10.1 The Global Adoption of Fiat Currency
Fiat currency dominates the global monetary system today. After the U.S. unilaterally broke the Bretton Woods Agreement, nations were forced to adopt fiat monetary systems where money derives its value from government decree and public confidence, rather than tangible commodities like gold or silver.
Key Fact:
- According to the International Monetary Fund (IMF), over 180 currencies are in circulation globally, all backed solely by government trust rather than commodities.
- Fiat currency relies entirely on confidence and fiscal discipline—its value can collapse if trust erodes.
Most nations rely on central banks to issue and regulate fiat currencies, centralizing monetary policy and enabling governments to expand the money supply as needed.
10.2 The Transition from the Gold Standard to the Dollar Standard and the Rise of the Petrodollar System
The collapse of the Bretton Woods Agreement in 1971 marked one of the most significant turning points in monetary history. It severed the link between the U.S. dollar and gold, replacing it with a system based on fiat currency and reliance on the U.S. dollar as the global reserve standard.
10.2.1 The End of the Gold Standard (The Nixon Shock)
- In 1944, the Bretton Woods Agreement established a global monetary system where the U.S. dollar was pegged to gold at $35 per ounce, and other currencies were pegged to the dollar.
- This system ensured stability by tying currencies to a tangible asset (gold), while giving the U.S. control as the issuer of the reserve currency.
- However, excessive U.S. spending on wars (Korea and Vietnam) and social programs (Johnson’s Great Society) led to deficits and an outflow of gold as foreign nations exchanged dollars for gold.
- By 1971, U.S. gold reserves had dwindled, and President Richard Nixon suspended gold convertibility, effectively ending the gold standard in what became known as the Nixon Shock.
- This move shifted the global economy to a fiat currency system, where the value of money depended solely on confidence and government backing rather than physical commodities.
Key Impact:
- The dollar became a floating currency, meaning its value fluctuated based on market forces rather than a fixed gold price.
- Nations could now print money without constraints, fueling debt expansion and inflation risks.
- The world economy shifted from commodity-backed stability to a system reliant on trust and central bank policies.
10.2.2 The Petrodollar Agreement (1974)
To maintain global demand for the U.S. dollar after abandoning the gold standard, the U.S. struck a deal with Saudi Arabia in 1974.
The Agreement:
- Saudi Arabia agreed to price oil exclusively in U.S. dollars and reinvest oil profits into U.S. Treasury bonds, providing liquidity for U.S. debt financing.
- In return, the U.S. provided military protection and political support for Saudi Arabia and its ruling monarchy.
The Birth of the Petrodollar System:
- Oil, the world’s most critical commodity, became dollar-denominated, cementing the dollar’s dominance in global trade and finance.
- Other oil-producing nations followed Saudi Arabia’s lead, further embedding the petrodollar system.
Consequences of the Petrodollar System:
- U.S. Dollar Hegemony: The system solidified the dollar as the global reserve currency, giving the U.S. unmatched influence over the international monetary system.
- Global Debt and Inequality: By enabling deficit spending and debt-financed growth, the petrodollar system fueled economic imbalances and wealth inequality.
- Energy and Military Power: Control over oil markets gave the U.S. geopolitical leverage, reinforcing its dominance through military alliances and interventions.
Key Insight:
Military dominance and energy dependence replaced gold backing as the foundation of U.S. financial power, enforcing the dollar’s role through force and economic influence rather than trust.
10.3 Alternative Reserve Currencies
The Euro (€): Introduced in 1999 as part of the European Monetary Union, the euro was designed to unify European economies and reduce reliance on the U.S. dollar. It is now the second-largest reserve currency, accounting for approximately 20% of global reserves.
The next closest currency is the EURO at 20%.
Emerging Alternatives: Other currencies like the Chinese yuan (CNY) have gained traction as reserve assets, especially among developing nations and trade partners seeking to reduce dependence on the dollar. China’s Belt and Road Initiative and trade agreements have further promoted yuan adoption.
10.4 Exchange Rate Systems
Fiat currencies are traded in foreign exchange (Forex) markets, where their values fluctuate based on supply and demand, economic performance, inflation rates, interest rates, and central bank interventions. Exchange rates play a critical role in international trade, investment, and financial stability.
Types of Exchange Rate Systems:
- Floating Exchange Rates:
- Definition: The value of the currency is determined by market forces without direct government or central bank intervention.
