How Geopolitical Events Shape Highest Value Currency: USD

Have you ever wondered why currency values can suddenly plummet or soar, leaving traders either thrilled or panicked? While many factors contribute to the ever-changing landscape of the Forex market, one crucial element often overlooked is the impact of geopolitical events. From elections to wars and everything in between, these occurrences can dramatically sway currency values, affecting your trading strategy and returns.

In the ever-volatile landscape of global economics, currencies rise and fall influenced by myriad factors. Yet, few currencies have enjoyed as much prominence as the U.S. Dollar. The question arises: what keeps the U.S. Dollar at the helm, and what are the potential implications for other currencies and the global financial system?

The Genesis: The Bretton Woods Agreement

To comprehend the prominence of the U.S. Dollar, we must first turn the clock back to the post-World War II era, specifically to the Bretton Woods Agreement signed in 1944. Named after the location in New Hampshire where the conference took place, this was a pivotal moment that marked the dollar's ascendance on the global stage.

King dollar

War-torn Europe was reeling from the devastation inflicted by the conflict, with major economies in shambles. The United States emerged as the new economic powerhouse, having avoided the brunt of the war's destruction on its own soil. It was therefore a natural decision to anchor the global financial system to the stability of the U.S. economy. Under Bretton Woods, major world currencies were pegged to the dollar at a fixed exchange rate, and the dollar was, in turn, pegged to gold.

The Dollar as the Global Reserve Currency

Over time, this anchoring to the dollar evolved into a system where nations began to hoard dollars as part of their foreign exchange reserves. These reserves provided countries with the liquidity required to engage in international trade and secure loans. This position was further solidified when the dollar became the primary currency for denominating commodities like oil in the international market, often referred to as 'petrodollars.'

Dissolution of Bretton Woods and the Dollar's Resilience

The next significant milestone came in the early 1970s, when the Bretton Woods system was dissolved, mostly due to the financial pressures faced by the U.S. due to the Vietnam War and other fiscal challenges.

President Richard Nixon announced that the dollar would no longer be convertible into gold, effectively taking the global financial system off the gold standard. This led to the era of fiat currencies, where the value of a currency is not backed by a physical commodity but is determined by supply and demand dynamics in the forex market.

Gold Dollar split

Despite this seismic change, the dollar did not lose its allure. In fact, it further consolidated its position as the world's leading reserve currency.

Why? Trust. The U.S. was still seen as an economic juggernaut with robust institutions and governance, making the dollar a safe bet in uncertain times.

Globalization and the Dollar

Fast-forward to the age of globalisation; the dollar became more than just a currency. It transformed into a tool for wielding economic and political influence. Countries that fell foul of U.S. policies found themselves facing economic sanctions, hampering their ability to trade because of the dollar's dominance in global transactions.

International organisations, trade contracts, and even aid often prefer or mandate transactions in dollars, increasing its ubiquity and indispensability in the global economic framework.

Financial crises have repeatedly rocked the global economic landscape, creating ripple effects that have led to job losses, recessions, and systemic failures. But amidst this turbulent financial backdrop, one constant seems to persist: the role of the U.S. dollar.

The dollar has been a key player in a multitude of financial upheavals, taking on different avatars across various crises.

Dollar & Financial crisis

This part aims to dissect the multifaceted role of the U.S. dollar in financial crises, with a particular focus on events like the 1997 Asian financial crisis, the 2008 global meltdown, the Gulf War, Brexit, and the post-pandemic economic scenario.

Dollars and the Financing of the Gulf War

The Gulf War was primarily a conflict initiated by Iraq's invasion of Kuwait, and it prompted a swift international response led by the United States. According to estimates from the U.S. Department of Defence, the war's financial burden on the U.S. was approximately $61 billion.

To fund this venture, the United States relied heavily on its own coffers but also received significant contributions from its allies. The monetary transactions and aid that flowed during this time were overwhelmingly in U.S. dollars, reinforcing the currency's global utility.

Oil Transactions and the Petrodollar System

A significant aspect of the Gulf War's economic impact was the relationship between oil and the U.S. dollar, often referred to as the "petrodollar" system. Oil transactions are usually conducted in U.S. dollars due to historical arrangements made with key oil-producing nations. This setup ensures that the demand for the dollar remains high, providing the U.S. with various economic advantages.

During the Gulf War, the importance of oil—and by extension, the U.S. dollar—was magnified. Control over oil reserves was one of the key strategic aspects of the conflict, and the fluctuations in oil prices had a rippling effect on global economies.

