Devisenabwertung

What Is Devisenabwertung?

Devisenabwertung, or currency devaluation, is a deliberate downward adjustment of a country's official Wechselkurs relative to other currencies. This policy decision, typically made by a government or its Zentralbank within the realm of Währungspolitik, aims to make a nation's exports cheaper and imports more expensive. Unlike depreciation, which is driven by market forces, devaluing a currency is an intentional act to address specific economic objectives, often related to trade balances or foreign debt. A country might resort to Devisenabwertung to boost its export competitiveness or to reduce a persistent current account deficit.

History and Origin

Throughout economic history, governments have occasionally intervened in currency markets to achieve policy goals. A notable period for currency devaluations was under the Bretton Woods system, established after World War II, which pegged many currencies to the U.S. dollar, which in turn was convertible to gold. Under this system, countries could adjust their pegged exchange rates in cases of "fundamental disequilibrium" with the agreement of the International Monetary Fund (IMF). The collapse of Bretton Woods in the early 1970s led to more flexible exchange rate regimes, but countries continued to use devaluation as a policy tool, especially in times of economic distress.,

A prominent example of widespread devaluations occurred during the 1997 Asian Financial Crisis. Several Southeast Asian economies, including Thailand, Indonesia, and South Korea, faced immense pressure on their currencies due to large capital outflows and speculative attacks. Thailand's decision to devalue the baht in July 1997, after depleting much of its foreign exchange reserves, is often cited as the trigger for the broader regional crisis that saw other currencies, like the Indonesian rupiah and the Korean won, also devalued significantly.,⁴ This period highlighted the interconnectedness of global financial markets and the rapid contagion that can follow a major currency adjustment.

Key Takeaways

• Devisenabwertung is a deliberate government or central bank policy to lower a currency's fixed exchange rate.
• It aims to make exports cheaper and imports more expensive, potentially boosting a nation's trade balance.
• Currency devaluation can increase the cost of foreign debt denominated in other currencies and may lead to domestic Inflation.
• It is often employed as a last resort to correct large economic imbalances or to stimulate a struggling economy.
• The effects of Devisenabwertung are complex and can have both positive and negative consequences for different sectors of an economy.

Formula and Calculation

Devisenabwertung itself is a policy decision rather than a calculation. However, its magnitude can be expressed as a percentage change in the exchange rate. If a currency's value changes from an initial exchange rate (E_0) to a new, devalued exchange rate (E_1) (where (E) is expressed as units of foreign currency per unit of domestic currency), the percentage devaluation can be calculated as:

Alternatively, if the exchange rate is quoted as units of domestic currency per unit of foreign currency (e.g., USD/EUR, where USD is domestic), then a devaluation means it takes more domestic currency to buy one unit of foreign currency. In this case, if (E_0) is the initial rate and (E_1) is the new, higher rate:

Where:

• (E_0) = Initial Wechselkurs
• (E_1) = New, devalued exchange rate

This formula helps quantify the extent of the currency's value reduction on the Devisenmarkt.

Interpreting Devisenabwertung

The interpretation of Devisenabwertung hinges on its intended effects and the broader economic context. When a country devalues its currency, it effectively lowers the price of its goods and services for foreign buyers, making its Exporte more competitive internationally. Concurrently, foreign goods become more expensive for domestic consumers, reducing Importe. This can help improve a country's Handelsbilanz and overall Zahlungsbilanz.

However, the interpretation is not always straightforward. A significant devaluation can signal economic weakness or instability, potentially deterring Auslandsinvestitionen and increasing the cost of servicing foreign-denominated debt. While it might stimulate export-oriented industries, import-reliant sectors or consumers purchasing foreign goods will face higher costs. The success of a Devisenabwertung depends on various factors, including the elasticity of demand for exports and imports, the presence of wage and price rigidities, and the reactions of trading partners.

Hypothetical Example

Consider a hypothetical country, "Econland," whose currency, the "Econ," is pegged to the U.S. dollar at a rate of 1 USD = 5 Econ. Econland has been experiencing a persistent trade deficit, as its exports are deemed too expensive on the global market, and its citizens are importing a large volume of foreign goods.

To address this imbalance and boost its struggling export industries, Econland's central bank decides to devalue the Econ. They announce a new official exchange rate of 1 USD = 6 Econ.

Before devaluation:

• An Econland exporter sells goods worth 1 USD, receiving 5 Econ.
• An Econland consumer buys goods worth 1 USD, paying 5 Econ.

After devaluation:

• The same Econland exporter sells goods worth 1 USD, now receiving 6 Econ. This means their products are effectively cheaper for foreign buyers, making them more competitive.
• The Econland consumer buying goods worth 1 USD must now pay 6 Econ. This makes imported goods more expensive, discouraging their purchase and encouraging domestic consumption.

This intentional adjustment aims to stimulate Econland's export growth and curb its reliance on imports, ultimately impacting its Handelsbilanz.

