Tariffs go up, refunds go out

Washington ran two stories side by side on 10 March. The administration announced plans to raise Section 122 tariffs to the legal maximum of 15 per cent. The same day, the US Court of International Trade ordered US Customs to start paying out billions of dollars in refunds on the voided IEEPA duties.

Collecting with one hand, paying with the other

Rolling out higher tariffs while courts order refunds shows how muddled trade policy has become. The White House wants new duties to keep its leverage in negotiations. The courts, meanwhile, are drawing down the Treasury to repay companies hurt by the tariffs they ruled unlawful. Corporate treasurers are paying new 15 per cent surcharges with one hand and banking refund cheques with the other.

The two flows do not cancel out, for several reasons. They reach different companies, because a firm that imported heavily in 2025 and has since cut back will receive more than it pays, while one that has grown its imports will pay more than it gets. They arrive at different times, since the new surcharge is collected as goods clear the border while refunds depend on how quickly Customs processes claims. And they carry different legal lives: the refund is money owed, while the surcharge under Section 122 expires after 150 days unless Congress extends it.

Why go to the ceiling

Raising the surcharge to the cap uses up the last room the statute allows. Section 122 permits temporary duties of up to 15 per cent to deal with balance-of-payments problems, so the administration now has no further rate to threaten under this law, and its remaining leverage lies in other statutes that require investigations. The move signals that the White House values revenue and bargaining pressure in the next few months more than it values keeping something in reserve. It also brings the flat surcharge closer to the level of some of the voided emergency duties, which reduces the gain importers expected from the court's ruling.

Strain on the bond market

Bond traders face an operational headache. The Treasury will have to sell hundreds of billions of dollars of new debt to pay the refunds, while new duties disrupt trade and push up headline inflation.

The financing will fall mostly on bills. Treasury debt managers have told the market they plan to keep the size of their longer-dated auctions steady for several quarters, and bills are the only instrument they can scale up quickly without breaking that guidance. The cash will have to come from money-market funds and other short-term investors, and with the Fed's reverse repo facility largely drained there is little idle money waiting to absorb new supply. The Federal Reserve's own purchases of bills, begun in December to keep bank reserves ample, will soak up some of it but were not designed for a surge of this size.

The inflation side compounds the problem for longer-dated bonds. A higher surcharge raises the price of imported goods again at a time when inflation is already above target, and investors in Treasuries will demand compensation for both. Breakeven inflation rates, the gap between nominal yields and those on inflation-protected bonds, are the place to see that demand.

The timing of the refunds creates a further puzzle for cash management. The Treasury's cash balance at the Fed swings sharply around tax dates, and April is usually the month when receipts peak. Refunds paid in March, before those receipts arrive, would draw the balance down faster than debt managers had planned, while payments timed for after the April tax date would be easier to absorb. The Court of International Trade has ordered payments to begin, but not a timetable for how quickly they must be completed, and that gap gives the Treasury some room to manage the flow.

The 150-day clock matters here too. Every month the higher surcharge runs brings in more revenue, but it also moves closer to the date when it must lapse, and a Congress unwilling to extend it would leave the Treasury with refunds still going out and no replacement tariff coming in.

Winners and losers

Large importers with heavy 2025 purchases and good records are the clearest winners, since they collect refunds on past duties and can use the cash to cushion the new surcharge. Domestic producers competing with imports gain from the higher rate. The losers are smaller importers that must fund the 15 per cent surcharge from working capital while waiting months for refunds, retailers that absorbed part of last year's duties and now face higher costs again, and consumers, who see prices rise without any share of the refunds. Holders of short-dated Treasuries may face slightly higher yields as bill supply climbs.

More coherent than it looks

The strongest defence of the policy is that it is less contradictory than it looks. From the administration's side, the refunds are a legal obligation it cannot avoid, while the surcharge is a policy choice it is entitled to make, and there is no reason one should wait for the other. The net cash effect could also prove smaller than the headlines suggest if refunds trickle out slowly while the higher surcharge brings in steady receipts. That argument has merit for the budget over a full year, but it does little for the importers and bond dealers who must handle both flows at once.

Past episodes suggest the refund side will move slowly. After the Supreme Court struck down the harbour maintenance tax on exports in 1998, repayments took years. Customs today has automated systems that can reverse duties on entries not yet finalised, but finalised entries require protests, and the agency's staff is limited.

The signals to watch are the Treasury's quarterly refunding announcement in early May, weekly bill auction sizes, customs deposits and refunds in the daily Treasury statement, guidance from Customs on processing claims, and any move in Congress to extend the surcharge beyond its 150-day limit. Paying out refunds while raising Section 122 surcharges makes little sense. It will probably mean heavier Treasury borrowing this spring and more paperwork and delay for importers.
