How Saudi Arabia and China Are Reshaping Global Payments With mBridge

The Architecture Behind the World's Next Payment Revolution

For most of recorded financial history, the nation that controls the dominant payment infrastructure controls the terms of global trade. The transition from the British pound's dominance to the dollar's ascendancy after Bretton Woods was not simply a political event. It was an infrastructure shift. When the rules of the road changed, so did everything else: trade pricing, reserve composition, and ultimately the purchasing power of ordinary citizens in every corner of the world. Today, a comparable shift is quietly underway, and its most visible expression is the Project mBridge Saudi Arabia China payment system.

Understanding mBridge requires setting aside the idea that this is merely a technical fintech experiment. What is being constructed is an entirely parallel monetary operating system, one that could structurally reduce global dependence on dollar-denominated payment infrastructure for the first time in more than half a century. The evolving geopolitical metals landscape provides important context for understanding why these shifts are accelerating now.

What Is Project mBridge and How Does It Actually Work?

Project mBridge is a multi-central-bank digital currency (mCBDC) platform built on distributed ledger technology (DLT). Its core function is to enable real-time, peer-to-peer cross-border payments and foreign exchange settlement directly between participating central banks, bypassing the correspondent banking networks that currently underpin international dollar flows.

The distinction matters enormously. The existing global payment architecture, anchored by the SWIFT messaging network, does not actually settle transactions. SWIFT tells banks where money is going. Settlement itself runs through a chain of correspondent banks, often multiple intermediaries, each holding dollar-denominated accounts. This creates delays of one to three business days, layered transaction costs, and critically, multiple choke points where US regulatory enforcement can intercept or freeze flows.

mBridge eliminates this chain entirely. Using its own distributed ledger, the mBridge Ledger (mBL), participating central banks can transact directly with each other in their own wholesale central bank digital currencies (CBDCs), settling in real time without dollar intermediation.

The Difference Between Wholesale and Retail CBDCs

A common misconception conflates wholesale CBDCs with the retail digital currencies that governments might one day issue to consumers. They are structurally different instruments. Retail CBDCs are designed to replace physical cash in everyday transactions. Wholesale CBDCs, like those used in mBridge, are settlement assets used exclusively between financial institutions and central banks. mBridge operates entirely at the wholesale level, making it an institutional infrastructure tool rather than a consumer payment product.

The Founding Participants and Institutional Structure

The Bank for International Settlements Innovation Hub played a foundational co-development role from the project's inception, lending the initiative significant institutional credibility in its early stages. However, the BIS formally exited the project in mid-2024, a development explored in detail below.

From Pilot to Minimum Viable Product: The Development Timeline

mBridge's progression from a conceptual framework to a functional payment system moved through several structured phases:

1. 2019–2021: Conceptual development and initial research collaboration between the BIS Innovation Hub and founding central banks.
2. 2022: Pilot transactions conducted involving real-value cross-border transfers between participating institutions.
3. 2023: Expanded technical testing and governance framework development.
4. Mid-2024: mBridge declared minimum viable product (MVP) status, confirming it can process real-value transactions in a controlled operational environment.

Reaching MVP status in payment infrastructure terms is a significant threshold. It means the system has moved beyond theoretical capability into demonstrated, real-value transaction processing, even if full commercial deployment at scale has not yet been announced.

Saudi Arabia's Entry: A Structural Signal, Not a Technical Footnote

Saudi Arabia's elevation from observer to full participant in mBridge is one of the most consequential geopolitical financial developments of the decade, and it has received remarkably little mainstream coverage relative to its significance.

The Petrodollar Framework: A 50-Year Arrangement Under Strain

The relationship between Saudi Arabia and the US dollar stretches back to the early 1970s. When President Nixon severed the dollar's link to gold in 1971, the end of the gold standard created an urgent need for a new mechanism to maintain global demand for US currency. The arrangement that emerged tied oil pricing and settlement to the dollar. Since virtually every oil-importing nation needed dollars to purchase energy, this effectively created a structural, indefinitely renewable demand for US currency. The dollar was no longer backed by gold. It was backed by oil.

