Treasury bill supply could rise by $1 trillion by the end of 2023, but the impending debt ceiling episode will complicate the timing, according to Bank of America strategists.
Strategists Mark Cabana and Katie Craig estimate Treasury will issue about $193 billion of bills in 4Q 2022 and $257 billion in 1Q 2023, with particularly strong months of supply in November, February and March because they are typically heavy deficit months that require additional issuance to sustain the cash balance
However, bill supply projections and the associated market impact are complicated by uncertainty around the timing of the debt limit, another round of money-market reform and the Federal Reserve’s quantitative tightening
Positive quarters of bill supply should help cheapen bills relative to overnight index swaps, and strategists estimate spreads should narrow by 10 basis points or more
Still, the monthly path of bill issuance is “much less clear” because of the debt ceiling, which could become constraining as early as December 2022
At that point Treasury would enter a debt issuance suspension period, which would restrict their ability to issue debt -- likely cutting bills to keep coupon sizes unchanged
Strategists project the potential default, or x-date, would be in August or September 2023. After that, there would be a surge of bill supply to replenish the cash balance
