The cryptocurrency market has long been a magnet for high-risk investors, but recent events—like the TerraUSD (UST) collapse that saw its value plummet by over 99%—have raised serious concerns about systemic risks to the broader financial world. As panic spreads and market volatility intensifies, one question looms large: Could crypto instability threaten the traditional financial system?
In this deep dive, we’ll unpack the scale of the crypto market, who drives its movements, and how a digital asset meltdown could ripple through global finance.

How Big Is the Cryptocurrency Market?
According to data from Coingecko, the total market capitalization of all cryptocurrencies peaked at an all-time high of $3 trillion** in November 2021, driven largely by Bitcoin’s surge past $68,000. By May 2025, that figure had dropped to approximately $1.51 trillion**, reflecting widespread market correction and investor caution.
Within this ecosystem, Bitcoin remains the dominant player with a market cap of nearly $600 billion**, followed by **Ethereum** at around **$285 billion. While these numbers are staggering in the context of digital assets, they pale in comparison to traditional financial markets.
For perspective:
- The U.S. stock market has a total market cap of roughly $49 trillion.
- The U.S. fixed income market stood at $52.9 trillion as of the end of 2024, according to the Securities Industry and Financial Markets Association (SIFMA).
This means that even at its peak, the crypto market represented less than 6% of the size of the U.S. equity market. While growing rapidly, its relative scale suggests limited direct impact—on the surface.
However, size isn’t the only factor. The speed of contagion, leverage levels, and interconnectedness with traditional finance are what truly matter when assessing risk.
Who Holds and Trades Cryptocurrencies?
Initially popularized by retail investors drawn to decentralized finance and digital ownership, the crypto space is no longer just a playground for tech-savvy individuals. Institutional participation has surged dramatically in recent years.
Coinbase, one of the largest cryptocurrency exchanges globally, reported that in Q4 2024, institutional and retail investors each held about 50% of assets on its platform. This parity marks a pivotal shift from earlier years when retail traders dominated trading volume.
More strikingly, institutional trading volume on Coinbase reached **$1.14 trillion** in 2024—nearly ten times higher than the $120 billion recorded the previous year. This surge signals growing confidence among hedge funds, asset managers, banks, and even public corporations entering the digital asset space.
Yet concentration remains a concern. A report by the National Bureau of Economic Research (NBER) revealed that just 10,000 addresses (representing individuals or entities) control approximately one-third of all Bitcoin in circulation. Even more concentrated: around 3 million BTC are held by only 1,000 investors.
Such centralization contradicts the original ethos of decentralization and raises red flags about market manipulation, liquidity crunches, and sudden sell-offs triggered by a few major players.

Could a Crypto Sell-Off Impact the Broader Financial System?
Despite its relatively small size compared to traditional markets, regulators are increasingly sounding alarms. The U.S. Treasury, the Federal Reserve, and the international Financial Stability Board (FSB) have all identified stablecoins as a potential threat to financial stability.
What Are Stablecoins—and Why Do They Matter?
Stablecoins are digital tokens designed to maintain a stable value by being pegged to traditional assets like the U.S. dollar or backed by reserves such as cash, treasury bills, or commercial paper. They serve as critical bridges between fiat currencies and volatile cryptocurrencies, facilitating trading and liquidity across platforms.
However, their stability is only as strong as the assets backing them—and the transparency surrounding those assets.
When confidence wavers, even briefly, it can trigger a cascade effect. Consider what happened with TerraUSD (UST) in May 2025:
- UST broke its 1:1 peg with the U.S. dollar, dropping to as low as $0.67 within days.
- To defend its value, the issuing entity began selling off reserve assets—including large holdings of Bitcoin—to buy back UST.
- This massive BTC dump contributed to Bitcoin’s price crashing below $28,546, dragging down other digital assets and eroding investor trust across exchanges.
The incident exposed a key vulnerability: a lack of clear regulation and disclosure around reserve holdings. Unlike banks subject to audits and capital requirements, many stablecoin issuers operate with minimal oversight. If a major stablecoin were to lose its peg due to asset devaluation or redemption runs, it could destabilize not just crypto markets—but also affect money market funds, short-term debt instruments, and banking liquidity if those reserves include significant amounts of commercial paper or government bonds.
Moreover, as more companies tie their balance sheets to crypto performance—whether through direct investments or blockchain-based revenue models—the spillover risk grows. Traditional financial institutions are also increasingly involved via custody services, futures trading, ETFs, and lending platforms.
This growing interdependence means that while crypto may still be a niche market in size, its potential to amplify shocks is real—and growing.

Frequently Asked Questions (FAQ)
Q: What caused Luna (TerraUSD) to crash so severely?
A: TerraUSD relied on an algorithmic mechanism rather than full cash reserves to maintain its dollar peg. When investor confidence collapsed during market stress, arbitrage mechanisms failed, leading to a death spiral where both UST and its sister token LUNA lost nearly all value.
Q: Are all stablecoins at risk of collapsing like TerraUSD?
A: Not all stablecoins use algorithmic models. Major ones like USDT (Tether) and USDC (Circle) claim to be backed by real-world assets such as cash and short-term securities. However, concerns remain about audit transparency and reserve quality—making regulatory oversight crucial.
Q: How are governments responding to crypto risks?
A: Regulators worldwide are pushing for stricter rules on stablecoin issuance, exchange transparency, and investor protection. The FSB has proposed global standards for stablecoin regulation to prevent systemic risks.
Q: Can a crypto crash trigger a global financial crisis?
A: Currently unlikely due to limited direct exposure. But if major banks or investment firms face significant losses from crypto-linked products—or if a large stablecoin fails—the ripple effects could strain liquidity and undermine confidence.
Q: Should individual investors avoid crypto entirely?
A: Not necessarily. For those who understand the risks, allocating a small portion of a diversified portfolio to crypto may offer growth potential. However, thorough research and risk management are essential.
Q: Is Bitcoin still considered “digital gold” despite volatility?
A: Many still view Bitcoin as a long-term store of value hedge against inflation. However, its price swings challenge this narrative during crises when it often behaves more like a risk asset than a safe haven.
Final Thoughts
The collapse of Luna and the plunge in TerraUSD was not an isolated event—it was a warning sign. While the cryptocurrency market remains smaller than traditional financial systems, its interconnectedness is deepening fast. From institutional adoption to stablecoin reliance and cross-market exposures, the channels for contagion are real.
Regulators are now on high alert, recognizing that unchecked innovation without proper safeguards could endanger financial stability. For investors, understanding who holds power in this space, how quickly sentiment can shift, and where systemic vulnerabilities lie is more important than ever.
As digital assets continue evolving, so must our frameworks for managing their risks—before the next crisis hits.
