The Stealth Erosion of Dollar Dominance: Active Diversifiers and the Rise of Nontraditional Reserve Currencies — Serkan Arslanalp, Barry Eichengreen, and Chima Simpson-Bell, 2022

This IMF paper argues that global dollar dominance is gradually weakening through active reserve diversification by central banks. ⭐

Rather than shifting mainly into the euro, countries are increasingly holding renminbi and smaller “nontraditional” currencies, revealing structural changes in global finance, reserve management, technology, and international monetary power.

1. The dollar’s global dominance is gradually declining through active diversification

2. The shift away from the dollar is broader than simply “China replacing America”

3. Central banks increasingly manage reserves like investment portfolios seeking returns

4. Technological change and market forces are reshaping the global monetary system

⭐ Star Facts (The Stealth Erosion of Dollar Dominance)

• The U.S. dollar’s share of global foreign exchange reserves fell from about 71% in 1999 to 59% in 2021.
• The paper argues this decline was caused by active diversification by central banks, not by accidental exchange-rate or interest-rate movements.
• Only about one quarter of diversification away from the dollar went into the Chinese renminbi. About three quarters flowed into smaller “nontraditional” currencies.
• “Nontraditional” reserve currencies include:
  • Australian dollar
  • Canadian dollar
  • Swiss franc
  • South Korean won
  • Singapore dollar
  • Swedish krona.
• The euro was widely expected to become a major challenger to the dollar after its creation, but its reserve share largely stagnated instead of replacing dollar dominance.
• China expanded renminbi influence through:
  • Belt and Road investments
  • currency swap agreements
  • official clearing banks
  • SDR basket inclusion
  • digital currency development (e-CNY).
• In the early 2000s, countries often had to buy U.S. dollars first before converting into smaller currencies because dollar markets were the cheapest and most liquid.
• Electronic trading systems and automated market-making technology reduced the need to route transactions through dollars, making smaller currencies easier to trade directly.
• Central banks increasingly divide reserves into:
  • a liquidity tranche for emergencies
  • an investment tranche seeking higher returns.
• Low or near-zero interest rates on U.S., European, Japanese, and British government bonds pushed reserve managers to seek better returns elsewhere.
• The paper identifies 46 “active diversifiers”—countries holding at least 5% of reserves in nontraditional currencies by 2020.
• The authors argue the global monetary system is becoming more multipolar, meaning power is spreading across multiple currencies rather than concentrating overwhelmingly in one.
