In 2002, mortgage-related securities in the US had $4,705 billion outstanding, equivalent to 45.0% of US GDP that year.
Notes on verification
SIFMA and BEA data corroborate the approximate dollar figure and GDP ratio, though the exact 45.0% figure could not be independently reproduced to the decimal; minor discrepancies may stem from differing GDP baselines.
