In recent years, the global landscape has undergone significant shifts, driven by unprecedented geopolitical tensions, technological advancements, and economic transformations. These changes have inevitably influenced the structure and function of the international monetary system, reshaping how countries engage in trade, manage currencies, and maintain financial stability.
In the short term, the U.S. dollar's status as the dominant international currency is unlikely to be replaced. However, in the medium to long term, the international monetary system may undergo new transformations. Currently, some representative reform proposals for the international monetary system include the Bretton Woods System III, partially anchored by commodities; an integrated supranational currency system based on Special Drawing Rights (SDR) or digital currencies; and a diversified monetary system based on multiple reserve currencies.
What exactly is an ideal international monetary system?
An ideal international monetary system is a theoretical framework for how countries manage exchange rates, conduct international trade, and regulate cross-border capital flows. It serves to create stability and efficiency in global economic interactions. According to economic scholars like Cohen (1978), such a system should have the following key characteristics:
1.Liquidity: It should provide sufficient international liquidity, allowing countries to trade and settle balances without causing instability or crises. This means having an adequate supply of reliable reserve currencies, like the U.S. dollar or the euro, to facilitate global trade and financial transactions.
2.Stability: It should offer stability in exchange rates and prevent extreme volatility. Stability is crucial for predictable international trade and investment flows, and for preventing speculative attacks on currencies. The system should encourage long-term economic balance without excessive inflation, deflation, or sudden shifts in currency values.
3.Confidence: Participants in the system must have confidence in the reserve currencies and the institutions that manage them. This is essential for smooth international payments and investments. Confidence is often tied to the economic health and policy stability of the country issuing the reserve currency.
4.Adjustability: The system must allow for flexibility in correcting imbalances between countries, such as trade surpluses or deficits. This may involve exchange rate adjustments, capital flows, or other mechanisms to restore balance in a way that does not disrupt the global economy.
An ideal system should address global challenges like currency crises, misalignments in trade balances, and the need for nations to cooperate in their economic policies. In recent times, scholars like Zoltan (2022) have suggested that commodities might play a larger role in future reserve systems, while others suggest that digital currencies or a more diversified reserve currency structure could be part of an evolving international monetary framework.
Characteristics and Inherent Vulnerabilities of the Current International Monetary System
The international monetary system (IMS) plays a crucial role in the global economy, affecting trade, currency management, and financial stability. While it has supported global growth, it faces several challenges that highlight the need for reform.
The current international monetary system (IMS) has some key traits:
1. U.S. Dollar Dominance: The dollar is the main global currency for trade and reserves.
2. Flexible Exchange Rates: Most countries let their currencies fluctuate based on market conditions.
3. Capital Mobility: Money moves freely across borders, enabling global investment.
4. International Institutions: Organizations like the IMF help manage financial stability.
However, there are inherent problems:
1. Over-reliance on the U.S. Dollar: Global stability depends heavily on the U.S. economy.
2. Global Imbalances: Big trade differences between countries create tension.
3. Volatility: Quick capital movement can destabilize smaller economies.
4. No Central Authority: There's no single organization to oversee the entire system.
5. Currency Conflicts: Countries may devalue their currencies to gain trade advantages.
6. Limited Emerging Market Influence: Developing countries often have less say in global decisions.
7. Digital Currency Risks: The rise of digital money could challenge the system's stability.
In short, while the IMS supports global trade, its reliance on the dollar, imbalances, and financial risks show it needs improvement to remain stable.
New Changes in the Global Geopolitical Landscape
Since 2020, political instability in many countries, combined with the escalation of the Russia-Ukraine conflict and heightened tensions in the Middle East, has significantly impacted the global economy and reshaped the geopolitical landscape. The international order is undergoing major adjustments, divisions, and restructuring. As geopolitical dynamics grow more influential, the international monetary system is expected to transform rapidly, entering a phase of intense geopolitical competition.
Key points include:
1. Political and Geopolitical Influence: Political struggles and changes in the global political landscape play a crucial role in shaping the international monetary system. Countries compete for influence in global finance, with national support being essential for the internationalization of a currency.
2. Military Power and Currency Strength: A country’s military power is a key factor in supporting its currency’s internationalization. Historically, the British pound's dominance was tied to the UK's naval power, and the U.S. dollar's central role is backed by U.S. military and political alliances. The euro’s struggle to surpass the dollar is partly due to the European Union’s lack of military strength comparable to the U.S.
3. Political Stability and Currency Confidence: Political stability greatly affects the international monetary system's stability. Increased political stability reduces inflation and exchange rate volatility, boosts confidence in a currency, and strengthens capital control policies, supporting currency internationalization.
In summary, recent geopolitical conflicts and political shifts are accelerating changes in the international monetary system, pushing it toward an era of heightened geopolitical competition.
