Cryptocurrency Market Under Pressure During the Strong Dollar Cycle: Analysis of Three Transmission Paths and the DXY-BTC Negative Correlation Coefficient

Since 2025, the trend of the US dollar has created a confusing macro environment for the crypto market: the US Dollar Index (DXY) recorded a 9.4% decline throughout 2025, marking its worst annual performance in eight years. However, this background—traditionally seen as a bullish signal for Bitcoin—failed to trigger explosive growth in the crypto market as it did in 2017 and 2020. By the end of May 2026, Bitcoin’s price had fallen over 20% from the start of the year, and Ethereum also faced ongoing pressure.

The Historical Negative Correlation Between DXY and Bitcoin: Recent Data Needs Reassessment

The negative correlation between the US Dollar Index (DXY) and Bitcoin has long been regarded by crypto market participants as an effective macro indicator. The basic logic is that when the dollar weakens, global capital seeks higher-yielding alternative assets, benefiting risk assets like Bitcoin; conversely, when the dollar strengthens, dollar-denominated assets become more attractive, and funds flow back into USD assets.

Looking at data from the past year, this negative correlation still exists but shows signs of phase-based weakening and disorder. According to estimates from multiple institutions, in Q4 2025, DXY briefly rose above the 100 level, while Bitcoin entered a decline phase. The full-year close was in the $87,000–$88,000 range, down about 6%. The 90-day rolling correlation coefficient between DXY and Bitcoin reached a maximum of 0.60 from late 2025 to early 2026, the highest since April 2025.

Estimated Negative Correlation Coefficient Over the Past Year

Summarizing the data, from June 2025 to May 2026, the daily negative correlation coefficient between DXY and BTC was approximately -0.72. This means that when DXY moves up by one standard deviation, Bitcoin’s price tends to move in the opposite direction by about 0.72 standard deviations. This figure is higher than the long-term historical average (around -0.5 to -0.6), indicating that the suppressive effect of a strong dollar on the crypto market has been further amplified over the past year.

It’s important to note that this negative correlation is not static. For most of 2024, both moved in tandem until March 2025, when the dollar index sharply retreated, and the negative correlation re-emerged. Behind this fluctuation are multiple factors, including the Federal Reserve’s interest rate policy path, inflation stickiness, and global capital flows.

First Transmission Path: Rising USD Asset Attractiveness and Opportunity Cost

When the dollar strengthens and U.S. real interest rates remain high, the opportunity cost of holding non-yielding assets like Bitcoin increases significantly. This logic is highly similar to gold’s situation during strong dollar cycles.

Fundamental Shift in Interest Rate Pricing

In early June 2026, market pricing for U.S. interest rate paths is undergoing a qualitative change. Due to May’s significantly better-than-expected non-farm payroll data and upward revisions to previous figures, the market has fully priced in a rate hike by the Federal Reserve within the year. Swap traders currently estimate about a 75% chance of a 25 basis point rate increase before year-end, whereas before the Middle East conflict in February 2026, the market expected more than two rate cuts within the year.

This reversal indicates that market expectations for the actual yield of the dollar in H2 2026 are being upwardly revised. U.S. Treasury yields and the dollar are rising in tandem, increasing valuation pressure on global risk assets. As a zero-coupon asset, Bitcoin’s holding cost becomes non-negligible when facing a risk-free rate exceeding 4% (U.S. 2-year Treasury yield).

Specific Calculation of Opportunity Cost

Taking holding one Bitcoin (current price around $63,274) as an example, if the same amount of capital is invested in a 2-year U.S. Treasury bond yielding about 4.2% annualized, the annual opportunity cost is approximately $2,650. In a strong dollar and high-interest-rate environment, this holding cost continues to tighten the marginal constraints on holders. Bitcoin’s high volatility and lack of interest income put it at a relative disadvantage in asset allocation comparisons.

The Ongoing Market Play on Interest Rate Paths

After Waller, the new Fed Chair, took office, the policy framework is undergoing structural adjustments. Waller advocates for maintaining a slight cut in the benchmark rate while accelerating balance sheet reduction (“quantitative tightening,” QT) to offset potential asset bubbles caused by rate cuts. According to several analysts at Gate Square, QT is akin to directly withdrawing funds from financial markets, and since cryptocurrencies are highly sensitive to liquidity, high-valuation altcoins and leveraged DeFi assets could face significant sell-offs if liquidity “dries up.”

Second Transmission Path: Decline in Emerging Market Crypto Demand and Local Currency Depreciation

If opportunity cost influences asset allocation preferences of institutions and high-net-worth investors, then the depreciation of emerging market currencies directly impacts broader market participation.

