Key Summary: On September 11, 2026, US August CPI rose 3.4% year-over-year, core CPI rose 0.3% month-over-month, higher than the 0.2% expected, and the 30-year Treasury yield hit a new high since 2004, yet Bitcoin rebounded above $79,000 on the same day. Data released the same day also showed that on September 10, US spot Bitcoin ETFs recorded net outflows of $282.6 million, the largest single-day outflow since July 13. In the short term, Bitcoin showed resilience to macro headwinds, but ETF outflows and rising rate hike expectations remain key risk variables to monitor.

Event Recap: CPI, Bond Yields, and Bitcoin's Intraday Performance
According to Cointelegraph on September 11, the US Bureau of Labor Statistics reported August CPI rose 3.4% year-over-year, while core CPI rose 0.3% month-over-month, higher than the expected 0.2%. The upside surprise was mainly driven by stickiness in services components such as housing and medical care, reigniting market concerns about the pace of disinflation.
On the same day, the 30-year US Treasury yield hit the highest level since June 2004 at one point, then fell back to 5.309%. Surging long-term rates often weigh on risk asset valuations, but Bitcoin rebounded above $79,000 that day, with a daily gain of more than 3%.
Earlier on September 4, CNBC reported that Bitcoin gained 4.6% for the week and hit a high of $82,272.31, the highest since May 11; Ethereum hit $2,545.62, and Solana hit around $105.70. This suggests that in the early stages of rising rates, Bitcoin may still be supported by liquidity expectations and spot buying, but sustainability remains to be seen.
$282.6 Million ETF Net Outflows: Why the Divergence in Fund Flows
According to Cointelegraph on September 11, US spot Bitcoin ETFs recorded $282.6 million in net outflows on September 10, the largest single-day outflow since July 13; cumulative net outflows over the first three days of the week reached $449 million.
The divergence between ETF outflows and the same-day Bitcoin price rebound suggests that short-term buying may have come from the spot market or other channels rather than through ETFs.
This site's independent judgment: A single-day ETF outflow should not be equated directly with a trend reversal; it requires analysis of multi-day fund flows, trading volume, and derivatives positioning. If ETFs continue to see large outflows over the next few trading days and the price fails to hold above $79,000, caution is warranted regarding weakening rebound momentum. However, if the price remains flat or rises despite outflows, it indicates strong spot demand. For related analysis, refer to OKX Radar's coverage of ETF outflows and the impact of rising Treasury yields.
Record-High 30-Year Treasury Yield and Rising Fed Rate Hike Expectations
The market's probability for a 25 basis point rate hike at the Fed's September 16 meeting rose from 60% a week earlier to 85%, according to FedWatch data cited by Cointelegraph on September 11. The 30-year yield hitting a 22-year high reflects concerns over long-term inflation and bond supply.
Rising rates increase the risk-free return and compress risk asset valuations, but Bitcoin has shown some independence in the short term. Independent researcher perspective: This independence may stem from the crypto market's response to "rate hike expectations already being fully priced in," or may be supported by other non-macro factors. Going forward, watch whether the Fed's actual decision, dot plot, and Powell's language align with current rate expectations. If the actual hike or guidance exceeds the 85% pricing, risk assets could face a second shock.
How Traders Should Watch This Type of Market: Operational Education and Data Verification
The following steps help readers avoid equating a single macro data point with a trading signal and build a repeatable verification process:
- Build a data calendar: Record key time points such as the Fed decision on September 16, October CPI release, and daily ETF fund flow updates. OKX Radar's Macro and Market columns can help track these time points.
- Cross-verify sources: CPI data should be based on the official website of the US Bureau of Labor Statistics; ETF fund flows on disclosures from issuers or professional data platforms; rate expectations on CME FedWatch. OKX Radar's reports label original sources for easy verification.
- Watch for divergence signals: When ETF fund flows diverge from price trends, check whether spot trading volume, large on-chain transfers, and derivatives open interest move in sync.
- Distinguish one-off shocks from trend changes: A single month of higher-than-expected CPI or a single-day ETF outflow is only a data point; data over three to five consecutive trading days is more informative.
- Record and review: Write down the price path and fund flow changes before and after each macro event in a trading journal to avoid emotional decision-making.

Why did Bitcoin rise after CPI came in higher than expected?

Is the record-high 30-year Treasury yield bullish or bearish for Bitcoin?
Traditionally, rising risk-free rates compress risk asset valuations, which is a bearish factor; however, Bitcoin still rose that day, showing some independence. Going forward, watch the Fed's actual decision and changes in rate expectations.
What impact will the increased probability of a Fed rate hike on September 16 to 85% have on Bitcoin?
