BTC Jumps Back Over $91,000 With Buyers Defending the $80K–$85K Zone

Institutional momentum boosted crypto markets on Tuesday as industry heavyweights Vanguard and Bank of America took steps to broaden access to digital assets for their clients.

Bitcoin staged a strong rebound during U.S. morning trading, surging back above $90,000 and reversing much of its sharp decline from the weekend that briefly pushed prices under $84,000. The leading cryptocurrency was recently quoted around $91,180, up 8% over the past day and helping to lift the wider digital asset complex.

Ether also recovered, climbing past $3,000 with a 9% gain. Major altcoins followed suit: XRP, Solana’s SOL, and dogecoin advanced between 7% and 10%, bouncing off recent lows as sentiment improved across large-cap tokens.

Fueling the move was a major policy shift from $11 trillion asset manager Vanguard, which ended its long-running rejection of crypto and will now allow customers to invest in digital asset ETFs. Additionally, Bank of America approved guidance for its wealth managers to recommend a 1%–4% allocation to spot bitcoin ETFs, marking another milestone for institutional adoption.

Rising Japan bond yields could pressure crypto

Even as markets recovered, some analysts warned of potential headwinds. Mark Connors, founder and chief macro strategist at bitcoin advisory firm Risk Dimensions and former global head of risk advisory at Credit Suisse, cautioned that a rise in Japan’s 10-year government bond yield could redirect capital away from global markets. Crypto — and bitcoin in particular — may be especially vulnerable due to heavy leverage and close links to Asian liquidity flows.

He noted that Binance, which accounts for nearly half of global crypto trading volume and offers leverage up to 50x, could be sensitive to fluctuations in the yen and yuan. Connors also pointed out that bitcoin appears to be leading the S&P 500 lower, a dynamic he expects to continue until the Federal Reserve and Bank of Japan deliver their policy decisions later this month. If markets deteriorate sharply, he anticipates some form of intervention, consistent with recent precedent.

Still, not all market signals are bearish. Jasper De Maere, desk strategist at Wintermute, said derivatives activity reflects “a clear lean toward bullish, short-vol behaviour.” Traders have been selling downside puts around the $80,000–$85,000 zone while selectively accumulating longer-dated upside exposure.

According to De Maere, “the mix suggests the market sees $80,000–$85,000 as supported and is comfortable leaning long into year-end while earning carry along the way” — indicating traders are positioning for a potential rebound despite near-term uncertainty.
