Final answer:
A 52-week Treasury bill is offered every week.
Step-by-step explanation:
A 52-week Treasury bill, often referred to as a one-year Treasury bill, is typically offered once a week. These bills are part of the U.S. Treasury's auction schedule, where they issue short-term securities to finance government operations. The 52-week T-bill is one of the longer-term offerings among Treasury securities.
The U.S. Treasury conducts regular auctions for various durations of Treasury bills, ranging from 4-week (1-month) to 52-week (1-year) periods, along with other longer-term securities. Among these, the 52-week Treasury bill stands out as a key option for investors seeking a relatively longer maturity period compared to shorter-term bills.
Investors often favor Treasury bills due to their low risk and stability, making them an attractive choice for short-term investment strategies. The weekly auctioning of the 52-week Treasury bill provides investors with regular opportunities to purchase these relatively longer-term securities, contributing to the liquidity and stability of the market.
