Warren Buffett, the renowned investor and chairman of Berkshire Hathaway, disclosed in a recent CNBC interview that his company acquired approximately $17 billion in U.S. Treasury bills during the latest government auction. This significant move into short-term government debt, coupled with Berkshire’s record-high cash pile, prompts a critical question for investors: is the Oracle of Omaha signaling an impending stock market downturn, and what might that mean for Bitcoin (BTC)?
Key takeaways:
-
Berkshire’s cash and cash equivalents stood at a staggering $373 billion at the close of 2025, more than double the amount held at the end of 2023.
-
Historically, Buffett’s strategic buildup of massive cash reserves has often preceded major U.S. stock market corrections, a dynamic that could pose a challenge for risk assets like Bitcoin.

Buffett’s Preference for Cash Signals Cautious Stance
Buffett’s commentary was clear: Berkshire Hathaway does not view the recent, modest pullback in U.S. equities as a compelling buying opportunity. The S&P 500 has declined roughly 5.75% since its all-time high in late January 2025. Buffett characterized this dip as insignificant when compared to historical bear markets, where indices have fallen by 50% or more. He stated stocks are not “substantially” cheaper.

This perspective explains Berkshire’s continued aggressive accumulation of Treasury bills. The company’s cash war chest has ballooned from $334.2 billion at the end of 2024 to $373 billion at the close of 2025, and is more than double the level from the end of 2023. This trend of building a fortress-like balance sheet is a well-documented precursor to Buffett deploying capital during market crises.
A Historical Pattern of Building Cash Before Crashes
Buffett’s disciplined approach to capital preservation is legendary. Analysis of his past moves shows a consistent pattern of raising cash ahead of major market downturns. For example, in 1998, as technology stocks began to look overvalued, Buffett started reducing Berkshire’s equity exposure. By mid-2000, just as the Dot-com bubble was peaking, the company’s cash and equivalents had grown to nearly $15 billion, representing about 25% of total assets. He then began investing that capital aggressively at rock-bottom prices after the bubble burst.

Bitcoin’s Stock-Like Behavior Creates a Vulnerability
For much of the period following 2020, Bitcoin has traded with a distinctly risk-asset profile, often moving in tandem with U.S. equities—particularly the technology-heavy Nasdaq Composite. This reduces its appeal as a non-correlated hedge during traditional market stress.
As of this week, the 20-week rolling correlation coefficient between Bitcoin and the Nasdaq remains positive at 0.47, indicating a moderate but meaningful positive relationship.

If Buffett’s current defensive posture is a correct read on upcoming market conditions, Bitcoin could face downward pressure alongside equities. This risk is compounded by a confluence of macroeconomic factors, including concerns over quantum-computing threats to cryptographic security, inflation pressures from geopolitical conflicts, and economic models suggesting nearly a 50% probability of a U.S. recession within the next year.
Furthermore, Berkshire’s recent portfolio adjustments reflect a broader skepticism toward the crypto-finance ecosystem. In Q1 2025, the firm completely exited its position in Nu Holdings, a fintech bank with crypto-friendly services, after holding it since 2021-2022. The exit generated approximately $250 million in profit but signals a strategic withdrawal from that sector.
It is important to note that some market analysts, citing the current macroeconomic headwinds and Bitcoin’s correlation profile, have forecast potential price declines to as low as $30,000 in 2026.
