Global Financial System

Ever wondered why a crisis on Wall Street can impact your job prospects here in Australia? The global financial system is the interconnected network of banks, markets, and institutions that move money across countries in seconds, linking economies together. Learning how Australia plugs into this system helps you understand real economic forces—from exchange rates affecting prices you pay, to international investments shaping local employment and growth.

Learning objective: Explain how the global financial system works and its impact on Australia.

By the end of this lesson you can:

I can describe the key institutions of the global financial system.
I can explain how exchange rates affect the Australian economy.
I can analyse the causes and consequences of the 2008 Global Financial Crisis.

Global finance is a spider web of money. Money flows instantly between countries; a shock in one place can shake the whole web (like 2008).

The global financial system

KEY INSTITUTIONS:
• IMF (International Monetary Fund): emergency lending; macroeconomic surveillance; stabilise currencies.
• WORLD BANK: development loans to developing nations; poverty reduction.
• WTO (World Trade Organisation): rules-based global trade; dispute resolution.
• BIS (Bank for International Settlements): "central bank of central banks."
• FEDERAL RESERVE (USA), ECB (Europe), RBA (Australia): major central banks.

EXCHANGE RATES:
• Price of one currency in terms of another.
• FLOATING: set by supply and demand (Australia since 1983).
• IMPACT ON AUSTRALIA:
– AUD rises: imports cheaper (good for consumers); exports dearer (bad for exporters).
– AUD falls: exports cheaper (good for miners, farmers); imports dearer (inflationary).
• RBA doesn't usually intervene; extreme cases only.

THE 2008 GLOBAL FINANCIAL CRISIS (GFC):
• CAUSE: US housing bubble collapsed. Subprime mortgages (given to people who couldn't afford them), bundled into complex securities (CDOs, CDSs), sold globally. When US house prices fell → securities worthless → bank failures.
• LEHMAN BROTHERS COLLAPSE (Sep 2008): shock to global financial confidence.
• CONTAGION: global credit markets froze → world recession.
• AUSTRALIA: Kevin Rudd government spent $42B in stimulus; Australia avoided technical recession — one of very few developed nations to do so.
• LEGACY: Basel III regulations; higher bank capital requirements; Dodd-Frank Act (USA).

FINANCIAL GLOBALISATION — RISKS:
• CONTAGION: one country's financial crisis rapidly spreads globally.
• CAPITAL FLIGHT: investors pull money from emerging markets in crises.
• TAX HAVENS: multinational profit-shifting reduces tax revenue for governments.
• CURRENCY MANIPULATION: countries devalue currency for trade advantage.

AARI TIP: Ask Aari to explain what "contagion" means in a financial context and how Australia was protected in 2008.

Exchange rate effects

AUD up → imports cheaper: Good for consumers buying overseas goods/travel.
AUD down → exports competitive: Good for mining, agriculture, tourism income.
RBA rarely intervenes: Floating rate adjusts automatically to economic conditions.

Quick reference

| Concept | Meaning |
|---|---|
| Exchange rate | Value of AUD vs other currencies |
| Global financial crisis | 2008 banking collapse |
| Capital flows | Investment across borders |
| Central banks | Manage money supply |
| Interdependence | Shocks spread |

Worked example (Medium)

Why did Australia avoid a recession during the 2008 Global Financial Crisis?

Banking exposure. Australian banks had relatively limited direct exposure to US subprime securities — tighter banking regulation and more conservative lending practices. The Big 4 banks remained profitable.
China demand. Australia's resource exports (iron ore, coal) remained in strong demand from China, which ran its own massive stimulus program ($586B) — keeping Australian commodity exports elevated.
Fiscal stimulus. The Rudd government rapidly deployed $42B in stimulus (cash payments, school buildings, insulation) — among the fastest fiscal responses of any nation. Well-timed to support demand.
Monetary policy. RBA cut rates rapidly from 7.25% to 3% — significant stimulus margin available.

Answer: Australia survived the GFC through: sound bank regulation, China demand, rapid fiscal stimulus, and space for monetary policy. All four elements were necessary.

