Warfare by Other Means: Economic Statecraft as Fifth-Generation War

A research position. Present-all-sides, sourced, neutral in voice. States and institutions are the actors; characterizations (“weaponized,” “siege,” “economic warfare”) are attributed to whoever made them, never adopted as fact. The companion instrument-by-instrument tracker is the live Economic Statecraft Tracker; the kinetic edge of this spectrum is The Drug War Goes Kinetic.

“Fifth-generation warfare” is a loose, contested label, so start with what is not contested: the dominant instruments of great-power conflict in the 2020s are not armies. They are the payment rail, the sanctions list, the tariff schedule, the export-control entity list, the subsidy, and — at the far end — the designation that turns a criminal problem into a lawful target. These are non-kinetic, deniable, scalable, and slow; their payload is an effect (a frozen reserve, a severed bank, a collapsed currency, a dependency) rather than captured ground. Call that fifth-generation warfare or call it economic statecraft; the mechanism is the same, and it is the through-line under the drug war, the immigration fight, the chip war, and the currency contest all at once.

Two organizing observations run through every instrument below. First, they form a spectrum, from the soft (a tariff, a subsidy) through the hard (a reserve freeze, a correspondent-banking cutoff) to the kinetic (a boat strike, an invasion) — and a state climbs the spectrum as the softer rungs fail. Second, they are competing ratchets: the US, China, and the BRICS bloc each run a different method of monetary and economic control, and — the key dynamic — the exercise of one state’s capability is what builds the counter-capability in the others. The freeze of Russia’s reserves in 2022 is the cleanest example: it proved the dollar rail is a weapon, which is precisely why every non-aligned treasury started building an exit. Warfare by other means is still an arms race; it just leaves the bodies off the front page.

Instrument 1 — Currency and the payment chokepoint

The foundational instrument is control of the money itself. Because global trade still clears in dollars, a dollar payment briefly transits a US correspondent bank, briefly enters US jurisdiction, and becomes actionable to a single sub-cabinet agency — the Office of Foreign Assets Control (OFAC), which administers the sanctions programs and publishes the SDN (Specially Designated Nationals) list. That is how a domestic office acquires global reach: secondary sanctions threaten any non-US bank’s access to dollar clearing and US correspondent accounts, and “without those accounts, a foreign bank cannot clear US dollars” (CNAS). The payment-freeze research calls this “the largest off-switch in the world without a CBDC” — de-facto programmable money for every non-American, no digital currency required.

The 2022 escalation was the reserve freeze: roughly $300 billion of Russian central-bank reserves frozen after the invasion, and seven Russian banks cut from SWIFT (OMFIF). The freeze, not the SWIFT cut, was the harder blow — it converted “reserves” from money into hostages, and signalled that no holder is too big to sanction. (SWIFT itself is Belgium-based; the messaging cutoff is a coalition lever, distinct from the US dollar-clearing lever — worth keeping separate.)

Instrument 2 — Sanctions as siege

Sanctions are the currency chokepoint aimed at a target. The Russia program is the largest in history — over 4,000 designated persons and entities, against a pre-2022 baseline that averaged about 815 new designations a year (CNAS 2024 Year in Review). By late 2025 the instrument had gone kinetic-adjacent: the US declared a blockade on sanctioned tankers in and out of Venezuela (17 December 2025) and began boarding and seizing shadow-fleet vessels, which the Atlantic Council flatly called “economic warfare meets gunboat diplomacy” — the establishment naming the frame out loud.

The defense, at full strength: sanctions are coercion short of war; the “smart/targeted” doctrine designates named individuals and entities rather than embargoing a population, precisely to spare civilians; a state that cannot freeze a criminal’s or an aggressor’s accounts is not restrained, it is disarmed.

The critique, kept for balance: a 2025 Lancet Global Health study estimated unilateral sanctions associated with roughly 564,000 deaths a year, the effect strongest for unilateral, economic, and US sanctions, and found no statistical effect for UN (multilateral) sanctions (Lancet Global Health). (Present that as the study’s finding, not settled fact: its lead authors are long-standing sanctions critics — attribute it, and pair it with the targeted-sanctions defense.) And the “does it work” literature is itself a fight: the standard reference codes about 34% of sanctions episodes as successful; Robert Pape’s re-coding, isolating sanctions from accompanying military force, put it nearer 5% (CEPR). The 34% number is the one that appears in ministerial speeches.

