December 7, 1994 Repurchase agreements (repos), reverse repos and securities lending markets permit a variety of institutions to conduct a broad range of financial transactions efficiently. In addition, they allow financial market participants to augment the returns on their cash holdings and securities portfolios. Canadian repo and securities lending markets have grown rapidly in recent years, following the expansion of such markets in major financial centres around the world; the volume of transactions in Canada now averages between $35 billion and $50 billion per day. The author notes that structural and regulatory changes in Canada have played important roles in promoting this growth. The vast majority of repo and securities lending transactions involve securities issued by the Government of Canada—principally Government of Canada bonds.
