Currency Wars, De-dollarisation & Global Reserve Shift: Smart Module for Economics and GS

Currency Wars, De-dollarisation & Global Reserve Shift

US Dollar’s Dominance • Weaponisation of Finance • Rise of Gold & Local Currencies • India’s Rupee Strategy

1. Core Concepts – Currency War, De-dollarisation & Reserve Currency

(a) Currency Wars

Currency war refers to a situation where countries deliberately try to depreciate their currencies (or prevent appreciation) to gain competitive advantage in exports, growth and debt management. It typically involves:

  • Large-scale monetary easing / QE to push interest rates down
  • Foreign exchange intervention by central banks
  • Use of capital controls to manage inflows and outflows
A currency war = competitive devaluation + ultra-loose monetary policy to grab global demand (often a “beggar-thy-neighbour” strategy).

(b) De-dollarisation

De-dollarisation means a reduction in the use of the US dollar in international trade, finance, reserves and payments, and a shift towards other currencies, gold or digital alternatives. It is usually driven by:

  • Fear of US financial sanctions and freezing of reserves
  • Desire to de-risk from dollar volatility and US domestic politics
  • Emergence of regional powers and alternative payment systems

(c) Reserve Currency & Global Reserve Shift

A reserve currency is a currency held in significant quantities by central banks as part of their foreign exchange reserves and used in international transactions. Since World War II, the US dollar has been the dominant reserve currency. However, its share in global reserves has gradually declined, and central banks are diversifying into euro, yen, yuan, smaller currencies and gold.

2. Evolution of Dollar Dominance – From Bretton Woods to Weaponisation

Post-1944, the Bretton Woods system made the dollar the anchor currency, backed by gold. After the 1971 “Nixon Shock” (end of gold convertibility), a petro-dollar system evolved, with oil and key commodities priced in USD. Deep US financial markets, military power and network effects entrenched dollar dominance.

Phase Key Events Implication for Dollar
1944–1971 Bretton Woods; fixed exchange rates; dollar convertible into gold Dollar becomes formal anchor of global system
1970s–1990s End of gold link; oil priced in USD; Eurodollar markets rise Dollar evolves into petro-dollar + financial dollar
2000s–2010s US QE after Global Financial Crisis; China’s rise Talk of currency wars; emerging markets worry about volatility
2020s Sanctions on Russia’s reserves; trade & tech wars; BRICS activism Weaponisation of finance accelerates de-dollarisation efforts
UPSC angle: link “exorbitant privilege” of the dollar with the risk of “exorbitant weaponisation” of sanctions and tariffs.

3. How Do Currency Wars Work in Practice?

(a) Policy Toolkit

Instrument How It Works Intended Outcome
Interest Rate Cuts & QE Large-scale bond purchases push yields down, weaken currency Boost exports, asset prices, growth
FX Intervention Central bank buys foreign currency, sells domestic currency Prevents appreciation, supports exporters
Capital Controls Limits on inflows/outflows, taxes on “hot money” Reduce volatility, preserve autonomy
Tariffs + Financial Sanctions Trade restrictions combined with asset freezes, SWIFT bans Pressure rivals; can fragment monetary system
A currency war is not a formal war; it is a policy race to the bottom in exchange rates and interest rates.

4. Drivers of De-dollarisation in the 2020s

De-dollarisation today is gradual and selective, not a sudden collapse. Major drivers include:

  • Sanctions risk: Freezing of major-country reserves and SWIFT exclusions encourage others to diversify into gold and non-dollar currencies.
  • Geopolitical polarisation: Deepening divides between US-led alliances and blocs like BRICS+ push local-currency trade and new payment systems.
  • US debt & political risk: Rising debt, repeated debt-ceiling dramas, and tariff wars raise questions about long-term safety of dollar assets.
  • Technological change: CBDCs, fintech and alternative cross-border systems make diversification operationally easier.
De-dollarisation is best understood as “de-risking from over-dependence”, not as the overnight replacement of the dollar.

