Trump’s 150-Day Tariff Clock: What Cross-Border Merchants Need to Know
Ricky
On February 20, the Supreme Court told the President his tariffs were illegal. By that evening, he had signed new ones. The 15% global tariff under the Trade Act of 1974 has a built-in expiration: 150 days. For merchants, this creates a window of uncertainty and a reason to rethink how you settle cross-border transactions.
What just happened: from IEEPA to Section 122
In Learning Resources, Inc. v. Trump, the Supreme Court ruled 6-3 that the International Emergency Economic Powers Act does not authorize the president to impose tariffs. The Court concluded that IEEPA’s grant of authority to “regulate importation” does not include the power to levy duties, a power the Constitution reserves for Congress under Article I. The decision invalidated the Reciprocal Tariffs and Trafficking and Immigration Tariffs that had been in place since 2025.
Within hours, the White House pivoted to Section 122 of the Trade Act of 1974. This provision allows the president to impose temporary import surcharges to address “fundamental international payments problems,” specifically large balance-of-payments deficits. The initial rate was set at 10%. Within 48 hours, it was raised to 15%, the statutory maximum.
The legal basis is contested. Trade experts at Fortune note that the U.S. does not technically have a balance-of-payments deficit. It has a trade deficit offset by a capital account surplus. Whether courts will intervene again is an open question. But for now, the tariffs are in effect.
The 150-day clock: dates merchants should track
Section 122 contains a constraint that IEEPA did not: a 150-day limit. The tariff order took effect on February 24, 2026. That means the clock runs out around July 24, 2026. After that date, the tariffs expire unless Congress votes to extend them.
Congressional extension looks unlikely. Both the House and Senate previously passed bills disapproving of the IEEPA tariffs. Republican lawmakers face a difficult vote on an unpopular issue heading into election season. The political math does not favor extension.
Here is the timeline that matters for your business:
- February 20: SCOTUS strikes down IEEPA tariffs
- February 22: Section 122 tariff signed at 10%
- February 24: Rate raised to 15%, tariff takes effect
- July 18: GENIUS Act implementation deadline — federal regulators must finalize stablecoin rules
- July 24: 150-day tariff expiration date
This timing is not accidental. By late July, the U.S. will simultaneously resolve, or fail to resolve, its trade policy and its stablecoin regulatory framework. If you settle cross-border payments, both outcomes affect you directly.
How 15% tariffs hit cross-border e-commerce
The 15% surcharge applies to nearly all imports, with limited exceptions for certain natural resources, agricultural products, and passenger vehicles. For cross-border e-commerce merchants, the impact is immediate.
Pricing uncertainty. You cannot set stable prices when your cost of goods changes based on a 150-day political clock. Merchants importing from China, Southeast Asia, and the EU face different effective rates depending on existing trade agreements and product categories. Planning inventory purchases six months out becomes guesswork.
Supplier cost pass-through. Your overseas suppliers are raising prices to compensate for reduced demand and currency fluctuations. Even if you source domestically, your competitors’ pricing shifts affect your market position. The full geopolitical chain reaction, from the Strait of Hormuz disruptions to tariff-driven supply rerouting, adds cost at every step.
FX volatility from headlines. Every tariff announcement triggers currency swings. The dollar strengthened on the SCOTUS ruling, then weakened on Section 122 uncertainty. For merchants converting between currencies at settlement, these swings can erase your margin. Combined with fear-driven capital flows, the FX environment is the most unpredictable it has been in years.
Small and medium merchants are most exposed. Unlike large enterprises with hedging desks and diversified supply chains, SMEs absorb these costs directly. According to PayPal and the National Cryptocurrency Association, 39% of U.S. merchants now accept crypto at checkout, a number that has grown sharply as traditional payment rails become more expensive and less predictable.
Why your settlement currency matters more than your tariff rate
Tariffs change your cost of goods by up to 15%. That is significant. But if you also lose 5-10% to BTC volatility during the settlement window, you have made the problem worse. We saw this play out during the February price action: $350 million in crypto positions were liquidated in 48 hours as markets reacted to the SCOTUS ruling and subsequent tariff announcements.
Stablecoin settlement fixes this. When you invoice in USDT or USDC and your counterparty pays in stablecoins, the dollar value is locked at the moment of transaction. No conversion window. No exchange rate slippage. No waiting three to five business days for a wire to clear while the market moves against you.
Non-custodial settlement goes further. During periods of policy uncertainty, counterparty risk increases. Banks freeze accounts. Payment processors hold funds for “compliance review.” A non-custodial gateway means no intermediary holds your money. The payment goes directly from buyer to your wallet. In an environment where tariff policy changes overnight, eliminating intermediary risk is not a philosophical preference. It is a practical requirement.
What to do before the 150 days run out
You have until late July before tariff policy shifts again. Use the window strategically.
1. Diversify payment acceptance. Add stablecoin options alongside your existing payment rails. You do not need to replace credit cards or bank transfers. You need alternatives for when those channels become slow, expensive, or unreliable. The 2026 macro reset is pushing merchants toward multi-rail payment stacks. Merchants who set up infrastructure now will be ready when demand accelerates.
2. Price in local currency, settle in stablecoins. Your customers want to see prices in their currency. Your accounting needs predictable dollar values. Stablecoin settlement bridges both. Quote in EUR, GBP, or SGD. Accept payment in USDT or USDC. Your customer sees familiar pricing; you receive a dollar-pegged asset with no conversion delay.
3. Use non-custodial gateways to cut counterparty risk. When regulations change every 150 days and geopolitical events disrupt supply chains weekly, you cannot afford to have your settlement funds sitting in someone else’s account. Non-custodial means you control the keys. Funds arrive in your wallet, not a pooled account subject to freezes or delays.
Your next invoice should not depend on a shipping lane
When oil prices spike 13% overnight and currencies swing on headlines, merchants using traditional payment rails absorb the damage. Aurpay settles in stablecoins — same value sent, same value received, regardless of what happens in the Strait of Hormuz. Start accepting stablecoins.
