As bitcoin appeared poised to break through the $80,000 threshold, macroeconomic uncertainty has resurfaced as a significant obstacle. A notable development emerged from a classified Pentagon briefing to U.S. lawmakers, which indicated that clearing mines in the Strait of Hormuz could take a minimum of six months and would only commence after the resolution of the U.S.-Iran conflict. Additionally, the briefing warned of potentially sustained high gasoline and oil prices through the midterm elections, as reported by the Washington Post.

Prolonged high energy costs may lead to persistent inflation, limiting the Federal Reserve's ability to reduce interest rates, which would create a challenging environment for risk assets. Given bitcoin's sensitivity to interest rates and global liquidity conditions, rather than real economic activity, rising costs for essential items like fuel and food could diminish investors' appetite for speculative assets. These risks are already manifesting in markets, with WTI crude prices increasing to around $95 from $79 late last week, and government bond yields rising across major economies. The U.S.

10-year yield has risen by eight basis points to 4.32% this week, while its U.K. counterpart has increased by 18 basis points to 4.96%. According to Michael Kramer, founder and CEO of Mott Capital Management, 'Oil prices are rising alongside yields and widening volatility spreads, signaling tighter financial conditions and increasing market risks.' Despite these challenges, U.S.-listed spot bitcoin ETFs continue to demonstrate sustained demand, with funds experiencing their fastest inflows in a month based on the seven-day moving average of net flows tracked by Glassnode.

However, some analysts are advising caution, suggesting that the rally lacks broad-based support in the spot market. Julio Moreno, head of research at CryptoQuant, noted, 'The recent Bitcoin price increase is completely driven by demand in the perpetual futures market.

Meanwhile, spot demand is still contracting, although at a slower pace.' The market capitalization of USDT, the largest dollar-pegged stablecoin, has reached a record high of $188.88 billion, while speculation in non-serious tokens is nearing a fever pitch, with overcrowding in bullish bets.