Worked example (Hard)

Analyse how the Australian dollar's depreciation from US$1.10 (2011) to US$0.63 (2023) affected different sectors of the Australian economy.

Export winners. Mining companies (BHP, Rio Tinto) benefited enormously. Iron ore sold in US dollars converts to more Australian dollars when the AUD is low. A $100/tonne iron ore price generates A$91 at parity (AUD=1.10) but A$159 when AUD=0.63. Tourism also benefits — Australia becomes a cheaper destination for international visitors.
Import losers. Businesses importing machinery, technology and manufactured goods face higher costs. Consumers pay more for imported electronics, clothing and fuel (priced in USD). This contributes to cost-push inflation, as imported input costs flow through to domestic prices.
Education sector. International education (Australia's 4th largest export) benefits from a lower AUD — tuition and living costs become cheaper for overseas students in their home currency, increasing demand.
Overall assessment. The AUD acts as a natural "shock absorber": it falls when commodity prices fall (softening the blow for exporters) and rises when the economy is strong. This automatic adjustment is a key benefit of the floating exchange rate system Australia adopted in 1983.

Answer: AUD depreciation creates winners (exporters, tourism, education) and losers (importers, consumers) — the floating rate acts as an automatic stabiliser for the economy.

Common mistakes

Saying a falling AUD is "bad for the economy" A lower AUD has both positive and negative effects. It helps exporters and import-competing industries while hurting importers and consumers. The net effect depends on Australia's trade structure. Fix: Always discuss BOTH sides: "A falling AUD benefits exporters (mining, agriculture, education, tourism) by making their products cheaper internationally, but increases costs for importers and contributes to inflation through higher import prices."
Confusing the GFC mechanism with its consequences Students often describe the GFC as "banks went bankrupt" without explaining WHY — the securitisation of subprime mortgages, credit rating failures and the freezing of interbank lending are the mechanisms. Consequences (recession, unemployment) are the results. Fix: Structure your GFC analysis as: CAUSE (subprime lending + securitisation) → MECHANISM (CDO collapse → credit freeze → bank failures) → CONSEQUENCES (recession, unemployment, bailouts) → RESPONSE (stimulus, regulation).

Financial contagion — how a crisis in one country becomes a crisis everywhere

The 2008 Global Financial Crisis demonstrated a terrifying feature of the modern financial system: contagion — the rapid spread of financial crises across borders. Understanding how contagion works reveals why global financial regulation matters.

The mechanism: Modern banks don't just lend and borrow locally — they trade complex financial instruments globally. When US housing prices collapsed, the collateralised debt obligations (CDOs) bundled from US mortgages were held by banks in Germany, Iceland, the UK, France and beyond. When CDO values collapsed, these banks faced enormous losses. Because banks also lend to each other (interbank lending), the failure or suspected weakness of one bank made other banks reluctant to lend — freezing credit markets globally.

Speed: In previous financial crises (1930s), contagion spread over months as trade declined and currencies collapsed. In 2008, contagion was almost instantaneous because financial markets are connected electronically. Lehman Brothers collapsed on a Monday (15 September 2008); by Friday, credit markets had frozen across Europe and Asia.

Australia's relative protection: Australia's banks had limited direct exposure to US subprime securities (tighter regulation prevented the worst lending practices), China's massive stimulus maintained demand for Australian commodities, and the government's rapid fiscal response cushioned domestic demand. These factors combined to make Australia one of the very few developed nations to avoid recession.

Lessons: The GFC led to Basel III regulations requiring banks to hold more capital, and stress testing to simulate crisis scenarios. But the fundamental interconnectedness of global finance means contagion risk remains — the question is not whether another crisis will occur, but when and how well prepared institutions will be.

Practice questions

When the Australian dollar falls in value, it most directly benefits:
1. Australian consumers buying imported goods.
2. Australians travelling overseas.
3. Australian exporters like iron ore miners and farmers.
4. Australian businesses importing machinery.
