Altcoins show mixed gains ahead of the Federal Reserve’s September 17 interest rate decision, with BNB, Sui, Hyperliquid, and XRP outperforming as leveraged bets and ETF developments fuel market volatility.
Altcoins posted selective gains ahead of the U.S. Federal Reserve’s key interest rate decision, with BNB rising 2.5% in 24 hours, followed by Sui, Hyperliquid, and XRP at 2.2%, 1%, and 0.7%. Analysts noted these gains were driven by project-specific factors rather than the Fed’s upcoming rate cut. Hyperliquid and BNB benefited from treasury buying discussions, while XRP gained momentum from a newly approved spot ETF. Layer 1 assets continued to outperform meme coins, Layer 2s, and gaming tokens, while leveraged bets on altcoins surged, briefly overtaking Bitcoin’s open interest on September 13. Institutional inflows into Bitcoin ETFs reached $2.34 billion last week, pushing global holdings to new highs. FalconX also withdrew over 413,000 SOL from major exchanges, signaling potential accumulation by larger players.
