On September 18, Solana (CRYPTO:SOL) opened at $101.52, soared to $114.34, and closed at $112.70, marking a notable 11% increase in the Solana price in just one day. In contrast, Bitcoin (CRYPTO:BTC) opened at $76,349, hit a high of $81,388, and closed at $80,875, gaining 5.9%.
While Solana appeared to outpace Bitcoin significantly, leading many traders to speculate about a rotation of capital into altcoins, it’s worth digging deeper into the session’s dynamics.
Two Rate Decisions and a Short Squeeze Lifted the Whole Crypto Market on September 18
The day’s trading followed critical rate announcements. The Federal Reserve had raised interest rates by 25 basis points on September 16, its first hike since 2023, which effectively priced in the expected outcome and allowed both Bitcoin and Solana to hold steady near their respective support levels. The narrative shifted when the Bank of Japan raised rates to 1.25% on the morning of September 18, weakening the yen and driving capital into dollar-denominated assets as U.S. Treasury yields fell.
Bitcoin initially spurred the market’s climb past $80,000, triggering the liquidation of about $170 million in short positions. Each liquidation forced exchanges to purchase back coins to close losing bets, creating a cascading effect that further propelled prices upward. This is why sharp breaks through psychological price points can look like fresh buying demand, even when it’s primarily short covering.
The positive momentum wasn’t isolated to Bitcoin; major altcoins followed suit, with Ethereum rising 6.8% from $2,445 to $2,611 and XRP appreciating about 7%. When key crypto assets move in sync because of the same catalysts, it suggests buying pressure is coming from the same group of investors.
Why the Solana Price Climbed Higher Than Bitcoin
Solana’s impressive rally that day was also fueled by a major development: the deployment of the third phase of the SIMD-0525 upgrade, which reduced its target slot time from 300 milliseconds to 250 milliseconds, improving network speed by about 17%. This upgrade positioned Solana to attract more user interest and market activity, further distinguishing it from Bitcoin on a day of bullish market sentiment.
Additionally, because Solana’s market cap is much smaller than Bitcoin’s, it is inherently more susceptible to larger price swings from the same volume of buy orders. As a result, the market-wide 5% rise could translate to an 11% jump for Solana without any direct capital moving out of Bitcoin.
However, signs of a market correction can appear quickly. Solana traded at $113.23 by the close on September 19, dipping to $110.70 shortly thereafter, indicating a pullback, while Bitcoin remained relatively stable around $81,200. Typically, the asset that experiences the sharpest gains under these conditions is the first to show weakness in subsequent trading days, making this behavior characteristic of a squeeze, not a rotation.
Bitcoin Gained 5.9% on the Same Day, Which Rules Out a Rotation
A true rotation, characterized by money flowing out of Bitcoin and into altcoins, would show Bitcoin remaining flat or losing ground while altcoins like Solana surged. Instead, on September 18, Bitcoin not only gained 5.9% but also demonstrated resilience in the following session, indicating simultaneous accumulation in both assets rather than an outflow of capital.
In the broader weekly context leading into September 19, Bitcoin rose 5.11%, while XRP lagged with a 3.45% gain. Despite Solana’s standout performance on September 18, its gains were largely realized in that single session, making it hard to claim a lasting rotation into altcoins.
Is the Rotation From Bitcoin Into Altcoins Starting?
In conclusion, the data suggests that no true rotation into altcoins has commenced. The activity on September 18 can be attributed to a generalized market rally, propelled by simultaneous central bank actions and a squeeze of short positions, with Solana’s additional gains rooted in specific network developments. Authentic rotation would require a pattern in which altcoins consistently outperform Bitcoin on days when it remains flat, which has yet to be observed.
