To determine the haircut, i.e., to value the fund positions that financial institutions have received as collateral from borrowers, they can use the mandate-based approach. However, this approach is only a conservative estimation based on the stated investment profile of the fund. As such, it does not allow for the most efficient use of capital. Financial institutions are giving away potential that they could use elsewhere.
The most capital-efficient method for assessing funds under the standardized approach, suggested in the Basel framework, is by implementing the Look-through Approach (LTA). By adopting the LTA, financial institutions that accept funds as collateral can improve the risk weighting of the banking book and thus have a positive influence on capital requirements.
As an effect of this, more capital is freed up to carry out yield transactions. The more often and systematically a financial institution uses the LTA in connection with funds, the more capital is available for further loans or investments.
However, the LTA entails identifying each component of a fund as a direct investment i.e., as if each underlying component were held as an individual position by the financial institution.
