比特币在81,000美元上方交易，监管进展与ETF需求重塑市场格局

周一，比特币价格在81,000美元上方波动，延续了对上周跌破76,000美元的复苏态势。监管环境的演变、交易所交易基金（ETF）需求的回升以及即将到来的美国宏观经济事件，共同构成了市场下一阶段测试的关键因素。

市场动态概览

在经历了上周剧烈波动的交易日后，比特币成功站稳81,000美元关口。现货比特币ETF在中周遭遇大规模撤资后，于周四和周五实现了5.925亿美元的净流入逆转。目前，比特币的相对强弱指数（RSI）仍处于超买区域之下，而MACD指标在反弹后继续显示积极的短期动能。本周，美国初季调采购经理人指数（PMI）数据及美联储官员的讲话将影响利率预期。此外，特朗普与习近平定于周四会面，投资者正密切关注双方在贸易、科技和关税方面的讨论。

Market data showed that during the Asian trading session on September 21, BTC rose less than 1% in the past 24 hours. As buyers returned over the weekend, prices recovered and remained above $80,000, after two trading days of heavy selling. The recovery began with the September 17 decision of the U.S. Securities and Exchange Commission (SEC) to open a regulatory channel for eligible tokenized U.S. stocks. Although the SEC's decision did not directly attribute any price increase in Bitcoin to the announcement, the exemption is consistent with improving overall sentiment on digital assets.

The SEC stated that eligible tokenized securities platforms can operate with temporary conditional exemptions while institutions consider long-term rules. This innovative exemption framework allows eligible platforms to trade certain tokenized national market system stocks through licensed automated market makers and liquidity pools during a five-year conditional exemption period. Token holders must enjoy the same legal and economic rights as traditional share owners. Issuers reserve the right to oppose tokenization of their securities by unrelated platforms, and smart contracts used by qualified platforms must remain publicly auditable.

Bitcoin's latest move follows this regulatory development, although price movements remain below the area where resistance was formed at around $82,000 over the weekend.

ETF demand picks up: rebound after $746 million divestment

上周，机构资金流动为比特币带来了又一次重大震荡。美国现货比特币ETF在9月14日记录了约1.599亿美元的净流入，但随后投资者在9月15日和16日分别撤资4.504亿美元和2.959亿美元。这两天合计撤资约7.463亿美元，恰逢比特币下跌至75,000美元中低位区间。

需求在周后半段回归。现货比特币ETF在9月17日吸引1.595亿美元流入，随后在9月18日加速至约4.33亿美元。费达（Fidelity）的FBTC在周五反弹中领涨，流入3.107亿美元，而贝莱德（BlackRock）的IBIT增加了1.084亿美元。在整个五个交易日中，这些基金最终录得约620万美元的净流入。与此同时，美国现货以太坊基金记录了约1.406亿美元的净流出。

资金流动的时机与比特币动荡的一周紧密追踪，尽管ETF的申购和赎回本身并不能确立个别价格变动的原因。

技术指标：动能积极但未进入超买区

比特币当前的技术指标显示出改善的动能，但未出现超买读数。14周期相对强弱指数（RSI）为59.96，高于其移动平均线57.35。RSI保持在70以下，这是识别超买条件的常用阈值。在从76,000美元下方反弹后，该读数将比特币置于中性偏多头领域。RSI保持在其移动平均线之上，表明反弹期间动能已增强。

MACD sends a similar signal. The MACD line is located around 193.33 and the signal line is approximately 143.26, producing a positive histogram close to 50.07. A positive MACD histogram suggests that short-term upward momentum remains intact, although BTC still faces resistance before significantly expanding its gains.

Currently, Bitcoin is approaching the resistance zone of US$81,700 -82,000, which saw selling pressure over the weekend. If it can continue to break through this region, the market will surpass its latest local rejection level. Conversely, if the psychological threshold of $80,000 falls below, the $79,000 region may come back into view, and a deeper reversal will put pressure on the recent breakthrough structure.

The Federal Reserve's speech and PMI data may drive this week's market

Monetary policy remains one of the main macro variables in Bitcoin. On September 16, the Federal Reserve raised its benchmark interest rate range by 25 basis points to 3.75%-4.00%. The Federal Open Market Committee (FOMC) unanimously approved the rate increase. In its policy statement, the Fed said economic activity continued to expand at a solid pace, while inflation remained high. Although there are no planned interest rate decisions this week, multiple Fed officials are expected to speak. Investors will be watching their comments closely to determine whether the September rate increase was an isolated event or part of a longer sequence of tightening.

Forecasts released by the Federal Reserve at its September meeting showed that policymakers still believe there is room for further interest rates in 2026, but future decisions depend on incoming economic data. An important data point will be released on Wednesday: S & P Global will release the initial September U.S. manufacturing, services and composite purchasing managers 'indices at 9:45 a.m. EDT on September 23. The initial report for August showed that the manufacturing industry was 53.9 and the service industry was 56.5, both higher than the 50 level that distinguishes expansion and contraction. Stronger September data could support expectations that the U.S. economy can tolerate tighter monetary policy; weaker readings could reignite the debate about how far the Fed can continue to raise interest rates.

Trump-Xi meeting adds market catalyst

On Thursday, the market focus will turn to U.S. -China relations, with President Donald Trump and President Xi Jinping scheduled to meet on the same day. According to reports, trade, tariffs, investment, export controls and technology restrictions are expected to be the focus of discussions. Markets will see whether the two sides extend the current trade truce or resume friction. Existing tariff arrangements expire in November, making Thursday's meeting relevant to stocks, currencies and other risky assets affected by changes in U.S. -China trade policy.

On the eve of the talks, it was reported that the RMB rose to its highest level against the U.S. dollar in more than three years, while the U.S. dollar index was trading around 100.23.
