The Five Transmission Channels
- Currency crises cascade through debt repricing, margin calls, and forced liquidation
- US bond yield spikes reprice every risk asset on Earth within hours
- Energy shocks travel through inflation, margins, and consumption simultaneously
- Capital controls trigger panic selling in "similar" markets before controls spread
- Sovereign defaults create contagion through banking exposure and risk reassessment
The Earthquake You Don't See Coming
On March 9, 2022, at 3:47 AM London time, a single headline crossed the wires:
"LME SUSPENDS NICKEL TRADING AFTER 250% SURGE; CHINA'S TSINGSHAN FACING $8B MARGIN CALL"
— Bloomberg Terminal, March 2022
A nickel squeeze. One commodity. One Chinese company. Sounds contained, right?
Within 72 hours, the shockwave had traveled through:
This is how modern markets work. There are no isolated events. Every shock is a pebble thrown into a pond of interconnected pools. And the waves travel in ways that seem impossible — until you understand the mechanics.
What you're about to learn are the five primary transmission channels through which global shocks cascade across asset classes. These aren't theories. They're the engineering blueprints of financial earthquakes.
How Currency Crises Cascade Across Asset Classes
A currency crisis looks simple on the surface: a country's money loses value. But beneath that headline lies a cascade machine so powerful it can topple economies on the other side of the planet.
The Setup
Turkey, 2018. The lira has been weakening for months. Suddenly, President Erdogan picks a fight with the United States over a detained pastor. Sanctions loom. The lira crashes 40% in two weeks. But this is just the epicenter.
The Cascade Mechanics
The Currency Death Spiral
As the lira collapses, Turkish companies with dollar-denominated debt face instant bankruptcy. A loan that cost 100 million lira to service now costs 140 million. Banks start calling loans. Companies start selling assets — any assets — for dollars.
The EM Contagion
Global fund managers don't have time to analyze each emerging market individually. They see "EM" as one trade. When Turkey burns, they sell Argentina, South Africa, Indonesia — anything with the EM label. It's lazy, it's wrong, and it's reality.
The Credit Freeze
European banks have massive exposure to Turkish loans. Credit spreads blow out across Europe. Suddenly, Italian banks are being questioned. Spanish property developers can't refinance. The currency crisis has become a credit crisis.
The Equity Repricing
Higher credit spreads mean higher discount rates. Future cash flows are worth less today. P/E multiples contract across European equities. The S&P 500 "risk-off" rotation begins. Defensive stocks outperform cyclicals globally.
The transmission mechanism is brutally simple: currencies → debt → credit spreads → equity valuations → global risk appetite
Debt Channel
$250 billion in EM corporate dollar bonds. When currencies collapse, defaults spike. Default risk reprices credit globally.
Banking Channel
European banks hold $150B in Turkish loans alone. Their credit spreads widen, funding costs rise, lending contracts.
Risk Channel
VIX spikes. Risk parity funds deleverage. Momentum strategies reverse. The "risk-off" cascade begins.
"The lira crisis cost me money in Japanese equities. How? I still don't fully understand. But the P&L statement doesn't lie."
— Macro Trader, London, 2018
Why US Bond Yields Terrify Equity Traders
The 10-year US Treasury yield is the most watched number in global finance. Not because bonds are exciting — but because this single number reprices every risk asset on Earth.
The Mathematics of Terror
Every asset on Earth is valued using a discount rate. And for 90% of global assets, that discount rate starts with the "risk-free rate" — the US 10-year yield.
The DCF Equation
Stock Value = Future Cash Flows ÷ (Risk-Free Rate + Risk Premium)
When yields rise, stock values MUST fall. It's algebra.
Duration Damage
Growth stocks = Long duration assets. Their cash flows are far in the future — and get hit hardest by rate rises.
The Equity Risk Premium
When bonds yield 5%, why take stock risk for 7%? The competition for capital intensifies.
The 2022 Bond Massacre: A Case Study
In 2022, the 10-year yield surged from 1.5% to 4.2%. Here's what happened to every asset class:
The "4% Wall"
Many models treat 4% on the 10-year as a critical threshold. Above this level, bonds become genuinely competitive with stocks for the first time in 15 years. Every 25 basis point move above 4% forces billions in portfolio reallocation — away from equities.
The Global Transmission Belt
US yields don't just affect US assets. They're the gravitational center of global finance:
- Emerging Markets: Higher US yields attract capital away from EM. Their currencies weaken, debt costs rise, defaults increase
- Japanese Yen: The BOJ caps yields at 0%. As US yields rise, the yen collapses — 2022 saw USD/JPY hit 150
- European Periphery: Italian and Greek spreads widen as "safe haven" flows concentrate in US Treasuries
- Corporate Credit: High-yield spreads widen as the "risk-free" alternative becomes more attractive
"Don't fight the Fed" is wrong. The truth is: "Don't fight the 10-year." The Fed controls overnight rates. The 10-year controls your portfolio."