The Dollar as a Reserve Currency: Extensive Borrowing and Global Influence

The Gulf War required substantial financial resources, and much of this came in the form of extensive borrowing, primarily dollar-denominated debt. Countries involved in the conflict, directly or indirectly, found themselves tied to the U.S. dollar for financing their military commitments, humanitarian aid, or economic support packages. This further solidified the U.S. dollar's role as the world's de facto reserve currency.

Not only did the dollar's pivotal role in the conflict underscore its importance, but it also showed its utility as a tool of diplomacy. For instance, the U.S. was able to leverage its economic might to garner support or impose sanctions effectively. This dynamic became especially evident in its relationships with allies and neutral nations, as transactions often necessitated a reliance on dollar-denominated assets or transactions.

The 1997 Asian Financial Crisis

The 1997 Asian Financial Crisis remains one of the most significant events in modern economic history, particularly when it comes to understanding the complexities of currency roles in financial crises.

Several Southeast Asian economies found themselves embroiled in a turmoil that had devastating consequences not just for the region but also for the global economy.

The U.S. dollar was at the heart of this crisis, both as a catalyst and as an obstacle to recovery. This article aims to delve deeper into the role of the U.S. dollar during the crisis, exploring its complexities and influence over economies tethered to it.

The Rise of the 'Tiger Economies' and Dollar Pegging

To set the context, it's important to acknowledge that during the early and mid-1990s, countries like Thailand, Indonesia, and Malaysia were enjoying impressive economic growth, earning them the title of 'Tiger Economies.' Part of their strategy was to peg their currencies to the U.S. dollar to maintain stable exchange rates and attract foreign investments.

Tiger economies

This policy encouraged them to take on significant amounts of dollar-denominated debt, making them vulnerable to the dollar's fluctuations.

The Onset of the Crisis: Weak Local Currencies and Dollar-Denominated Debt

Everything seemed manageable until the local currencies began to weaken against the dollar. Thailand's baht was among the first to show signs of vulnerability, followed by Indonesia's rupiah and Malaysia's ringgit.

As these currencies started to devalue, the dollar-denominated debt burden increased in real terms, creating a vicious cycle that was hard to break. The weakening local currencies made it difficult for these countries to service their debts, which were becoming increasingly expensive.

The Dollar's Dual Role: Catalyst and Obstacle

In the midst of the crisis, the U.S. dollar found itself playing a dual role. On the one hand, the very strength of the dollar that had initially attracted these nations became a liability. It exacerbated the economic difficulties these countries were facing by increasing the burden of their dollar-denominated debts. On the other hand, the dollar also dominated all conversations around crisis management and recovery efforts. Any bailout packages, mostly orchestrated by institutions like the International Monetary Fund (IMF), were also denominated in U.S. dollars.

The Global Implications of the Highest Value Currency

The Global Financial Crisis of 2008

Fast forward to 2008, and the role of the dollar takes a dramatic shift. Unlike the Asian financial crisis where the dollar was seen as the problem, in 2008, it emerged as the solution. As the subprime mortgage crisis unfolded in the United States, economies around the world began to wobble. Investors worldwide flocked to the U.S. dollar, treating it as a 'safe haven' asset. Its value remained relatively stable, even as other currencies nose-dived.

The contrast in the dollar's role between 1997 and 2008 could not be more striking, illustrating its complex and ever-changing relationship with global financial stability.

Brexit: A Blow to the Pound, a Boost for the Dollar

In the financial ecosystem, Brexit presented another milestone. When the United Kingdom voted to leave the European Union in 2016, the pound took a beating. The dollar, however, enjoyed a surge as investors sought a more stable asset. While Brexit was primarily a political event, its economic repercussions underlined the dollar's role as a currency that could maintain its value amidst geopolitical uncertainties.

The Post-Pandemic Economy: An Era of Reckoning

As the world grapples with the economic aftermath of the COVID-19 pandemic, the dollar again finds itself in a unique position. On one hand, massive stimulus packages have led to fears of inflation, potentially diluting the dollar's value. On the other hand, its relative stability during these tumultuous times reinforces its image as a 'safe haven,' especially when compared to emerging market currencies that have been severely impacted.

China and the Dollar

In recent times, China has been aggressively pushing the use of its currency, the Renminbi, in international trade.

However, the dollar's deeply entrenched role, backed by decades of stability and the sheer size of the U.S. economy, has been a formidable obstacle for any currency attempting to challenge its supremacy. The Renminbi has gained some ground, but regulatory restrictions and lack of transparency in the Chinese financial system remain significant hurdles.