Practical Applications

Devisenabwertung is a tool of Währungspolitik that governments may employ in specific economic scenarios. One primary application is to enhance export competitiveness. By making domestic goods cheaper for foreign buyers, a country hopes to increase its export volumes and gain a larger share of global markets. This can be particularly appealing to economies with significant export sectors or those facing a downturn.

Another application involves correcting a large and sustained current account deficit. If a country is consistently importing more than it exports, a devaluation can help rebalance trade flows by making imports more costly and exports more attractive. This can help stabilize the nation's Zahlungsbilanz.

However, the impact on the economy is multifaceted. While a weaker currency can benefit exporters, it also means that Importe become more expensive, which can lead to higher domestic prices (imported Inflation). For example, a strong U.S. dollar, which is the opposite of a devaluation of other currencies against the dollar, generally benefits American consumers by making imports cheaper, but it can harm U.S. exporters by making their goods more expensive abroad. The reverse would be true for a dollar devaluation. T²he Federal Reserve Bank of San Francisco, as part of the U.S. central bank, monitors exchange rate movements as they influence economic growth and inflation.

Furthermore, devaluing a currency can increase the local currency cost of servicing foreign-denominated debt, a critical consideration for countries with substantial external borrowings. This was a significant factor during the 1997 Asian Financial Crisis, where many Asian economies held substantial foreign debt.

Limitations and Criticisms

Despite its potential benefits, Devisenabwertung comes with several limitations and criticisms. A primary concern is the risk of imported Inflation. As imports become more expensive, the cost of raw materials and finished goods that a country relies on from abroad increases, which can feed into domestic prices and reduce the purchasing power of citizens.

Another major drawback is the increased burden of foreign debt. For countries with significant amounts of debt denominated in foreign currencies, a devaluation means it takes more local currency to repay the same amount of foreign currency principal and interest. This can lead to a debt crisis if the country's finances are already strained. The International Monetary Fund (IMF) often gets involved in such situations, providing financial assistance conditioned on policy reforms, including exchange rate adjustments.

Furthermore, Devisenabwertung can erode public and investor confidence, potentially leading to capital flight and deterring future Auslandsinvestitionen. It might also provoke retaliatory devaluations from trading partners, leading to a "currency war" where multiple countries try to gain an export advantage, ultimately harming global trade. The IMF highlights that while devaluation can be a valuable policy tool in response to large economic shocks, the choice of an exchange rate system involves trade-offs and impacts the entire economy in terms of price incentives. E¹xcessive Spekulation can also exacerbate the volatility of currencies during periods of perceived instability or policy shifts, increasing Währungsrisiko.

Devisenabwertung vs. Abwertung

While often used interchangeably in everyday language, "Devisenabwertung" and "Abwertung" refer to distinct processes in the realm of currency movements. The key difference lies in the mechanism driving the change.

Devisenabwertung is an intentional, official policy decision made by a government or its central bank. It occurs in a fixed or managed exchange rate system where the authorities explicitly reduce the official value of their currency against another currency or a basket of currencies. This is a deliberate act of Geldpolitik aimed at achieving specific economic goals, such as boosting exports or reducing a trade deficit. The country still maintains a degree of control over its Wechselkurs.

Abwertung, or currency depreciation, is a market-driven phenomenon. It occurs in a floating exchange rate system where the value of a currency falls due to the forces of supply and demand on the Devisenmarkt. Factors such as economic performance, interest rate differentials, inflation rates, political stability, and market Spekulation can cause a currency to depreciate without any direct government intervention. In this system, the market determines the currency's value.

In essence, devaluation is an act of policy, while depreciation is a market outcome. Both result in a weaker domestic currency relative to foreign currencies, but their causes and the implications for policy control differ significantly.

FAQs

What causes a country to devalue its currency?

A country typically devalues its currency to make its Exporte cheaper and more competitive in global markets, thereby boosting economic growth and improving its Handelsbilanz. It might also be done to reduce a current account deficit or to make imports more expensive to curb domestic demand for foreign goods.

What are the main benefits of currency devaluation?

The primary benefits of Devisenabwertung include increased export competitiveness, a potential reduction in trade deficits, and a boost to domestic industries that compete with imports. It can also help stimulate economic activity by making local goods more attractive.

What are the risks associated with Devisenabwertung?

Key risks include higher domestic Inflation due to more expensive imports, an increased burden on foreign-denominated debt, and a potential loss of investor confidence. It could also lead to retaliatory measures from other countries, diminishing the intended benefits.

How does devaluation affect consumers?

For consumers, Devisenabwertung generally means that imported goods and services become more expensive. This can lead to a decrease in their purchasing power, especially if a significant portion of their consumption relies on imports. Travel abroad also becomes more costly.

Is Devisenabwertung always effective?

No, the effectiveness of Devisenabwertung depends on various factors. If the demand for a country's exports and imports is not sensitive to price changes (inelastic), or if other countries respond with their own devaluations, the desired economic benefits may not materialize or could be short-lived. The overall economic stability and the level of a country's Währungsreserven also play a role.
