Are global investors losing confidence in US government debt safety?
Core argument: The U.S. Treasury safety premium has compressed to near zero post-2022 and at points reversed, signaling that markets no longer treat Treasurys as unambiguously superior to credit-risk-adjusted corporate equivalents.
The top panel uses the credit risk-adjusted AAA-Treasury spread. We use the CDS to strip the default-risk compensation out of the corporate-bond yield. What remains is a clean estimate of the safety premium that investors pay for Treasurys over otherwise-equivalent corporate exposure. Post-2022, it has compressed toward zero, and at points, has reversed. The bottom panel uses the Treasury Premium, defined as the difference between the synthetic-dollar foreign sovereign yield and the US Treasury yield at the same maturity. The synthetic-dollar foreign yield is constructed by swapping the coupon payments on foreign G10 sovereign bonds into dollars using the foreign-exchange forward market. This eliminates currency risk over the life of the bond, so the resulting dollar cash-flow stream is directly comparable to a US Treasury yield of the same maturity. At longer maturities, global investors now seem to prefer the safety of foreign G10 bonds.
