[Beginner’s Investment Guide] “Relying Only on the Dollar Is Dangerous?” BRICS De-Dollarization and How to Protect Your Portfolio

The “oil settlement currency war” happening on the other side of the globe is no longer just a distant news story. It is the most realistic and urgent macroeconomic issue directly affecting your dollar exchange rates, U.S. stock holdings, physical gold prices, and bank deposit and lending rates.

Instead of complex and difficult financial jargon, we provide a precise analysis of what the “cracks in the petrodollar” mean at an eye-level tailored for retail investors, along with practical asset allocation strategies to safeguard your wealth.

1. What Is the “Petrodollar” System and Why Is It Causing Such a Stir?

For the past 50 years, any country in the world had to pay in U.S. dollars to buy crude oil. This is known as the “Petrodollar System.” Born out of an agreement between the United States and Saudi Arabia in the 1970s, this system has served as the strongest pillar maintaining America’s global financial and economic hegemony.

💡 Why Dollars Were Exclusively Used for Oil Trades and the Power It Created

• Creating Absolute Demand for Dollars: Oil is an essential commodity for all industries and national operations. Therefore, every country in the world had to continuously stack U.S. dollars in their central bank foreign exchange reserves to ensure uninterrupted oil imports. Through this process, the dollar became rooted as an irreplaceable “global base currency.”
• Virtuous Re-investment in U.S. Treasury Bonds: Middle Eastern oil-producing nations like Saudi Arabia and the UAE took the massive amounts of dollars earned from selling oil (petrodollars) and bought U.S. Treasury bonds (U.S. government debt) on a large scale. Thanks to this mechanism, the United States could print money almost limitlessly without suffering a sharp decline in the dollar’s value, comfortably maintaining its position as the world’s leading economic superpower.

⚠️ The Cracks Emerging Today (De-Dollarization)

Major countries in the BRICS+ (BRICS Plus) bloc—including China, Russia, Saudi Arabia, Iran, and the UAE—have officially declared: “We will now accept payment for oil in our own currencies (Yuan, Dirham, etc.) or Central Bank Digital Currencies (CBDC) instead of dollars!” When the dollar ceases to be a mandatory prerequisite for oil imports, global demand for dollar reserves shrinks, triggering a massive geopolitical shift where the structural value of the dollar declines.

2. Three Impacts of Weakening Dollar Hegemony on Your Account

As the global utility and demand for the dollar decrease, retail investors will directly experience the following market changes on the ground:

• Expanding Exchange Rate Volatility (Potential Long-Term Dollar Weakness): As essential global demand for the dollar declines, the value of the dollar may shift toward long-term weakness (falling USD exchange rates). Retail investors holding U.S. stocks or U.S. ETFs must calculate and prepare for currency loss risks (losses caused by a declining exchange rate), even if underlying stock prices rise.
• Rising U.S. Treasury Yields (Upward Pressure on Loan Interest Rates): If oil-producing nations no longer buy as many U.S. Treasuries with their oil revenues, the U.S. government must offer higher interest rates (yields) to sell its debt. Rising U.S. Treasury yields drive up benchmark interest rates across global financial markets, lowering stock market valuation multiples and adding upward pressure to domestic borrowing rates.
• Price Increases in Hard Assets (Gold and Commodities): When trust in paper currency diminishes, central banks and institutional investors worldwide begin stockpiling “real assets”—namely gold and raw materials—instead of paper money. In fact, central bank gold purchases globally have reached historical highs in recent years, serving as a powerful driver behind rising gold prices.

3. Top 3 Future Economic Scenarios at a Glance

Retail investors need to grasp macroeconomic trends in advance to take proper action and safeguard their portfolios.

Category	Key Situation & Operating Mechanism	Global Economic & Asset Market Fallout
📌 Scenario 1: Dual-Currency System (Dollar & BRICS) (Most Likely)	Raw materials like oil and minerals are settled in Yuan or oil-producer currencies, while high-tech IT products and Western services are settled in Dollars, solidifying a dual-currency era.	The uni-polar dollar hegemony unwinds, creating an environment where commodities and gold prices trend continuously upward.
💥 Scenario 2: Rapid Collapse of Dollar Hegemony & Inflation Spike (Severe Case)	U.S.-China conflicts reach an extreme point, leading oil-producing nations to reject dollar payments entirely. Dollars held overseas flood back into the U.S., causing runaway domestic inflation and severely shocking stock markets.	The purchasing power of cash assets collapses, leaving commodity-backed assets like gold, physical materials, and energy stocks with distinct defensive strength.
🌐 Scenario 3: Gradual Shift & Tactical Dollar Defense (Moderate Case)	The U.S. defends the dollar’s value using strong advanced technology (AI, energy independence) and military power, causing de-dollarization to proceed at a very slow, transitional pace.	Existing U.S. tech-heavy portfolios remain effective, providing ample time to gradually diversify assets.

4. Three Practical Asset Allocation Rules for Individual Investors

Here are three asset allocation strategies to protect your savings and generate returns amid de-dollarization and the weakening petrodollar.

• 1) Allocate 15% of Your Portfolio to Gold and Commodities: Historically, gold has proven to be the ultimate shield when paper currency values fluctuate. Maintaining around 15% of your total assets in physical gold markets, gold spot ETFs, or commodity funds significantly boosts your account’s resilience during dollar weakness or inflation spikes.

• 2) Keep U.S. Bond Exposure Light with Short-Term Bonds: During periods of high U.S. Treasury yield volatility, 10-year or 30-year long-term bonds carry substantial downside risk if interest rates rise. It is wiser to utilize short-term U.S. Treasury ETFs (with maturities under 1 year, such as SHV or BIL) to capture steady yield while minimizing duration risk.
• 3) Diversify into Global Logistics, Shipping, and Energy Stocks: As BRICS local-currency trade expands, trade transport routes diversify and grow more complex, keeping the value and freight rates of large crude oil tankers and global logistics companies elevated. It is beneficial to pay attention to and diversify into traditional energy (oil/gas) sectors and quality global shipping and logistics stocks.
