Which of the following statements is true?

Deterioration in the balance sheets of key counterparties is a concern for a liquidity manager even though it may not immediately affect a firm, and this is true because counterparty failures may lead to liquidity shortfalls for an institution for no fault of its own. It is important for a liquidity risk manager to watch the health of key counterparties where exposure is concentrated and take timely steps to reduce it should the health deteriorate.

Under times of liquidity stress, prepayments of loans extended will decline while withdrawals of demand deposits are likely to increase. Both will not decrease, and therefore Choice 'b' is incorrect.

A bank is exposed to the undrawn portions of a line of credit extended to a borrower as the borrower, with superior information on its own finances, is likely to draw upon undrawn lines of credit thereby increasing the bank's exposure. Therefore Choice 'a' is incorrect. Generally, a portion of the undrawn part is counted towards a liquidity outflow.

Longevity risk is the risk facing sellers of annuities that their clients will outlive their assumptions on their length of life, while mortality risk is the downside risk for an insurer that clients will die sooner than expected causing the reserves to fall short of what is needed. Therefore Choice 'd' is not correct as the opposite is true.