- Examples: The U.S. Dollar (USD), Euro (EUR), Japanese Yen (JPY), and British Pound (GBP) operate under floating exchange rate systems.
- Advantages:
- Adjusts automatically to economic conditions (e.g., inflation, trade deficits).
- Reduces the need for large foreign exchange reserves.
- Disadvantages:
- Can experience volatility, leading to uncertainty in international trade and investment.
- Highly sensitive to market speculation.
- Fixed (Pegged) Exchange Rates:
- Definition: The value of the currency is tied (pegged) to another currency, a basket of currencies, or a commodity like gold.
- Examples:
- Hong Kong Dollar (HKD): Pegged to the U.S. Dollar (USD) at approximately 7.8 HKD/USD.
- Saudi Riyal (SAR): Pegged to the USD due to the Petrodollar system.
- Historically, many countries operated under a gold standard where currencies were backed by gold reserves.
- Advantages:
- Provides stability and predictability for trade and investment.
- Prevents excessive inflation if properly maintained.
- Disadvantages:
- Requires large reserves of foreign currency or commodities to maintain the peg.
- Vulnerable to speculative attacks if markets lose confidence in the peg.
- Managed (Dirty Float) Exchange Rates:
- Definition: A hybrid system where currencies are primarily market-driven but subject to intervention by central banks to stabilize or influence exchange rates.
- Examples:
- Chinese Yuan (CNY): Managed through a controlled float within a specified range.
- Indian Rupee (INR): Managed to control volatility but broadly floats.
- Advantages:
- Allows governments to smooth out fluctuations and protect their economies.
- Provides flexibility without full reliance on market forces.
- Disadvantages:
- Frequent interventions can lead to accusations of currency manipulation (e.g., China).
- May distort true market value, leading to trade imbalances.
- Floating Exchange Rates:
10.5 Currency Pairs and Exchange Rates
A currency’s value reflects factors like the size of a country’s economy, growth rate, interest rate levels, inflation, and monetary and fiscal policies. Since these factors vary significantly from country to country, the value of a currency is always expressed relative to another currency.
This relationship is called a currency pair, and it facilitates international trade, investment, and foreign exchange (Forex) trading.
How Currency Pairs Are Constructed
A currency pair is made up of:
- Base Currency (left): The first currency listed.
- Quote Currency (right): The second currency listed.
Example: EUR/USD = 1.25
- Base currency: EUR (Euro)
- Quote currency: USD (U.S. Dollar)
- Meaning: 1 Euro = 1.25 U.S. Dollars
Types of Currency Pairs:
- Majors: Most-traded pairs that include the U.S. Dollar (USD). Examples:
- EUR/USD (Euro/US Dollar)
- GBP/USD (British Pound/US Dollar)
- USD/JPY (US Dollar/Japanese Yen)
- Cross Pairs: Pairs that don’t include the U.S. Dollar. Examples:
- EUR/JPY (Euro/Japanese Yen)
- GBP/CHF (British Pound/Swiss Franc)
- Exotics: Pairs involving a major currency and an emerging market currency. Examples:
- USD/BRL (U.S. Dollar/Brazilian Real)
- EUR/TRY (Euro/Turkish Lira)
- Majors: Most-traded pairs that include the U.S. Dollar (USD). Examples:
Trading Currency Pairs
Currency pairs are traded like stocks or commodities with bid and ask prices:
- Bid Price: What buyers are willing to pay.
- Ask Price: What sellers are asking for.
- Spread: The difference between bid and ask prices—smaller spreads indicate more liquidity.
Example:
- EUR/USD Bid = 1.2498
- EUR/USD Ask = 1.2502
- Spread = 0.0004 (4 pips)
Traders profit by buying low and selling high—or shorting high and covering low—based on movements in the exchange rate.
Factors Influencing Currency Pairs
- Interest Rates: Higher rates attract investment, boosting currency value.
- Economic Growth: Strong economies strengthen currencies.
- Inflation: High inflation weakens a currency’s purchasing power.
- Trade Balances: Surpluses strengthen currencies; deficits weaken them.
- Central Bank Policies: Monetary interventions influence supply and demand.
- Political Stability: Safe-haven currencies (e.g., CHF) appreciate during global uncertainty.