5. Evidence of Global Reserve Shift – What Do the Numbers Show?

(a) Changing Reserve Currency Shares

IMF COFER and central bank data show that the dollar’s share of disclosed official FX reserves has:

  • Fallen from around 70–72% in the early 2000s to about 58% by 2024, and further towards the mid–50s in 2025 (valuation effects plus diversification).
  • The euro stabilised near 20%, while the Chinese renminbi remains small at around 2–3%, though slowly rising.
  • Shares of “other currencies” (NOK, AUD, CAD, etc.) and gold have increased as diversification vehicles.
Currency / Asset Approx. Share in Global Reserves (2024–25) Trend
US Dollar (USD) ~56–58% Gradual decline from ~70% in early 2000s; still dominant
Euro (EUR) ~20% Stable / slight recovery post-Euro crisis
Yen, Pound ~10–12% combined Broadly stable
Chinese Yuan (RMB) ~2–3% Slow but steady rise
Other Currencies ~5%+ Diversification into smaller but stable currencies
Gold (as reserve asset) Separate from COFER but rising sharply Record central bank purchases since 2022

(b) Central Bank Gold Rush

Since 2022, central banks – especially in the Global South – have bought over 1000 tonnes of gold annually, marking the strongest official-sector gold demand in modern history. This is explicitly framed as diversification away from dollar assets and sanctions risk.

Gold has re-emerged as a “neutral reserve asset” in a fragmented world, supporting the narrative of a slow global reserve shift.

6. BRICS, Regional Banks & Alternative Architectures

Alongside reserve diversification, new Southern-led financial architectures have emerged:

  • BRICS & BRICS+: Push for use of local currencies in intra-BRICS trade (e.g., yuan–ruble, yuan–real, rupee-based trade with Russia).
  • New Development Bank (NDB): Equal-voting development bank lending in local currencies, symbolising South–South cooperation.
  • AIIB, regional swap lines, CIPS etc.: Provide non-dollar channels for finance and payments.
  • Debate on a BRICS currency / digital unit: Proposals for a new unit of account or blockchain-based settlement system to reduce dependence on USD in the long run.
Initiative Type De-dollarisation Relevance
BRICS Local Currency Trade Trade settlement in national currencies Reduces need for USD in intra-BRICS trade
NDB & AIIB Multilateral development banks Offer loans in local currencies; diversify funding channels
BRICS Currency Proposals Conceptual – digital / basket currency Long-term idea to challenge dollar’s pricing role
Alternative Payment Systems CIPS, SPFS etc. Reduce vulnerability to SWIFT-based sanctions
So far, these architectures chip away at dollar dominance at the margin rather than replacing it – but they are strategically significant.

7. India’s Perspective – Rupee, De-dollarisation & Strategic Balancing

(a) Rupee Internationalisation Measures

India supports a multipolar currency order but also benefits from the stability of the existing system. Recent steps by RBI and Government include:

  • Framework for Special Rupee Vostro Accounts (SRVA) to allow trade settlement in INR for willing partners (since 2022, with further relaxations in 2025).
  • Allowing surplus rupee balances in SRVAs to be invested in Government securities to make INR holdings more attractive.
  • Broad-based measures to promote rupee use in trade and investments, alongside deepening of GIFT–IFSC as a global financial hub.
India’s strategy is gradual rupee internationalisation – expanding INR use where it is natural, without destabilising macroeconomic fundamentals.

(b) India Between Dollar System & BRICS Push

  • India remains deeply integrated with the dollar-based system (trade, capital inflows, reserves) and cannot suddenly exit it.
  • At the same time, India participates in BRICS, NDB, AIIB and rupee-based trade with Russia and other partners, signalling support for de-dollarisation at the margin.
  • Policy priority: monetary sovereignty + macro stability rather than ideological anti-dollarism.

8. UPSC Prelims Booster – Quick Facts & Trick Statements

Statement UPSC-Type Assessment
(1) De-dollarisation means the US dollar is no longer used at all in world trade. Incorrect – it means reduced dependence, not complete exit.
(2) The US dollar still accounts for the largest share of global FX reserves. Correct – share is falling but remains above 50%.
(3) Central bank gold buying since 2022 is partly motivated by sanctions risk and diversification away from dollar assets. Correct.
(4) De-dollarisation is driven only by BRICS and low-income countries. Incorrect – even advanced economies diversify at the margin for risk management.
(5) A currency war always leads to higher growth for all participating countries. Incorrect – can trigger retaliation, volatility and financial instability.
For Prelims, focus on concept clarity (currency war vs trade war vs de-dollarisation) and factual trends (declining but still-dominant dollar; rising gold and “other currencies”).
