Most people have never heard of a Treasury auction.
As a mortgage broker, I watch them like a hawk — because they are one of the most direct indicators of where your mortgage rate is heading.
Here's the simple version:
The U.S. government borrows money by selling Treasury notes to investors worldwide. The 5-year and 10-year notes matter most for mortgage rates. When demand is strong, yields stay low. When demand weakens, yields rise — and your mortgage rate rises with them.
The number I watch is called the "indirect bid" — that's the proxy for foreign investor participation. Japan, China, the Gulf states. When they show up, rates stay manageable. When they don't, domestic buyers fill the gap — but only at higher yields.
We have major 5-year and 10-year auctions coming in the next few weeks.
Given everything happening geopolitically and with trade policy right now, foreign appetite for U.S. debt is genuinely uncertain in a way it hasn't been in years.
Those auction results will tell us more about where mortgage rates are going than anything you'll hear on financial television.
I'll be watching. More on Monday on why foreign demand may be structurally shifting — and what's driving it.