How Energy Shocks Travel Through Index Futures
Oil isn't just a commodity — it's an economic tax. When energy prices spike, the shock wave travels through every sector, every company, every portfolio simultaneously. But the path is more complex than "oil up, stocks down."
The Three Transmission Channels
The Margin Compression Channel
Energy is an input cost for 85% of companies. When oil spikes, airlines lose money immediately. Trucking companies can't raise prices fast enough. Chemical companies see feedstock costs explode. Margins compress → earnings fall → stocks drop.
The Consumer Demand Channel
When gas hits $5/gallon, that's $50-100/month less for everything else. Discretionary spending collapses. Retailers miss numbers. The "consumer is strong" narrative dies. Consumer discretionary sector tanks.
The Inflation → Fed Channel
Energy flows directly into headline CPI. Headline CPI drives Fed policy. Fed policy drives interest rates. Interest rates drive every asset on Earth. This is the longest but most powerful channel.
The 2022 Energy Cascade
Russia's invasion of Ukraine created the most complex energy shock in 50 years. Watch how it traveled:
The Invasion
Brent crude gaps from $95 to $105. Natural gas futures explode. European energy contracts go limit up. But this is just the physical commodity — the real cascade is beginning.
European Industrial Destruction
German chemical giants (BASF, Bayer) announce production cuts. European automakers halt lines. Fertilizer production stops. Agricultural futures spike. The industrial base of Europe is being repriced in real-time.
The Index Rotation
Quant funds and ETFs rotate hard: out of consumer discretionary, into energy. XLE (Energy ETF) surges 30%. XLY (Consumer Discretionary) drops 15%. The same indices are selling and buying simultaneously.
The Inflation Cascade
CPI prints 8.5%, 8.6%, 9.1%. The Fed pivots from "transitory" to panic mode. Rate hike expectations surge from 25bp to 75bp per meeting. The energy shock has become a monetary policy earthquake.
The Everything Selloff
The Fed hikes into economic weakness. Risk assets collapse globally. Crypto dies. SPACs die. Growth stocks die. The energy shock, filtered through monetary policy, has become a global asset destruction event.
"The war in Ukraine taught me that my tech stocks were really energy trades in disguise. Every asset is connected to every other asset through the energy web."

What Happens When Capital Controls Appear Overnight
Imagine waking up and discovering your money is trapped. The ATM won't let you withdraw more than $60. Wire transfers are blocked. Your brokerage account is frozen. This isn't a dystopian novel — it's happened in Cyprus, Greece, Argentina, and Lebanon within the last decade.
Emergency Capital Control Protocol
The Global Cascade Effect
When one country implements capital controls, the shockwave travels through a specific, predictable path:
Capital Control Contagion Map
The psychology is devastating: "If it happened there, it can happen here."
Phase 1: Preemptive Flight
Wealthy depositors in "similar" countries immediately start moving money. Argentina imposes controls? Brazilian wealthy start transferring to Miami.
Phase 2: Bank Stress
Deposit outflows force banks to sell assets. Asset prices fall. Banks need more capital. The doom loop begins.
Phase 3: Credit Freeze
Banks stop lending to each other. "What if they implement controls tomorrow?" Interbank markets seize. The crisis spreads through the financial plumbing.
Case Study: Russia, February 2022
The most comprehensive capital controls in modern history were imposed overnight:
- Foreign investors couldn't sell Russian stocks (trapped billions)
- Currency conversion banned (ruble became unconvertible)
- Bond payments blocked (technical defaults on sovereign debt)
- Stock exchange closed for a month
The cascade effect:
Index Deletion
MSCI removed Russia from its Emerging Markets index at effectively zero price. $40 billion in "value" vanished overnight. EM funds took massive losses.
Counterparty Fear
European banks with Russian exposure saw their stocks crater. Questions emerged: "Who else is exposed?" Credit spreads widened across European financials.
The "Investability" Question
Investors started questioning all authoritarian regimes. "Could China do this?" Premiums emerged for "rule of law" jurisdictions. A silent repricing of geopolitical risk began.
"After Russia, I added a 'capital control risk premium' to every emerging market position. It's an unquantifiable risk — but it's very real."
— EM Fund Manager, London, 2023
How Sovereign Defaults Spread
A country defaults on its debt. It sounds like a local problem. But sovereign defaults are nuclear events in the financial system — and the fallout spreads through three distinct radiation paths.
