The US has built a formidable arsenal of economic weapons—sanctions, export controls, SWIFT exclusion—that operate through chokepoints in global finance and trade. The dollar's dominance (60% of reserves, 90% of forex) combined with control of financial infrastructure lets America wage economic warfare more effectively than military force. The Iran case demonstrates how targeted pressure on banks, oil, and the central bank brought a nation to the negotiating table, though overuse risks pushing adversaries toward alternative systems.
Key Takeaways
Sanctions, export controls, SWIFT exclusion operate through financial chokepoints
USD = 60% of global reserves, 90% of forex transactions
Anyone touching dollars is subject to US jurisdiction
SWIFT, correspondent banking, clearinghouses all US-influenced
Can target specific banks, individuals, or entire countries
Companies/banks must choose: do business with Iran OR US
This amplifies sanctions pressure beyond direct targets
Pressure on banks, oil, central bank brought Iran to negotiate
Required decade of escalating pressure + strategic timing of relief
Countries seek alternative systems (China, Russia, crypto)
Must balance pressure with maintaining dependence on US system

Sanction on the central bank of Iran
17: Good cop, bad cop
Sanctions must succeed in shaping psychology of banks, companies, govts

New idea: Iran can still sell oil, but $ in escrow
18: Landslide
Inflation → bottom-up pressure for regime change
Landslide election in favor of better Int’l relations to reduce sanctions
19: The freeze
Diminishing marginal returns of additional sanctions
Sanction relief discussions
Unfrozen under $5B from escrow
Frozen nuclear program + economy
20: The world avoided another war
Loosening embargo’s at the right time allows US to maintain Iran’s dependence upon on it (rather than finding alt trade partners)
2+ weeks of deal negotiation for Iran nuclear deal
21: Black magic

This was the first time sanctions really worked
Globalism → US given economic choke points

Threatening sanctions, but none enacted
26: The contact group
G7 sanction advisory group
Memo writers: officials with lesser titles but more influence
27: The scalpel
Adding financial rigor (eg. from Goldman Sachs)

28: The opening salvo
Iran sanctions were unanimous, Russian sanctions hurt some US businesses
29: MH17
Russia downs plane that kills 200+ Europeans, turns up pressure for sectoral sanctions

Stalemate
35: Golden escalator
Sanctions were effective, but serious damage to economies and risk of overuse
Undermines US leadership in the global economy
Globalization fashioned into a weapon

Though ultimately, sanctions on Russia failed to end war
Uncertainty → incrementalism → ↑
Election interference: “you fuck with us over the election and we’ll crash your economy”
4: China’s bid for tech mastery
36: The interpreter
China recognized as an adversary, reorienting foreign policy as such
Huawei 5G on par with US reserve currency as economic + political kill switch with global reach
Belt & road initiative (BRI) quite controversial for US, but embraced by UK
New choke point: finance → tech
37: Irresponsible stakeholder
Huawei’s advantages:
Support from gov’t
Expertise from abroad
↑ China not playing by the rules, but not being punished for it
1990s China traumatic trifecta:
Tiananmen Square protests
Gulf War
Dissolution of the Soviet Union
↑ hide strength, bide time
False assumption that globalization would lead to economic freedom → democracy
Too gung-ho about adding to WTO without having it follow the rules
38: The awakening
Xis goal to become “the reddest leader”
Techno-authoritarianism
BRI debt trap diplomacy
Military civil fusion
Made in China 2025 frontier tech
More $$ spent on chips than oil
39: Let 100 China policies bloom
Trump worry over trade deficit: not understanding more US consumption
China’s modernization complete
40: The clue: ZTE
Tech dominance was clear key risk
Huawei + ZTE state risk
ZTE barred from all US purchases
Trump national security < China trade deal
Proof of large, sudden impact of tarrifs
41: The validation: Fujian Jianhua
Tit for tat escalation
FJ stealing trade secrets
Financial sanctions → commercial sanctions
42: The first shot at Huawei
Huawei exec arrest due to Iran sanctions violation
China WTO + predatory economic tactics → hollowed out industries
Massive subsidies, stolen IP, etc.
43: A false start
“The Middle East has oil, China has rare earths” DXP
Huawei re-allowed to buy from US companies via license applications
Huawei not thwarted - needed cooperation from more gov’ts
44: Backdoors and betrayal
US firms contributed 39% of value in semi supply chain, China 6%
Huawei hardware backdoor
But, UK continued relationship
45: The second shot at Huawei
US needed to offer a better alternative than Huawei
Covid
Huawei → US nuclear kill switch
FDPR: Huawei banned from US
46: The dominoes fall
Effective, $100Bs
China pledging $1.5T to tech self-sufficiency
Other countries followed shortly after
30% plummet
47: Iron curtain
False belief in China WTO → democracy
Reciprocity + candor
ASML chokepoint
Trump turned consensus on its head that China economic warfare would cause extreme harm
China threats were more bark than bite
Designed to be permanent, not temporary
5: Russia’s invasion of Ukraine
48: The practitioner
Invasion → new options in play
49: The best-laid plans
Trump imposed a record # of sanctions, but they were largely ineffective
Biden re-assessment of sanctions policies
50: America is back
Afghanistan disaster
51: Standing athwart history, yelling stop
Russia invasion prep
Advance warning, but still skepticism
52: Panic at the pump
Immediate inflation concerns (oil)
Europe echoed threats