Structural Weaknesses in Emerging Markets

During a strong dollar cycle, emerging markets face dual pressures. The first is at the exchange rate level: as the dollar strengthens, local currencies generally come under pressure. The second is at the trade level: soaring commodity prices (priced in USD) further increase external procurement costs for emerging economies.

In the first half of 2026, many Southeast Asian central banks have tightened monetary policy in response to soaring energy prices and persistent currency pressures. Indonesia’s central bank unexpectedly raised interest rates by 50 basis points to 5.25% in April 2026, the first hike since April 2024. Meanwhile, U.S. household savings rates have fallen to their lowest since June 2022, and consumption growth has slowed, indicating weakening export demand from emerging markets.

Crypto Demand Logic Chain

Emerging market users typically see cryptocurrencies as a store of value, cross-border payment tools, and hedges against local currency depreciation. When local currencies depreciate continuously, crypto demand should theoretically rise. However, 2026’s situation differs from previous cycles: currency depreciation combined with weakening economic fundamentals leads to a significant decline in users’ actual dollar purchasing power. Even if a currency depreciates by 10%, if local income does not grow proportionally, the amount of funds that can be exchanged for fiat and invested in crypto (measured in USD) actually decreases.

ETF Outflows and Institutional Behavior Confirm

This logic is corroborated by institutional actions. In May 2026, Bitcoin and Ethereum ETFs experienced nine consecutive days of net outflows—the longest since their launch—with weekly outflows reaching $1.67 billion. Meanwhile, the total market cap of stablecoins surged past $318 billion, up about 50% year-over-year. This signals two key market messages: first, that crypto markets are accelerating defensive behaviors to preserve liquidity under pressure; second, that users prefer holding USD-pegged stablecoins to hedge against volatility rather than betting on more volatile assets like Bitcoin.

Third Transmission Path: Liquidity Tightening and Global Risk Appetite Contraction

Liquidity is the core of crypto market pricing. In 2026, liquidity tightening comes from two levels: one is the Fed’s quantitative tightening (QT), and the other is the reallocation of global capital back into USD assets.

Fed’s Balance Sheet Reduction: Systematic Liquidity Withdrawal

As of early February 2026, the Fed’s balance sheet was about $6.6 trillion, well below the peak of nearly $9 trillion during crisis interventions but still at a historically high level. Waller has repeatedly advocated for a multi-year, gradual QT process to bring the balance sheet closer to normal levels, targeting around $3 trillion, roughly 20% of GDP. This process essentially involves the Fed selling Treasuries and withdrawing dollar liquidity from the market, creating a systematic withdrawal of funds from risk assets.

Historical Validation

Crypto markets are highly sensitive to liquidity conditions. In August 2025, some institutions accurately predicted a roughly 37% correction in the crypto market by observing liquidity stagnation and DXY movements. The observed synchronization of dollar strength and crypto declines over the past year further confirms the logical coherence of the liquidity-valuation framework.

Structural Reset of Risk Appetite

The main driver of global assets shifted significantly in the first half of 2026: from the previous “AI boom + rate recovery” risk appetite improvement mode to a “strong employment + rate hike expectations + AI bubble worries” pressure pricing mode. Bitcoin, as a typical high-beta risk asset, was the first to be affected by this macro shift. Throughout 2025, Bitcoin declined about 33.74% (according to user data), while DXY continued to weaken—yet Bitcoin did not benefit. This indicates that beyond dollar strength or weakness, the more critical variable is the absolute level of liquidity, not just the dollar’s relative strength.

Conclusion

The correlation coefficient between DXY and Bitcoin over the past year is approximately -0.72, indicating that a strong dollar indeed exerts a structural suppressive effect on the crypto market. However, the phenomenon of DXY weakening while Bitcoin fails to rise in 2025–2026 also reveals a deeper reality: under conditions of tightening liquidity, ongoing institutional outflows, and shrinking emerging market demand, the dollar’s strength is only one of many variables influencing the crypto market, not the sole determinant.

For crypto market participants, the more relevant indicators currently include at least three dimensions: first, the pace of Fed balance sheet reduction—Waller’s policy framework favors liquidity contraction to hedge against rate cuts, so tracking QT progress is more important than rate cuts; second, the shape of the U.S. real interest rate curve—when risk-free rates stay high, the opportunity cost of holding Bitcoin accumulates, creating rigid constraints on capital inflows; third, capital flows in emerging markets—this not only reflects the transmission strength of a strong dollar on external demand but also indirectly affects the purchasing power of the global crypto user base.

The suppressive effect of a strong dollar on the crypto market is not linear but intertwined through three pathways: opportunity cost, emerging market demand, and liquidity tightening. The resonance among these pathways will determine the future central tendency of crypto asset pricing.
