US Long-Term Borrowing Costs Surge Over Deficit Concerns

In This Article:

(Bloomberg) -- Bond investors are demanding more and more compensation to hold long-dated US debt as global markets grow anxious about the widening fiscal deficit in the world’s biggest economy.

The US 10-year term premium — or the extra return investors demand to own longer-term debt instead of a series of shorter ones — has climbed to near 1%, a level last seen in 2014. It’s a measure of how jittery investors are about plans to raise the scale of future borrowing.

While bonds pared some of their weekly losses on Friday, investors were still clearly focused on the US’s funding challenges after Moody’s Ratings stripped the nation of its last top-tier credit score. This week, the US House of Representatives passed a multi-trillion dollar bill extending Trump’s tax cuts, and an auction of 20-year Treasuries attracted weak demand.

US Yields Slide as Trump Tariff Threat Reignites Growth Concerns

“The danger for now is that this fiscal phenomenon feeds on itself,” said Ella Hoxha, head of fixed income at Newton Investment Management, in an interview with Bloomberg TV. “That should be somewhat of a concern, certainly for risky assets and certainly for policymakers as well, as they have to finance at much higher interest rates.”

US long-term borrowing costs surged this week, with the 30-year yield climbing to 5.15% — just shy of its highest level in nearly 20 years. The real rate for the same tenor — which is adjusted for inflation — closed at the most elevated level since 2008 on Wednesday.

The moves eased on Friday as the selloff attracted buyers and President Donald Trump threatened a sweeping tariffs on the European Union and Apple Inc. The 30-year yield traded just above 5% as of 2:45 p.m. in London, up for a fourth week.

Bank of America Corp.’s Michael Hartnett said investors should take the opportunity to add long-dated Treasuries as the US government is likely to heed warnings from bond vigilantes to bring its debt under control.

Others were more circumspect, pointing to periods where term premium in 10-year notes was far higher than it is now. In the first decade of this century, it averaged a level of more than 150 basis points, according to the New York Fed’s gauge, before plunging in the years of ultra-easy monetary policy.
