Are higher long-term Treasury yields driven by weaker demand, not inflation expectations?
Core argument: The rise in US 10- and 30-year Treasury yields is not reflected in higher long-term inflation expectations, as measured by spreads between inflation-indexed and non-indexed Treasury bonds.
It would be easy to explain what is going on with long-dated US treasuries if it were simply the case that investors were finally waking up to the risk of higher inflation — or least periodic burst of it — in a world of deglobalization and patently unsustainable budget deficits. In that case, most of the rise of ten and thirty-year rates would be reflected in higher LONG-TERM inflation expectations. Yet, that does not seem to be the case, at least using the spreads between inflation indexed and non-indexed Treasury bonds. At first glance anyway — and I expect to look more deeply in due time and report on these pages — it really is a shift in demand away from long-dated US debt, a shift that will reinforce the pain of higher long-term real interest rates. The rise over the past couple years has come as no surprise to those of us who think one has to look very long-time periods to distinguish between a genuinely permanent shock as opposed to say, a long-lasting but ultimately temporary shock such as the one that occurred in the wake of the 2008-09 global financial crisis. I never bought into the secular stagnation thesis.
