Long‐term rates: lower for longer

With the Federal Reserve and other central banks likely to start raising interest rates from next year, the focus is now on how high interest rates might ultimately go. Long‐term analysis of the path of interest rates in the world's main economies suggests that interest rates tend over time to gravitate towards a level reflecting long‐run growth and inflation. But there is scope for real interest rates to depart substantially from growth for lengthy periods of time. Based on our long‐run forecasts for growth and inflation we take the view that long‐term interest rates are likely to settle in at levels a bit lower than their recent historic averages. Structural changes in the world economy and vulnerabilities in the advanced economies are also likely to slow the process by which long‐term rates rise from current levels to their steady state positions. OE forecasts for long‐term rates in the major economies are generally lower at the 1‐year and long‐term horizons than consensus.
