One of the big downside risks for the US in its current trade war with China concerns the fact that Beijing owns $1.18 tn of US Treasuries. They also own billions of US mortgage bonds. The big question is whether they will decide to use such ownership as a weapon against the US. For instance, if they sold off large quantities of the bonds, it could send US yields spiking. However, it seems unlikely they would do say for a number of reasons. Firstly, it would hurt the value of their own holdings and all their other Dollar-denominated assets, and it would engender a lot more punitive action from the US. Some consider it the economic equivalent of “mutually assured destruction”.
FINSUM: This is a grave risk for the US because of how it would push up rates all through the economy, but we do not think the trade war has gotten this serious yet.
