At the ground level, the mechanics of monetary fragmentation are identifiable through shifts in financial systems, banking reconfiguration and the distribution patterns of global capital flows. When considering evolving financial relations, the concept of multipolarity involves emerging geopolitical dynamics, emanating in structural shifts across the international ecosystem. We identify the key drivers of this shift and draw parallels between states, regions, and institutions associated with establishing novel monetary relations.
The Core of Multipolarity
The U.S. financial and military network remains at the heart of the contemporary geo-economic order and financial architecture – a legacy sustained since the mid-20th Century. However, in the last couple of decades, a growing theme within academic research, private analysis, and inter-governmental studies has placed greater emphasis on the shift towards a more multipolar world order. Multipolarity integrates both theoretical and empirical analysis to conceptualise the emerging economic, geopolitical, financial, and security networks established by increasingly competitive regional and continental spheres of influence, subsequently challenging the hegemonic status of the US.
The notion of de-globalisation and de-dollarisation are accommodating theoretical pillars that tie together the notions of multipolarity and monetary fragmentation. They are mostly speculative tools and identify the consequences of financial disintegration and frictions between international markets. The emergence of polycentric institutional networks integrating themselves across the global economy exemplifies the gradual strengthening of multiple centres of influence. This includes the rise of the BRICS+, the formation of the Belt and Road Initiative, successes within the African Development Bank, developments in the Eurasian Economic Union and the Collective Security Treaty Organisation, as well as the adaptive measure made to circumvent Western-centric sanctions through new innovative financial messaging systems. Notwithstanding the merits of these organisations, these measures demonstrate new pathways for the distribution and circulation of financial capital.
The Three Key Drivers
Neither multipolarity nor monetary fragmentation is driven by a single force, but through a set of interacting mechanisms. Each of the three core drivers operate through different channels, but collectively contribute to a reconfiguration of cross-border financial activity.
Geopolitical Risk
Rising geopolitical tensions increase uncertainty around cross-border trade and finance. In response, countries and firms reduce exposure to politically distant partners, shift flows toward aligned economies, and diversify reserve holdings. These adjustments are largely precautionary. Rather than signalling a coordinated shift away from the global system, they reflect efforts to reduce vulnerability to disruptions in trade, finance, and payment access. Over time, this can contribute to more regionalised financial flows and a gradual diversification of currency use.
Sanctions and Tariffs
Sanctions and tariffs translate geopolitical tensions into constraints on financial access and trade. The 2022 freezing of Russian foreign reserves marked a key inflection point, showing that access to reserve assets may depend on political alignment and strengthening incentives to diversify reserves and payment arrangements.
Tariffs also have implications for exchange rate dynamics, a key transmission channel of monetary policy with implications for inflation and financial stability. These effects are not uniform: exchange rate responses to shocks can be non-standard, leading to different inflation and balance sheet outcomes across countries. One example is that reserve currency issuers, emerging markets, and more constrained economies face distinct adjustment pressures.
Following "Liberation Day" tariffs, the dollar depreciated – contrary to standard theory. The evidence points to foreign investors reallocating their equity portfolios away from U.S. equities as the underlying driver. This episode provides a real-time illustration of the broader shift, raising questions not only about the conditional use of the dollar but also about its reliability as a store of value and reinforcing incentives to diversify currency exposures.
Financial Decentralisation
Financial digitalisation and Decentralised Finance (DeFi) are distinct but deeply connected phenomena ongoing within global monetary science. The former focuses on the technological developments paired with financial sector innovations that are shaping the digital economy, from digital wallets and Open-banking APIs, to systemic shifts in blockchains, crypto-assets, and Central Bank digital currencies.
Whereas, the mechanics of DeFi refer to how these technological developments are facilitating peer-to-peer (P2P) transactions. This method of capital transfers is gradually restructuring monetary relations, excluding financial central authorities, reducing the role and insight of Central Banks, commercial banks, and financial institutions. In principle, DeFi represents less financial unity between its major agents and opens an additional dimension of risk and monetary disintegration.
An example that ties these three drivers together is the prohibition of Russian banks using the SWIFT payment system, encouraging major adaptations. The Kremlin has subsequently advanced the role of the Russian System for Transfer of Financial Messages (SPFS), and China’s Cross-Border Interbank Payment System (CIPS) for cross-border payments, accompanied by ‘A7A5’, a Ruble-backed stablecoin used to circumvent Common High Priority Items (CHPI).
