bank noted.\n\n‘A reassessment of these prospects could trigger a fall in equity prices,’ it said – sparking major knock-on consequences.\n\nAnd there was a stark warning over the need for banks to guard against the risks of ‘frontier AI’ – the latest cutting-edge technology that could add to risks of cyber attack.\n\n‘Recent rapid advances in frontier AI capabilities have increased financial stability risks related to cyber and operational resilience,’ the Bank said.\n\nThese may make ‘faster, larger-scale and more correlated disruption more credible’, it said.\n\n‘The issue is not that cyber risk is new, but that frontier AI may materially change its speed, scale and economics,’ the report said.\n\nAlongside the report, the Bank announced plans to ease some of the post-2007 rules governing the amount of capital lenders must hold to guard against a financial shock.\n\nRequirements were scaled back to bring the UK regulations more into line with global peers and will particularly benefit domestically-focused lenders such as Natwest, Lloyds, Nationwide and Santander UK.\n\n## DIY INVESTING PLATFORMS\n\nAffiliate links: If you take out a product This is Money may earn a commission.
