Key Idea: Topic 6.1 is about the geopolitical and economic risks that a deeply connected world creates. Its single micro, 6.1.1, runs on one core idea: The same global interactions that bind the world together — trade, finance, the internet, supply chains — are also the routes by which shocks travel. A risk is the chance of harm, and in a connected world risks become systemic: a failure in one country, market or network can cascade across the whole system. Four risks dominate: financial contagion (a 2008-style crisis through linked banks), supply-chain disruption (fragile just-in-time chains and narrow chokepoints), cyber-security threats (attacks on banks, grids and pipelines; data theft; surveillance), and technological disruption (automation and AI displacing jobs unevenly). This is HL-core content, examined on Paper 3 (HL only) — a synoptic, essay-led two-part question: a [12] structured part (Analyse / Examine) and a [16] markband essay (To what extent / Evaluate / Discuss). Synoptic links to power (Unit 4) and development (Unit 5) are rewarded.
🌐 6.1.1 — Why connection breeds risk
Connection brings huge gains — cheaper goods, faster information, shared knowledge. But every link is also a route for shocks to travel. The more tightly the world is wired together, the faster a local problem becomes a global one. That trade-off between efficiency and resilience is the heart of this topic: tight financial links, lean just-in-time stock and single sourcing all save money in calm times, but they remove the buffers that absorb shocks — making the system faster, cheaper and far more fragile at once.
Four risks global interactions create — and how they spread
| Type of risk | How it spreads through the system | Example (in own words) |
|---|---|---|
| Financial contagion | Banks, investors and markets are linked, so losses in one spread instantly to others | A wave of mortgage defaults in one country froze global lending in 2008, tipping many economies into recession |
| Supply-chain disruption | Long just-in-time chains pass a shock from one broken link to every factory downstream | When a giant ship wedged across the Suez Canal in 2021, billions in trade stalled and distant factories ran short of parts |
| Cyber-attack | Networks are connected, so malware or ransomware can leap between firms, countries and infrastructure | Ransomware that shut a major fuel pipeline forced a whole region's petrol stations to run dry for days |
| Technological disruption | New technology diffuses globally, displacing jobs and concentrating advantage in a few firms and places | Automation and AI can replace routine factory and office jobs faster than new work appears in some regions |
Key terms you must be able to use
- Geopolitical risk — the threat that conflict, sanctions, trade wars or unstable governments disrupt the flows of goods, energy, money and people between states.
- Economic / financial contagion — the way a shock (a banking crisis, a currency crash, a default) spreads from one market or country to others through their financial links.
- Supply-chain risk — the danger that production stops because a long, just-in-time chain is broken at one weak point (a factory, a port, a single supplier).
- Chokepoint — a narrow place a huge share of global trade must pass through, so a blockage there disrupts the whole flow (a strait, a canal, a major shipping lane).
- Just-in-time (JIT) — making and delivering goods only as needed, holding almost no stock — cheap and efficient, but fragile if any link fails.
- Cyber-security — protecting computer networks, data and infrastructure from attacks such as hacking, ransomware and data theft.
- Systemic risk — the risk that a failure in one part of a connected system brings down much of the rest, rather than staying contained.
💸 Financial & supply-chain risk (the [12] strand)
The economic half of the micro is the developed-factors part — usually an Analyse or Examine of how interconnection transmits financial shocks and how fragile long, just-in-time supply chains are. No For/Against debate is needed here: take three or four distinct mechanisms, develop each with a named example, then synthesise how efficiency was traded for resilience.
