Final answer:
An asset-liability time mismatch refers to a situation in macroeconomics where a bank's liabilities can be withdrawn in the short-term while its assets are being repaid in the long-term.
Step-by-step explanation:
An asset-liability time mismatch in macroeconomics refers to a situation where a bank's liabilities, such as deposits, can be withdrawn in the short-term while its assets, like loans, are being repaid in the long-term.
This can pose a problem for banks if interest rates rise because they may have to pay higher interest rates to depositors while receiving lower interest rates on their long-term loans.
To mitigate this risk, banks can choose to diversify their loans or hold a greater proportion of their assets in bonds and reserves.
