A 10-year yield is easy to compare across countries, but the markets behind those yields are not interchangeable. Some sovereigns issue across a deep benchmark curve, others rely on fewer lines. Some markets have large inflation-linked segments, active futures and broad foreign participation; others are dominated by domestic institutions or bank balance sheets.
The BondStats Global Bond Market Structure Database is built to describe those differences systematically. It focuses on how markets are organized: who issues, how debt is sold, which maturities act as benchmarks, how securities settle, which investor groups matter and where liquidity is concentrated.
This is not another global-yields page and not a duplicate of country profiles. The purpose is structural comparison — the institutional architecture that determines how a bond market behaves when supply, policy or risk conditions change.
Market size is only the first layer
The nominal size of a bond market says little about its internal composition. A market can be large because of central-government borrowing, financial-sector issuance, covered bonds or corporate debt. For investors, those distinctions matter because they affect liquidity, duration supply, collateral availability and sensitivity to the domestic banking system.
A structural database therefore separates market segments instead of collapsing them into one total. The goal is to understand the architecture of tradable fixed income rather than to produce a league table with false precision.
Benchmark curves, issuance conventions and liquidity
Benchmark design strongly influences how investors hedge and price risk. Regularly reopened government lines can concentrate liquidity, while fragmented issuance may spread activity across many securities. Futures, repo markets and primary-dealer systems can further reinforce the importance of particular maturities.
These features help explain why identical macro shocks can produce different trading behavior in two sovereign markets. Market structure determines where liquidity lives and how quickly price discovery can move through the curve.
The investor base is part of the structure
Domestic banks, insurers, pension funds, households, foreign reserve managers and global asset managers do not respond to the same incentives. Their relative importance can shape auction demand, hedging behavior and the response to currency moves. BondStats treats investor composition as a structural characteristic rather than a separate anecdote.
The resulting framework creates a bridge between sovereign debt, capital flows and market plumbing: issuance creates the securities, investors absorb them, and settlement and collateral systems allow them to circulate through the financial system.
