The fluctuations of the US Dollar Index far exceed the expected impact range. It not only determines the direction of cryptocurrency price movements but also has a profound constraining effect on stock and commodity markets.

A review of the market performance over the past three years makes this clear. Why have stocks and commodities maintained a strong upward momentum? One of the core reasons is that the US Dollar Index has been in a continuous downtrend. A depreciating dollar means that other dollar-denominated assets are relatively cheaper, providing investors with a natural hedging mechanism. But there is a detail worth noting — the reaction of stock and commodity markets to dollar fluctuations is not as sensitive as that of cryptocurrencies. Their volatility patterns are also more independent, although they follow macroeconomic cycles, they do not exhibit the obvious four-year periodicity like cryptocurrencies.

Where is the real turning point? It is when the US Dollar Index re-breaks through the key level of 100. Once this moment arrives, market positioning behavior will change significantly because it indicates that the dollar will start a new upward trend. For cryptocurrencies, this is undoubtedly a negative signal — when the dollar appreciates, dollar-denominated crypto assets will come under pressure. Meanwhile, the rally of traditional assets like gold and stocks may also slow down noticeably.

Don’t misunderstand — this doesn’t mean they will stop rising. Over a sufficiently long time horizon, these assets will continue to move upward. But the growth rate will be much more moderate, especially in 2025, if the US Dollar Index truly breaks through this resistance zone. The comparison chart between gold and the US Dollar Index reveals this — over the past three years, gold has shown a beautiful parabolic rally, while the dollar index has been deeply embedded in a macro downward trend. Looking back at the dollar appreciation cycle from 2021 to 2022, gold’s performance was quite weak.

How to strategize? From a long-term perspective, if the US Dollar Index successfully breaks through 100 and begins a new upward cycle, the correct approach should be to gradually reduce dollar exposure and shift to assets that can maintain performance in a dollar appreciation environment — whether cryptocurrencies, stocks, or commodities.

But here’s an interesting paradox. Although the dollar is relatively cheap now, many assets in the market are actually overvalued. In this environment, perhaps the most pragmatic choice is to accumulate cheap dollars. This is one of the reasons we managed to grasp the Bitcoin top in early October. Sometimes, the best investment decision is not to chase the hottest assets but to wait for the real buying opportunity in a dollar appreciation environment.