The Forex Market: Scale and Liquidity
The foreign exchange (Forex) market is the largest and most liquid financial market in the world, with a daily trading volume of $7.5 trillion (2022).
- Market Hours: Open 24 hours a day, 5 days a week across global trading hubs (London, New York, Tokyo).
- Leverage: Traders can use borrowed funds to control larger positions, increasing both potential gains and risks.
10.6 Purchasing Power Parity (PPP)
Purchasing Power Parity (PPP) is an economic theory used to compare the relative value of currencies by measuring how much a standard set of goods and services (a “basket of goods”) costs in different countries. It adjusts for inflation and cost-of-living differences to determine whether currencies are overvalued or undervalued compared to one another.
How Does PPP Work?
The idea behind PPP is that, in an ideal world with no transportation costs or trade barriers, identical goods should cost the same in any two countries when measured in a common currency.
For example:
- A hamburger should cost the same in the U.S. and Japan after converting the price into the same currency.
- If it costs $5 in the U.S. and ¥750 in Japan, and the exchange rate is 1 USD = 150 JPY, PPP suggests the currencies are fairly valued (because 750/150 = 5).
- However, if the exchange rate were 1 USD = 100 JPY, then the yen would be overvalued (since ¥750 would equal $7.50, making Japanese burgers more expensive).
Why is PPP Important?
- Economic Comparison:
- It allows economists to compare standards of living between countries by adjusting for price differences.
- Example: $10 might buy more goods in India than in Switzerland, meaning India has a lower cost of living.
- Currency Valuation:
- PPP helps identify whether a currency is undervalued or overvalued relative to another.
- Undervalued currencies make exports cheaper and imports more expensive, influencing trade and economic growth.
- Exchange Rate Adjustment:
- It predicts long-term exchange rate movements, as currencies tend to adjust toward PPP over time.
- Economic Comparison:
The Big Mac Index: A PPP Example
The Big Mac Index, created by The Economist, is a fun and practical way to illustrate PPP. It compares the cost of a McDonald’s Big Mac in various countries, since the burger is a globally standardized product.
Example (2023):
- U.S.: A Big Mac costs $5.50.
- Switzerland: A Big Mac costs CHF 6.50.
- Using the exchange rate 1 USD = 0.90 CHF, the Swiss Big Mac costs $7.22 (6.50 ÷ 0.90).
- Since $7.22 is more than $5.50, the Swiss franc appears overvalued relative to the U.S. dollar.
Real-World Use:
- If a currency is undervalued, it may boost exports by making goods cheaper for foreign buyers.
- If a currency is overvalued, it can hurt exports and create trade deficits because goods become more expensive internationally.
Limitations of PPP:
While PPP is useful, it has some limitations:
- Different Goods and Services:
- Not all goods are traded internationally (e.g., real estate, utilities). These local prices vary significantly.
- Market Distortions:
- Taxes, tariffs, and regulations affect prices and deviate from theoretical parity.
- Economic Differences:
- Wealthier nations often have higher wages and costs of living, skewing comparisons.
- Different Goods and Services:
Key Takeaway:
Purchasing Power Parity (PPP) is a tool for comparing currencies based on what they can buy in their respective countries. Real-world indices, like the Big Mac Index, provide simple insights into currency valuations, trade competitiveness, and economic conditions.
10.7 U.S. Dollar Index (USDX) and Currency Valuation
The U.S. Dollar Index (USDX) measures the dollar’s strength relative to a basket of six major currencies—the Euro, Yen, Pound Sterling, Canadian Dollar, Swedish Krona, and Swiss Franc.
- Established in 1973, it serves as a benchmark for dollar strength.
- Movements in the index affect international trade, commodity prices, and debt costs.

10.9 Currency Wars: Competitive Devaluation
Nations sometimes engage in competitive devaluation—intentionally lowering the value of their currency to make exports cheaper and imports more expensive. This strategy is often used to boost domestic manufacturing, increase exports, and stimulate economic growth. However, it can also trigger currency wars, where countries retaliate with their own devaluations, leading to global economic instability.
Example: Japan and the Yen—Toyota’s Competitive Edge
Background:
Japan has historically relied on export-driven growth, particularly in industries like automotive manufacturing and electronics. Companies like Toyota depend heavily on foreign sales, particularly in the United States.
Monetary Policy:
The Bank of Japan (BoJ) has employed expansionary monetary policies—including quantitative easing (QE) and ultra-low interest rates—to weaken the yen (¥) and maintain competitiveness.
