Sanctions, Platform Bans, and the New Doctrine of Information Warfare

The pipe becomes the weapon

Every chapter in this series turns on the same question: who controls the channel that carries information, and what does that control let them do to an economy and to a rival power. Earlier chapters follow that control through the printing press and the state licensing of what could be published. This one follows it into a set of channels that carry no words at all: a payments-messaging network, a chip fabrication supply chain, and the recommendation code inside a mobile app. In the 2020s, governments learned that cutting a bank, a company, or a platform off from one of these channels moves value and power on a scale that used to require an army.

The instrument is administrative rather than military. A committee meets, a list is amended, an effective date is set, and a bank, a chipmaker, or a social platform finds itself unable to reach the customers, suppliers, or capital markets it relied on the day before. No border is crossed and no shot is fired, yet the economic effect can run into the tens of billions of dollars and the geopolitical effect can reshape a rival's room to maneuver for years.

Three cases from 2019 to 2024 show the pattern hardening into a repeatable practice rather than a one-off response. Russia's removal from the SWIFT payments network in March 2022, the United States' 2019 blacklisting of Huawei, and a 2024 US law forcing the sale of TikTok were each aimed at a different target and justified on different grounds, but each used the same lever: exclusion from a network the target could not replace on short notice. Reading the three together against Russia's own 2013 statement of strategy shows a doctrine, contested in its details, taking shape around that lever.

The economic and the geopolitical threads run together in every case in this article. A single administrative order, a SWIFT delisting notice, an Entity List amendment, a divestiture deadline, can move tens of billions of dollars in enterprise value and can also close or open a state's practical room to negotiate, borrow, or arm. That double effect, on the balance sheet and on the map at once, is what separates this decade's use of market access from an ordinary trade dispute, and it is why reading these actions together as one pattern, rather than as three isolated news stories, changes what they mean.

Cutting Russia out of the payment rails

SWIFT, the Society for Worldwide Interbank Financial Telecommunication, is not a bank and does not move money itself. Founded by a group of European and American banks in 1973 to replace the telex machine, it is the standardized messaging network that instructs one bank to pay another, and it carries the instructions behind most international transfers. Being cut off from it does not freeze a bank's assets, but it forces that bank back onto slower, costlier, and far less trusted channels to move money across a border at all.

On 26 February 2022, two days into the invasion of Ukraine, the European Union, the United Kingdom, Canada, and the United States issued a joint statement naming SWIFT exclusion as a coming measure. On 2 March 2022 seven Russian banks, VTB, Bank Otkritie, Novikombank, Promsvyazbank, Bank Rossiya, Sovcombank, and VEB, were formally named for removal, effective 12 March 2022. The European Commission put the combined weight of those seven banks at 70 to 80 percent of the Russian banking system, a figure that made the measure the broadest financial exclusion action taken against a major economy in the SWIFT era.

The exemptions matter as much as the exclusions. Sberbank and Gazprombank, the two banks that clear most of Russia's oil and gas export payments, were deliberately left connected, because the EU still depended on Russian energy and cutting those payment channels would have blocked its own imports. The action freed the sanctioning governments from having to negotiate bank by bank, but it also exposed the limit of the lever: even the most sweeping payments cutoff on record stopped short of the two banks whose exclusion would have hurt the people imposing it.

SWIFT had disconnected a national banking system once before, when Iranian banks were cut off in 2012 over the country's nuclear program, but that action involved a smaller and less internationally connected economy. Applying the same tool to seven of Russia's largest banks at once, in a country far more integrated into global trade and energy markets, was a different order of action, and Western officials described the move at the time as intentionally without precedent.

Blacklisting a rival's chip supply: Huawei and the Entity List

The United States runs its own version of the same lever through the Commerce Department's Entity List, a roster of foreign organizations that American companies may not sell certain technology to without a special license. On 16 May 2019 the department's Bureau of Industry and Security added Huawei and 68 affiliated companies to that list, a single administrative act that cut the world's largest telecom-equipment maker off from the American chips, software, and components its handsets and network gear depended on.

Huawei reported the effect directly. Total 2019 revenue still reached roughly 858.8 billion yuan, about $123 billion, but the company said the blacklisting produced a $12 billion shortfall against what that year would otherwise have brought in, with its smartphone division absorbing most of the loss. The gap widened as the rules tightened: a May 2020 measure barring any foundry that used American chipmaking tools from supplying Huawei took full effect through 2021, a year in which the company's global smartphone shipments fell by more than 81 percent.

The lever cuts both directions. When Washington expanded its export controls again in October 2022 to restrict the sale of advanced chipmaking technology to China, the American equipment maker Lam Research warned it could lose up to $2.5 billion of its own revenue as a direct result. A control built to weaken a rival's capacity also weakens the domestic suppliers whose customers sit on the other side of the new line, and the size of that domestic cost is itself a rough measure of how tightly the two economies had grown together before the line was drawn.

