China's push to internalize cross-border yuan settlement has been building in volume and participants for years. What changed in early 2026 is that it found a live test case, one defined not by bilateral trade agreements or diplomatic negotiations, but by a conflict-driven chokepoint where dollar rails became operationally unattractive before any policy decision was made. The Strait of Hormuz, through which roughly 20% of the world's traded oil and liquefied natural gas passes, has become the proving ground for whether CIPS, China's Cross-Border Interbank Payment System, can handle politically sensitive settlement that SWIFT-connected banks will not touch.

CIPS Infrastructure | 43% Volume Growth, 1,683 Participants, Still Not SWIFT
The framing of CIPS as a "SWIFT replacement" overstates where the system currently stands. SWIFT remains the dominant global financial messaging network, connecting more than 11,000 institutions across over 200 countries and territories, processing the vast majority of international wire transfers and trade finance messages. CIPS is narrower in scope: it is China's yuan-specific settlement network, designed to clear RMB-denominated transactions without requiring a dollar intermediary or a correspondent bank inside the US financial system.
What CIPS has demonstrated is rapid institutional adoption within its lane. The network processed ¥175.49 trillion in 2024, a 43% increase over 2023. Participant institutions reached 1,683 by May 2025, spanning banks in Southeast Asia, the Middle East, Africa, and Central Asia, most of which maintain CIPS membership precisely because it provides access to yuan settlement without exposure to US dollar compliance requirements. The practical comparison to SWIFT is not one of scale, it is one of regulatory geography: CIPS operates in the spaces where dollar-linked banks will not go.
Two Confirmed Petroyuan Payments | The Hormuz Toll as a Live Test Case
Since mid-March 2026, the Islamic Revolutionary Guard Corps has enforced a transit toll of approximately $1 per barrel on oil tankers passing through the Strait of Hormuz, with payment demanded in yuan routed through CIPS and Kunlun Bank, or in stablecoins. US dollar payments are refused. According to Lloyd's List, at least two confirmed yuan payments for Hormuz transit fees had cleared through CIPS-linked intermediaries by late March 2026, representing the first documented instances of RMB being used as the settlement currency for a mandatory fee on global energy transit.
The geopolitical signaling surrounding the toll has been explicit. Al Jazeera reported that Iran's embassy in Zimbabwe posted publicly that it was time to introduce the "petroyuan" into the global oil market. China's Ministry of Commerce appeared to validate the use of yuan for the payments without formally endorsing the toll structure itself. Iran's National Security Committee has since advanced a draft law to formalize the fee, which would institutionalize the CIPS-or-stablecoin payment requirement at the statutory level.
For Iran, the mechanism serves two functions simultaneously. It generates revenue from a strait it patrols, and it forces global shipping companies to maintain yuan liquidity as an operational necessity rather than a strategic option. Any company that operates tankers through Hormuz now needs a CIPS-accessible yuan balance. That requirement, multiplied across hundreds of shipping operators globally, normalizes RMB as a working capital currency in energy logistics in a way that no bilateral trade agreement could mandate.
Where Dollar Rails Lose Ground First | Sanctions Pressure and Trade Disruption
The Hormuz case illustrates a broader pattern in how de-dollarization actually advances in practice: not through coordinated policy replacement of SWIFT, but through the accumulation of specific trade routes and transaction types where political or sanctions risk makes dollar settlement impractical or legally inadvisable. A shipping company processing a Hormuz toll payment through a US dollar correspondent bank faces potential OFAC exposure for facilitating a payment to an IRGC-linked entity. The same company routing yuan through CIPS and Kunlun Bank faces no US legal jurisdiction at all.
The iron ore market is converging on the same logic from the commodity side. BHP's recent agreement to incorporate the COREX yuan-linked portside index at a 26% weighting in Jimblebar fines contracts represents a parallel shift in commodity settlement, driven by the same underlying dynamic: dollar-denominated pricing in markets where China is the dominant buyer increasingly exposes both sides to US Treasury leverage that neither party wants. See ObjectWire's full coverage of the BHP COREX deal and its implications for the Big Four miners.
SWIFT will not be displaced in the near term. But the Hormuz toll payments and the BHP pricing concession together suggest that the architecture of dollar dominance is being hollowed out at its most politically exposed edges first, exactly the places where US sanctions policy creates costs that dollar-alternative networks do not impose.
