The first month of 2025 served as a stark reminder that cryptocurrency markets are no longer isolated digital experiments—they are now deeply interwoven with global macroeconomic forces. Bitcoin (BTC) and Ethereum (ETH) experienced pronounced weekend volatility, reacting sharply to geopolitical developments, monetary policy signals, and technological disruptions—often before traditional financial markets had even opened.
This shift underscores a growing trend: crypto is evolving into a leading indicator for broader market sentiment, particularly during off-hours when equities are closed. Understanding this new dynamic is essential for traders, investors, and analysts navigating an increasingly interconnected financial landscape.
Macro Forces Behind Crypto’s Weekend Whipsaws
January 2025 was defined by turbulence—not just in crypto, but across asset classes. The catalysts? A series of unpredictable macro developments centered around U.S. trade policy, central bank signaling, and emerging AI competition.

The sell-offs on January 13, 20, and 27 were not random. Each coincided with escalating uncertainty around Trump’s tariff announcements, which targeted key trading partners like Canada and Mexico. These policies introduced fears of inflationary pressure and global trade disruption—factors that weigh heavily on risk assets.
But crypto didn’t wait for Wall Street to open. Instead, BTC and ETH moved first—selling off in the early hours of Monday mornings (UTC), well ahead of European and U.S. equity markets. This early reaction suggests that crypto traders are increasingly acting as sentiment barometers, processing macro news faster than traditional investors.
Additionally, Federal Reserve Chair Jerome Powell’s hawkish tone from the December 2024 FOMC meeting—reinforced by strong labor data—fueled expectations of delayed rate cuts. This strengthened the U.S. dollar and pressured risk-on assets, with crypto absorbing the initial shock.
Another layer came from outside finance altogether: the release of DeepSeek, a competitive AI model that disrupted tech valuations. While not directly tied to blockchain, its impact rippled through equities—and by extension, crypto, due to their high correlation.
Crypto as a Leading Indicator: The Yen Carry Trade Precedent
This isn’t the first time crypto has foreshadowed macro moves. In August 2024, during the collapse of the yen carry trade, BTC sold off dramatically on a Sunday evening—before Japanese yen strength fully registered in global markets.
As cheap Japanese capital was unwound amid rising yields, risk assets suffered. Yet again, crypto reacted first, highlighting its role as a real-time gauge of global liquidity sentiment.
“When the tide turns, crypto often feels it first.”
Unlike traditional markets that close over weekends, crypto operates 24/7—making it uniquely positioned to absorb and reflect breaking news instantly. This continuous trading window allows it to act as a stress test for macro shocks, offering early signals about investor risk appetite.
Monday Morning Volatility: A New Market Pattern?
Recent weeks have revealed a consistent pattern: spikes in realized volatility late Sunday through early Monday (UTC). These aren’t just directional moves—they reflect heightened uncertainty and rapid price discovery during traditionally quiet periods.
Analysis of BTC’s 10-minute returns since November 2024 shows:
- Volatility peaks during U.S. and European trading hours (Monday–Friday).
- A sharp drop occurs over the weekend as institutional volume dries up.
- But crucially, there’s a recurring surge in volatility late Sunday into Monday morning.
This resurgence aligns with the opening of Asian trading sessions and the accumulation of weekend news flow. However, in January 2025, these spikes exceeded historical norms—reaching realized volatility levels near 150%, far above median ranges observed since mid-2023.

Even more telling is the behavior of implied volatility (IV) in options markets. Short-dated BTC options saw repeated inversions in their term structure—meaning near-term volatility expectations surpassed longer-dated ones—a classic sign of acute near-term fear.
These IV spikes persisted into Monday trading sessions, indicating that weekend events weren’t dismissed as noise but priced in as meaningful risk.
Ethereum’s Escalating Volatility Premium
While BTC absorbed macro shocks with resilience, Ethereum underperformed consistently during downturns in January. Each market dip saw ETH/BTC ratios decline, reinforcing ETH’s reputation as the more volatile major cryptocurrency.
Historically, ETH has exhibited higher realized volatility than BTC—especially since April 2024, following the post-spot ETF rally peak. But January 2025 marked an extreme divergence:
- Over the past 90 days, ETH’s realized volatility has been nearly 50% higher than BTC’s.
- Yet, options markets only price in a ~30% implied volatility premium for ETH.
This discrepancy suggests that ETH is moving more violently than traders expect—creating potential mispricing opportunities in derivatives markets.
The chart below illustrates this gap: while both realized and implied volatility ratios have trended upward, the former has outpaced the latter significantly.

Frequently Asked Questions
Q: Why do crypto markets react before traditional markets on weekends?
A: Cryptocurrencies trade 24/7, unlike equities which close over weekends. This allows crypto to process breaking news—such as geopolitical shifts or economic data—in real time, making it a leading indicator of market sentiment.
Q: Is Bitcoin becoming a macro asset?
A: Yes. Increasingly, BTC price action correlates with macro variables like interest rate expectations, currency strength, and risk appetite—similar to gold or tech stocks.
Q: Why is Ethereum more volatile than Bitcoin?
A: ETH’s ecosystem is more complex, with active development in DeFi, NFTs, and smart contracts. It also has a younger investor base and higher sensitivity to tech-sector trends.
Q: What does “realized volatility” mean?
A: It measures actual price movements over a given period. High realized volatility indicates large or frequent price swings.
Q: How can traders use implied vs. realized volatility differences?
A: When realized volatility exceeds implied volatility, options may be undervalued—offering opportunities for volatility-selling strategies or hedges.
Q: Could crypto become a benchmark for global risk sentiment?
A: Evidence suggests it already is. Its early reactions to events like the yen carry trade unwind and tariff announcements show it’s being used as a real-time barometer of financial stress.
Conclusion
January 2025 marked a turning point in how we understand cryptocurrency markets. No longer niche or insulated, BTC and ETH are now integrated into the global macro framework, reacting swiftly—and sometimes preemptively—to geopolitical shifts, monetary policy cues, and technological disruptions.
Weekend volatility is no longer an anomaly; it’s a feature of a market that never sleeps. With BTC acting as a canary in the coal mine and ETH amplifying swings through elevated volatility, traders must adapt to this new rhythm.
Understanding the interplay between realized and implied volatility, recognizing crypto’s role as a leading indicator, and monitoring macro triggers like trade policy and liquidity shifts will be critical in navigating what promises to be a dynamic year ahead.
As institutional participation grows and market efficiency improves, one thing is clear: crypto isn’t just reacting to the world anymore—it’s helping shape how we see it first.
