Economic and Political Crisis in Sri Lanka

The economic and political crisis in Sri Lanka serves as a harsh lesson on the financial instability that arises when foreign exchange reserves are depleted. In 2022, Sri Lanka faced a severe crisis with foreign reserves reduced to merely $50 million, insufficient to import essential goods like food, fuel, and medicine. The result was widespread protests, a government losing control, and the nation plunged into chaos.

The root cause extended beyond poor financial management to prolonged fiscal and monetary policy missteps, eroding investor confidence domestically and internationally. Sri Lanka’s case underscores the critical role of foreign exchange reserves in maintaining macroeconomic stability and safeguarding financial sovereignty.

What are Foreign Exchange Reserves?

Foreign Exchange Reserves refer to the financial assets held by a country’s central bank. These assets typically include major foreign currencies (USD, EUR), gold, and other international financial instruments such as government bonds from developed nations.

Acting as a financial “buffer,” foreign exchange reserves play a pivotal role in stabilizing exchange rates, controlling inflation, and supporting international payments. If a national economy were a large ship, foreign exchange reserves would be the backup fuel keeping it steady amid turbulent waves.

7 Reasons Central Banks Need Foreign Exchange Reserves

1. Stabilizing Exchange Rates

When there are sharp fluctuations in foreign currency supply or demand, the central bank can intervene by buying or selling foreign currency to stabilize the exchange rate.

2. Meeting International Debt Obligations

Foreign exchange reserves ensure the ability to pay off maturing foreign debts, preventing the risk of a national default.

3. Supporting International Trade

In a globalized economy, foreign exchange reserves are a crucial funding source for settling import and export transactions.

4. Shielding the Economy from Financial Shocks

Foreign exchange reserves act as a shield, helping nations tackle economic crises or global financial volatility.

5. Boosting Investor Confidence

A substantial amount of foreign exchange reserves increases the confidence of foreign investors, thereby attracting foreign direct investment (FDI) and foreign institutional investment (FII).

6. Regulating Monetary Policy

The central bank can adjust foreign exchange reserves to influence money supply, control inflation, and stimulate economic growth.

7. Safeguarding Economic Sovereignty

Strong foreign exchange reserves reduce dependence on international financial institutions like the IMF.

The Impact of Foreign Exchange Reserves on National Economies

1. Maintaining Macroeconomic Stability

Foreign exchange reserves are fundamental to ensuring macroeconomic stability. Countries with substantial reserves can respond flexibly to emergencies like oil price shocks or trade wars. For instance, during the 2008 global financial crisis, China utilized over $3 trillion in reserves to stabilize its economy and support growth.

2. Stabilizing Exchange Rates

Exchange rate fluctuations can cause significant losses for businesses and individuals. With sufficient reserves, the central bank can effectively intervene, preventing excessive exchange rate volatility.

3. Enhancing Economic Confidence

Large foreign exchange reserves signal robust financial capability. This strengthens trust among citizens and international trade partners. Conversely, low reserves erode confidence, increasing the risk of financial system collapse.

4. Effective Financial Management

Owning foreign exchange reserves is not just a defensive strategy; it also provides policymakers with additional resources to support economic growth and promote national development projects without resorting to international borrowing.

Practical Tip: Individual investors should closely monitor their nation’s foreign exchange reserves, especially when investing in stocks from industries reliant on imports and exports. Low reserves could indicate potential recession risks or tighter monetary policies in the future.

Sri Lanka’s case is a wake-up call but also an opportunity for nations, businesses, and individuals to reassess the importance of foreign exchange reserves—a factor often underestimated yet foundational to financial success.

Management and Differences Between Forms of Foreign Exchange Reserves

Managing foreign exchange reserves is an art of balancing liquidity assurance, asset value preservation, and profit optimization. To achieve this, central banks must develop appropriate asset allocation strategies and utilize various forms of reserves.

Types of Foreign Exchange Reserve Assets

1. Cash and Major Currencies

This is the most common component, typically including USD, EUR, JPY, and GBP. These currencies are highly liquid and easily used in international transactions or market interventions. However, the biggest risk lies in devaluation due to exchange rate fluctuations.

2. Gold

Gold is considered a “safe haven” asset that retains its value over time. However, holding large reserves of gold may pose challenges in quickly converting it into cash. As of 2023, countries have increased their gold reserves, bringing the global total to over 35,000 tons.

3. Foreign Government Bonds

This type of asset provides fixed returns, generating passive income. U.S. Treasury Bonds are a top choice due to their high level of safety.

4. Special Drawing Rights (SDR)

Issued by the IMF, SDRs are supplemental international reserve assets that help diversify portfolios and reduce reliance on a single currency.

5. Other Assets

These include stocks, ETFs, and other high-value financial assets. While they offer higher returns, these assets generally come with greater risks and are less favored for primary reserve purposes.

Impact on the Economy

Inefficient asset allocation can lead to wasted resources. For example, excessive cash reserves reduce profitability, while over-reliance on gold limits liquidity. A lesson from China shows that allocating reserves to U.S. Treasury Bonds (accounting for over 60% of the country’s total foreign exchange reserves) not only provides stable returns but also strengthens economic ties with the U.S.

Risks of Maintaining Large Foreign Exchange Reserves

While large reserves offer financial stability, they also pose significant risks:

1. High Opportunity Costs

Holding large foreign reserves locks up capital that could otherwise be used for economic development or infrastructure projects. For instance, retaining $1 billion in reserves instead of investing in infrastructure could miss the opportunity to create tens of thousands of jobs.

