美联储利率决议前，比特币偏离传统市场关联

在美联储今日公布利率决定之前，比特币的表现已脱离了以往的市场常规。近期与美元指数及美股同步波动的比特币，由于短期关联性显著减弱，正展现出更为独立的定价特征。

根据CoinMarketCap的数据，比特币与美元指数在15天及更短周期内的相关性已降至仅+0.08的水平。而过去30天的相关性则为-0.54。与此同时，比特币与美国股市的联动性也出现了类似下滑：其与标普500指数的相关性从0.75降至0.43，与纳斯达克指数的相关性从0.60降至0.30，与黄金的相关性也从0.69大幅回落至0.28。

比特币为何脱离美元与股票走势？

这一市场变化的背后，是近期加密货币领域特有因素权重的增加。特别是《CLARITY法案》在美国参议院的关键程序性投票中未能取得进展，促使投资者将注意力从美联储政策和宏观经济指标转向监管动态。

由于参议院投票未达到推动法案所需的60票，加密市场对更清晰监管框架的预期随之减弱，比特币对此直接做出了反应。这表明比特币已进入一个无法仅用宏观数据解释的定价阶段。换言之，数字资产市场的新闻流向目前可能已经超越了传统市场指标的影响。

为何比特币的对冲策略需要调整？

The decline in correlation has made some hedging methods based on Bitcoin's historical relationship with U.S. stocks less reliable. For example, during a period when Bitcoin typically fluctuates in the same direction as the S & P 500, investors can balance their Bitcoin positions by shorting the S & P 500 futures contracts. However, when Bitcoin no longer moves in line with stocks, such beta-based hedging strategies may not provide the protection expected. The CoinMarketCap research team has previously pointed out that the reliability of this once-effective method is declining in the current market environment.

So, as the Federal Reserve's decision approaches, Bitcoin's response may depend more than just on the interest rate itself. Post-CLARITY regulatory developments may have an impact on market sentiment before interest rate decisions.

What does the Federal Reserve's interest rate decision mean for Bitcoin?

The market has basically priced the Federal Reserve's 25 basis point rate hike expectations. Therefore, the real factor that may trigger market volatility may not be the rate hike itself, but the signal sent by Federal Reserve Chairman Kevin Warsh.

If the Fed does not raise interest rates beyond expectations or adopt a more hawkish tone in its statement, the US dollar index may fall back. With other conditions unchanged, a weaker US dollar environment will provide positive support for Bitcoin.

In addition, investors need to pay close attention to U.S. Treasury yields. Sharp fluctuations in yields could tighten financial conditions, triggering risk aversion again in the crypto market.

比特币会重新回归旧有的市场关联吗？

美联储的决议对比特币而言是一次压力测试。接下来的市场走势将揭示比特币是否会重新加强与美元和美股的强相关性，还是将继续受监管新闻影响，保持独立的定价行为。

FxPro首席市场分析员Alex Kuptsikevich表示，投资者不应仅聚焦于25个基点的加息幅度，而应关注美联储传递的政策信号。因为相较于已被市场消化的加息幅度，关于未来政策路径的信号可能对波动率产生更大影响。