The Current State of the U.S. Dollar

Fast forward to the present day, and the U.S. Dollar continues to be the cornerstone of global finance. It's the currency that nations stockpile in their reserves, oil prices are denominated in it, and international contracts often demand it. However, this ubiquity comes with its challenges for both the United States and the global economy.

In 2022, the dollar reached parity with the euro for the first time in two decades, meaning one dollar was equal to one euro. Although this status didn't last long—since the dollar weakened again later in 2022—the event was a watershed moment. It underscored the ever-changing dynamics of global finance and brought into focus the impact of relative currency values, as described by Rob Haworth, senior investment strategy director at U.S. Bank.

Currency values are tied to a myriad of factors, including the interest rate environment, capital flows, and economic outlook. For example, the Federal Reserve's decisions in early 2022 led to higher bond yields in the U.S. compared to Europe. These higher yields attracted foreign investment, strengthening the dollar. However, shifts in central bank policies in both regions led to a reversal in the dollar's strength by mid-2023.

The trajectory of the dollar's value has consequences for the U.S. economy, affecting everything from the cost of imported goods to the revenues of multinational corporations. For instance, a stronger dollar makes U.S. exports more expensive, potentially reducing overseas sales for U.S. companies. On the flip side, a stronger dollar can lower the cost of imported goods for U.S. consumers. However, shifts in currency value can be highly unpredictable and should not be the sole determinant in investment strategies, as cautioned by Rob Haworth.

Investment Implications of Dollar Trends

Understanding the effect of currency trends on investments is crucial, particularly for diversified portfolios that include overseas assets. Currency fluctuations can either enhance or detract from investment returns when converted back to the investor's home currency. In 2022, for instance, the strong dollar negatively impacted the net return for U.S.-based investors in the MSCI European Union Index. The net return, translated back into dollars, resulted in a larger loss compared to the index's local currency terms.

While it's important to be aware of how currency trends may influence investment returns, they should not dictate "buy-and-sell" decisions entirely. Numerous factors contribute to stock performance, and it's essential to keep an eye on a broad range of indicators, not just currency trends.

The U.S. Dollar's preeminent position as the world's reserve currency brings forth a series of intricacies and paradoxes that are often underestimated or overlooked. While its dominant role offers certain advantages, such as liquidity and stability, it also exposes the global economy to a set of unique challenges. According to Michael Pettis, a prominent Professor of Finance at Peking University, a dominant U.S. Dollar might not actually be a win-win situation for all parties involved — including the United States itself. Let's delve deeper into the specific issues identified by Pettis and others in the financial community.

The Global Trade Dilemma

The first challenge we encounter is how the dollar's dominance affects global trade. Global transactions, whether they're for crude oil, machinery, or even services, are predominantly invoiced in U.S. Dollars. While this standardisation offers some conveniences, such as reduced transaction costs, it also poses problems.

  1. Loss of Competitive Advantage: Countries with weaker currencies generally have the opportunity to boost their exports, making their goods and services cheaper for foreign buyers. However, when trade is primarily conducted in U.S. Dollars, this advantage is effectively neutralised. Countries need to acquire dollars to participate in global trade, and that often means sacrificing the competitiveness of their own currencies.

  2. Dependence on Dollar Reserves: To facilitate international trade, countries are compelled to hold vast amounts of dollar reserves. This often leads to a state where nations must tailor their economic policies to ensure they accumulate enough dollars, sometimes at the expense of their domestic economic goals.

Currency Manipulation and Market Stability

Another challenge highlighted by Pettis is the potential for currency manipulation strategies. With the dollar serving as the cornerstone of the global financial system, it becomes a target for manipulation both by countries holding large reserves and by speculative traders.

  1. Impact on U.S. Exports: Countries with large dollar reserves can use their holdings to manipulate currency values subtly. By doing so, they can make U.S. goods more expensive and less competitive in the global market, thereby affecting the U.S.'s export potential.

  2. Potential for Financial Instability: Sophisticated currency manipulation strategies can have far-reaching implications, not just for trade but also for the stability of financial markets. For example, if a country decides to unload a large amount of U.S. Dollar reserves suddenly, it could trigger a sharp depreciation in the dollar's value, leading to market instability.

The U.S. Conundrum

Interestingly, while the dollar's dominance provides the United States with low borrowing costs and makes U.S. government bonds a popular global investment, it also shackles the country in some respects. The dollar's value and, by extension, the U.S. economy become increasingly sensitive to economic events and policy decisions happening outside of the United States.

  1. Lack of Policy Autonomy: As the issuer of the world's primary reserve currency, the U.S. Federal Reserve must consider the global implications of its monetary policies, limiting its options in addressing purely domestic economic issues.