That framework is now showing visible cracks. Over recent years, a growing share of oil transactions involving Saudi Arabia and its Asian trading partners have occurred outside the traditional dollar-only settlement model. Saudi Arabia's full participation in the Project mBridge Saudi Arabia China payment system signals a deliberate expansion of its financial options, rather than an abrupt break from its historical alignment. Furthermore, growing concerns about trust in the US dollar are accelerating this diversification process across multiple fronts.

The China-Saudi Bilateral Trade Relationship

China is Saudi Arabia's largest trading partner by volume, with bilateral trade encompassing crude oil, refined products, petrochemicals, and manufactured goods. The scale and trajectory of this relationship create a natural institutional rationale for payment infrastructure that reduces friction, cost, and third-party currency exposure. Every transaction currently routed through dollar correspondent banking introduces exchange rate risk, processing fees, and settlement delays that neither party requires when alternative infrastructure exists.

The Gold Corridor: Physical Settlement Alongside Digital Rails

One of the less widely discussed dimensions of the China-Saudi financial relationship is the development of physical gold settlement capacity. Reports indicate that China has been establishing gold vault infrastructure within Saudi Arabia's borders as part of a broader network of commodity-linked settlement facilities with key partner nations. This development is not incidental. It creates the physical infrastructure for commodity trades, including energy transactions, to be settled in gold rather than exclusively in fiat currencies.

The strategic logic is layered. Digital payment rails like mBridge handle the messaging and settlement of currency flows. Physical gold infrastructure provides an alternative settlement asset entirely outside any nation's monetary policy jurisdiction. Together, these two systems create compound pressure on dollar demand from both the transactional and the reserve asset dimensions simultaneously. The role of gold in the monetary system is consequently becoming more relevant than at any point since the Bretton Woods era.

How mBridge Compares to SWIFT: A Structural Analysis

China's CIPS System: The Complementary Layer

mBridge does not operate in isolation. China's Cross-Border Interbank Payment System (CIPS) functions as a SWIFT-equivalent messaging infrastructure for yuan-denominated transactions. Where SWIFT routes messages through dollar-dependent correspondent networks, CIPS provides an alternative messaging layer aligned with renminbi settlement.

CIPS and mBridge serve complementary rather than competing functions. CIPS handles the messaging instructions for yuan-based transactions. mBridge provides the settlement rails for multi-currency CBDC transactions between central banks. According to Reuters reporting on the platform's growth, the escalation of geopolitical tensions has demonstrably accelerated CIPS transaction volumes as nations sought alternative channels for time-sensitive payments.

What is quietly taking shape in the background is an alternative financial systems arms race, involving not just China, but the UAE, European institutions, and a growing cohort of emerging market economies all building redundant payment infrastructure simultaneously.

The Fragmentation of Global Payment Networks

The global payment landscape is no longer converging toward a single dominant system. It is fragmenting. Competing infrastructure projects now include:

• CIPS (China): Yuan-denominated messaging alternative to SWIFT
• SPFS (Russia): Russia's domestic alternative to SWIFT, developed following 2014 sanctions
• mBridge (Multi-central bank): Real-time CBDC settlement platform
• EU payment sovereignty initiatives: European efforts to reduce transactional dependence on US-controlled infrastructure

The strategic logic behind building multiple parallel systems is redundancy. Nations are not betting on a single alternative winning. They are ensuring that no single point of failure, or sanction, can sever their access to the global payment system entirely.

The BIS Exit: What the Official Explanation Leaves Out

The Bank for International Settlements occupies a unique position in global finance, often described as the central bank of central banks. Its early involvement in mBridge provided the project with a layer of institutional legitimacy that no individual participating nation could replicate.

In mid-2024, the BIS announced its withdrawal from active mBridge development. The official position was that the project had reached MVP status, fulfilling the BIS's incubation mandate and rendering further involvement unnecessary.