Proposals for Reforming the International Monetary System
Reforming the international monetary system (IMS) has been a topic of ongoing discussion, especially in light of recent global economic shifts and geopolitical tensions. Several proposals have been put forward to address the system's inherent weaknesses and better adapt it to the demands of a rapidly changing world. The main reform proposals include:
1. Diversification of Reserve Currencies
2. Creation of a Global Currency
3. Strengthening Multilateral Institutions
4. Digital Currencies and Central Bank Digital Currencies (CBDCs)
As early as the beginning of the 21st century, scholars suggested that the future international monetary system might evolve into a "three-island model of global financial stability," with the U.S. dollar, the euro, and the Asian currency zones forming three dominant regions (Mundell, 2000). With the growing international influence of the euro and the increasing economic strength of emerging markets, discussions about a more diversified international monetary system have intensified. Recent trends, such as the Russia-Ukraine conflict, may further push the current system toward increased diversification or even fragmentation.
The characteristics and manifestations of a diversified international monetary system include the following:
1. Multiple Reserve Currencies: In a diversified system, several reserve currencies coexist. As IMF Deputy Managing Director Gita Gopinath (2022) pointed out, Western sanctions may encourage some countries to use non-dollar currencies in global trade, creating smaller currency blocs and diversifying central bank reserve assets. Eichengreen (2022) has also been a strong proponent of diversifying international reserve currencies.
2. Diversification of Cross-Border Payment Systems: Another feature of a diversified international monetary system is the emergence of multiple cross-border payment systems. In addition to the U.S.-dominated SWIFT system, alternatives like China’s CIPS, Russia’s SPFS, and the EU’s INSTEX are developing rapidly.
3. Digital Currencies as a New Dimension: A diversified international monetary system also includes the rise of digital currencies. In February 2021, the People’s Bank of China, along with the Hong Kong Monetary Authority, and the central banks of Thailand and the UAE, launched the multilateral Central Bank Digital Currency Bridge (mBridge) project. The initiative aims to enhance the efficiency of cross-border payments using wholesale central bank digital currencies (CBDCs), which could evolve into a digital currency zone. This system may bypass SWIFT to establish an independent international payment clearing mechanism, strengthening the role of digital currencies and influencing international monetary reform from the perspective of transaction mediums.
Prospects for the Future Reform of the International Monetary System
Currently, the global landscape is facing significant uncertainty, leading to the potential restructuring and adjustment of the international financial order. Considering the driving factors of the international monetary system and a dual analytical framework, it is necessary to assess its future direction.
From the perspective of currency issuance, the foundation for future international currency issuance must consider the needs for global economic development and stability, as well as the dynamics of competition and negotiation between countries. In the current turbulent international environment, there are doubts about whether national credit can continue to support global confidence in international currencies. However, the historical evolution from commodity money to credit money suggests that sovereign credit currencies will continue to play an important role in the international monetary system. The key to determining the direction of this system may be identifying which reserve currencies can garner widespread confidence.
From the perspective of currency competition, the future of the international monetary system faces multiple possible directions—unipolar, parallel, or diversified. In the short term, the U.S. dollar's dominant role as an international currency is unlikely to be replaced, and it may even be strengthened due to Federal Reserve monetary policies and the global demand for safe assets. In the medium to long term, the unipolar U.S. dollar-based system may evolve toward diversification. However, a parallel currency system, as described in the Bretton Woods III scenario, where multiple currencies coexist, may only emerge if geopolitical conflicts lead to global fragmentation. Additionally, a supra-sovereign currency system, dominated by SDRs or digital currencies, is unlikely to be realized in the near term due to design complexities and competition among nations.
There is much debate about the role and positioning of digital currencies in the international monetary system. First, it is important to recognize the limitations of digital currencies—any currency’s status in the international system ultimately depends on the comprehensive strength of the issuing country. Second, while the core drivers of the international monetary system should not be overlooked, the marginal impact of digital currencies cannot be ignored. The current uneven development of the global digital economy may affect the dynamic shifts in national power, influencing the position of a country’s digital currency in the international system. Finally, the direction of digital currencies' impact on the international monetary system remains uncertain.
Digital currencies could weaken the current inertia of using existing international currencies or create a stronger currency substitution effect, potentially reinforcing the existing international monetary system. The final outcome largely depends on the strategic choices made between private and sovereign digital currencies, as well as the form and degree of integration between digital currencies and sovereign currencies. Currently, the technological maturity and policy support for digital currencies in various countries are rapidly evolving, and internal competition among different interest groups regarding their application exists. How digital currencies will ultimately influence the competitive landscape of international currencies remains to be seen.
In conclusion, a more realistic future for the international monetary system may involve regional economic and financial cooperation, with intense competition among international currencies such as the U.S. dollar, euro, British pound, and Chinese renminbi, leading to a trend toward diversification.
