Understanding the Dollar Index
The dollar index measures the strength of the U.S. dollar against a basket of major global currencies, primarily the Euro, Japanese Yen, British Pound, Swiss Franc, Canadian Dollar, and Swedish Krona. Among these, the Euro has the largest weight. The index provides insights into how strong or weak the U.S. dollar is compared to other global currencies.
Why a Strong Dollar Hurts Risk Assets
When the dollar strengthens, it often attracts investment into U.S. markets and assets, which can negatively impact riskier assets such as gold, Bitcoin, and emerging markets. Conversely, a weak dollar tends to support these risk assets because when the dollar declines, investors often seek better returns in other options, like gold or foreign markets.
History of Dollar Down Cycles
Over the last 50 years, there have been two significant dollar down cycles. The first lasted from the mid-1980s to the mid-1990s, and the second occurred from the early 2000s to around 2011-2012. During both periods, gold and emerging markets experienced substantial rallies. As of 2024, the dollar index appears to be entering a third major down cycle.
Is a Breakdown Already Underway?
Recent chart patterns (see image below) indicate that the dollar index may be on the verge of breaking key support levels. If this trend continues, the index could fall to 90 or even 80. A drop of this magnitude would likely trigger a new bull run in emerging markets and commodities like gold.

Why Policymakers May Welcome a Weak Dollar
A weaker dollar can enhance the competitiveness of U.S. exports, which benefits the economy. Policymakers may prefer this scenario, especially when inflation is under control and the economy requires a boost. This supports the argument for a prolonged period of dollar weakness.
What This Means for Investors
If the dollar continues to weaken, global investors could benefit by increasing their exposure to gold, emerging markets, and other non-dollar assets. Historical cycles show that such periods often yield strong returns in these areas.