The Three Radiation Paths
Banking Sector Exposure
Banks hold sovereign bonds as "risk-free" capital. When Greece defaulted, French and German banks faced capital holes. They stopped lending. Credit contracted across Europe. One sovereign default nearly collapsed the European banking system.
The "Who's Next?" Panic
Greece defaults → Markets immediately start pricing Portugal, Ireland, Spain, Italy. Spreads blow out. The mere FEAR of default becomes self-fulfilling as funding costs spike. This is the reflexivity death spiral.
FX & Commodity Chaos
Defaulting nations usually see their currency collapse (if they have one) or impose capital controls (if they don't). Trade partners get hit. Commodity importers face shortages. Supply chains break.
Case Study: The Greek Doom Loop
Greece 2010-2015 is the textbook example of how sovereign distress cascades:
The Discovery
Greece reveals its debt is far higher than reported. Investors panic. Greek bond yields surge from 5% to 12%. But this is still "just Greece."
The Contagion
Portugal and Ireland come under scrutiny. Their yields surge too. The "PIGS" acronym is born. Suddenly this isn't a Greek crisis — it's a European crisis.
The Banking Link
French banks hold €50 billion in Greek bonds. German banks hold €40 billion. Their stock prices crater. Credit default swaps on major European banks spike 300%.
The ECB Intervention
"Whatever it takes." Draghi's three words prevent systemic collapse. But not before €3 trillion in European equity market value has been destroyed.
The Permanent Repricing
European periphery will never trade like Germany again. A permanent risk premium is embedded. Greek 10-year yields remain 100-200bp above German bunds forever.
The Doom Loop Dynamic
Banks hold government bonds. Government guarantees banks. When bonds fall, banks weaken. When banks weaken, government creditworthiness falls (bailout liability). Bond prices fall more. Banks weaken more. This reflexive spiral is why sovereign defaults can bring down entire financial systems.
"I used to think 'risk-free rate' meant something. After Greece, I realized even sovereign bonds carry credit risk. The only truly risk-free asset is knowing how risks propagate."
— Fixed Income PM, Frankfurt, 2015
When Multiple Shocks Collide
The real danger isn't any single shock. It's when multiple transmission channels activate simultaneously. 2022 gave us a masterclass:
- Energy shock (Russia invasion) → Commodity prices explode
- Inflation cascade (energy + supply chains) → CPI hits 9%
- Bond yield surge (Fed response) → 10-year from 1.5% to 4.2%
- EM currency crisis (dollar strength) → Dozens of EMs under pressure
- Capital controls (Russia) → $300B in frozen assets
- Near-default (Sri Lanka) → Proof the system is fragile
Every channel was active. Every transmission mechanism was firing. The result? The worst year for balanced portfolios since 1931.
The Hierarchy of Shocks
Not all shocks are created equal. Here's how they rank by global market impact:
The hierarchy matters because it tells you where to look first. When shocks collide, US rates dominate. Everything else is secondary.
The Shock Mechanics Playbook
Understanding how shocks propagate is only useful if you can act on it. Here's the framework:
Map the Transmission Channels First
Before trading any shock, ask: "How does this travel?" Currency → debt → credit → equities. Energy → inflation → Fed → rates → everything. Know the path before you bet on the outcome.
Trade the Second Derivative
The obvious trade gets crowded. The smart trade is one step removed. Oil spike? Don't buy oil — buy fertilizer companies before the agricultural cascade hits.
Watch the Speed of Transmission
Some channels transmit in minutes (FX markets). Others take months (corporate margins). Position sizing should reflect time-to-impact.
Fear the "All Channels Active" Scenario
When multiple shock types hit simultaneously, correlations go to 1. Diversification fails. Only cash and short positions survive. Recognize this pattern early.
Contagion Is Mostly Psychological
Markets don't wait for economic linkages. They anticipate. "Similar" countries get sold before any real transmission occurs. Trade the psychology, not just the economics.
The Fed Is the Circuit Breaker
Almost every cascade eventually runs into the Fed. "Whatever it takes" moments end panics. But they don't prevent the damage — they just cap it. Trade accordingly.
The Interconnected Reality
Here's the uncomfortable truth: there are no local crises anymore.
The Turkish lira affects your tech portfolio. Greek bonds affect your 401(k). Russian nickel affects your car payments. Everything is connected through channels most investors can't see.
The traders who understand shock mechanics have an edge that never expires. They see the earthquake before the buildings start shaking. They position for second-order effects while others are still processing first-order headlines.
"In a globally interconnected financial system, understanding transmission mechanics is more important than understanding any single asset. The crisis is never where it starts — it's where it travels."
— The New Reality
The next global shock is already forming somewhere. A currency is weakening. A bond market is cracking. An energy supply is tightening. A government is approaching default.
You now know how it will travel.
The only question is: will you be positioned for it?
