A financial institution can hedge its interest rate risk by:

• setting the duration of its assets, weighted by the market value of its assets to one half that of the duration of the liabilities, weighted by the market value of the liabilities.
• setting the duration of its assets equal to half that of the duration of its liabilities.
• matching the duration of its assets to the duration of its liabilities.
• matching the duration of its assets, weighted by the market value of its assets with the duration of its liabilities, weighted by the market value of its liabilities.
