From the economist as to why bond prices not dropping13 Jan 2025 10:58
Instead, the big change concerns greater uncertainty in investors’ expectations. This could be pushing up the “term premium”—the extra yield investors charge on long-term government bonds, over and above that attributable to the changes in the central bank’s policy rate that are already expected. The term premium compensates bondholders for the risk that bond prices fall sharply; say, if unexpected inflation forces central banks to aggressively raise rates. Sure enough, increases in the premium on ten-year Treasury yields account for nearly all of the rise in these yields since early December (see chart 2).
It is easy to see why uncertainty has spread. Will Donald Trump deport millions of people? Nobody knows. But if he succeeds inflation could jump as employers lose workers. The story is similar for tariffs, which would also increase prices. At the same time, potential Chinese counter-measures in a trade war, such as a devaluation of the yuan, could prompt a global deflationary shock.
Investors are also unsure about economic growth. The dominant narrative veers from one extreme to the other. Some investors worry about the damaging effects of deglobalisation and a slowing Chinese economy. But there are optimists, too, including those who believe that Mr Trump’s mooted economic-policy reforms, including slashing red tape and cutting taxes on everything from tips to social security, will spur growth. Maybe an ai-powered productivity surge is around the corner. The effect of all these contradictory scenarios is to raise the term premium on government bonds even more.
Fiscal policy is not helping matters. This year g7 governments are expected to run an average budget deficit of 6% of gdp—unusually high considering that unemployment is low and economies are growing well enough. Funding these deficits means issuing fresh bonds. America is expected to issue about $2trn-worth (equivalent to 7% of gdp) this year, after accounting for redemptions. Euro-zone governments will collectively issue perhaps €500bn ($513bn, or about 3% of gdp).
