Why Do Countries Hold Foreign Exchange Reserves in 2025?

1. Why Should We Care About “Forex Reserves”?

• Foreign exchange reserves aren’t just some obscure central bank matter.
  They affect a country’s economic safety, inflation, currency value, and even how much cash you can exchange when you travel abroad.
• In a world deeply interconnected by globalization, understanding forex reserves is part of understanding a nation’s economic moat.

2. What Exactly Are Foreign Exchange Reserves? Not Just a “Foreign Currency Account”

• Definition:
  Assets held by central banks or monetary authorities in foreign currencies, including USD, EUR, gold, SDRs (Special Drawing Rights), and IMF quota positions.
• Form:
  Not just cash—it also includes foreign government bonds, bills, short-term deposits, and highly liquid investment products.
• Essence:
  State-level “highly liquid foreign currency assets” used to hedge against balance-of-payment crises.

3. The Five Key Purposes of Holding Forex Reserves

1. Stabilizing the Domestic Currency

• When a currency faces depreciation pressure, the central bank can sell foreign reserves and buy its own currency to stabilize the exchange rate.
• Example:
  In 2022, Japan’s central bank intervened to stabilize the yen using reserves amid volatile FX markets.

2. Boosting International Payment Ability

• Reserves act as “insurance” for unexpected import demands, debt repayments, or emergency assistance.
• IMF standard:
  Reserves should cover at least 3 months of imports.

3. Enhancing National Creditworthiness

• Sufficient reserves improve a country’s credit rating and attract foreign investments.
• 2025 data:
  Nations with reserves below 10% of GDP often suffer lower credit ratings.

4. Coping with Capital Flight Risks

• In financial crises, capital outflows can surge. Reserves act as shock absorbers.

5. Managing Returns and National Wealth

• Reserves also generate interest returns, such as holding U.S. Treasuries for yields.
• This explains why China remains a top holder of U.S. government debt.

4. Why Do Countries Buy So Many U.S. Treasuries?

• The U.S. dollar is the global settlement currency—over 88% of international trade uses the dollar.
• U.S. Treasuries are the most liquid and “safest” forex assets.
• Holding Treasuries is a reluctant but strategic move for most central banks.
  It’s not about maximizing return—it’s about safety and liquidity.
• 2025 data:
  China, Japan, the UK, and Luxembourg remain the top four foreign holders of U.S. debt.

5. Who Holds the Most Forex Reserves in 2025? (Unit: USD Billion)

• Worth noting: Hong Kong, while having less in nominal reserves, ranks high in reserves as a percentage of GDP.

6. Can Too Much Reserve Be a Problem?

• Currency Manipulation Accusations:
  The U.S. frequently places high-reserve countries on its “currency manipulation watch list”.
• Low Return Efficiency:
  Over-investing in low-yielding assets like Treasuries may hinder national capital growth.
• Market Distortion:
  Overuse of reserves for FX intervention could distort real market signals.

7. What’s Changing? Global Reserve Trends (2023–2025)

• Subtle De-Dollarization:
  Russia, Iran, and some emerging markets are reducing U.S. debt holdings.
• Gold Comeback:
  2023–2024 saw central banks globally buying gold at record levels.
• Rising Interest in Digital Assets & SDRs:
  The monetary reserve structure is diversifying, but the dollar still dominates.
