eBay's Stock Plunges as De Minimis Tariff Policy Shift Sends Trading Volume to 131st in Market Activity

On August 29, 2025, eBay (EBAY) closed with a 2.36% decline, trading at a volume of $660 million, ranking 131st in market activity. The selloff follows the U.S. termination of the de minimis tariff exemption, a policy shift that has disrupted cross-border e-commerce. eBay’s platform, which facilitates international transactions, now faces heightened scrutiny as buyers encounter import duties of up to 50% on purchases exceeding $800. This has led to operational challenges, including potential interruptions in user activity and revenue streams.

The policy change has disproportionately impacted companies reliant on low-cost international shipping. eBay’s shares have underperformed the Nasdaq over the past week, reflecting investor concerns about rising compliance costs and shifting consumer behavior. U.S. buyers, now burdened with unexpected import charges, may reduce spending on international marketplace listings, a core segment for eBay. Additionally, international sellers on the platform are reevaluating U.S. sales strategies due to increased logistical complexities and financial risks.

The broader e-commerce sector has seen mixed effects, with Amazon and Walmart experiencing less direct exposure. However, eBay’s business model, which thrives on third-party global sellers, remains vulnerable to regulatory shifts and supply chain disruptions. Analysts note that the company’s ability to adapt to these changes—through pricing adjustments, logistics reconfiguration, or expanded domestic offerings—will be critical in mitigating long-term revenue pressures.

Backtest results indicate that eBay’s stock has historically shown sensitivity to cross-border trade policy changes, with similar regulatory shocks historically leading to 5–10% volatility over short-term horizons. The current decline aligns with this pattern, underscoring the market’s reaction to the de minimis policy reversal and its implications for global e-commerce dynamics.