  2. Economic Vulnerability: The sheer volume of dollars held in reserves worldwide means that actions taken by other countries can have a direct impact on the U.S. economy, making it susceptible to external shocks.

The Power of Geopolitical Events

The U.S. dollar isn't just a financial instrument; it's also a tool in geopolitical power plays. Economic sanctions, trade deals, and international diplomacy often hinge on the dollar's influence. For instance, the U.S. leveraged its currency's power to impose sanctions on Iran, impacting not only Iran's economy but also affecting global oil prices. Such geopolitical events can sway the confidence in the U.S. dollar, impacting its value.

Case Studies: The Good, The Bad, and The Ugly

Let's delve into two contrasting examples. In 2008, the subprime mortgage crisis led to a loss of confidence in financial markets. But paradoxically, investors flocked to the U.S. dollar as a 'safe haven,' showcasing the complex psychology that drives currency value. On the flip side, the Latin American debt crisis of the 1980s illustrated the disastrous impact that dollar-denominated debt could have on emerging economies.

The Gradual Shift of Influence

While it's unlikely the dollar will be ousted from its throne soon, other currencies like the euro and the renminbi are gaining prominence. C. Fred Bergsten argues that such diversification could be beneficial for global financial stability. These changes are often slow but could be accelerated by geopolitical tensions, like the growing trade rivalry between the U.S. and China or the imposition of sanctions.

Why is De-dollarisation Gaining Traction?

The use of financial sanctions, particularly against Russia and Iran, has triggered some countries to consider alternatives to the dollar. For instance, Russia has significantly increased its transactions in euros and the Chinese yuan in recent years. The 2022 Russian invasion of Ukraine, which led to unprecedented U.S. sanctions against Russia, has further accelerated this trend. Even U.S. allies like India have explored ways to bypass the dollar in trading with Russia.

Moreover, emerging technologies like blockchain and cryptocurrencies are providing new avenues for international transactions that could be less dependent on traditional financial systems and thus less susceptible to sanctions. This creates a real incentive for countries to develop a financial ecosystem that doesn't rely solely on the U.S. dollar.

The Contenders: Euro, Renminbi, and Digital Currencies

  1. The Euro: Despite its flaws—such as the absence of a common treasury and a unified European bond market—the euro remains the second most popular reserve currency. The European Central Bank's recent efforts to consolidate fiscal policies among EU nations could further strengthen the euro's role.

  2. Chinese Renminbi: The inclusion of the yuan in the IMF’s basket of reserve currencies in 2016 was a milestone for China. But several hurdles remain, such as restrictions on capital flows and a lack of transparency in its financial markets, which hinder the renminbi from becoming a dominant force.

  3. Digital Currencies: The rise of cryptocurrencies like Bitcoin and the introduction of state-backed digital currencies pose an entirely new challenge. While they offer a decentralised option and mitigate the risk of sanctions, their volatile nature and regulatory challenges make them a less-than-perfect substitute for now.

The Implications for Global Trade

So, what does this shift towards de-dollarisation mean for global trade? On one hand, moving away from a single reserve currency can reduce vulnerabilities and allow countries greater financial autonomy. On the other hand, a transition away from the dollar could lead to periods of instability as new systems are put in place.

For businesses and investors, a diversifying financial landscape means a more complicated calculus for risk assessment. The growing importance of understanding local currency dynamics and hedging against currency risks is essential in navigating these uncharted waters.

Can the Dollar Maintain its Reign?

The U.S. dollar's reign is far from over, but its unassailable position is indeed being questioned. The process of de-dollarisation will likely be slow and filled with obstacles. However, with a changing geopolitical landscape and advances in financial technology, it's a subject that must be closely monitored.

In sum, while the U.S. dollar is unlikely to be dethroned as the world's highest value currency anytime soon, the winds of change are blowing. Investors, policymakers, and financial market participants must stay alert to these developments to make informed decisions.

The Meteoric Ascent of Cryptocurrencies:

Let's take a recent step back and understand what cryptocurrencies are. Essentially, cryptocurrencies are digital or virtual currencies that use cryptography for security, making it difficult to counterfeit. Unlike traditional fiat currencies issued by governments—like the British Pound, the Euro, or the U.S. Dollar—cryptocurrencies operate on technology called blockchain, a distributed ledger that is maintained across multiple computers. This not only decentralises the currency but also renders it immune to governmental control and interference.

Why the Sudden Rise?