Promising to weaponize finance + tech
Day zero sanctions
Financial sanctions + export controls
54: The Scholz jolt
Europe joined US in sanctions
55: Banks and tanks
Invasion → day zero sanctions
Russia oil, gas, coal exempted
56: Pandora’s box
Freezing Russia central bank’s USD reserves
↑ risks future status as world’s reserve currency
G7 counties sign-off
↑ unprecedented, “it was just theft”
57: Monetary policy at the point of a gun
Afraid of being poor stewards of world financial system

Estimated 10-15% GDP loss, wiping out 20 years of progress
58: A Potemkin currency
Ukraine holding off blitzkrieg
US, others start embargoing Russian oil
59: Supply & demand
Dipping into oil reserves for shock prevention
India purchasing Russian oil
60: The Rubik’s Cube
Oil sanction / tariffs
61: What other option do we have?
Price cap vs complete ban
Incredible existential risk of ban
EU committed to ↑
US urging for price cap
62: The service providers’ cartel
Price cap + secondary sanctions
63: An economic war of attrition
Sanctions changed from trying to influence Russian behavior to damage their economy
64: A partitioned market
Price cap threatens price setting dominance of OPEC+
Price cap possibilities:
Marginal cost of production ($10-25)
Russia gov’t budget (<$70)
Current increased cost ($55-65)
Consultation with buyers (conservative)
$30 vs $65-70 → $60
6mo later, profits down by 50%
6: The world economic rupture
65: Small yard and high fence
Chips export to China blocked by US
De-risking and diversifying, not decoupling
3 important tech families: biotech, clean energy, computing
66: The scramble for economic security
BRICS
67: Breaking the choke points
DM Libra crypto
Crypto breaks US economic warfare
USD reserve status is still strong
Even China’s trade is only 30% in its own currency
Other countries don’t like USD reserve dominance, but better than China
US should launch a digital currency
“China may well build deeper capital markets or even loosen capital controls, but it cannot match the fundamental advantages of the dollar unless it revamps its entire political system for the better or America’s is remade for the worse”
↑ careful of the Fed, legal system
Petrol dollar system
China is still 5+ years behind on chips
Could break the global economy
68: Strategy and sacrifice
Are the benefits of economic warfare worth the cost?
Fixed a fatal flaw in globalization, preventing underminers of US-led world order from profiting while doing it
G7 is the steering committee of economic warfare, BRICS is the counterweight
To deter Russia, threats of sanctions must’ve been conspicuously stronger
Conclusion: impossible trinity
Should create a permanent economic war council
A cross-disciplinary council of experts trained by curriculum and constantly working on sanction scenarios
Sanctions could also be used for
Carbon-intensive mega projects
Dangerous applications of AI
US must continuously improve economic arsenal
Eg. sovereign wealth fund, stockpiled resources, domestic investments
“The age of economic warfare”
The impossible trinity:
Economic interdependence
Economic security
Geopolitical competition
Eventually chokepoints will diminish in importance and the age will end
Unsure whether response to ↑ will be positive or negative
