Retail sales climbed in the first quarter, fueled by two temporary forces now fading from the economy. Tax refunds and buy-now-pay-later (BNPL) services lifted consumer spending above what underlying purchasing power would suggest.

The strength masks a softer consumer underneath. Average tax refunds have already begun shrinking compared to last year. BNPL adoption, which peaked during pandemic spending, is cooling as consumers face higher interest rates and tighter budgets. Credit card balances remain elevated, and savings rates have declined from pandemic highs.

Retailers benefited from the timing. Companies like Target, Walmart, and Macy's reported solid comparable-store sales in early 2024, driven partly by shoppers using refund money immediately. BNPL services like Affirm and Klarna enabled purchases that wouldn't happen with cash alone.

The real test arrives now. As tax season ends and BNPL usage normalizes, retailers face a crucial question. Can consumer spending hold without these tailwinds? Payment delinquencies are rising in some sectors. Credit utilization sits near record levels, suggesting households have maxed out borrowing capacity.

Shoppers who delayed purchases using BNPL still face payment obligations ahead, eating into future spending power. This creates a timing problem for retailers heading into spring and summer selling seasons, traditionally weaker periods than the holiday rush.

Analysts point to diverging consumer behavior. Higher-income households continue spending freely. Lower and middle-income earners cut back sharply, relying more heavily on credit and one-time refunds to maintain consumption levels.

For savers and investors, this signals caution. Retail earnings growth may decelerate through spring. Credit card issuers and lenders face higher default risks. BNPL company stocks could face headwinds as usage moderates and credit stress
