石油人民幣戰略對全球金融市場的影響

人民幣在全球石油貿易中的穩步崛起，不僅僅是商品計價方式的轉變，而是北京一項深思熟慮、跨越數十年的戰略，旨在避免美國金融槓杆的影響，並藉此有系統地侵蝕石油美元體系的根基。

這個戰略是在一個大背景下──中國歷史性的能源轉型──展開的。中國在可再生能源和電動汽車領域的巨大投資，正導致其石油需求進入平台期並開始結構性下降。這產生了一個戰略悖論：中國在最依賴石油進口時，盡最大努力爭取人民幣國際化，以換取能源安全，但隨着中國邁向能源獨立自主，其推動石油人民幣的需求也隨之減弱，在地緣政治衝擊下，最大地創設了有限的窗口。

筆者認為，石油人民幣戰略只是在2024至2032十年間，一種過渡性工具，以期實現特定的地緣政治目標。2026年的伊朗衝突是一個催化劑，加速了這一關鍵窗口期內的行動。

美元霸權的緩慢衰落

美元作為世界主要儲備貨幣的地位，在過去20年中一直緩慢地被侵蝕。美元在全球外匯儲備份額已從2001年的71%下降至2024年底的約58%（註1）。這並非崩潰，而是一種穩定的轉移。

中國的目標是希望捕捉這個日趨多樣化的需求。從人民幣跨境支付系統（2015年，註2）到石油人民幣期貨合約的推出（2018年，註3），以及沙特阿拉伯加入mBridge數位貨幣項目（2024年，註4），這些主要發展反映了中國正審慎、按步就班構建實踐石油人民幣戰略的基礎建設。

香港作為離岸引擎

香港是驅動石油人民幣國際化不可或缺的離岸引擎，因為它擁有全球最大的離岸人民幣資金池（約1萬億元人民幣，註11），處理絕大部分人民幣貿易結算（2024 年達15萬億元人民幣，註11），並正在開拓支撐石油人民幣的數位貨幣基礎設施（mBridge、Ensemble 項目，註14）。香港為連繫中國經濟與全球市場提供了全端解決方案。

石油美元循環瓦解

石油美元體系的核心機制──石油出口國將美元收入回流至美國庫房──正在崩潰。隨着石油貿易轉向人民幣，這種資本自動流入美國國債的趨勢正在減弱。

這在中國自身的投資組合中尤為明顯。自2013年達到近1.3萬億美元的峰值以來，中國官方持有的美國國債到2025年12月已降至6835億美元（註5），而其黃金儲備則增加了一倍以上（註6、7）。

戰略悖論：石油需求峰值與石油人民幣終局

中國作為全球最大石油進口國是實踐石油人民幣戰略的前提，然而，這一地位正在改變，中國正在執行歷史上速度最快、規模最大的能源轉型，這從根本上改變了長期策略。

一、綠色長城：自2009年北京的沙盤推演（參閱〈危機中的世界：十年前沙盤推演如何預測2026年地緣政治格局〉）以來，中國可再生能源生產一直呈指數級增長。截至2025年3月，其風能和太陽能的裝機容量首次超過煤炭，達到1800吉瓦以上（註16、21）。

二、石油需求峰值：中國的能源轉型現正直接影響石油消耗，主要是透過交通工具的電氣化。隨着新能源汽車在2025年新車銷量中的佔比超過一半（註17），交通領域的石油需求已進入平台期。國際能源總署和中國石油經濟技術研究院預計，中國的石油總需求將在2027至2030年間達到頂峰，隨後進入永久性下降（註18、19）。電動汽車已減少了每日逾150萬桶的石油消耗（註20）。

三、巔峰的槓杆窗口期：這創造了一個戰略悖論，中國的石油進口依賴度在2024年達到73%的峰值後開始下降；與此同時，以人民幣結算的石油貿易比例正在迅速上升。在大約2024至2032年這段期間，預料中國的石油進口依賴度仍然很高，同時石油人民幣的基礎設施已發展成熟，形成槓杆的巔峰。在這段時間內，中國既擁有最強動機（能源安全），也擁有最大手段（市場規模）來促使貿易夥伴採用人民幣。

2009至2035年，預料中國的石油進口依賴度仍然很高，同時石油人民幣的基礎設施已發展成熟。

其後，隨着中國石油進口逐漸萎縮，且能源結構由國內可再生能源主導，其在全球石油市場的槓杆力將會減弱。因此，石油人民幣戰略並非一項無限期的計劃，而是一個須在此時限內果斷使用的工具。

伊朗危機作為催化劑

2026年的伊朗衝突是一個強大的催化劑，但它只在能中國進行石油人民幣槓杆的有限窗口期內發揮作用——為北京提供了完美的理由，即因敏銳體現美元體系的風險，加速跟能源夥伴一起去美元化。

石油人民幣的崛起並不預示美元即將崩潰，它只反映了美元不受挑戰之霸權地位的終結，以及多極貨幣秩序的興起。唯至關重要的是，它是一個具保質期的戰略工具，中國正利用其暫時作為全球不可或缺的石油進口國地位，構建一個比倚賴進口石油更持續的平行金融體系，而香港則擔任主要的離岸建築師。

The Petroyuan Strategy: A Deep Dive into its Implications for Global Financial Markets

The steady rise of the Chinese yuan in global oil trade is not merely a shift in commodity invoicing. It is the visible manifestation of a deliberate, multi-decade strategy by Beijing to insulate itself from US financial leverage and, in doing so, to methodically erode the foundations of the petrodollar system. This report analyzes the profound implications of this shift for global financial markets.

