Bitcoin pulled back toward $78,000–$79,000 last week as rising Treasury yields and inflation concerns weighed on risk assets. The coming days will test whether this is a short reset or the start of a deeper decline.

ETF Flows Signal Caution

U.S. spot Bitcoin ETFs recorded $290.4 million in net outflows on May 15, according to Farside Investors. That came after a heavy $630.4 million outflow on May 13 and a brief $131.3 million inflow on May 14.

ETF flows have become one of the clearest signs of institutional demand. When outflows build, it adds pressure — especially when Bitcoin is already trading near key support levels.

Ethereum ETFs also saw outflows. Farside data showed $65.7 million leaving on May 15 and $36.3 million on May 13. That puts Ethereum fund demand below Bitcoin demand right now.

Solana was the exception. Its ETFs were flat on May 15, but the weekly total stayed positive after earlier inflows. Solana stands out as a key altcoin to watch if investors look for alternatives to Bitcoin.

The CLARITY Act Moves Forward

The U.S. Senate Banking Committee passed the CLARITY Act in a 15-9 vote on May 14. The bill aims to define when crypto tokens should be treated as securities or commodities, and it also addresses stablecoin rules.

Two Democrats voted in favor at committee level. But the bill still faces hurdles on the Senate floor, with concerns around anti-money laundering rules and potential conflicts of interest.

If the bill progresses, it could benefit Coinbase, stablecoin issuers, and tokens like XRP, Solana, and Ethereum. Delays or pushback could cool the optimism that followed the vote.

Bond Yields Are the Key Macro Threat

CoinCentral reported that two-year and 10-year Treasury yields hit 12-month highs last week. The 10-year yield moved above 4.55%, while the 30-year yield reached its highest level since 2007, according to Investing.com.

Higher yields make safer assets more attractive. That reduces appetite for risk assets like crypto.

Bitcoin was also trading below its 200-day moving average, which adds a technical concern on top of the macro pressure.

If yields ease, risk sentiment could improve quickly. If they keep rising, both Bitcoin and altcoins may struggle.

What to Watch for Altcoins

Solana, XRP, BNB, Dogecoin, and Chainlink could all see movement depending on where capital flows next. But altcoins typically need Bitcoin stability to hold their ground.

If Bitcoin continues to slide below $80,000, smaller tokens are likely to face sharper losses.

This week’s ETF data, any Senate updates on the CLARITY Act, and Treasury yield movements will be the key signals for where crypto heads next.
