Commerzbank's FX and Commodity Research Head Thu Lan Nguyen has assessed Iran's proposal to levy Strait of Hormuz tolls in Renminbi (CNY) and concluded it is unlikely to catalyze a significant shift toward a petroyuan system. The analysis highlights structural challenges, including limited Chinese demand for Iranian oil, geopolitical tensions, and the entrenched role of the US dollar in global energy trade. While the proposal signals China's interest in diversifying its currency usage, the report underscores that existing trade dynamics and sanctions will hinder widespread adoption of the yuan for energy settlements.

For markets, this development could influence perceptions of the yuan's internationalization but is unlikely to disrupt the dollar's dominance in energy markets. Traders should monitor how China and Iran navigate sanctions and whether alternative payment mechanisms emerge. The outcome may also impact yuan-dollar exchange rate volatility, particularly if China increases efforts to promote its currency in regional trade.

Looking ahead, investors should watch for shifts in China's energy procurement strategies or regional agreements that could bypass Western financial systems. The report suggests that while the petroyuan remains a long-term aspiration, immediate materialization is improbable. Key focus areas include China-Iran trade volumes, sanctions relief, and the role of digital currencies in cross-border transactions.