Instrument 3 — Tariffs and trade coercion

Tariffs are the trade instrument, used two ways at once: as coercion (leverage over other states on non-trade demands — fentanyl, migration, deficits) and as reindustrialization (protection to rebuild domestic production). The 2025 regime tried to do both through emergency powers, and the courts said no. Trump invoked the International Emergency Economic Powers Act (IEEPA) to impose the February 2025 “drug-trafficking” tariffs on Canada, Mexico, and China and the April 2025 “Liberation Day” reciprocal tariffs — and on 20 February 2026 the Supreme Court struck them down 6-3 (Learning Resources v. Trump), holding that IEEPA’s power to “regulate importation” cannot bear a taxing power; tariffs are “different in kind, not degree” (Bracewell; Tax Foundation). Roughly $160 billion in duties had been collected; the tariffs had been projected to raise $1.4 trillion over a decade.

The instructive part is what survived. Section 232 (national-security) and Section 301 (unfair-practices) tariffs were never challenged and remain in force — steel and aluminum, autos, copper, and a 25% semiconductor tariff effective January 2026 — with the administration running about a dozen new Section 232 investigations. As the US Trade Representative put it, “the policy hasn’t changed; the legal tools that implement it may change” (Miller Nash). That is a ratchet in miniature: strike one statutory authority and the instrument migrates to another. On the treaty side, the US declined to renew USMCA “in its current form” at the July 2026 joint review, triggering annual reviews to 2036 and separate bilateral tracks with Mexico and Canada (White & Case) — a review clause converted into a standing leverage machine.

The framings are old. Smoot-Hawley (1930) is the cautionary archetype (world trade fell some 60% in its wake — a characterization broadly held, with Cato’s caveat that it worsened rather than caused the Depression). The academic frame is Farrell and Newman’s “weaponized interdependence”: a state with jurisdiction over a central network hub coerces through chokepoint and surveillance effects — the theory that unites tariffs, sanctions, and export controls as one instrument family.

Instrument 4 — Export and compute controls

The export-control entity list is the instrument aimed at a rival’s capability rather than its cash. The US chip-export controls — restricting advanced logic chips and lithography to China — are arguably the most consequential economic-statecraft instrument in existence, because they decide who can build frontier AI at the hardware level. Because that instrument sits at the seam of economic and AI policy, it is documented in full on the AI Governance Tracker and the AI governance research rather than duplicated here; the point for this page is only that it belongs on the same spectrum — a chokepoint on the physical substrate of the next economy.

Instrument 5 — Industrial policy and reindustrialization

If sanctions and tariffs are the outward-facing instruments, industrial policy is the inward-facing one: the state directing capital to rebuild the productive base a rival is out-producing. The turn is real and bipartisan-ish in mood, if not in toolkit. National Security Adviser Jake Sullivan’s April 2023 Brookings speech explicitly repudiated the neoliberal free-trade consensus (the “New Washington Consensus”); the intellectual precursor is the financialization critique (Rana Foroohar’s Makers and Takers, 2016 — finance “making money from money” while manufacturing starved), and the liberal wing is the “abundance” discourse (Klein and Thompson, 2025 — the constraint on building is self-imposed proceduralism, not scarcity).

The instruments diverge sharply by administration, which is why this should be read as one turn with two rival toolkits, not one program: the 2022 stack was subsidy-and-credit (the CHIPS Act’s $52.7B with a 10-year bar on advanced-chip expansion in China; the IRA’s manufacturing credits), while the 2025-26 stack is tariff-plus-equity-stake: a proposed sovereign wealth fund (EO February 2025), and — the sharpest departure — the US government converting Intel’s unpaid CHIPS grants into a ~9.9% equity stake ($8.9B, August 2025), with reported stakes in five public companies by year-end (CNBC; Intel 8-K). Meanwhile the July 2025 One Big Beautiful Bill Act began unwinding the IRA’s clean-energy leg — industrial policy giveth and taketh.

The honest ledger includes the gap between announced and materialized: semiconductors lead reshoring with $640B+ committed across 140+ projects, yet US semiconductor-manufacturing employment fell from about 401,000 (2023) to 368,400 (early 2026), hiring lagging announcements by a year or two (IndustrialSage). Present all sides: proponents (Cass/American Compass on the right, Tucker/Roosevelt on the left) argue the state has a duty to structure the economy for resilience; critics (Cato, AEI’s Lincicome) invoke the Hayekian knowledge problem — “for every South Korea there is a Brazil” — and Senator Warren attacked the Intel deal from the left as socializing risk without control. The financialization critique cuts across left and right, which is itself the finding.

