In fact, if one takes a longer view of real interest rates in the US, calculated by subtracting the previous year’s inflation from the nominal government bond yield, one finds that, while they are much lower than 20 years ago, they are not low by historical standards. The average real long-term government interest rate in 1891-1979 – a period ending just before Volcker oversaw soaring growth in borrowing costs – was a mere 1.25%, which is very close to the real long-term interest rate today.