Currency Impact:
- In 2022, the USD/JPY exchange rate moved from around 115 to 150 yen per dollar, a 30% depreciation of the yen.
- This made Japanese exports cheaper for U.S. consumers, boosting sales of products like Toyota cars, which became more affordable compared to American or European alternatives.
Example Calculation—Toyota Tacoma:
- Assume the price of a Toyota Tacoma in Japan is 4,800,000 yen.
- At an exchange rate of 1 USD = 115 JPY, the price in dollars is:
4,800,000 ÷ 115 = $41,739 - After the yen weakens to 1 USD = 150 JPY, the price drops to:
4,800,000 ÷ 150 = $32,000
Result:
- U.S. consumers now find Japanese cars cheaper, boosting demand for Toyota and other Japanese exports.
- Japanese manufacturers gain a competitive advantage, increasing production and profits.
Consequences of Competitive Devaluation
Short-Term Benefits:
- Exports increase due to cheaper prices abroad.
- Domestic employment rises in export-focused industries.
- Economic growth accelerates, at least temporarily.
Long-Term Risks:
- Imported goods become more expensive, leading to inflation.
- Consumer purchasing power declines, particularly for imported essentials like food and energy.
- Other countries may retaliate by devaluing their own currencies, triggering a currency war that destabilizes global trade.
Historical Context:
- In the 1930s, competitive devaluations among nations deepened the Great Depression as global trade collapsed.
- More recently, China has faced accusations of currency manipulation to keep its yuan (CNY) artificially low and boost exports.
- Japan’s policies in the 2010s under Abenomics similarly drew criticism for potentially igniting a currency war.
Key Takeaway:
Competitive devaluation is a double-edged sword. While it may temporarily boost exports and economic growth, it risks igniting broader economic conflicts that can destabilize global markets, leading to trade wars or even recessions.
10.10 Global Debt: A World Addicted to Borrowing
Overview of Global Debt
Global debt has reached unprecedented levels, fueled by fiat currency systems, deficit spending, and cheap credit policies implemented by central banks. According to the International Monetary Fund (IMF) and the Institute of International Finance (IIF):
- Total global debt surpassed $307 trillion as of Q3 2023—equal to approximately 335% of global GDP.
- Governments, corporations, and households are all contributors, but sovereign debt accounts for the largest share.
Breakdown by Sector
- Government Debt:
- Accounts for nearly 40% of total global debt.
- Fueled by deficit spending, wars, social programs, and stimulus measures.
- Example: The U.S. national debt exceeds $33 trillion, with annual interest payments surpassing $1 trillion.
- Corporate Debt:
- Businesses rely on debt financing to fund operations, growth, and mergers.
- Rising interest rates have increased borrowing costs, leading to concerns about defaults and bankruptcies.
- Household Debt:
- Mortgages, auto loans, student loans, and credit cards contribute to consumer debt levels.
- Government Debt:
In developed economies, household debt as a percentage of income is particularly high (e.g., U.S., Canada, and Australia).
Global Debt by Country (Top Debtors)
- United States:
- Total debt: Over $33 trillion (Government).
- Debt-to-GDP ratio: 125%.
- Monetary Policy: Expansionary—low interest rates and quantitative easing (now reversing).
- Japan:
- Total debt: ¥1.28 quadrillion yen (~$9 trillion USD).
- Debt-to-GDP ratio: Over 260% (highest globally).
- Monetary Policy: Ultra-low interest rates and government bond purchases.
- China:
- Total debt: $14 trillion USD (Government) + significant corporate and municipal debt.
- Debt-to-GDP ratio: 280% (including corporate debt).
- Monetary Policy: State-controlled credit expansion and capital controls.
- European Union (EU):
- Collective debt: €13 trillion (~$14 trillion USD).
- Debt-to-GDP ratio: Varies by country; Greece (177%), Italy (144%), France (112%).
- Monetary Policy: Managed by the European Central Bank (ECB)—quantitative easing and negative interest rates.
- Emerging Markets (Brazil, India, South Africa):
- High debt burdens but often denominated in foreign currencies (e.g., USD), making them vulnerable to exchange rate volatility and debt crises.
Consequences of Rising Debt Levels
- Economic Instability:
- High debt burdens increase the risk of financial crises when borrowing costs rise.