The concept of digital currencies isn't particularly new; however, the meteoric rise of cryptocurrencies can be attributed to several key factors. Firstly, the quest for financial autonomy has been a driving force. With cryptocurrencies, there is no need for a central bank or financial institution to oversee transactions. This feature appeals to those who prefer a system where their money isn't subject to government control or inflation.

Secondly, the promise of lower transaction costs has been an enticing factor. Traditional banking systems and online money transfers usually involve fees and exchange costs. Cryptocurrencies may minimise these costs significantly, offering a more cost-effective way to transact business.

Shaking Up the Global Equation

Cryptocurrencies also introduce an intriguing variable in the geopolitics of currency value and global influence. In a world where economic might often equals geopolitical power, the decentralised nature of cryptocurrencies provides smaller nations with a potential avenue to bypass traditional systems and make a direct impact on the global stage. Countries troubled with sanctions, for instance, have considered cryptocurrencies as an alternative route for international trade.

Challenges and Limitations

However, it's crucial to note that the cryptocurrency world is not without its fair share of challenges and limitations. Regulatory uncertainties, potential for misuse, and the volatility of cryptocurrency markets are all pertinent issues. These hurdles have led some to question the sustainability of these digital assets as a long-term replacement for traditional fiat currencies.

The Future Outlook

Nevertheless, as the technology continues to mature and regulatory frameworks are put in place, the potential for cryptocurrencies to serve as a viable alternative—or even a complement—to traditional fiat systems can't be ruled out. While we're not there yet, the steep ascent of digital assets has sparked a significant conversation about what the future of global finance could look like.

The Quest for a BRICS Common Currency:

A Strategic Pivot or a Pipe Dream?

In a recent BRICS summit held in Johannesburg, August 2023, Brazil's President Luiz Inacio Lula da Silva called for a transformative shift in the financial architecture of the five-member block. The proposal: creating a common currency for trade and investment between Brazil, Russia, India, China, and South Africa. While such a revolutionary idea carries a weight of potential benefits, it also presents a plethora of challenges, given the complex landscape of economic, political, and geographical divergences among these countries.

Why Does Lula Want a BRICS Currency?

The crux of President Lula's proposition lies in the desire to mitigate vulnerabilities arising from dollar exchange rate fluctuations. In his vision, a BRICS common currency could act as a financial stabilizer, providing a layer of protection against the global volatility often orchestrated by dollar-centric geopolitics. Lula argues that countries not dealing in dollars shouldn't be bound to trade in it. The same sentiment extends to his advocacy for a common currency in the Mercosur bloc, strengthening economic ties among South American nations. "Increasing our payment options reduces our vulnerabilities," he stated during the summit's opening plenary session.

What Do Other BRICS Leaders Think?

However, the sentiment does not appear to be universally shared among BRICS members. South African officials clarified that a common currency was not on the summit's agenda. Similarly, Indian authorities have dismissed the idea outright. On the other hand, Russia's President Vladimir Putin mentioned the possibility of transitioning trade among member nations from the dollar to their respective national currencies. China remained conspicuously silent on this issue, with President Xi Jinping focusing his remarks on the reform of the international financial and monetary system.

Challenges in Creating a BRICS Currency

As South African central bank governor Lesetja Kganyago rightly pointed out, a BRICS currency wouldn't merely be an economic undertaking but a "political project." The challenges are multifaceted. To begin with, such a currency would require a banking union, a fiscal union, and macroeconomic convergence. Not to mention the question of a disciplining mechanism for countries falling out of line with these strictures. Another obstacle is the location of a common central bank—where would it be headquartered?

Furthermore, trade imbalances within the bloc present a significant hurdle. As Herbert Poenisch, a senior fellow at Zhejiang University, notes, "All BRICS member countries have China as their main trading partner and little trade with each other."

Is the U.S. Dollar's Hegemony Waning?

Brics Currency

The proposal of a takes place against the backdrop of the U.S. dollar's diminishing share in official FX reserves. BRICS leaders have expressed a desire to lessen their reliance on the dollar, especially following its sharp strengthening last year. While the greenback's role in global trade remains dominant, accounting for almost 90% of forex transactions, the trend of 'de-dollarisation' is slowly gaining momentum.

The Stakes of Losing Dollar Dominance

But what if the dollar loses its dominant status? As experts like Liu warn, this could spell severe repercussions. The ethical and governance frameworks that guide global finance, largely U.S.-centric, could undergo a dramatic transformation.


The subject of the U.S. dollar's future influence is as complex as it is fascinating, involving a tangle of economic mechanisms, geopolitical strategies, and ethical considerations. A world where the dollar is less dominant may bring more balance, but it also introduces new kinds of risks and uncertainties.
