BTC 比特币重回8万美元上方，受油价波动与美债收益率反转推动
2026年9月18日，比特币涨幅超过6%，重新站稳8万美元关口，并在周五华尔街开盘时触及局部高点81,034美元。截至发稿，BTC交易价格约为81,847美元。这一涨势跟随了美国国债收益率的突然反转，而后者则是对全球石油市场新恐慌情绪的回应。
此次反弹令空头措手不及。根据CoinGlass数据，在四小时内，针对加密货币的空头清算金额高达约2.5亿美元，随着价格上涨，杠杆做空头寸被迫平仓。
石油供应担忧再度升温
直接触发因素是原油价格。美国WTI原油期货一度跌至每桶94.8美元，随后在亚洲交易时段急剧反弹，回升至接近98美元的水平。这种剧烈波动反映了自今年初美伊战争扰乱霍尔木兹海峡以来一直存在的供应问题。
国际能源署（IEA）在同日发布的一份报告中详细阐述了破坏程度。数据显示，8月份通过霍尔木兹海峡的石油流量为每天760万桶，较冲突爆发前的水平减少了1,310万桶。
此前，IEA已在3月份释放了4亿桶战略储备以弥补供应缺口。这一干预措施加上出口路线调整和需求疲软，曾短暂缓解了价格在4月达到峰值后的上涨压力。但该机构现在警告称，这种缓解可能难以持续。
IEA指出，如果海湾地区的供应持续受限且商业库存继续缩减，可能需要提高价格和削减需求来填补缺口。这一警告几乎立即在债券市场引发了对通胀的担忧。
美债收益率反转，带动比特币上行
当日，美国30年期国债收益率飙升至5.34%，增幅达90个基点。长期收益率上升通常表明投资者预期通胀将持续或财政压力加剧，而油价飙升直接助长了这一预期。
这并非孤立事件。近几周以来，多个国家的收益率都在攀升，迫使美国和日本的央行走向加息之路。随着这种压力的累积，比特币曾跌至9月低点附近的75,600美元，其走势更多是追踪债券市场的压力，而非与之背离。
在2026年，比特币与收益率之间的联系已成为一种显著模式。当通胀担忧推高收益率时，比特币往往随之走高，而非充当对冲工具，因为较高的收益率增加了持有无收益资产的机会成本。然而，周五的反弹暗示着某种不同：收益率上升是因为石油冲击重新激发了广泛的市场风险偏好和重新定价，而作为流动性风险资产交易的比特币，顺势而上。
下一个关键测试位在82,000美元
Technical analysts are paying close attention to the resistance levels ahead. Trader Rekt Capital described the current juncture as a "critical moment" for bulls and noted that Bitcoin must break the key level of $82,000.
Failure to break through could repeat the pattern of mid-May, when a similar rally stalled and reversed. A second rejection in the same technology area will weaken the possibility of a sustained recovery.
But there is a more constructive signal underlying price behavior. Bitcoin has regained its "True Market Mean", a benchmark for the average cost of holding a currency in the secondary market, which currently stands at approximately $76,660. On-chain analysis firm Glassnode said this suggests the market is back in bullish patterns, as historical prices above the total cost benchmark are generally consistent with stronger currency holder confidence.
Corporate treasury holders are another reference point. Their average buying cost is about $80,500, close to Friday's trading range. This distance is important because treasury buyers with paper losses have less incentive to sell, and if they continue to exceed their cost benchmarks, selling pressure from this group may be completely alleviated.
Future Outlook
Bitcoin's rebound is real, but its foundations remain fragile. The rise relies on oil markets to avoid another surge in prices caused by supply disruptions, and also depends on whether bond yields will resume climbing and put pressure on risky assets again.
The $82,000 level is currently the clearest signal in the short term. If an effective breakthrough is achieved, Bitcoin will return to the bullish technical structure that existed before the stagnation in May; if it is rejected, the risk of falling to the real market average or even lower will increase.
For now, Bitcoin's price trend is not so much a narrative of specific demand for cryptocurrencies as a reflection of the collision between global energy markets and government borrowing costs. Investors following BTC should pay attention to both Strait of Hormuz shipping data and 30-year bond yields.
