The new paper "Are Government Bonds Safe in time of war and Pandemic?" examines the behavior of bonds during periods of war and other non-financialcrises. Not surprisingly, there is a difference. Wars are associated with sharp declines in real returns and with returns that lag growth. The reasons are clear. There is elevated surprise inflation during a war, and governments impose financial repression, which creates a wedge between real returns and grwoth/. The bondholders bear the cost of war, even relative to risky assets. That is not the case during a financial crisis or a pandemic. Pandemics are similar to war in that they entail labor supply constraints, trade restrictions, a surge in spending, and significant increases in central bank balance sheets.
All risks are not equal. Bonds are not always safe. The assumption that government bodies are always safe will be costly. Now, the war scenario may be easy to adapt to, but the real question is whether there are other government or geopolitical-induced events that are adverse for bonds. That is the real current question. When is the environment not safe for bonds?