However, this strategy is unfolding against an even larger backdrop: China's historic energy transition. The country's massive investment in renewable energy and electric vehicles is causing its demand for oil to plateau and begin a structural decline. This creates a strategic paradox: China's leverage to internationalize the yuan for energy security is greatest during its period of peak oil import dependency. As it moves towards energy independence, its need to push the petroyuan diminishes, creating a finite window of maximum geopolitical leverage.

This report argues that the petroyuan strategy is a transitional tool, being deployed most forcefully in the current decade (2024–2032) to achieve specific geopolitical goals before its underlying strategic imperative fades. The 2026 Iran conflict is a catalyst that accelerates actions within this critical window.

The Slow Decline of Dollar Dominance

The dollar's status as the world's primary reserve currency has been slowly eroding for two decades. Its share of global foreign exchange reserves has fallen from 71% in 2001 to approximately 58% by the end of 2024 [1]. This is not a crash, but a steady drift.

China’s strategy is to capture a significant portion of this diversifying demand. The timeline of key developments shows the methodical, step-by-step construction of the necessary architecture, from the CIPS payment system (2015) [2] to the launch of the petroyuan futures contract (2018) [3] and the inclusion of Saudi Arabia in the mBridge digital currency project (2024) [4].

Hong Kong: The Offshore Engine of the Petroyuan Strategy

Hong Kong is the indispensable offshore engine driving the petroyuan's internationalization. It hosts the world's largest offshore RMB liquidity pool (around RMB 1 trillion) [11], handles the vast majority of RMB trade settlement (RMB 15 trillion in 2024) [11], and is pioneering the digital currency infrastructure (mBridge, Project Ensemble) that will underpin the petroyuan's future [14]. By connecting China's capital-controlled economy with global markets, Hong Kong provides the full-stack solution for the strategy.

The Unwinding of Petrodollar Recycling

The petrodollar system's core mechanism—oil exporters recycling dollar revenues into US Treasuries—is breaking down. As oil trade shifts to the yuan, this automatic flow of capital into US debt diminishes.

This is evident in China's own portfolio. Since peaking at nearly $1.3 trillion in 2013, China's official holdings of US Treasuries have fallen to $683.5 billion by December 2025 [5], while its gold reserves have more than doubled [6, 7].

The Strategic Paradox: Peak Oil Demand and the Petroyuan Endgame

The entire petroyuan strategy is predicated on China's status as the world's largest oil importer. However, this status is temporary. China is executing the fastest and largest energy transition in history, which fundamentally alters the long-term calculus.

The Green Great Wall: Since the 2009 Beijing simulation, China's growth in renewable energy has been exponential. As of March 2025, its installed capacity of wind and solar power surpassed that of coal for the first time, reaching over 1,800 GW [16, 21].

Peak Oil Demand: This energy transition is having a direct impact on oil consumption, primarily through the electrification of transport. With the share of New Energy Vehicles (NEVs) in new car sales exceeding 50% in 2025 [17], oil demand for transport has plateaued. The IEA and CNPC ETRI project that China's overall oil demand will peak between 2027 and 2030 before entering a permanent decline [18, 19]. The EV fleet is already displacing over 1.5 million barrels per day of oil consumption [20].

The Peak Leverage Window: This creates a strategic paradox. China's oil import dependency, after peaking at 73% in 2024, is now beginning to decline. Simultaneously, the share of its oil trade settled in yuan is rising rapidly. The period where import dependency is still high while the petroyuan infrastructure is mature—roughly 2024 to 2032—represents a peak window of leverage. During this time, China has both the maximum motive (energy security) and maximum means (market size) to compel its trading partners to adopt the yuan.

After this window, as China's oil imports shrink and its energy mix is dominated by domestic renewables, its leverage in global oil markets will wane. The petroyuan strategy is therefore not an infinite project, but a tool to be used decisively within this timeframe.

Conclusion: The Iran Crisis as a Catalyst in a Closing Window

The 2026 Iran conflict is a powerful catalyst, but it is a catalyst acting within the finite window of China's peak petroyuan leverage. The crisis provides the perfect justification for Beijing to accelerate its de-dollarization efforts with its energy partners, who are now acutely aware of the risks of the dollar system.

The rise of the petroyuan does not signal the imminent collapse of the dollar. It signals the end of the dollar's uncontested hegemony and the rise of a multipolar currency order. But crucially, it is a strategic tool with a shelf life. China is using its temporary position as the world's indispensable oil importer to build a parallel financial system that will outlast its own dependence on foreign oil, with Hong Kong serving as its primary offshore architect.
