- The Supreme Court ruled that tariffs imposed under the 1977 International Emergency Economic Powers Act (IEEPA) were illegal. By the first 20 days of May, the U.S. Customs and Border Protection (CBP) had already issued approximately $17 billion in refunds, far exceeding the $3 billion for the entire month of April.
- The potential total refund amount, combined with statutory interest, is expected to reach up to $166 billion, making CBP one of the largest federal spending agencies for the month, with the risk of a net deficit in the tariff account for May.
- The historical tariff shift has triggered widespread litigation in the retail and logistics sectors, with giants like Amazon (AMZN:US) and FedEx (FDX:US) facing the risk of class-action lawsuits over the ownership of hundreds of millions of dollars in refunds.
Historic Refund Surge Impacts Monthly Fiscal Balance
According to the latest court documents disclosed by the U.S. Customs and Border Protection, approximately $17 billion in tariff refunds were processed and executed in the first 20 days of May. If the current pace of online clearance continues into late May, the total tariff refunds for the month will directly exceed the $22.12 billion in total tariff revenue for April. This fiscal anomaly stems from the Supreme Court's ruling against the legality of historical tariffs, forcing the White House to officially launch the CAPE online refund system on April 20. President Donald Trump, although publicly expressing strong dissatisfaction with the ruling, also acknowledged the government's obligation to return approximately $149 billion in principal. The latest court testimony from customs officials indicates that if accumulated interest is included, the total eligible refund amount will rise to $166 billion, making the monthly expenditure through customs channels nearly rival the Medicare prescription drug plan.
Corporate Cash Flow Improvement Accompanied by Secondary Compliance Litigation Risk
As the CAPE approval system becomes more streamlined, the micro cash flow of the import supply chain is being released in stages. Toy manufacturer Basic Fun expects to receive the full amount within 90 days, while large retailers like Walmart have begun incorporating this unexpected funding into their budget planning, declaring that it will be prioritized for end-product price reductions. However, the internal struggle over refund windfalls is triggering a chain of legal disputes. Since the historical tariff costs have often been passed on to end consumers in actual transactions, there are already at least 17 lawsuits against logistics and retail giants such as FedEx, Costco, and UPS. E-commerce leader Amazon also faces class-action lawsuits, accused of illegally retaining hundreds of millions of dollars in tax refunds that should belong to customers. If the court rules that companies must transfer refunds to historical consumers, the relevant sectors will face high accounting write-offs and legal compliance costs.
Debt Ratio Breaks Century-Old Red Line, Suppressing Long-Term U.S. Treasury Credit
From a broader fiscal macro balance perspective, this massive refund is exerting additional pressure on the already heavily indebted U.S. finances. Treasury data shows that the cumulative deficit for the fiscal year 2026 has reached $954 billion, with the total federal debt held by the public surpassing $31.27 trillion. This has pushed the debt-to-GDP ratio in non-war times to 100.2%, setting a historical extreme since the end of World War II. Shenwan Hongyuan Securities pointed out in its research report that this tariff refund will directly raise the U.S. deficit rate for the current fiscal year by 0.5 to 0.6 percentage points. If future geopolitical conflicts, such as the U.S.-Iran situation, lead to an unexpected expansion of national defense allocations, the existing fiscal budget balance will be difficult to maintain. The widening fiscal gap may force the Treasury to increase the issuance of government bonds in the third quarter, thereby exerting upward pressure on long-term U.S. Treasury yields.
