From the Collaborative Bond and Money Market Data Portal
Collateral Eligibility refers to the criteria a central bank or counterparty uses to decide which assets it will accept as security when providing funding or liquidity. These rules govern asset type, credit quality, currency, issuer, and settlement, shaping what borrowers can pledge to access central bank reserves or private repo funding.
Data Model: In the CMDportal Collaborative Bond and Money Market Data Model, Eligibility appears as a BOOL (Yes/No) and is available as a filtering tool in Datasheet and Instrument search tools.
Impact on Money Markets
Eligibility is a primary lever on short-term funding and liquidity distribution. Broadening the eligible set expands the pool of assets firms can monetise, easing funding stress; tightening it does the reverse. Central Bank eligibility transmits into repo markets, where central-bank-eligible assets trade richer (lower repo rates, higher demand), influencing secured funding costs and the collateral premium available to cash investors. In a repo-led framework, eligibility defines the outer boundary of the liquidity backstop.
Impact on Bond Markets
Eligibility is a material driver of relative value: qualifying securities carry an embedded funding and liquidity option, commanding tighter spreads and better liquidity, while losing eligibility widens spreads. Any change by the central bank impacts the financing value of eligible credit and support issuance in those sectors. Pledgeability strengthens the buyer base.

Eligibility sits at the core of monetary policy transmission and financial stability, determining how effectively a central bank can supply reserves, anchor short-term rates, and prevent funding dislocations, while haircut calibration protects its balance sheet. It is also a growing channel for net zero objectives: the BoE excludes thermal-coal issuers and applies transition-risk haircut add-ons, steering relative funding costs toward transition-aligned issuers. Across the cycle, generous eligibility cushions stress and recession, while higher haircuts or narrower eligibility can amplify funding pressure under tightening.