The Huawei action did not stand alone. It arrived alongside a wider American effort to slow China's access to advanced semiconductor manufacturing, an effort that widened again in October 2022 and has continued through further rounds of export controls since. Chips sit at the base of nearly every other technology named in this article, from the servers that run an AI answer engine to the handsets Huawei could no longer fully supply, which is part of why control over their supply chain became a target this early and this precise.

TikTok and the algorithm as a sovereign asset

A platform ban runs the same lever in a different direction. Instead of excluding a rival's institutions from a market, it forces a rival's company to give up ownership of an asset already operating inside the sanctioning country. The Protecting Americans from Foreign Adversary Controlled Applications Act, signed into law on 24 April 2024, gave ByteDance until 19 January 2025 to sell TikTok's US operations or face a nationwide ban. ByteDance challenged the law and lost; the US Supreme Court upheld it in January 2025.

What made the case unusual was less the ban than the asset being valued. Former US Treasury Secretary Steven Mnuchin put TikTok's American business, including its recommendation algorithm, at close to $100 billion, a figure that treats a piece of software deciding what a hundred million people see next as comparable in worth to a large industrial company. That valuation carried its own contradiction: reporting at the time noted ByteDance could sell the app while stripping the algorithm out of the deal, which would sharply cut what a buyer was actually paying for and expose how much of the $100 billion figure sat in code that never had to leave Chinese hands.

The doctrine behind the moves

Russia gave the pattern a name nine years before SWIFT excluded its banks. In a February 2013 article titled "The Value of Science in Prediction," published in the military newspaper Voyenno-Promyshlennyy Kuryer, the chief of the Russian General Staff, Valery Gerasimov, argued that modern conflict increasingly runs through non-military means, political, economic, and informational pressure, at a ratio he put at roughly four to one against military measures. Western commentators folded that argument into a label, the Gerasimov doctrine, and used it to describe Russia's blend of cyber operations, disinformation, and economic pressure short of open war.

The label outran the argument. Mark Galeotti, the analyst most responsible for popularizing "Gerasimov doctrine" in English-language commentary, wrote in 2018 that he regretted coining it: Gerasimov's original article was a description and a forecast of how conflict was already changing, not a prescriptive plan Russia then adopted, and Russia has no single codified strategy that carries his name. The doctrine, read as an official Russian playbook, may not exist. The pattern it describes, states substituting economic and informational pressure for open war, plainly does.

The United States has built no equivalent document. It has, across administrations from both parties, assembled a set of tools that do the same work: an Entity List, a sanctions regime built around SWIFT access, an export-control system, and now a platform-divestiture law. Analysts at institutions including CSIS and the Council on Foreign Relations disagree about whether that set of tools amounts to a coherent US doctrine of economic and informational coercion or is better read as a series of separate trade-security and sanctions actions that happen to share a family resemblance. Unlike Russia's explicit, if since disowned, 2013 statement, no American official has put a name to a single strategy. The lever is used often enough to look intentional; whether it is doctrine or habit is not settled.

The Western response to Russia was itself a coordination exercise as much as a punishment. The EU, UK, Canada, and United States moved together and on a shared timeline, and the exemptions for Sberbank and Gazprombank were negotiated jointly rather than set unilaterally by any one government. That coordination is its own version of the logic Gerasimov described: allied governments substituting a synchronized economic and diplomatic response for a synchronized military one, four governments speaking as one committee rather than acting as four separate armies.

What the lever frees, and what it concentrates

Every instrument in this article was defended in the language of freedom. SWIFT exclusion was framed as freeing the international financial system from complicity in an invasion. The Huawei blacklist was framed as freeing American networks from a supplier the government judged a security risk. The TikTok law was framed as freeing American user data from a foreign parent company's reach. Each claim has a real basis, and none of the three actions was taken without public debate.

Each also concentrated a decision that used to sit with markets into the hands of a small number of officials. Whether a Russian bank can be paid, whether Huawei can buy a chip, and whether 170 million Americans can keep using an app their own choice put there, ended up decided by a sanctions committee, a licensing office, and a Congressional vote respectively, not by the customers or companies on either side of the transaction. That concentration is the cost side of the same ledger the freedom argument sits on, and both sides are true at once.

Companies on the receiving end of this decade have drawn the practical lesson. A bank, a chipmaker, or a platform that depends on a single payment network, a single foreign supplier, or a single national market for its ability to operate now treats that dependence as a named risk to manage, not a background fact of doing business. Diversifying suppliers, building redundant payment routes, and holding revenue across more than one jurisdiction are increasingly boardroom decisions rather than operational footnotes, a quiet economic legacy of a lever built for political use.

The pattern has one more implication this publication cannot avoid stating. The channels fought over here, payment messaging, chip supply, and app distribution, are pipes for money and code. A newer pipe, the AI answer engine that now decides which business gets named when a customer or investor asks a question, has not yet become an explicit front in this kind of contest. But the logic that removed seven banks from SWIFT and forced the sale of an app is the same logic that would apply if a government, or a platform itself, decided which companies an answer engine is permitted to cite. Nothing in the record here says that has happened. The lever exists in adjacent channels already, and its repeated use over the last five years is the reason to watch where it goes next, not to assume it.
