8月19日至20日,加密衍生品市场出现一轮集中空头回补,累计爆仓规模超过30亿美元。这是2021年11月以来最集中的一次轧空行情,也让比特币和以太坊在短时间内快速拉升。

比特币一度从日内低点约64100美元升至72000美元上方,以太坊24小时涨幅约18%。从结构看,这轮波动并非由现货慢慢推高,而是由高杠杆空头被动平仓放大。

美国财政部调整回购规模

报道显示,首个触发点出现在8月19日。美国财政部宣布,将10年至20年期、20年至30年期名义票息国债的流动性支持回购操作上限,由每次20亿美元提高至40亿美元,执行时间为9月9日至11月4日。

这一操作并不等同于量化宽松,但会减少市场对长期久期资产的承接压力,并压低长端收益率。对风险资产而言,流动性条件改善往往会先体现在价格弹性更高的市场,随后传导至加密资产。

消息公布后,比特币在一小时内由约64100美元升至66800美元。价格快速上行后,空头保证金压力上升,第一轮强平随即出现,随后演变为连锁式买盘。

18小时内形成连锁平仓

在永续合约市场,空头仓位跌破维持保证金后,交易所会通过市价买入完成平仓。这会继续推高价格,并触发更多空头被动回补,形成典型的轧空循环。

报道称,这一过程持续了大约18小时才逐步稳定。全市场爆仓总额超过30亿美元,其中空头约27.7亿美元,占比约92%;多头爆仓约2.64亿美元。

  • 单小时空头平仓约12.9亿美元
  • 比特币空头爆仓约13.7亿美元
  • 以太坊空头爆仓约10.1亿美元

从交易平台分布看,Binance爆仓规模约5.18亿美元,Hyperliquid约5.13亿美元,Bybit约3.03亿美元,其余分散在 OKX、dYdX 等平台。

空头仓位此前已积累六周

这轮行情之所以放大,与此前持续数周的偏空仓位有关。7月以来,比特币永续合约未平仓量持续上升,资金费率则长期处于负值,说明市场中做空力量不断增加。

在主要平台上,空头持仓一度略高于多头。报道提到,Binance空头占未平仓量约51.64%,OKX约51.13%,Bybit约52.25%。市场普遍押注价格继续下行,导致仓位明显偏向一侧。

负资金费率也强化了这种交易。以8月18日 Binance 比特币永续合约为例,8小时资金费率约为负0.012%,并持续了约三周。对部分交易者而言,做空不仅是方向判断,也是一种可持续收取资金费的仓位策略。

当宏观消息推动价格突然上行后,这类以收益为主的空头往往更快离场,进一步加剧了平仓速度。

山寨币波动幅度更大

除比特币和以太坊外,Solana、XRP 和 Dogecoin 也受到明显冲击。报道显示,Solana 永续合约空头爆仓约1.87亿美元,XRP约1.42亿美元,Dogecoin约8900万美元。

这类资产的永续合约市场通常更薄,做市深度较弱,买卖价差也更宽。因此,在同等爆仓金额下,山寨币价格往往比比特币和以太坊出现更剧烈的瞬时波动。

此外,平台风控机制也在本轮行情中承压。Hyperliquid保险基金损失约4700万美元,规模由约3.8亿美元降至3.33亿美元。Binance则在爆仓高峰时段两次触发自动减仓机制,以覆盖对手方缺口。

整体来看,这轮上涨既有宏观流动性消息推动,也有仓位过度偏空后的技术性回补。若后续长端收益率重新企稳,且美国财政部的扩大回购安排未延续,当前这类宏观支撑可能减弱。

CFTC Innovation Advisory Committee's First Meeting: Crypto Assets and Predictive Market Rules Enter the "Technical Details" Phase
The U.S. Commodity Futures Trading Commission (CFTC) held its first meeting of the Innovation Advisory Committee on August 20 in Washington. The committee was restructured from the former Technical Advisory Committee and is tasked with providing recommendations to regulatory authorities on technical, legal, policy, and financial cross-cutting issues. Its members come from exchanges, clearinghouses, crypto companies, predictive markets, academia, and public interest organizations. The meeting itself does not automatically result in new regulations, nor does it equate to consensus among committee members, but it indicates that discussions on derivatives regulation in the United States are shifting from principle-based support for innovation to more actionable issues such as market structure, product boundaries, monitoring capabilities, and customer protection.

In July, Japan's CPI rose to 1.8% and a new base period for 2025 was established: To understand inflation, one cannot focus solely on one figure
On August 21, the Statistics Bureau of Japan's Ministry of Internal Affairs and Communications released consumer price data for July. Nationwide, excluding fresh food, the core CPI rose by 1.8% year-on-year, in line with the median expectations of market surveys, and continued to rebound from 1.6% in June. There is also an important change that is easily overlooked in this release: Japan has officially started using the CPI series with 2025 as the base period. The update of the base period will adjust the weights of goods and services and reset the index reference point to the new consumption structure. Therefore, the July data is not only an inflation reading but also a new starting point for observing changes in residents' spending patterns after the pandemic and the energy shock.