That explanation is formally plausible but contextually incomplete. The withdrawal coincided directly with escalating concern among Western governments about mBridge's potential to structurally reduce the effectiveness of dollar-denominated financial sanctions. The timing was not coincidental. Years of resource investment across multiple central bank participants do not typically conclude with an abrupt exit precisely at the moment a project becomes operationally viable, unless external pressure plays a role.

The BIS's then-general manager formally denied that external pressure influenced the decision. What is observable without speculation is that the exit occurred at a moment of maximum geopolitical sensitivity, and that mBridge has continued its development trajectory without BIS participation.

What This Means for the US Dollar's Reserve Currency Status

Quantifying the Erosion

The dollar's share of global foreign exchange reserves has been declining for more than two decades, according to IMF COFER data:

• 2000: Approximately 71% of global FX reserves held in USD
• 2024: Approximately 57–58%, with trajectory pointing toward sub-50% thresholds
• Direction of travel: Consistent downward movement, with acceleration visible in post-2022 data

This erosion matters because of what economists call the dollar's exorbitant privilege. When global trade is settled in dollars and foreign central banks hold dollars as reserves, there is perpetual external demand for US currency and US Treasury bonds. This external demand allows the United States to finance its deficit at lower interest rates than would otherwise be possible and to run debt levels that would be unsustainable for any other nation. As of 2025, US national debt has surpassed $36 trillion.

The Two-Stage Inflation Transmission Mechanism

Reduced global dollar demand does not immediately translate into domestic price increases. The transmission mechanism operates across two phases:

Stage one involves the initial inflationary impulse from domestic monetary expansion, the money printing and quantitative easing episodes that most people are already familiar with from 2020–2022.

Stage two is the externally driven inflationary wave that arrives when reduced foreign demand for dollars weakens the currency's purchasing power against imports. Historical precedent from prior reserve currency transitions, including the British pound's decline after World War II and the earlier contraction of Dutch guilder dominance, consistently shows the second wave as more structurally persistent and harder to resolve through conventional monetary policy.

Central Bank Gold Purchases: The Reserve Asset Substitution in Progress

The pattern is unambiguous. Non-Western central banks are systematically substituting gold for US Treasuries as their preferred reserve asset. This is occurring simultaneously with the development of alternative payment infrastructure, which is not coincidental. Furthermore, central bank gold demand at these levels represents a deliberate, coordinated strategy to reduce dependency on the dollar-denominated financial system across both reserve composition and transactional infrastructure.

How Close Is mBridge to Full Operational Launch?

No official launch date has been publicly announced. However, publicly available information indicates the platform is in advanced preparatory stages following its MVP declaration. Several factors are compressing the development timeline:

• Geopolitical urgency: Escalating tensions in the Middle East, particularly involving Iran, have increased demand among regional trading partners for non-SWIFT payment channels.
• Sanctions-driven adoption acceleration: Historical patterns consistently show that sanctions-related payment disruptions accelerate the adoption of alternative infrastructure among affected and adjacent nations.
• Participant expansion: Additional central banks moving from observer to full participant status signal growing institutional confidence in the platform's viability.

When mBridge achieves full operational scale, the immediate structural consequences would include:

• Significant reduction in correspondent banking revenue derived from dollar intermediation
• Material weakening of the US Treasury's ability to enforce secondary financial sanctions through payment system exclusion
• New settlement options for commodity exporters, enabling oil, gas, and critical minerals to be priced and settled outside the dollar framework

The Cable-to-Streaming Framework: Understanding Monetary System Transitions

One of the most useful analytical frameworks for understanding how dominant monetary infrastructure gets displaced is the transition from cable television to streaming. Cable was once entirely dominant. No credible analyst predicted its marginalisation. However, streaming emerged, offered genuine alternatives, gradually improved its capabilities, and then accelerated past a tipping point.

Cable did not disappear overnight. It did not disappear at all, in absolute terms. But its centrality collapsed. The vast majority of viewing shifted to the alternative. The same pattern characterises every prior reserve currency transition in recorded history. The British pound did not vanish in 1944. It continued to function. But its role as the organising centre of global monetary architecture was displaced incrementally, then suddenly.