- Example: Eurozone Debt Crisis (2010-2012), where Greece required multiple bailouts to avoid default.
- Interest Payments:
- Rising debt leads to higher interest payments, diverting resources from infrastructure, education, and healthcare.
- Example: The U.S. spends more on interest payments than on national defense.
- Currency Devaluation and Inflation:
- Governments may print money to pay off debts, leading to inflation and devaluation.
- Example: Venezuela and Zimbabwe’s hyperinflation crises.
- Wealth Inequality:
- Debt-driven asset inflation often benefits wealthier individuals who own stocks and real estate, widening the wealth gap.
- Sovereign Debt Defaults:
- Countries unable to service their debts may default, leading to economic collapse and social unrest.
- Example: Argentina (2001) and Sri Lanka (2022).
10.11 Debt and Fiat Currency—An Unstable Marriage
Fiat currencies and debt are inherently linked because fiat systems enable governments to borrow without constraints, often resulting in deficit spending and money printing to cover shortfalls.
- Debt Dependency: Fiat systems encourage reliance on borrowing rather than taxation or economic productivity to fund spending.
- Debt-to-GDP Ratios: Economists warn that debt-to-GDP ratios above 90% slow growth and lead to economic stagnation.
- Inflationary Pressures: When debt grows too large, central banks often monetize it, leading to currency devaluation and inflation.
Key Takeaways
- Global Debt Crisis: With debt levels surpassing 300% of global GDP, the world’s reliance on fiat currency systems is increasingly unstable.
- Economic Risks: Rising debt amplifies risks of financial crises, inflation, and sovereign defaults, especially in emerging markets.
- The Role of Fiat Currency: Fiat systems, lacking commodity backing, have made borrowing too easy, leading to unsustainable economic practices.
- Future Questions: Will nations reform their monetary systems, embrace commodity-backed alternatives, or double down on digital fiat currencies (CBDCs) to maintain control?
10.12 Currency Crises, Hyperinflation, and Debt Dependency
Examples of currency collapses highlight the vulnerabilities of fiat currency systems. Mismanagement, excessive debt, and loss of confidence often lead to inflation spirals, eroded savings, and economic hardship.
Historical and Recent Cases of Currency Collapse:
Weimar Germany (1923)
- Cause: Reparations from World War I and money printing to cover debts.
- Impact: Hyperinflation wiped out savings and pensions.
- Key Statistic: Prices doubled every 4 days, and workers were paid twice daily to buy goods before prices increased.
Zimbabwe (2008)
- Cause: Land reforms, collapse of agricultural exports, and excessive money printing.
- Impact: Inflation hit 89.7 sextillion percent annually, forcing Zimbabwe to abandon its currency.
- Outcome: The U.S. dollar became the de facto currency until Zimbabwe reintroduced its currency in 2019.
Venezuela (2016–2021)
- Cause: Falling oil prices, government overspending, and reliance on imports.
- Impact: Inflation surpassed 1,000,000%, leading to severe poverty and mass emigration.
- Current Status: The Bolívar was redenominated multiple times and replaced by the Petro, a cryptocurrency, but instability persists.
Argentina (1980s, 2001, and 2023)
- Cause (1980s): Military dictatorship overspending and borrowing led to defaults.
- Cause (2001): Currency peg to the U.S. dollar collapsed, leading to banking freezes and riots.
- Cause (2023): Persistent fiscal deficits, excessive debt, and reliance on printing money.
- Impact: Inflation exceeded 140% in 2023, with the Argentine Peso (ARS) rapidly losing value.
- Current Status: Argentina faces debt dependency and inflation-driven poverty. The blue dollar market (parallel exchange rate) reflects a lack of trust in the official peso.
Turkey (2018–2023)
- Cause: Unorthodox monetary policies and government interference in central banking.
- Impact: Inflation soared above 85% in 2022, severely impacting wages and savings.
- Currency Status: The Turkish Lira (TRY) lost more than 400% of its value against the U.S. dollar since 2018.
- Key Policies: Rate cuts during inflation caused distrust in monetary management.
Lebanon (2019–Present)
- Cause: Government corruption, debt defaults, and mismanagement of public funds.
- Impact: The Lebanese Pound (LBP) lost 98% of its value, wiping out savings.
- Key Statistic: Inflation exceeded 200% annually as the financial sector collapsed.
