How to Think About Sanctions: Tools, Limits, and Unintended Outcomes

Sanctions Are Theater (Usually)

After Russia invaded Ukraine, the West imposed "unprecedented" sanctions. Freezing assets, SWIFT exclusion, oil embargoes. By every metric, this should have devastated Russia.

Instead, Russia's economy adapted. Inflation spiked, but didn't collapse. Investment fell, but domestic production increased. Two years in, the economy wasn't thriving—but it wasn't capitulating either.

This happens repeatedly. We sanction, declare victory, and wonder why the target country doesn't comply. The answer: we misunderstand how sanctions work.

The Mechanics of Economic Coercion

Sanctions assume a logic chain:

Economic Pain → Population Pressure → Leadership caves

But this chain breaks in practice:

1. What the West Controls

The West doesn't control the global economy—it controls access to Western markets, finance, and technology.

What works:

Oil/gas embargoes (scarce, hard to replace)
Semiconductor restrictions (nobody else makes cutting-edge chips)
Dollar exclusion (still the world's currency)

What doesn't:

Tariffs on manufactured goods (diverted to other markets, shifted to domestic production)
Banking restrictions (workarounds exist: shell companies, parallel banking systems)
Asset freezes on oligarchs (money's already hidden)

2. The Regime's Calculus

Leaders being sanctioned don't think like economists. They think like survivors.

Putin faced a choice: absorb sanctions or fail to expand Russian influence. He chose sanctions. Why? Because losing Eastern Europe was existential (in his view), and sanctions were just economic damage.

The math is different if you're choosing between:

A (Keep power + economic sanctions)
B (Lose power + no sanctions)

A is preferable. Most leaders in this position choose A.

3. The Diversification Response

Targeted economies develop workarounds:

Year 1: Panic, black markets, inflation
Year 2: Supply chain adaptation, alternative suppliers
Year 3: Domestic substitution, reduced living standards but stability

China, India, and Iran become sanctions-relief valves. Trade reroutes through intermediaries. Cryptocurrencies and barter systems bypass SWIFT.

After 60+ years of sanctions on Iran, the economy adapted. It's poor, but not collapsed. After decades of sanctions on North Korea, the economy is isolated but functional.

When Sanctions Actually Work

They work only under narrow conditions:

Prerequisite 1: Economic Interdependence

Sanctions against Switzerland in 1940 did nothing—Switzerland had diversified trade. Sanctions against South Africa in the 1980s worked partly because the global economy was critical to its economy.

Case: South Africa. Apartheid was economically entrenched. Sanctions reduced investment, raising the cost of maintaining the system. Combined with internal resistance, the regime eventually capitulated.

Prerequisite 2: No Alternative Suppliers

You can sanction semiconductors (TSMC has limited alternatives). You can't sanction oil effectively if Russia, Saudi Arabia, Iraq, and Venezuela exist.

Prerequisite 3: Regime Vulnerability

If the leadership is weak or fractured economically-imposed pain accelerates collapse. If it's consolidated, pain strengthens nationalistic resistance (rally-around-the-flag effect).

The Unintended Consequences

Weaponization of the dollar — Sanctions pushed Russia and China to develop payment systems outside SWIFT. Long-term, this weakens US financial primacy.
Regime consolidation — Pain unifies the population against the outside threat. Nationalism rises; dissent becomes unpatriotic.
Alliance shift — Sanctioned countries deepen ties with non-Western powers. Russia-China-Iran alignment strengthened post-2014.
Stagflation in sanctioning countries — Oil sanctions on Russia meant higher energy prices for Europe and the US.

The Hard Truth

Sanctions are best understood as punishment, not as policy tools that change behavior. They communicate: "We're serious about this."

But if your goal is behavior change, you need:

Negotiated off-ramps — A way for the target to change course without losing face
Targeted restrictions — Against decision-makers, not entire economies
Unity — Sanctions fail if major economies defect (China, India, UAE undermine Western restrictions)

Without these, sanctions become a way for democracies to feel they're "doing something" while authoritarian leaders consolidate control.

The as const pattern gives you the union type for free, works with Object.values(), and has zero runtime overhead.

These aren't magic tricks. They're small investments in type precision that pay dividends every time you refactor — which, if you're working on something real, is constantly.
