SynopsisGlobal markets are optimistic about AI and easing inflation, but David Roche warns of deeper structural risks. He believes the AI investment boom is unsustainable and the recent oil deal, while lowering prices, strengthens Iran's strategic position. Roche anticipates inflation will remain contained due to falling oil prices and the Fed's commitment to price stability.AgenciesCommenting on the outlook for the technology sector, Roche said his concern is not with AI itself but with the unprecedented level of capital being committed to it.Global markets continue to shrug off macroeconomic uncertainties, buoyed by optimism surrounding artificial intelligence and easing concerns over inflation. But David Roche from Quantum Strategy believes investors may be overlooking deeper structural risks that could eventually reshape financial markets.Speaking to ET Now, Roche discussed the US Federal Reserve's latest stance, the AI investment boom, geopolitical developments involving Iran, and the outlook for global technology spending.Fed's inflation fight supports market confidenceRoche said the Federal Reserve's commitment to fighting inflation has strengthened confidence in the US dollar while keeping long-term inflation expectations in check."People assume that the Fed will continue to fulfil its inflation mandate ahead of anything else. Therefore, interest rates... will not be cut, at least not at the moment... That helps markets because it gives confidence in the dollar."AI Boom May Be UnsustainableWhile acknowledging AI's transformative potential, Roche argued that the scale of investment has become excessive and could eventually hurt markets."AI is... a bubble. Not because it is not a good product, but because the amount of money being poured into it is not rational and will not be remunerated by profits."He warned that a correction in AI investments could have far-reaching consequences for both markets and the broader economy.Oil Relief, But Strategic Risks RemainRoche said markets are welcoming the resumption of oil flows as lower crude prices would ease inflationary pressures."Traders love the oil flowing. The oil prices are going to come down, lower inflation, less increases in interest rates."However, he sharply criticised the broader agreement."The MoU is a bad, bad, bad deal. It puts Iran in charge of the Gulf... and essentially puts the Iranians... back in the dollar flow."Trump's Priority Is Lower Oil PricesAsked whether the agreement is effectively an exit strategy for the United States, Roche answered in the affirmative."Trump needs this deal because he needs lower oil prices... The Iranians... need the dollars. The reason the deal will hold is because the two parties have a common interest."He added that the agreement strengthens Iran's strategic position despite helping stabilise oil markets.Inflation Likely to Stay ContainedRoche believes the recent rise in inflation is likely to prove temporary as oil prices ease and the Federal Reserve remains focused on price stability."The reason for the oil prices to go up has now been removed. There will be more oil and lower prices... The Fed made it quite clear that they were going to fight any inflation."Technology Spending Faces a Reality CheckCommenting on the outlook for the technology sector, Roche said his concern is not with AI itself but with the unprecedented level of capital being committed to it."What I see on IT is a great product being financed with complete excesses... We have over a trillion dollars being dedicated to IT."He cautioned that the economics behind these investments may ultimately disappoint investors."My concern about IT is not that it is not a good product. It is a great product... Nobody is going to pay the amount of money that would have to be paid to actually pay back this capital."Read More News on(What's moving Sensex and Nifty Track latest market news, stock tips, Budget 2025, Share Market on Budget 2025 and expert advice, on ETMarkets.