How financial & trade shocks transmit — with named cases
| Mechanism | How the shock travels | Named case (own wording) |
|---|---|---|
| Financial contagion | Linked banks and investors hold each other's debt, so one failure spreads losses and panic worldwide | 2008 — risky home-loan defaults in one country froze global lending and spread recession across continents |
| Just-in-time fragility | Firms hold almost no stock, so one broken link halts every factory downstream | A flooded factory or closed port can stall production far down the chain within days |
| Chokepoint dependence | A vast share of trade squeezes through a few narrow straits and canals; one blockage ripples worldwide | Suez Canal grounding (2021) stalled billions in east-west trade; the Strait of Hormuz threatens global oil if closed |
| Single-supplier over-dependence | Relying on one country or firm for a critical input concentrates risk in one place | Pandemic chip shortage halted carmakers worldwide when a few semiconductor makers stalled |
Tip: A [12] Analyse rewards developed mechanisms, not a long list. For each one: name it, explain how the shock travels, and pin it to a named example (2008, the Suez Canal, the Strait of Hormuz, the chip shortage). Then add a sentence of synthesis — how cheap efficiency created the fragility — to reach the top band.
🛡️ Cyber & new-technology risk (the double-edged strand)
The technological half is a genuine debate. New communications and digital technologies power global interactions, but they also create fresh cyber-security threats and economic disruption of their own — and the same technology often both creates and helps manage risk. Cyber-attacks reach inside banks, hospitals and power grids from anywhere; mass data collection and surveillance threaten privacy and even elections; and automation, AI and 3D printing displace jobs unevenly, hitting some places far harder than others.
Cyber & technological risk — and the same tools as the answer
| Strand | The risk it creates | How the same technology helps manage risk |
|---|---|---|
| Cyber-attacks on infrastructure | Ransomware and hacking can shut pipelines, hospitals, ports and grids across whole regions | Cybersecurity tools, encryption and biometric e-passports defend networks and borders |
| Data theft & surveillance | A single breach exposes millions to fraud; mass data lets states and firms monitor populations and spread disinformation | Secure systems, GIS and digital warning systems speed hazard response and disaster relief |
| Automation & AI | Robots and software replace routine factory and office jobs, cutting employment and tax revenue | Automation also raises productivity and creates new kinds of work — the net effect is not pure loss |
| Uneven impact by place | Gains concentrate in a few high-tech firms and regions; job losses fall on industrial towns and lower-skilled workers | Digital tools can extend services and warning to remote places — if connectivity exists |
Example: Creating risk: ransomware that shut a major fuel pipeline emptied petrol stations across a region for days, and large data breaches have exposed the personal details of hundreds of millions of people. Managing risk: the same technologies also defend — cybersecurity and biometric borders protect networks and states, while GIS and drones track hazards. Technology is both the source of new risks and part of the answer.

Why do global interactions create new risks? Every connection is also a route for shocks to travel. The more tightly the world is wired together, the faster a local failure — a bank, a port, a network — becomes a systemic, global problem. Efficiency is traded for resilience.
What is a chokepoint, and why does it matter? A narrow place (a strait, a canal) a huge share of world trade must pass through. One blockage there — like the Suez Canal in 2021 — disrupts the whole flow, stalling factories far downstream.
Name the four main risks global interactions create. Financial contagion, supply-chain disruption, cyber-attacks, and technological disruption (automation/AI displacing jobs unevenly).
Why is new technology 'double-edged' for risk? It creates risk (cyber-attacks, data theft, automation displacing jobs) but the same technology also helps manage risk (cybersecurity, biometric borders, GIS and drones for hazards). It is both source and answer.
What judgement do examiners reward on the greatest risk? No risk is greatest everywhere — it depends on scale, timescale and place; the greatest threat is the one a people or place is least able to absorb (resilience).

Exam Tips
- Connection = efficiency traded for resilience; every link is a route for shocks to spread.
- The four risks: financial contagion, supply-chain disruption, cyber-attacks, technological disruption.
- Chokepoints (Suez, Hormuz) + just-in-time chains make trade fast and cheap but fragile — name a real case for each.
- New technology is double-edged — it creates cyber and job-loss risks AND helps manage risk.
- The [12] Analyse rewards developed mechanisms with named examples + a synthesis — no For/Against needed.
- The [16] essay needs named current cases for each risk, a genuine comparison, synoptic links to power (U4) and development (U5), and a nuanced judgement ('depends on scale, timescale and resilience').
