How much do central bank balance sheet reductions raise long-term yields?
Core argument: A rule of thumb derived from a range of studies holds that balance sheet reduction equal to 1% of GDP is associated with a roughly 2bp rise in 10-year Treasury yields.
We continue to expect the Fed’s balance sheet runoff to have modest effects on interest rates, broader financial conditions, growth, and inflation. Our rule of thumb derived from a range of studies is that 1% of GDP of balance sheet reduction is associated with a roughly 2bp rise in 10-year Treasury yields. In total, our projections for runoff imply that balance sheet normalization will have exerted around 20bp worth of upward pressure on 10-year yields since runoff started. Together with our rule of thumb that a 25bp boost to 10-year term premia from balance sheet reduction has roughly the same impact on financial conditions and growth as a 25bp rate hike, this implies that the total runoff process should have the effect of a little under one rate hike.
