Global economy braces for danger as interest rates rise

The global economy faces growing risks as borrowing costs rise, with the Bank of America warning that the threshold for dangerous interest rates is near. Factors like lower productivity, excess demand, AI advancements, and geopolitical tensions, including the Iran conflict, are driving up debt costs. While current interest rate hikes haven't severely impacted stock markets or property values, Mark Cabana, head of interest rates strategy at Bank of America, cautions that the situation is approaching a critical point.

U.S. benchmark interest rates recently increased by a quarter-percentage-point, reaching a range of 3.75% to 4%. Central banks are struggling to balance taming economic demand without causing financial instability. Cabana notes recent sell-offs in the U.S. bond market, pushing yields to levels unseen in decades, but asserts this hasn't drastically affected asset prices. He predicts further rate hikes, though current levels aren't yet restrictive enough to slow growth significantly.

Goldman Sachs expects the next interest rate hike in December, potentially raising the federal fund target to 4% to 4.25%. Cabana warns that rates inching into the high 4s or mid 5s could become hazardous. Australia is already experiencing a cooling housing market and declining share prices, with its 10-year bond yield hitting the highest level since 2011. Cabana recently met with Australian superannuation sector figures to discuss these concerns, highlighting the impact on working Australians' retirement savings.

Some analysts, like Anna Wu, an investment strategist at VanEck, argue that the current AI-driven investment boom could absorb short-term financial shocks. She distinguishes present conditions from past rate hikes, emphasizing stronger growth expectations over rampant inflation. However, financial institutions, including the Reserve Bank of Australia, fear that unmanageable inflation expectations could necessitate drastic economic measures to restore balance.
