stock market news today: Crypto Market Faces Volatility After Fed Rate Cut

Crypto Market Overview: Key Movements and Data

As of September 19, 2025, stock market news today highlights significant volatility in the crypto sector. The total crypto market capitalization dropped by $63 billion in the last 24 hours, now standing at $3.98 trillion, according to TradingView. This decline follows a failed attempt to breach the $4.05 trillion resistance, signaling investor caution and potential weakness in broader market momentum. Major tokens such as Bitcoin (BTC), Ethereum (ETH), and Dogecoin (DOGE) have all experienced declines, with BTC currently trading at $115,846 after slipping from the $117,261 resistance level.

Altcoins have also faced notable losses. MYX Finance (MYX) dropped to $11.77, down over 35% from its weekly high. Worldcoin (WLD) fell to $1.5170, a 31% decrease from its year-to-date peak, while Pepe (PEPE) is down more than 15% from this week’s high. Meme coin Fartcoin (FARTCOIN) led the losses, plunging over 18% in the past 24 hours to $0.746. These movements reflect a broader trend of profit-taking after recent rallies, a common occurrence in both the stock and crypto markets.

Factors Driving Today’s Market Volatility

One of the primary drivers behind the current downturn, as reported in stock market news today, is profit-taking by investors. After strong gains earlier in the week—such as MYX Finance’s nearly 2,000% surge and Worldcoin’s 167% jump—many traders are locking in profits, leading to sharp corrections. This behavior is typical after significant rallies, especially in the highly volatile crypto sector.

Another major factor is the Federal Reserve’s recent decision to cut interest rates by 25 basis points. While such cuts are typically bullish for risk assets like cryptocurrencies, this move was widely anticipated and already priced in by market participants. As a result, the actual announcement triggered a “sell the news” reaction, with traders reducing positions amid uncertainty about future economic conditions. The Federal Reserve’s statement also hinted at more cuts in upcoming meetings, adding to the cautious sentiment.

Technical analysis further supports the bearish outlook. Bitcoin’s price chart shows a rising wedge and bearish divergence pattern, with the Relative Strength Index (RSI) forming a descending channel. These indicators suggest a potential for further downside, which could impact other altcoins if BTC fails to hold its $115,000 support level.

Wall Street’s Triple Witching and Its Impact on Crypto

Stock market news today also covers the quarterly “triple witching” event on Wall Street, where $4.9 trillion in stock and ETF options are set to expire. This event, occurring every March, June, September, and December, often leads to heightened volatility in both equities and crypto markets. Historical data shows that large-scale expiries can trigger sharp sell-offs and drawn-out consolidation periods, as seen in March and June 2025.

With leverage currently high among traders, the risk of margin calls and forced selling increases if volatility erupts. However, history also demonstrates that after such shakeouts, markets—especially Bitcoin—often rebound to new highs once excess leverage is cleared. The outcome of today’s expiry could therefore set the stage for the next significant move in both traditional and digital assets.

Sector Highlights: DeFi, RWAs, and Stablecoins

Despite the overall downturn, certain crypto sectors are positioned to benefit from the Federal Reserve’s liquidity injection. Decentralized finance (DeFi), real-world assets (RWAs), and stablecoins are attracting attention due to their sensitivity to fresh capital inflows. According to industry data, the total value locked (TVL) in RWAs has increased by 31% quarter-over-quarter, reaching $8.2 billion. Decentralized Physical Infrastructure Networks (DePINs) have also grown over 400% in 2024, with a collective market cap exceeding $37 billion as of September 2025.

Stablecoins, in particular, are expected to see increased demand as traditional yields compress. On-chain lending and structured products continue to offer attractive returns, making stablecoins a preferred vehicle for liquidity and transactions. This trend is likely to persist as rate cuts make conventional cash products less appealing.

Institutional Developments and Market Sentiment

Institutional activity remains robust, with BitGo filing an S-1 with the SEC to go public on the New York Stock Exchange under the ticker BTGO. This move aims to expand BitGo’s market presence and reflects growing institutional adoption of digital assets. Additionally, FTX is set to distribute $1.6 billion to creditors on September 30, which could potentially spark renewed interest in altcoins, though the payout is $300 million less than previously announced.

Meanwhile, Grayscale’s new CoinDesk Crypto 5 ETF began trading this week, offering exposure to BTC, ETH, XRP, SOL, and ADA. The fund’s portfolio is weighted 70% in BTC and 20% in Ether, targeting investors seeking a balanced approach to crypto exposure. The ETF has recorded a 40% growth this year and an 11% increase compared to Bitcoin since June, underscoring continued institutional interest in diversified crypto products.

Risk Factors and User Considerations

Stock market news today underscores the importance of risk management amid heightened volatility. The convergence of profit-taking, technical resistance, and macroeconomic uncertainty requires traders to exercise caution. While historical patterns suggest the potential for recovery after major shakeouts, the current environment is complicated by inflationary pressures, political uncertainty, and evolving regulatory landscapes.