2. Domestic Inflation

As foreign reserves increase, domestic money supply can rise accordingly, leading to inflation risks. In some countries, this policy has caused soaring consumer prices, putting pressure on citizens’ living standards.

3. Non-Profitable Reserves

A significant portion of foreign exchange reserves generates minimal returns. Gold and cash are prime examples—they act as “insurance” rather than growth tools.

4. International Financial Risks

Large foreign reserves are vulnerable to global financial fluctuations, such as rising interest rates in the U.S. or Europe.

Why Is the USD a Safe Haven During Crises?

The USD is regarded as the “king” of foreign exchange reserves for several key reasons:

1. Economic Strength of the U.S.

The U.S. is the largest economy in the world, with a GDP exceeding $26 trillion in 2023, fostering trust among investors.

2. High Liquidity

The USD can be quickly converted and is widely accepted globally, minimizing liquidity risks.

3. Stable U.S. Treasury Bonds

Countries like Japan and China hold trillions of dollars in U.S. Treasury Bonds due to their safety and steady returns.

4. Trust in U.S. Economic Policies

Although U.S. fiscal and monetary policies often spark debates, they are still considered more reliable than those of most other nations.

Could Another Reserve Currency Replace the USD?

As the global economic order evolves, the question of whether another currency could replace the USD as the primary reserve currency is gaining attention.

1. The Euro

The Euro was once expected to be a worthy rival to the USD. However, instability within the Eurozone, particularly during the sovereign debt crisis, has diminished confidence in the currency.

2. The Chinese Yuan (CNY)

China is striving to internationalize the Yuan, but tight government control and regulatory barriers make it difficult for the CNY to become the top choice. Currently, the Yuan accounts for only 3% of global foreign exchange reserves.

3. Digital Assets

Although digital currencies like stablecoins and Central Bank Digital Currencies (CBDCs) are emerging, they are far from achieving the trust and widespread use of the USD.

4. BRICS and New Proposals

BRICS nations (Brazil, Russia, India, China, South Africa) are discussing the development of a common reserve currency. However, differing economic policies and conflicting interests among members pose significant challenges.

Despite various potential alternatives, the USD maintains its dominance due to the U.S.’s economic and political stability. Any replacement of the USD, if it occurs, would take decades.

The Impact of Global Economic Crises on Foreign Exchange Reserves

1. Effects of the COVID-19 Pandemic

The COVID-19 pandemic was a major global economic shock, deeply altering the structure of foreign exchange reserves in many countries. Numerous economies faced declining exports, withdrawal of foreign investments, and surging import demand for essential goods like medical supplies. As a result, many developing nations utilized foreign reserves to support exchange rates, maintain foreign currency liquidity, and import critical goods. For instance, India reduced its reserves by nearly 10% during the peak of the pandemic but managed to maintain stability through effective capital control measures.

Conversely, strong export-driven economies like China increased their reserves as exports of medical supplies and electronics surged in response to rising global demand.

2. Lessons from the 2008 Financial Crisis

The 2008 financial crisis underscored the importance of foreign exchange reserves in dealing with unexpected shocks. Emerging economies like Brazil, India, and Indonesia faced massive capital outflows, creating significant pressure on exchange rates and current accounts.

Since then, many nations have bolstered their foreign exchange reserves as part of a financial defense strategy. For example, Indonesia increased its reserves from $51 billion in 2008 to over $120 billion by 2023 to better prepare for similar crises in the future.

Response Measures

• Increasing Access to International Funds: Countries like Argentina signed currency swap agreements with China to enhance short-term foreign currency liquidity.
• Adjusting Monetary Policy: Central banks raised interest rates to retain capital inflows while selling foreign reserves to stabilize exchange rates.
• Tightening Fiscal Policies: Some nations implemented public spending cuts to reduce pressure on the balance of payments.

The Role of International Financial Institutions

1. The International Monetary Fund (IMF)

The IMF acts as a global “safety net,” providing financial and technical assistance to countries facing foreign exchange reserve difficulties. Key tools include emergency loans like the Flexible Credit Line (FCL) and Special Drawing Rights (SDR).

For instance, during the COVID-19 pandemic, the IMF issued $650 billion in SDRs to bolster financial resources worldwide. Pakistan was among the beneficiaries, using this support to stabilize its balance of payments and ease pressure on its domestic currency.

2. The World Bank (WB) and Regional Organizations

Beyond the IMF, institutions like the World Bank and the Asian Development Bank (ADB) provide concessional loans to support foreign exchange reserves and invest in critical sectors such as infrastructure.

However, reliance on these institutions can challenge financial sovereignty, especially when tied to strict conditions like economic reforms or social spending cuts.

Trends in Foreign Exchange Reserve Development

1. Shift Toward Digital Assets

With advancements in blockchain technology, digital assets are emerging as a new trend in foreign exchange reserve management. Several countries, especially smaller economies, are exploring the integration of Central Bank Digital Currencies (CBDCs) into their reserve strategies.

However, the high volatility and lack of clear regulatory frameworks make these assets unlikely to fully replace gold or government bonds in the near term.

2. Seeking Alternatives to the USD

While the USD remains dominant, there is a growing trend toward diversifying foreign exchange reserves. Many countries are reallocating portions of their reserves to other currencies like the Euro, Yuan, and even gold.

The BRICS bloc has promoted the idea of a common currency to reduce dependence on the USD. Yet, significant economic and political differences among members make this initiative far from realization.

Although these new trends show promise, the USD remains the cornerstone of global reserves due to its unmatched stability and liquidity. Transforming the foreign exchange reserve order will require a combination of technological, political, and economic changes—a process that cannot happen overnight
