Costco Defies Economic Gloom with Strong March Sales

​While markets yo-yo and economic anxiety thickens, Costco is quietly doing what it does best: stacking up sales.

The warehouse giant reported $25.51 billion in March revenue, up a robust 8.6% year-over-year, even as consumers face rising living costs and a foggy economic future. Same-store sales jumped 6.4%, while e-commerce posted a surprising 16.2% gain—proof that even in shaky times, shoppers are still clicking and carting.

And the stock? It’s loving the resilience. Costco shares were up 6.2% during the day and inched higher after hours, riding a broader market rebound triggered by President Trump’s unexpected 90-day tariff pause.

Yes, those same tariffs that spooked the markets last week. Trump’s surprise move included lowering the general tariff rate to 10% and offering a reprieve to many nations—though China wasn’t so lucky, now facing a steep 125% rate. The tariff cooldown helped ease investor jitters, and Costco was one of the first retailers to reflect that boost.

Still, the retailer isn’t blind to the challenges ahead. Just last month, Costco cautioned that shoppers could remain “choiceful”—a polite way of saying selective and price-sensitive—as inflation lingers and more economic bumps appear on the road.

Yet even with global tensions and tighter wallets, Costco is holding its ground. Bulk value, membership perks, and the company’s famously tight margins seem to be keeping customer loyalty intact.

​Bottom line: In a time of uncertainty, Costco is proving that warehouse bargains still win. And as long as the aisles stay full and the hot dog combo stays $1.50, they might keep defying the gloom.
