Agency and Sovereign
Distinguish sovereign bonds, U.S. agency debt, GSE obligations, and government-backed securities by obligor, guarantee, currency, and law.
Compare Treasury, sovereign, agency, gilt, inflation-linked, and stripped government securities by issuer, cash flow, currency, and support.
Government, Treasury, and agency bonds are public-sector or government-linked debt securities. Their risk depends on the actual obligor, written guarantee, payment currency, governing law, maturity, inflation linkage, embedded options, and market liquidity.
The phrase “government-backed” is not enough to value a security. A direct sovereign obligation, a GSE bond, an agency-guaranteed mortgage security, an inflation-linked bond, and a stripped coupon can have very different cash flows even when all have a public-sector connection.
Use Treasury Bills, Notes, Bonds, and Securities for U.S. Treasury auctions, pricing, bills, coupon securities, and on-the-run status.
Use Agency, Sovereign, and Government-Backed Bonds when the obligor, guarantee, sovereign currency, or legal support is the central issue.
Use Gilts, Index-Linked, and Undated Government Bonds for UK conventional gilts, RPI-linked gilts, gilt strips, and historical undated structures.
Use Inflation-Linked Government Securities when principal or interest changes with a specified inflation measure.
Use Treasury STRIPS, Zero-Coupon Securities, and Receipts when one future principal or coupon payment is separated and traded independently.
