As private credit funds like Vanguard Credit experience rapid growth in assets under management (AUM), they may face pressure to deploy capital quickly to meet investor expectations. This can lead:

• Increased competition for deals, particularly in a niche market like technology startups.
• A potential relaxation of underwriting standards to secure investments, resulting in higher exposure to credit risk as loans are made to riskier borrowers or with less stringent terms.

A is incorrect: While stale valuations are a feature of private credit markets, this risk is not directly exacerbated by growth in AUM or competition.
C is incorrect: Floating rate loans are less exposed to interest rate risk for lenders, as they adjust with market rates, and are not specifically tied to rapid growth in AUM.
D is incorrect: Closed-end fund structures are designed to match the illiquidity of private credit assets with investor expectations, mitigating liquidity risk.
