Widening spreads on a bank's issued debt and credit default swaps (CDS) reflect increasing market concerns about the bank's creditworthiness and liquidity position, serving as a strong early warning indicator (EWI) of liquidity risk.

• Option A is incorrect: A decrease in peers' stock prices but not the bank's itself suggests the market still views the bank as resilient despite sector-wide pressures.
• Option B is incorrect: An increase in available credit lines indicates greater access to funding and improved liquidity, which is a positive sign, not a warning indicator.
• Option D is incorrect: Asset growth funded by an increase in stable liabilities is generally a safe funding strategy compared to using unstable wholesale funding.
