International Finance and Monetary Systems

International Finance and Monetary Systems

International finance is a field where politics and economics are intertwined especially closely. Monetary systems, capital flows, financial crises — all these are shaped by the interaction of market forces and political decisions.

“The Impossible Trinity”

A central concept in international finance is the trilemma (impossible trinity):

Three goals:

• Fixed exchange rate — predictability for trade
• Free movement of capital — efficient allocation of investments
• Independent monetary policy — ability to respond to domestic conditions

Impossibility. It is possible to achieve any two, but not all three at the same time. If the exchange rate is fixed and capital is free, interest rates are determined externally (capital outflow if rates are lowered). If you want an independent policy, you must let the rate float or restrict capital flows.

Choice of regime. Different countries make different choices:

• USA — floating exchange rate and free movement of capital, independent policy.
• Hong Kong — currency board, free capital, no independent policy.
• China (historically) — capital controls, managed exchange rate, independent policy.

Evolution of Monetary Systems

Gold Standard (1870–1914). Fixed rates via linkage to gold. Automatic adjustment mechanism (Hume). Limited policy autonomy. Deflationary bias.

Interwar chaos. Attempts to restore the gold standard failed. Devaluations, competitive depreciations, capital controls.

Bretton Woods (1944–1971). Fixed but adjustable exchange rates. Dollar pegged to gold, others pegged to dollar. IMF supports countries with balance-of-payments problems. Capital controls were permitted.

Collapse of Bretton Woods (1971). The US cannot maintain dollar convertibility to gold. Nixon closes the “gold window”. Transition to floating exchange rates.

Modern “non-system”. A diversity of regimes: floating exchange rates of major currencies, various forms of pegs, managed floating. The dollar remains the dominant currency.

Financial Globalization

Since the 1980s — massive liberalization of capital movements:

Arguments “for”:

• Efficient global allocation of capital
• Consumption smoothing via borrowing
• Discipline for macroeconomic policy
• Transmission of technology and managerial practices

Arguments “against”:

• Volatility and sudden stops
• Financial crises
• Loss of political autonomy
• Overheating and bubbles

Empirics. The link between financial openness and growth is ambiguous. Benefits for countries with good institutions, risks for others.

Financial Crises

Financial globalization is accompanied by crises:

Anatomy of crises:

• Capital inflow → credit boom → bubbles
• Shock or change of sentiment → outflow
• Devaluation and/or banking crisis
• Recession, rising unemployment, political instability

Examples:

• Mexico 1994 — “tequila crisis”
• Asian crisis 1997–1998 — Thailand, Indonesia, Korea
• Russia 1998 — default and devaluation
• Argentina 2001 — collapse of currency board
• Global financial crisis 2008 — epicenter in the USA, global spread

Role of the IMF. The IMF is a “lender of last resort” for countries. Loan conditions (conditionality) — structural reforms. Criticism: conditions are too strict, procyclical, impose the neoliberal model.

Regulation after 2008

The global crisis of 2008 changed approaches:

• Banking regulation (Basel III).
• Increased requirements for bank capital and liquidity.
• Macroprudential supervision.
• Rehabilitation of capital controls.

The IMF recognized the legitimacy of inflow restrictions under certain conditions. Capital flow management measures — new terminology.

Global financial safety net.

• Expansion of IMF resources,
• Regional mechanisms (Chiang Mai Initiative in Asia),
• Bilateral central bank swap lines.

Incomplete reforms.

• “Too big to fail” is unresolved.
• Coordination between jurisdictions insufficient.
• Shadow banking is growing.

The Dollar and the International Monetary System

The dollar remains the center of the system:

• “Excessive privilege.” The USA can borrow in its own currency.
• Demand for dollars as reserves lowers financing costs.
• Global financial cycle. Fed policy affects the entire world. When the Fed tightens — capital outflow from emerging markets.

Challenges to dollar hegemony:

• The euro — did not become a competitor (eurozone crisis)
• The yuan — limited by capital controls
• Cryptocurrencies, central bank digital currencies — still marginal

Dollarization of sanctions. The USA uses control over the dollar system for sanctions. This stimulates the search for alternatives.
