Central banks hold large portfolios of top-tier sovereign bonds that are highly sought after by commercial institutions to cover their short positions or satisfy regulatory liquidity metrics. To generate incremental income on these passive holdings, central banks run Securities Lending Programs.

[Bond Returned with Fee Payment] <--- [Central Bank Reinvests Cash in Short Repo] <---------------+
The central bank lends its high-quality bonds to pre-screened borrowers, requiring them to deposit liquid cash or alternative securities as collateral at a value exceeding the loan amount. The central bank reinvests the cash collateral in short-term repo markets, earning a secure return while retaining the right to recall its bonds if policy needs arise.
