c - Exchange Rate Misalignment

Exchange Rate Misalignment

Overview

Under floating exchange rates, exchange rates do not always adjust quickly enough to maintain external balance.

Financial markets may keep exchange rates at levels that generate persistent current account deficits or surpluses for many years.

These prolonged departures from the exchange rate consistent with external balance are known as exchange rate misalignments.

Definition

An exchange rate misalignment is a persistent deviation of the real exchange rate from the level consistent with external balance.

As a result,

a country experiences prolonged current account deficits or surpluses that are not immediately corrected by exchange rate movements.

Historical Context

Before the collapse of the Bretton Woods system, many economists argued that floating exchange rates would automatically eliminate persistent external imbalances.

Experience after 1973 showed that this prediction was only partially correct.

Although exchange rates became more flexible,

large current account imbalances continued to persist for many years.

Examples include:

• the large U.S. current account deficits of the 1980s;
• Japan's persistent current account surpluses;
• the global imbalances of the 2000s. :contentReference[oaicite:1]{index=1}

How Misalignment Occurs

Under floating exchange rates,

exchange rates are determined in financial markets.

These markets respond not only to trade flows but also to:

• capital movements;
• expectations;
• risk premia;
• portfolio decisions.

As a consequence,

the exchange rate may remain above or below its long-run equilibrium value for extended periods.

Consequences for External Balance

When the exchange rate remains misaligned,

external imbalances persist.

An overvalued currency tends to produce:

• weaker exports;
• stronger imports;
• current account deficits.

An undervalued currency tends to produce:

• stronger exports;
• weaker imports;
• current account surpluses.

Adjustment may occur only gradually.

Why Doesn't the Market Correct Immediately?

Financial markets react to many factors besides trade.

Examples include:

• changes in investor expectations;
• capital inflows and outflows;
• shifts in risk perceptions;
• monetary policy differences.

These forces can dominate trade adjustment for long periods,

delaying the return toward external balance.

Political Consequences

Persistent exchange rate misalignments often generate political tensions.

Domestic producers facing stronger foreign competition may demand:

• import protection;
• trade restrictions;
• exchange rate intervention.

As a result,

misalignments frequently increase political pressure for protectionist policies.

Economic Intuition

Floating exchange rates improve the flexibility of the international monetary system,

but they do not guarantee continuous external balance.

Exchange rates can remain "too high" or "too low" relative to economic fundamentals,

allowing external imbalances to persist much longer than originally expected.

Advantages

• Flexible exchange rates eventually facilitate adjustment.
• Financial markets continuously incorporate new information.
• No formal parity changes are required.

Limitations

• External adjustment may be very slow.
• Large current account imbalances can persist.
• Exchange rates may overshoot or remain misaligned.
• Political pressures for protectionism may increase.

• Why do exchange rate misalignments generate political pressure?

Common Misconceptions

"Floating exchange rates always restore external balance quickly."

False.

Experience since 1973 shows that large current account imbalances can persist for many years despite floating exchange rates. :contentReference[oaicite:2]{index=2}

"A misaligned exchange rate is necessarily the result of government intervention."

False.

Misalignments may arise naturally from private financial market behavior, expectations, and capital flows.

"Misalignment means the exchange rate is fixed."

False.

Misalignment can occur under both fixed and floating exchange rate regimes.

Under floating rates,

it reflects the fact that market-determined exchange rates do not always coincide with the level consistent with external balance.

Key Takeaways

• Exchange rate misalignment is a persistent deviation from the exchange rate consistent with external balance.
• Floating exchange rates do not automatically eliminate external imbalances.
• Capital flows and financial market expectations can delay adjustment.
• Misalignments contribute to prolonged current account deficits or surpluses.
• Persistent misalignments often generate political pressure for protectionist measures.
