Four-week T-bill auction results
The U.S. Treasury auctioned $25 billion in one-month T-bill issuance on June 17. The issuance amount for one-month bills have been decreasing over the past four weeks. Issuance, which stood at $45 billion at the May 28 auction, has now come down to $25 billion.
The demand (as reflected in the bid-to-cover ratio) for these bills fell in this week, as investors began to shun fixed-rate bonds on inflation expectations. The bid-to-cover ratio for four-week T-bills slid from a high of 4.71x in the June 10 auction, to 4.47x in the June 17 auction.
The bid-to-cover ratio compares the number of bids received in a Treasury auction with the number of bids accepted (or the amount of securities issued). The higher the ratio, the greater the demand for the auctioned securities. A bid-to-cover ratio over two corresponds to a successful auction, while a ratio of less than one shows an under-bought auction.
Drop in demand for one-month bills
The drop in demand for four-week T-bills on inflationary concerns caused a rise in yields. Also, with the Consumer Price Index (or CPI) release coming stronger than expected and building inflation expectations, more investors are moving out of fixed-rate Treasuries, which became less attractive given the expected rise in inflation.
Primary dealers took center stage at the past week’s four-week T-bill auction, grabbing 85.06% of the total issue. Indirect bidders, including foreign banks and international authorities, grabbed 10.19% of the total issue—down from 30.35% the week before. Since indirect bidders generally purchase T-bills to be held to maturity, their lower share corresponds to lower end-user demand. The rest 4.75% of the issuance came in the hands of direct bidders.
Exchange-traded funds (or ETFs) investing in one-month T-bills are the SPDR Barclays Capital 1–3 Month T-Bill ETF (BIL) and the iShares Barclays Short Treasury Bond Fund (SHV). Investors can also invest in ETFs like the PIMCO Enhanced Short Maturity Exchange-Traded Fund (MINT), which also includes short-term corporate securities that offer higher returns for marginally higher risk. MINT invests in short-term securities such as T-bills, commercial papers, and mortgage-backed securities. A total of 70% of the fund’s assets are deployed in securities with maturity of less than a year. Goldman Sachs (GS) and Verizon Communication (VZ) form 2.7% of the total holdings of MINT.
