Currency Devaluation: What is it and How Does it Work?

Currency devaluation refers to the deliberate reduction in the value of a country's currency relative to other currencies. This economic policy is often used by governments to address trade imbalances, boost exports, or manage economic crises. When a currency is devalued, it becomes cheaper for foreign buyers, making the country's goods and services more attractive on the global market.

However, devaluation also has its downsides, such as making imports more expensive and potentially increasing inflation domestically. In this article, we will explore the mechanics of currency devaluation, the reasons why governments opt for this strategy, and its broader impact on the economy.

What is Currency Devaluation?

Currency devaluation is the deliberate reduction of the value of a country's currency relative to another currency or a basket of currencies. It is different from currency depreciation, which is the natural fluctuation of the exchange rate due to market forces. Currency devaluation is usually a policy decision made by a country's government or central bank to achieve particular economic objectives.

In 1994, Mexico encountered a financial crisis, leading to a 15% devaluation of its currency, the peso, against the U.S. dollar. This devaluation spurred a considerable capital outflow, triggered by investor fears of additional depreciation and defaulting debts. The crisis echoed in other emerging markets, like Argentina and Brazil, posing a risk to global financial stability. The U.S. and the International Monetary Fund (IMF) acted promptly, extending a $50 billion bailout package to Mexico. This intervention played a crucial role in reviving confidence and stabilizing the peso.

How Currency Devaluation Works

Currency devaluation is the deliberate lowering of a country's currency value compared to another's, affecting the exchange rate. It modifies the economy by changing import and export dynamics, potentially stimulating economic growth, but it also can spur inflation.

For instance, if a country devalues its currency by 10%, its money buys 10% less of another. This change impacts imports and exports — imports become pricier and exports cheaper. Consequently, demand for domestic products may rise as they become more globally competitive, while demand for foreign goods could drop from the increased domestic cost.

This shift can enhance the country's trade balance — the difference between exports and imports — and potentially stimulate economic growth and employment. Yet, it can also inflate costs as import prices increase and production costs for domestic producers rise.

Devaluation can also affect a country's international trade competitiveness. Making products more affordable for foreign buyers could boost market share and export revenues. However, if other countries respond with devaluation or trade barriers, it could result in a currency war, damaging trust, reducing trade volumes and negatively impacting all involved parties.

Currency devaluation also has implications for tourism and foreign investment. A cheaper currency can attract more tourists and foreign direct investment as travel and business establishment costs drop. Conversely, it might deter residents from overseas trips and foreign portfolio investors from financial asset trading.

Causes of Currency Devaluation

Currency devaluation is not a random or spontaneous event. It is usually caused by economic factors or policy decisions that affect the supply and demand of a currency in the foreign exchange market. 

Government and Central Bank Policies Affecting Currency Devaluation

Some of the government and central bank policies that can affect currency devaluation are:

• Intervention in foreign exchange markets: This action involves a government or central bank manipulating currency values by buying or selling currencies. If the aim is devaluation, the entity can sell its currency and purchase another in vast amounts, increasing its own currency's supply while diminishing the other's. This action typically lowers the currency's exchange rate, resulting in devaluation.
• Monetary policy adjustments: Monetary policy comprises strategies a central bank uses to regulate money supply and interest rates. A central bank might adopt an expansionary monetary policy to devalue its currency, increasing the money supply and reducing interest rates. Although it can boost economic activity and inflation, it can also make the currency less attractive to savers and investors, lowering its exchange rate and potentially leading to devaluation.
• Fiscal policy decisions: Fiscal policy involves government regulation of spending and taxation. A government might employ an expansionary fiscal policy to force currency devaluation, increasing spending and reducing taxes. Although doing so could stimulate economic activity and inflation, it might also escalate fiscal deficit and public debt. Consequently, it could undermine the currency's credibility among foreign investors, decreasing its demand and potentially leading to devaluation.

Implications of Currency Devaluation

Currency devaluation can have positive and negative consequences for a country and its trading partners, depending on various factors such as the magnitude, frequency, timing, motivation, coordination and response.

Positive Consequences of Currency Devaluation

Some of the positive consequences of currency devaluation are:

• Higher export competitiveness: Currency devaluation can make a country's exports cheaper and more attractive in terms of foreign currencies, increasing demand for its products in the global market. This action can improve its trade balance, export revenues, market share, economic growth, employment and income levels.
• Increased foreign direct investment: Currency devaluation can also make a country's assets cheaper and more attractive in terms of foreign currencies, which can increase the inflow of foreign direct investment into the country. Foreign direct investment can bring benefits such as capital, technology, skills, jobs and market access to the host country, enhancing its productivity and competitiveness.
• It can reduce external debt burden: When a country's currency is devalued, it can decrease the actual value of its external debt, which is the money owed to foreign creditors. This can alleviate the strain on the country's balance of payments, which tracks all financial dealings between a government and the rest of the world, enhancing its credit rating and improving borrowing conditions in the global financial market.

Negative Consequences of Currency Devaluation

Some of the negative consequences of currency devaluation are:

• Higher import prices: Currency devaluation can raise import prices, making foreign goods costlier domestically and potentially limiting their supply and availability. This shift could alter a country's consumption and production habits, impacting the standard of living and overall welfare.
• Inflationary pressures: It can elevate a country's general price level of goods and services as import prices surge and domestic production costs increase. This scenario can diminish citizens' purchasing power and real income, generating economic uncertainty. Consequently, central banks may need to adjust monetary policy to manage inflation, impacting interest and exchange rates.
• It can harm international relations: Currency devaluation can strain political and diplomatic ties if perceived as manipulative or unjust. The resulting tension can ignite trade disputes or retaliation, potentially threatening the economic interests or sovereignty of other nations, eroding trust and cooperation and potentially destabilizing international trade rules and institutions.

Example of Currency Devaluation

The 2001-2002 Argentine currency devaluation is a compelling example of the potential ramifications of this economic strategy. In 1991, Argentina adopted a fixed exchange rate system, pegging one peso to the U.S. dollar. This decision initially curbed inflation and stabilized the economy but exposed Argentina to external shocks and fiscal imbalances. By the late 1990s, an appreciating U.S. dollar rendered Argentine exports less competitive and imports more expensive, generating a trade deficit and a recession.

With a high public debt predominantly denominated in U.S. dollars, Argentina defaulted on its debt payments in December 2001 after failed attempts to secure additional financial aid from the IMF. This resulted in abandoning the fixed exchange rate system and letting the peso freely float. Consequently, the peso underwent rapid depreciation, with one peso equating to only 0.25 US dollars by January 2002 – a 75% devaluation.

The devaluation offered mixed results for Argentina. On the upside, the trade balance improved, with exports becoming cheaper and imports pricier. The real value of public debt also decreased. However, the devaluation sparked a sharp inflation increase from rising import prices and escalated domestic production costs. The purchasing power and savings of citizens dwindled, with bank accounts frozen or unfavorably converted from dollars to pesos. The situation triggered political instability and social unrest, leading to public protests against governmental policies and the resignation of several presidents.

This Argentine experience underscores the significant impacts of currency devaluation, emphasizing the need for sound economic policies and institutions to manage exchange rates and public finances. It demonstrates how currency devaluation can affect a country's economic performance, social welfare and political stability.
