    Global Macro Research: Modelling the persistence of US inflation

    Modelling the persistence of US inflation

    19 October 2023 Global macro

    Executive summary

    The housing market indicates stable but above-target CPI for at least two years

    With US inflation at the highest levels since the 1980s, investors are worried about how long inflation will remain elevated. We attempted to answer this question – not by looking at supply chains, energy prices or goods and services – but by focusing on what has historically been the most persistent and long-term driver of CPI: rental inflation. 

    Our results show that inflation will remain stable but well above target for the next two years. Our central case indicates CPI will start to converge on the Fed’s target by the end of 2023, but it could take longer.

    The Fed potentially has limited ability to return CPI to its target in the medium term

    If house prices continue to rise at a strong pace, we expect this to drag rents up. If the Fed instead raises rates enough to contain the housing market, it will likely result in higher mortgage rates, which would potentially drag rents up instead.
