Rates Spark: The Yield Race to the Top Continues

US yields are rising across the curve but T-bills are at the intersection of a better economic outlook and a debt ceiling. Sterling rates are now offering a pick-up to dollar equivalents. This makes sense at the front end but less so at longer maturitiesh2 US T-bills at the intersection of the debt ceiling-recovery Venn diagram/h2

US T-bills find themselves at the intersection of two uncomfortable developments. First, the longer time passes without any dramatic fall in economic data, the more the fear of a credit crunch fades in investors’ minds. Bank results so far this reporting season have failed to produce a recovery in the KBW US regional banks stock index, but the broader bank stock gauge has shown clearer signs of a rebound. This is probably too early to sound the all-clear but it is also fair to say that bank fears are no longer an impediment to higher front-end rates, and 2Y yields are still around 90bp below their each March peak.

Markets face upwards of $400bn in T-bill issuance, and a commensurate drain of liquidity

The second development is the approaching debt ceiling showdown. There is a clear hump in the T-bill curve around the July-August maturity dates when default risk is deemed most elevated. Information on tax receipts this week may help refine that estimate and so drive relative moves between securities. The fact is that ‘X-date’ is still roughly three months away, so providing a precise estimate at this stage is challenging. The other driver is, of course, political developments, but widespread expectation is for any solution to be found much closer to the deadline this summer.

Once a compromise is found, and it is our expectation that one will be found, T-bills face another challenge: the Treasury ramping up issuance to re-build a cash buffer in the Treasury General Account (TGA). As of last week, its balance was $109bn, but it is likely to go up this week thanks to tax receipts, before going down into the X-date. Assuming the Treasury aims to build its balance back to $500-600bn after the debt ceiling is solved, markets face upwards of $400bn in T-bill issuance, and a commensurate drain of liquidity.

The default probability 'hump' in US T-bill yields is moving forward to June
