https://en.wikipedia.org/wiki/2026_Cuban_crisis: “ The United States began blocking oil tankers heading to Cuba in February 2026, targeting companies such as the Mexican state-owned Pemex and threatening the responsible countries with tariffs should they resist. […] On 29 January 2026, Executive Order 14380 was signed and entered into force on 30 January, declaring a national emergency in US and authorizing the imposition of additional tariffs on imports into the United States from countries that directly or indirectly supply oil to Cuba.”
That’s a bit more than an embargo.