The key insight is that these transitions have non-linear acceleration points. Progress appears gradual until it does not.

What Everyday Investors Should Be Watching

For individuals seeking to understand the practical implications of these structural shifts, several indicators serve as leading signals worth monitoring:

• Dollar share of global FX reserves: A sub-50% reading would represent a historic structural inflection point, not yet reached but directionally approaching
• CIPS transaction volume growth: Rising volumes indicate real-world bypass of SWIFT infrastructure accelerating
• Saudi-China trade settlement currency data: Shifts in invoice currency for energy transactions are among the earliest observable indicators
• Central bank gold purchase data: Continued record-level accumulation signals sustained institutional hedging against dollar reserve erosion
• mBridge participant expansion: New central bank entrants signal growing confidence and approaching operational readiness

Asset Classes Under Structural Pressure

In an environment where dollar reserve status is declining and alternative payment infrastructure is maturing, certain asset classes face particular structural headwinds:

• US Treasury bonds: Subject to demand risk as foreign central banks reduce accumulation and substitute gold
• Dollar-denominated savings instruments: Exposed to real purchasing power erosion through the second-stage inflation transmission mechanism
• Fixed annuities and nominal bonds: Structurally vulnerable to sustained inflationary environments driven by currency depreciation

Hard assets, geographically diversified financial exposure, and commodity-linked positions have historically served as partial hedges during reserve currency transition periods. Gold and silver, in particular, have functioned as non-sovereign stores of value across every prior monetary system transition on record.

Frequently Asked Questions: Project mBridge and Dollar Dominance

What is Project mBridge in simple terms?

mBridge is a digital payment platform built by multiple central banks that allows participating nations to transfer value directly using their own central bank digital currencies, without requiring US dollars or the SWIFT messaging system as intermediaries.

Is mBridge operational yet?

As of mid-2024, mBridge reached minimum viable product status, confirming it can process real-value transactions in a controlled environment. Full-scale commercial deployment has not been announced, but the platform is described as being in advanced preparatory stages.

Why did Saudi Arabia join mBridge?

Saudi Arabia's central bank elevated its status from observer to full participant in 2024. The move reflects a broader strategic diversification of Saudi Arabia's financial infrastructure, motivated by the economics of reducing transaction costs and expanding settlement options for its extensive trade relationship with China and other Asian economies.

Does mBridge threaten the US dollar?

mBridge does not represent an immediate existential threat to the dollar's reserve status. However, it contributes materially to a structural trend of dollar demand erosion by providing alternative settlement infrastructure and reducing the technical dependency on dollar-based correspondent banking.

Why did the BIS exit mBridge in 2024?

The BIS officially stated it exited after mBridge reached MVP stage, characterising the departure as the natural conclusion of its incubation mandate. The withdrawal coincided with significant Western scrutiny of the platform's sanctions-circumvention implications, though the BIS denied external pressure influenced the decision.

How does mBridge differ from SWIFT?

SWIFT is a messaging network that communicates payment instructions without settling transactions itself. mBridge integrates both messaging and real-time settlement, eliminates correspondent bank intermediaries, and operates natively across multiple central bank digital currencies rather than routing through dollar-denominated accounts.

The Geopolitical Stakes: A Multi-Polar Financial Architecture

The Project mBridge Saudi Arabia China payment system does not exist in isolation. It is one component of a broader, multi-dimensional strategy being pursued by BRICS-aligned nations to reduce dollar centrality across three interconnected domains: payment infrastructure, commodity pricing, and reserve asset composition.

Progress in each domain compounds the others. Alternative payment rails make non-dollar commodity pricing technically feasible. Non-dollar commodity pricing reduces the structural demand for dollar reserves. Reduced dollar reserve accumulation weakens the Treasury market and increases US borrowing costs. Each incremental advance creates conditions that make the next advance easier to implement.

The pace of this process should not be underestimated simply because it is not proceeding loudly. The most consequential structural changes in monetary history have always advanced quietly, through institutional decisions made in central banks and finance ministries rather than through dramatic public announcements, right up until the moment they became impossible to ignore.
