Who is affected and how:

• U.S. banks, broker‑dealers, and financial institutions: Must cut or screen transactions, block funds, restrict correspondent/payable‑through accounts, refuse transfers benefiting named Russian actors, and comply with fast regulatory deadlines—raising compliance costs and operational strain.
• Investment funds and investors (asset managers, hedge funds, mutual funds): Face explicit bans on buying Russian sovereign debt and investing in Russian government‑owned or controlled entities; they may need to divest existing holdings and change investment policies rapidly.
• U.S. exporters and importers (including energy companies): U.S. energy exports to Russia are banned; duties of at least 500% on Russian goods (and on goods from third countries that trade Russian energy) will disrupt supply chains and increase costs for importers and potentially U.S. consumers.
• Securities markets and listed issuers: The SEC must halt trading in securities of Russian‑government‑affiliated issuers, affecting holders of ADRs and related instruments and complicating custody and settlement operations.
• Russian state actors, SOEs, Rosatom and named banks: Targeted with blocking sanctions, asset freezes, visa denials, and trade restrictions that reduce financing and trade capacity.
• Foreign firms and governments that trade Russian‑origin energy or help expand Russian energy production: Exposed to secondary sanctions, high U.S. import duties, and prohibitions on U.S. transactions—creating incentives to cut Russia ties or face severe penalties.
• U.S. consumers and businesses: Could face higher prices for certain imports, potential disruptions to supply chains, and market volatility; trade partners may retaliate, affecting U.S. exports.
• Federal agencies and regulators (Treasury/OFAC, Commerce/BIS, SEC, USTR, DOJ): Must design and implement many rules and enforcement mechanisms quickly, requiring interagency coordination, new licensing guidance, and legal work.

Operational and legal risks:

• Rapid 15‑day deadlines and recurring 90‑day sanction reviews create significant administrative burdens and legal uncertainty for regulated entities.
• The 500% tariff floors and wide definitions of covered behavior risk trade disputes at the WTO and diplomatic frictions with allies and trading partners.
• Narrow exceptions (humanitarian, intelligence) limit some harms to civilians, but enforcement complexity will raise compliance costs and litigation risk.

Exit and conditionality:

• The President may suspend or lift measures only after certifying cessation of hostile acts and a verifiable peace agreement; immediate re‑imposition is required if covered actors return to prohibited conduct. This creates a conditional path for relief but substantial preconditions for rollback.