- Current Status: Lebanon faces economic depression, poverty, and food insecurity.
Greece (2009–2015)
- Cause: Excessive borrowing and structural weaknesses in the Eurozone.
- Impact: Greece’s debt crisis triggered austerity measures, bailouts, and public unrest.
- Key Statistic: Debt-to-GDP exceeded 180%, leading to multiple IMF interventions.
- Recovery Efforts: Greece remained in recession for nearly a decade and still faces economic challenges.
Brazil (1980s–1994)
- Cause: External debt crises and political instability.
- Impact: Hyperinflation peaked at 2,477% in 1993.
- Key Statistic: Brazil implemented six different currencies between 1986 and 1994 before stabilizing the Real (R$).
- Current Status: Brazil has maintained stability but remains vulnerable to inflationary pressures.
Key Lessons from Currency Collapses:
- Excessive Debt: Heavy borrowing often leads to default and currency devaluation.
- Lack of Trust: Fiat currencies depend entirely on public confidence and fiscal discipline.
- Hyperinflation: Unchecked money printing quickly erodes savings and purchasing power.
- Dollarization: Countries facing collapse often turn to foreign currencies (like the U.S. dollar) for stability.
- Emerging Alternatives: Cryptocurrencies and commodity-backed systems may gain traction as fiat currencies falter.
10.13 Dollar Hegemony: The Power of the U.S. Dollar
The U.S. dollar holds a dominant position in the global economy as the world’s reserve currency. This dominance, often referred to as dollar hegemony, stems from the Bretton Woods Agreement (1944), which established the dollar as the backbone of international trade and finance. Even after the gold standard ended in 1971, the dollar’s role was reinforced by the Petrodollar system, requiring oil to be priced and traded in U.S. dollars.
Key Features of Dollar Hegemony:
- Global Reserve Currency: Central banks and governments hold U.S. dollars as reserves to stabilize their economies and conduct international trade.
- Trade and Finance Dominance: Most commodities, including oil, are priced in dollars, making it the default currency for global transactions.
- U.S. Economic Leverage: The U.S. can impose sanctions, influence markets, and finance deficits more easily because of global reliance on the dollar.
Pros of Dollar Hegemony:
- Liquidity and Stability: Ensures widespread trust and usage in global trade.
- Financing Advantages: Enables the U.S. to borrow cheaply and run trade deficits without immediate consequences.
- Global Influence: Provides geopolitical leverage through sanctions and financial regulations.
Cons of Dollar Hegemony:
- Dependency Risks: Other countries must accumulate and hold U.S. debt to maintain reserves, making them vulnerable to U.S. monetary policy.
- Trade Imbalances: Dollar strength often leads to persistent trade deficits for the U.S.
- Economic Inequality: Expansionary U.S. monetary policies can lead to inflation and inequality both domestically and globally.
Challenges to Dollar Hegemony:
- Rising Debt Levels: The U.S. national debt raises concerns about long-term sustainability.
- Geopolitical Rivals: Nations like China and alliances such as BRICS are pushing for alternatives to reduce reliance on the dollar.
- Cryptocurrencies and CBDCs: Decentralized systems like Bitcoin and state-backed digital currencies may challenge the dollar’s dominance.
The Future of Dollar Hegemony:
While the U.S. dollar remains the world’s dominant currency, challenges from emerging economies, digital currencies, and growing debt suggest a more multipolar financial system could emerge in the future. Whether this transition strengthens or undermines global stability remains an open question.
Key Takeaway:
Dollar hegemony allows the United States to create U.S. dollars—fiat currency with no intrinsic value—essentially out of thin air. With this “magic money,” Americans purchase real, tangible products that other nations produce—goods that require labor and resources. This imbalance forms the foundation of the current global economic system, enabling the U.S. to sustain trade deficits while maintaining economic dominance.
Conclusion:
Fiat currency has shaped the global economy, enabling trade, growth, and liquidity. However, it also faces mounting challenges, including debt crises, inflation, and digital disruption. The dominance of the U.S. dollar as the world’s reserve currency has provided stability but also created economic imbalances and dependency risks for other nations. As trust in fiat monetary systems erodes, the financial world may move toward Central Bank Digital Currencies (CBDCs), cryptocurrencies, or even a return to a commodity-backed monetary system—potentially shifting toward a more multipolar monetary order.
