President Donald Trump signed a Russia sanctions bill into law on Friday. The legislation [targets Russian officials, banks, the energy and defence industries, and the fleet of tankers that carries Russian crude outside established insurance and ownership structures](https://www.dw.com/en/trump-signs-broad-russia-sanctions-bill/a-79335115). It passed with wide bipartisan margins, [86 to 11 in the Senate and 262 to 159 in the House](https://www.usnews.com/news/world/articles/2026-09-18/trump-signs-russia-sanctions-bill-into-law).

The provision with the widest reach is not aimed at Russia at all. The law directs the president to impose tariffs of up to 100% on the five largest importers of Russian oil or natural gas, with an exemption for countries that buy comparatively little and are demonstrably reducing purchases. That places India, China and Turkey inside a US trade instrument based on their energy sourcing.

On the same day the State Department [cleared a $2.7 billion defence package for Ukraine](https://www.thehindu.com/news/international/us-state-department-clears-27-billion-ukraine-defence-package/article71483529.ece), to be funded by a combination of European contributions and US Foreign Military Financing appropriated during the Biden administration. Russian state media framed the week differently, with TASS publishing [its own calculation of what Kyiv will spend servicing and repaying state debt in 2027](https://tass.ru/ekonomika/28127749), an argument that Ukraine's financing model is the fragile part of the arrangement.

## What this means

Secondary measures of this kind rarely stop the oil from moving. They change who carries it, who insures it and what currency settles it, which raises the cost of every barrel and pushes trade further into non-dollar payment channels and opaque shipping. Refiners in India and Turkey face a direct choice between discounted Russian crude and US tariff exposure, while tanker owners outside the Western insurance system gain pricing power. Each round of this policy gives buyers another reason to build settlement infrastructure that Washington does not control.

## What to watch

- Whether the administration actually designates any of the five largest buyers, since the gap between the law's text and its enforcement determines how much trade is really rerouted.
- The discount on Russian crude relative to Brent, which shows whether the shipping and insurance squeeze is biting or being absorbed.
- Announcements of new rupee, yuan or dirham settlement arrangements for energy, the practical measure of how far buyers are moving outside dollar clearing.
