Bond Market vs Stock Market Size: Which Is Bigger?
Short answer. The global bond market is generally larger than the global stock market. Outstanding bonds worldwide are commonly estimated at well over $100 trillion, against roughly $100-120 trillion of listed equity market value, and the gap depends on the year and the data source. Bonds are bigger because governments, banks and companies borrow continuously.

Frequently asked questions
Which is bigger in the US?
Totals are of similar size and flip with prices. US bond market debt outstanding is typically cited around $50-60 trillion, and US equity market cap tends to be in the same range or higher after rallies.
Why is the bond number so rough?
Sources (BIS, SIFMA, central banks) count different instruments, and many bonds are private or not publicly priced. Stock market cap is more precise because shares trade on public exchanges.
Does bigger mean riskier?
No. Size describes how much money is in each market, not volatility. Bond prices tend to move less than stock prices.
