Answer: Widening spreads on the bank's issued debt and credit default swap

The correct answer is C, which indicates that widening spreads on the bank's issued debt and credit default swap should be considered as the strongest warning signal for potential liquidity risk at the bank. This is because wider spreads suggest a loss of market confidence in the bank, leading to a higher cost of funding. This could potentially make it more difficult for the bank to access the necessary funds to meet its short-term obligations, thereby increasing its liquidity risk. Option A is incorrect because a decrease in the stock price of the bank's peers but not in the bank's own stock price does not necessarily signal heightened liquidity risk. It could be due to various factors unrelated to liquidity. Option B is also incorrect as an increase in credit lines received from other financial institutions is generally a positive sign for liquidity, not a warning signal. A decrease in credit lines would be more problematic as it could limit the bank's access to funds. Option D is incorrect because significant asset growth funded by an increase in stable liabilities is typically a positive sign for a bank's liquidity position. Rapid asset growth funded by volatile liabilities would be more concerning as it could increase the bank's vulnerability to liquidity risk if those liabilities were to become unstable or withdrawn.