Instrument 6 — The kinetic edge

The spectrum’s far end is force, reached when the softer instruments are judged to have failed. The 2025-26 drug war is the case study: a Foreign Terrorist Organization designation of the cartels (February 2025) → a “non-international armed conflict” and “unlawful combatant” finding → at-sea strikes killing 200-plus, the invasion of Venezuela and capture of its president, and a domestic material-support authority. That is documented in full in The Drug War Goes Kinetic; the point here is structural — the economic and the kinetic are one spectrum, and the same designation that freezes a cartel’s assets is what authorized the boat strike. The siege and the raid are the same instrument at different settings.

The competing ratchets: three grids, three pawls

Economic statecraft is not one grid but three in competition, each a different method of monetary control with a different pawl — the tooth that stops it slipping back.

• The US grid — dollar hegemony + sanctions + stablecoin export. Pawl: network effects, the depth and safety of the Treasury market, and control of the messaging and clearing chokepoints. The 2025 twist is the GENIUS Act (signed July 2025): dollar stablecoins must be backed 1:1 by cash and short-term Treasuries, which manufactures new Treasury demand and exports dollar dominance to retail users abroad while deliberately foreclosing a US retail CBDC. The Treasury Secretary said outright it “buttresses the dollar’s status as the global reserve currency” (Treasury). The US ratchets via demand for its debt.
• The China grid — digital yuan + CIPS + state capitalism. Pawl: state control of the rail itself (the programmable, surveillable e-CNY) plus Belt-and-Road trade dependencies. Real infrastructure, growing fast, sanctions-resistant by design — but capped: CIPS still rides ~80% on SWIFT messaging, and the renminbi’s reserve share peaked around 2022 and fell to ~2.1%, overtaken by the Australian dollar (CSIS). China controls the plumbing but cannot yet make anyone want to hold the currency. It ratchets via control of the pipe.
• The BRICS grid — gold + bilateral local-currency deals + exit optionality. Weakest pawl: the bloc is too heterogeneous (India–China rivalry; Gulf states hedging toward Washington) to agree on a shared instrument. No BRICS currency exists — Kazan 2024 produced a mock banknote, and Putin has walked it back (“no need for haste”). What is real is gold: central banks bought over 1,000 tonnes for three straight years, and 76% expect gold to grow as a reserve share while 73% expect a smaller dollar role (World Gold Council). Its product is not a currency but exit insurance. It ratchets via optionality.

The sober synthesis: measurable de-dollarization is slow, real in gold, negligible in the renminbi, and — in the headline reserve number — substantially driven by exchange-rate valuation rather than central banks fleeing the dollar (IMF, “stealth erosion”). The infrastructure is being built faster than the dollar is being abandoned — capacity ahead of migration. Barry Eichengreen’s line still holds mostly: the dollar dominates “by default,” for want of an alternative safe asset — though even he now grants the alternatives are “starting to exist.”

Where it converges

The instruments are one family, the grids are one contest, and the dynamic is one arms race. The freeze of Russia’s reserves was the shot: it demonstrated the dollar rail is a weapon, and the Treasury Secretary conceded the blowback in her own words — “the more sanctions the US imposes, the more countries will seek financial transaction methods that do not involve the US dollar.” That is the fifth-generation-warfare signature in a sentence: the exercise of a capability calls the counter-capability into being. Every sanction strengthens the case for CIPS; every tariff-by- emergency-decree that the courts strike drives the instrument to a sturdier statute; every chip control accelerates the rival’s domestic fab program; every stablecoin rule that manufactures Treasury demand is answered by another tonne of central-bank gold.

None of these instruments is new. Tariffs, sanctions, export controls, industrial policy, and gunboat diplomacy all predate the term “fifth-generation warfare” by centuries. What is new is that they have become the primary theater — that great powers now fight mostly through the payment rail, the entity list, and the subsidy, escalating to force only at the edge, and that the whole apparatus is a set of interlocking ratchets whose teeth are the standards, the chokepoints, and the lists, not the coalitions. It is warfare, waged where the receipts are financial and the casualties are deniable. The bodies are still there. They are just harder to photograph.
