Which advanced economy shows the most unusual long-end bond market strain?
Core argument: Japan stands out among G10 economies on a measure of long-end yield curve distortion, defined as the gap between the 10y10y forward rate and the 10-year yield, demeaned and divided by its historical standard deviation.
The blue lines are my proxy for how “broken” yield curves are at the long end. This is the difference between the 10y10y forward [which is what markets price for the 10-year yield in 10 years’ time] and 10-year yield. I demean this difference and divide it by its historical standard deviation. The resulting z-score measures how unusual the slope of the yield curve is at the long end relative to history. The black line in each chart is the median across all G10 z-scores. The gray shaded area is a two standard deviation confidence interval around the black line. If you’re outside this area, something very worrying is going on. Japan sticks out like a sore thumb on this metric.
