A Brief Retail Investor Guide to U.S. Treasuries
All U.S. Treasuries listed below are available in US$100 increments. (U.S. Savings Bonds are available in smaller increments.) My understanding is that all of these U.S. Treasuries and U.S. Savings Bonds are completely U.S. tax free when they're held as individual issues (not within a U.S. fund "wrapper") by a non-U.S. person who is not engaged in a U.S. trade or U.S. business. That is, ordinary residents of Singapore who are not U.S. persons should be able to buy and hold individual U.S. Treasuries without any U.S. tax consequences.
Each U.S. Treasury that's issued has a unique identifier known as a CUSIP. Use the CUSIP if you're looking for a particular bill, note, bond, or TIPS at your broker. The U.S. Treasury announces auctions
on its Web site if you'd like to monitor auction dates to try to buy a particular issue at original auction. At the same site you can find another link to the U.S. Treasury's tentative schedule of auctions. The tentative schedule will not have CUSIPs listed.
U.S. Treasuries and U.S. Savings Bonds are the world's #1 safest parking vehicles for U.S. dollars. They are general debt obligations of the U.S. federal government, backed by its full faith and credit. All these obligations are in nominal U.S. dollar terms except for TIPS and Series I Savings Bonds which are real return (a.k.a. inflation-indexed) bonds. TIPS and Series I Savings Bonds assure particular financial outcomes that are grounded in the real domestic U.S. consumer purchasing power of the U.S. dollar.
U.S. Treasury Bills
Available in 4, 8, 13, 26, and 52 week tenors. They're very simple: pay $X, get face value at maturity. (For example: pay $99, get $100 later.) No coupons.
U.S. Treasury Notes
Available in 2, 3, 5, 7, and 10 year tenors. Interest paid every 6 months.
U.S. Treasury Bonds
Available in 20 and 30 year tenors. Interest paid every 6 months. (Yes, the Treasury Bonds and Treasury Notes are the same except for the different tenors available.)
U.S. Treasury Inflation Protected Securities (TIPS)
Available in 5, 10, and 30 year tenors. The principal is periodically adjusted up or down based on the U.S. Consumer Price Index's movements. If the CPI is lower at maturity compared to the issue date then you're guaranteed face value (defense against deflation). Pays fixed interest every 6 months, and the interest is computed based on the inflation-adjusted principal.
U.S. Floating Rate Notes (FRNs)
Available in a 2 year tenor only. Pays variable interest quarterly based on the 13 week T-bill rate.
U.S. Savings Bonds
Available in Series EE (traditional) and Series I (inflation-adjusted) variants. U.S. Savings Bonds are at least difficult for international (non-U.S.) investors to buy, and you cannot buy much of them per year. For example, Series I purchases are limited to US$10,000 per year per person. You usually need a TreasuryDirect account to buy them. Most residents of Singapore can ignore U.S. Savings Bonds.
