Saturday Night Escalation -- Rate Jumps to 15% Maximum, Markets Haven't Priced It Yet

What Happened
Less than 24 hours after signing an executive order for a 10% global tariff under Section 122, Trump raised the rate to 15% on Saturday -- the maximum allowed under the Trade Act of 1974. This is the first time any president has invoked Section 122 in its 52-year history.

What Changed From Friday to Saturday

• Friday evening: 10% global tariff signed under Section 122 after Supreme Court struck down IEEPA tariffs
• Saturday morning: Rate increased to 15%, the statutory ceiling
• Effective: Tuesday, February 24 at 12:01 AM EST
• Duration: 150 days (expires mid-July) unless Congress extends

The Yale Budget Lab calculates the effective tariff rate is now 14.5% -- slightly above where it sat before the Supreme Court ruling on Friday. So despite the legal loss, the administration managed to get tariff rates back to roughly where they were.

Key Exemptions Traders Need to Know
Not everything gets hit at 15%. The White House fact sheet exempts critical minerals, metals, and energy products. CUSMA-compliant goods from Canada and Mexico also get a pass. That means CL and NG traders won't see direct tariff impact on energy imports, but the broader inflationary pressure from a 15% duty on everything else is real.

The 150-Day Clock Is the Real Story
These tariffs expire automatically in 150 days -- around mid-July -- unless Congress acts. Meanwhile, USTR Jamieson Greer announced accelerated Section 301 investigations into "most major trading partners." The play is clear: use the temporary authority as a bridge while building a more legally durable framework through Section 301.

For the UK, this is particularly painful. They thought their trade deal locked in a 10% rate. But the uniform application requirement means everyone pays 15% -- no special deals.

What Traders Should Watch

• Sunday night futures open -- Friday priced in 10%. The 15% rate hasn't been digested yet.
• Import-heavy sectors -- Retailers, auto manufacturers, and consumer goods companies take the biggest hit
• Treasury yields -- The 10-year jumped to 4.09% Friday. More inflation pressure could push it higher
• DXY at 4-year lows -- How the dollar reacts to higher duties in a weakening growth environment is the macro question
• The 150-day countdown -- July expiration creates a defined risk window. Every Congressional action on extension becomes tradeable

Between this tariff escalation, Nvidia earnings Wednesday, and the Iran situation, this could be one of the most event-dense weeks of 2026.
