On a chilly morning in lower Manhattan, the dollar’s decline began as a silent flicker on a Bloomberg terminal inside a glass-walled trading floor with a view of the Hudson River. Not a single alarm went off. No one shouted. Several traders, however, leaned forward simultaneously and narrowed their eyes as they perceived something familiar and unnerving happening in real time.
The U.S. dollar index had quickly dropped below levels it hadn’t seen in years, prompting comparisons to 1985, when world powers convened at the Plaza Hotel in New York to purposefully devalue the currency. That event became known as the Plaza Accord, and it continued to be remembered in the financial world for decades as a reminder that currencies, even those that are dominant, can be pushed, steered, and occasionally shaken.
Now that it’s happening, it feels both different and oddly similar.

When the dollar was strong in 2025, its dominance was almost frightening. Travelers bemoaned the high cost of their European vacations. The burden of debt denominated in dollars created difficulties for emerging markets. The trend then almost suddenly turned around. Early in 2026, the dollar had fallen to four-year lows and was losing ground to the pound, yen, and euro. It was not a slow transition. Investors were caught off guard because it felt abrupt.
Markets didn’t seem to be ready for how fast it was happening.
Interest rates are one factor in the explanation. The dollar is losing appeal as investors come to believe that the Fed will lower interest rates to help a faltering economy. The currency was being strengthened by higher interest rates drawing foreign capital into U.S. assets. That advantage seems to be eroding now. You can see the story developing without anyone having to say it aloud by keeping an eye on the bond market in recent weeks, where yields have been trending lower.
Policy ambiguity hasn’t been helpful.
Trade tensions, tariffs, and erratic political cues have complicated the dollar’s interpretation. Silently, some analysts contend that the weakness might not be wholly unintentional. A depreciating dollar boosts domestic industries by increasing the competitiveness of US exports. Whether this result is deliberate or just accepted is still unknown, but markets have started to modify their expectations in light of it.
In particular, currency traders in London and Tokyo have responded cautiously. They don’t exhibit overt panic. They speak in hushed tones, change allocations, and hedge instead. The distinction that may be most telling is that one trader in London recently characterized the atmosphere as “uneasy, not frightened.”
The role of the dollar is not limited to the US.
Global trade, commodity prices, and central bank reserves are all anchored by it. Widespread ripple effects occur when it abruptly weakens. The price of oil moves. Import prices increase. Pressures from inflation shift. Small businesses that import goods also experience it, though they rarely understand why.
The rates shown on digital boards appeared to startle passengers as they passed a currency exchange booth at Heathrow Airport last week. The dollar didn’t seem to be as powerful as it used to be. Most didn’t pause to consider it. There was a difference, though.
Additionally, there is a psychological component at play.
The strength of the dollar was regarded for decades as a permanent state. It was the foundation of investor strategies. States depended on it. Its supremacy turned into the norm. Now, as I watch it move in unexpected ways, I’m a little less sure of that permanence.
History makes interpretation more difficult.
By 1985, the dollar had grown too strong, hurting U.S. exports and prompting a concerted effort to devalue it. The situation now is more disjointed. International alliances are not as stable. Power in the economy is more distributed. Money movements would be much harder to coordinate now, and possibly much more brittle.
Nonetheless, investors appear to be able to spot trends.
The rising price of gold is frequently viewed as a hedge against the decline of the dollar. In order to diversify their reserves, some central banks are adding euros and other currencies. Though slow and almost cautious, these changes raise fundamental concerns about the future.
One can’t help but notice how silent it is.
The dollar is still in use. The news hasn’t made headlines outside of the financial industry. Rather, it has gradually and persistently slipped, changing presumed truths that seemed to be timeless.
Markets are still operational. The stock market fluctuates. Company operations are routine.
Confidence, however, feels a little less absolute than it used to be.
