There's something profoundly ironic in the fact that, while US stock markets continue to break records, the currency that underpins that entire system is experiencing one of its worst years since 1973. This isn't a sudden, headline-grabbing collapse. It's something more subtle, more insidious: a slow erosion of confidence that, for those who can read between the lines, tells a story far bigger than any single economic data point.

The Year That Broke the Mould

2025 will go down in history as the year the US dollar recorded its worst half-year performance in over half a century. Between January and June, the Dollar Index (DXY) fell nearly 11%, a move equivalent to a small earthquake for a global reserve currency. At the end of December, as I write these lines, the index is trading around 98, far from the 110 it started the year and its lowest level since 2022.

But the numbers, impressive as they are, don't tell the whole story. What we're witnessing isn't simply another currency cycle. It's the emergence of structural cracks in a system that has supported the global financial architecture for eighty years. And the interesting thing is that this time, the alarm signal isn't coming from the usual gold permabears or alternative finance conspiracy theorists. It's coming from the same central banks that have been hoarding dollars as strategic reserves for decades.

Gold at $4,500: It's Not Speculation, It's Strategy

When gold broke through $4,500 per ounce on Christmas Eve 2025, marking a 71% gain since the beginning of the year (the best since 1979, the year of the energy crisis and double-digit inflation), many commentators called it a speculative bubble. This is an understandable interpretation, but, in my opinion, profoundly flawed.

The 2025 precious metals rally has one characteristic that sets it apart from any previous speculative movement: it is being driven not by Wall Street traders or hedge funds, but by central banks around the world. According to data from the World Gold Council, central banks purchased nearly 800 metric tons of gold in 2025 alone, bringing the total gold reserves of BRICS+ countries to over 6,000 metric tons.

Russia and China are leading this gold rush, with reserves of 2,336 and 2,298 tons, respectively, but the phenomenon is much broader. India follows with 880 tons, while Brazil resumed purchases in September 2025 after a four-year hiatus. Even countries traditionally aligned with the West, such as Poland, are accumulating gold at a rapid pace.

De-Dollarization: Reality or Propaganda?

Here we come to the heart of the matter. The term "de-dollarization" has become one of the most overused in contemporary financial jargon, sometimes misused by those who see every market turmoil as the imminent end of American hegemony. The reality, as always, is more nuanced.

The dollar remains the dominant currency in international trade: approximately 90% of global transactions still take place in the greenback, and its share of global foreign exchange reserves, though declining, still stands at around 57%. We are not facing a sudden collapse, but a gradual erosion that could take decades to fully manifest.

However, it would be a mistake to dismiss these movements as irrelevant. October 31, 2025, marked a symbolically significant moment: the BRICS countries launched the pilot project for "Unit," a digital settlement currency pegged 40% to gold and 60% to a basket of member countries' currencies. It is not a currency for everyday use, but a tool for settling large commercial transactions without using the dollar.

It's important to note that not all BRICS members are aligned on the ultimate goal. India, through its Foreign Minister S. Jaishankar, has made it clear that it does not intend to replace the dollar as the reserve currency: "The dollar as a reserve currency is a source of global economic stability, and right now we want more stability, not less." Brazil has also softened its stance following American pressure. De-dollarization, in essence, is proceeding at different speeds and with objectives that do not always coincide.

The Debt Problem: The Elephant in the Room

If we wanted to pinpoint the root cause of the dollar's structural weakness, we shouldn't look to the BRICS summits or the maneuvers of Asian central banks. We should look to Washington, where US public debt reached $38 trillion in October 2025, while the fiscal deficit for the year just ended stood at $1.8 trillion.

To put these numbers into perspective: US public debt now stands at 98% of GDP, close to the all-time high of 106% reached immediately after World War II. Debt interest payments will exceed $970 billion in fiscal year 2025, becoming the third largest expenditure in the federal budget after Social Security and Medicare, and surpassing defense spending for the first time.

It's no coincidence that Google searches for the term "dollar debasement" reached an all-time high in the last quarter of 2025. Investors, even those less inclined to doomsayers, are starting to ask uncomfortable questions about the long-term sustainability of a system based on the continuous expansion of debt.

Implications for Investors

So let's get to the point that most interests those reading these pages: what does all this mean for those who invest in American stocks?

The first consideration concerns the currency effect. For a European investor, the 9.7% decline in the dollar in 2025 meant that the S&P 500 returns (although robust, around 17-18%) were partially eroded by the conversion to euros. This is a topic we often overlook when looking at the performance of US markets.

The second consideration is more structural. If the dollar is indeed entering a phase of prolonged weakness, as suggested by leading analysts like Morgan Stanley (which forecasts a further 10% decline by the end of 2026), the implications for portfolio allocation are significant. Historically, periods of dollar weakness have coincided with an outperformance of non-US equity and commodity markets.

Probabilistic Scenarios for 2026-2027

Based on the current dynamics, we can outline some scenarios with their relative probabilities:

There's also a more conservative scenario (20-25% probability) in which a geopolitical de-escalation and a rebound in US growth would restore confidence in the dollar, with gold potentially retracing towards $3,500-$4,000. Finally, there's a tail scenario (5-10% probability) with a sovereign debt crisis and a flight to safe-haven assets, which could push gold towards $7,000-$10,000.

Final Considerations

The dollar's "silent crisis" isn't the monetary apocalypse some prophets of doom have been predicting for decades. But it's also not a phenomenon to be dismissed with a shrug. What we're witnessing is a tectonic rebalancing of the global financial system, a process that will take years to fully unfold but is already producing tangible effects.

For the astute investor, this means several things. First and foremost, it means not taking the dollar's supremacy for granted and considering more careful currency diversification. It means evaluating exposure to precious metals not as a speculative gamble but as a structural hedge. And, perhaps above all, it means maintaining a long-term perspective that takes into account the major geopolitical forces at work.

Gold and silver didn't rise in 2025 because speculators expected higher prices. They rose because rational institutional actors—the central banks of countries representing nearly half the world's population—decided that the risk of confiscation of dollar assets through sanctions outweighs the opportunity cost of holding assets that don't pay returns. This is a strategic decision, not a gamble. And strategic decisions, once made, are unlikely to be reversed in the short term.

The world is changing, and with it the rules of the money game. It's up to us investors to adapt.
