Global borrowing costs hit fresh highs on oil, AI and inflation

Long-term borrowing costs in major global economies are surging to fresh highs, fueled by a confluence of factors including persistent inflation fears, escalating government debt levels, and substantial investments in Artificial Intelligence (AI). The interest rate on 30-year US debt climbed to 5.33% on Tuesday, marking its highest point since June 2007. Similarly, UK long-term debt reached 5.85%, with comparable increases seen in Germany and Japan.

These rising interest rates on bonds, known as yields, have a direct impact on the cost of borrowing for consumers, affecting rates for mortgages, car loans, and credit cards. A primary driver behind the recent spike in bond yields is the escalating price of oil. Investors are increasingly concerned that inflation could re-accelerate, potentially prompting central banks to raise interest rates further to curb price increases.

The price of Brent crude, the global oil benchmark, surpassed $90 per barrel following heightened tensions in the Middle East. President Donald Trump's threat to bomb Oman if it interfered with talks to reopen the Strait of Hormuz, a vital passage for global oil supply, has exacerbated these concerns. The potential closure of this strait, which has already faced disruptions, contributes to higher oil prices and, consequently, can lead to broader price increases across goods and services as companies pass on increased transportation costs.

John Canavan, lead analyst at Oxford Economics, explained that the inflation risk from higher oil prices, coupled with high government debt and the uncertainty surrounding AI investments, are all contributing to the elevated borrowing costs. He warned that this could translate into higher mortgage and car loan rates for consumers. Furthermore, higher yields mean companies may face increased borrowing expenses, which could also be passed on to customers, adding to the overall inflationary pressure and potentially slowing economic growth in the longer term. Bond investors typically demand higher returns when inflation is high or expected to rise.
