The US-Israel war on Iran is accelerating de-dollarization and America’s decline | Ahmed Moor
The escalating US‑Israel operations against Iran are not only costly in lives and dollars but also accelerating a global move away from the U.S. dollar. Iran’s blockade of the Strait of Hormuz, the use of Chinese yuan for tolls, and the rise of alternative payment systems are eroding the dollar’s d…
The U.S. and Israel’s intensified military actions against Iran have become a catalyst for a broader economic transformation. While the immediate human toll is stark, the financial ramifications—estimated at roughly $12 billion a week for the United States—are equally significant. More importantly, these operations are accelerating a global trend toward de‑dollarization, a process that could reshape international finance and diminish American influence.
What Is De‑Dollarization and Why It Matters
De‑dollarization refers to the gradual reduction of the U.S. dollar’s role as the world’s reserve currency. Historically, after World War II the dollar emerged as the standard because the United States had the largest, most stable economy and a reputation for sound governance. Today, about 60 % of global foreign‑exchange reserves are held in dollars, giving the U.S. a unique ability to borrow at low cost and to impose sanctions through the global financial system.
When other countries begin to hold fewer dollars and instead use local currencies or alternative systems, the demand for the dollar falls. This can raise U.S. borrowing costs, reduce the effectiveness of sanctions, and ultimately weaken American economic power.
Iran’s Strait of Hormuz Blockade and the Shift to Yuan
Iran’s near‑total blockade of the Strait of Hormuz—one of the world’s most critical oil transit routes—has pushed oil and gas prices higher, creating inflationary pressure worldwide. In March, about 100 vessels passed through the strait, roughly the same number that did each day before the U.S. and Israel escalated the conflict. According to the Guardian, Iran is demanding a toll of roughly $2 million from passing ships, but the payment is being collected in Chinese yuan.
Collecting tolls in yuan is more than a logistical choice; it signals a tangible challenge to U.S. dominance. By using a currency that is not the dollar, Iran is encouraging a shift in the global trade network toward alternative currencies. If Asian consumers and traders begin to prefer yuan for oil transactions, the dollar’s real utility will erode over time.
Alternative Payment Systems and the Erosion of U.S. Leverage
Sanctioned countries such as Russia have already responded to U.S. pressure by developing their own payment networks—SPFS and CIPS—that operate outside the SWIFT system and the dollar. These platforms enable ruble‑yuan transactions, effectively bypassing U.S. sanctions. Brazil, India, and South Africa are reportedly working to integrate with China’s system, further expanding the network of non‑dollar transactions.
When a country can conduct international trade without relying on the dollar or SWIFT, the U.S. loses a key tool for enforcing sanctions. The ability to isolate banks and cut off financial flows is a cornerstone of U.S. foreign‑policy leverage. As more nations adopt alternative systems, the U.S. will find it harder to compel compliance from adversaries.
Domestic Consequences for the United States
The U.S. has long benefited from its reserve‑currency status: it can borrow at low rates, fund wars, and spend on infrastructure without immediate fiscal constraints. If the dollar’s dominance weakens, borrowing costs could rise, making it more expensive to service the national debt—currently around $39 trillion.
Higher borrowing costs could force the U.S. to reduce spending or increase taxes, potentially leading to austerity measures. Historically, attempts to cut taxes while borrowing to cover deficits—such as the experience of former UK Prime Minister Liz Truss—have failed because lenders refuse to lend under such conditions. The U.S. will need to rethink its fiscal strategy if it cannot rely on the dollar’s global demand.
What Happens Next?
The trajectory of de‑dollarization depends on several factors: the duration of the U.S.‑Israel conflict, Iran’s ability to maintain the blockade, and the willingness of other nations to adopt alternative currencies and payment systems. If the conflict escalates, the shift away from the dollar could accelerate. Conversely, a diplomatic resolution might slow the trend.
For now, the United States faces a dual challenge: managing the immediate costs of the conflict while preparing for a potential future where the dollar is no longer the unquestioned global standard. Policymakers will need to consider strategies to diversify the U.S. economic base and to strengthen domestic financial resilience.
In the coming months, analysts will watch closely how oil prices, inflation, and global reserve holdings evolve. The outcome will shape not only U.S. fiscal policy but also the broader architecture of international finance.
Key Takeaways
- The U.S.‑Israel war against Iran is driving a global shift away from the dollar.
- Iran’s blockade of the Strait of Hormuz and the use of Chinese yuan for tolls challenge U.S. financial dominance.
- Alternative payment networks like SPFS and CIPS reduce the effectiveness of U.S. sanctions.
- Higher U.S. borrowing costs could force fiscal tightening and reduce global influence.
- The future of the dollar depends on the conflict’s duration and global adoption of non‑dollar systems.
Why it matters
A decline in the dollar’s dominance would alter global financial flows, increase U.S. borrowing costs, and reduce the country’s ability to enforce sanctions—shifting the balance of power in international relations.

Frequently asked questions
What is de‑dollarization?
De‑dollarization is the process of reducing the U.S. dollar’s role as the world’s reserve currency, often by increasing the use of other currencies or payment systems.
How does Iran’s blockade affect global oil prices?
The blockade raises the cost of shipping oil through the Strait of Hormuz, leading to higher global oil prices and inflationary pressure worldwide.
Can the U.S. still enforce sanctions if the dollar loses dominance?
No, the effectiveness of sanctions relies on control of the global financial system; alternative payment networks reduce U.S. leverage.
