Bank of America interest rates strategist Mark Cabana has warned that global interest rate increases could lead to significant financial instability. These concerns emerge as central banks, particularly in the United States, maintain high benchmark rates that impact international investments.
Why it matters
Rising borrowing costs driven by low productivity and geopolitical tensions pose a threat to global financial health. The interconnectedness of world markets means that shifts in United States monetary policy carry direct risks for foreign asset portfolios.
The United States Federal Reserve previously lifted interest rates from near zero to above 4 percent during 2022, eventually exceeding 5 percent by mid-2023. Benchmark rates currently fluctuate between 3.75 percent and 4 percent.
