Bitcoin and Ethereum prices surged after reports of a US dollar collapse spread across the market. The latest data shows the US dollar has fallen to a four-year low, raising concerns about the strength of the world’s dominant reserve currency. How the dollar is weakeningmarket participants are starting to pay attention to alternative assets such as precious metals and digital currencies, including BTC, which is increasingly seen as a potential security against rising inflation and currency depreciation.

The US dollar falls to a low not seen in 4 years

New reports from Bloomberg highlight the continued decline in the US Dollar Index (DXY) in recent weeks, with the price continuing to decline following President Donald Trump’s comments on the currency’s performance. Sources reveal that Trump said the dollar was “doing great” despite the ongoing economic downturn.

Traders interpreted the president’s seemingly lukewarm response to the falling dollar as a signal that the decline could continue, triggering further selling pressure. Data from the online stock research platform Finviz can be seen that at the time of writing the US dollar index collapsed to 95.92 from the previous level of around 100. This signs to the weakest level in almost four years, specifically from 2022.

Additionally, Bloomberg reported that its Dollar Spot Index also posted a four-day low since Trump announced modern tariffs in April 2025. Traders in the $9.5 trillion-a-day currency markets are also increasingly betting that the dollar could fall further as US policy risk burden the world’s main reserve currency.

Amid the decline in the US dollar index, cryptocurrencies such as Bitcoin and Ethereum are seeing gains. The price of BTC has increased above $89,000, while Ethereum rose over 3% to reach over $3,000 in the last 24 hours. This simultaneous rise in cryptocurrency prices along with a weakening U.S. dollar suggests that this may be the case for investors transfer of capital to risky assets.

Recently a “Master of Crypto” market analyst scratched several reasons for the continued decline of the weakening US dollar in a post on X. He explained that the huge budget deficitsThe Fed’s challenge of balancing inflation control with labor market stability, a steady supply of bonds and currency hedging actions is keeping the U.S. dollar near recent lows. According to him, in this type of market environment, holding free cash becomes a significant risk for investors.

Possible implications for the price of Bitcoin and Ethereum

Historically, periods of weakening of the US dollar have been common coincided with Bitcoin’s rallyand other cryptocurrencies. When the dollar declines, investors sometimes look for alternative assets to maintain value. This could raise demand for Bitcoin and Ethereum, which many are seeing alternative value carriers and risky assets.

While this correlation does not clearly indicate the cryptocurrency’s potential growth, analysts such as “Milk Road Macro” suggest that a falling dollar could facilitate support a broader recovery in the cryptocurrency market. He said that as the dollar weakens, capital will flow into precious metals such as gold and silver. Shortly thereafter is the same capital it is expected to change to BTCwhich may cause prices to rebound.
