Anatomy of a US Treasury Sell-Off

The bond market has been extremely volatile the past couple of weeks since the introduction of global tariffs by the US. Bond yields have sold off almost 50 basis points, and today we'd like to examine why did that occur, what's next, and how should investors think about duration in this environment?

We think there are four key factors that have contributed to the US Treasury sell-off in April. The first reason is volatility in the equity markets. The volatility in the equity markets has led to deleveraging and has led to margin calls, which has caused forced sales of US Treasuries.

These Treasuries wind up on dealer balance sheets. We see repo rates inch higher as a way to reflect that lack of buyers in the market. We do not think the unwind of the basis trade contributed to the sell-off, but it certainly was a factor once momentum had begun.

Reason number two is tariffs. We don't know quite the magnitude or the extent of the tariffs, but we do know that tariffs will contribute to inflation in 2025. And this is making investors nervous. We also know the Federal Reserve has commented that they are worried about tariffs and the inflationary impact. And that they might be hesitant to reduce interest rates.

Factor number three are the fiscal concerns. They're intensifying as the budget-reconciliation blueprint progresses through Congress. Rumored additional deficit worries are spooking the bond market and investors and are causing additional pressure on the term premium, especially out to 30 years.

Factor four, foreign investor divestment. Secretary Bessent recently confirmed that there was no evidence of foreign selling of US Treasuries in April. We're going to put this more in the rumor right now more so than the fact category, but it is something to keep an eye on as we roll through this global tariff war.
