(Bloomberg) -- Yields on Treasury bills for early June soared in New York trading Tuesday in the wake of a warning from Treasury Secretary Janet Yellen that the US government could run into debt-ceiling limitations as soon as the start of next month.
Even on late Monday, after the announcement by Yellen and a similar one from the non-partisan Congressional Budget Office, the highest rates on Treasury bills were evident around late July and August, signaling greatest concern around that point. But that has since shifted to early June amid the greater liquidity of US morning trading.
Yields on early June bills are now firmly above 5%, with some above 5.3%. May yields, by contrast are substantially lower, while those for much of July are also below 5%. There is another kink up around early August, reflecting heightened concerns around that period.
“The move in bills is a repositioning for the new X-date with the aid of morning market liquidity,” said TD Securities strategist Gennadiy Goldberg. “The news yesterday came out a bit too late for the market to properly reprice” he said, but “given the early-June warning by both Yellen and the CBO, markets have to take notice.”
The variations between rates on different maturities come about because investors demand a yield premium for any securities that are likely due to be repaid shortly after the US runs out of borrowing capacity. That’s because the government won’t be able to sell fresh securities and get cash to repay holders.
The result, in times of debt-cap stress, is the emergence of kinks in the yield curve. The addition of premiums can appear somewhat haphazard though, in large part because the risks around running out of debt-ceiling headroom are not linear. If the Treasury can make it through until certain key dates where it gets fresh cash injections, for example the mid-June corporate tax date, then it can buy itself some additional breathing room.
T-bill pricing has suggested for some time a level of increased concern stretching from June through much of the US summer, and those rates remain notably elevated compared to securities maturing in the very near term. But within that spectrum of summer-maturity securities, some dates are more concerning than others, and the focus points have sharpened somewhat.
Despite the selloff in bills, Wrightson ICAP (LON:NXGN) economist Lou Crandall still believes the Treasury won’t run out of fiscal resources until July, but acknowledged the department’s updated cash flow forecasts are possible and “its concerns about a debt-ceiling accident in June are not unfounded.”
“We suspect that the June X-date outlook will remain fluid at least until after the middle of this month,” Crandall wrote in a note to clients.
