Bitcoin (BTC) price exceeds $79000, inflation data comes out-What does CPI numbers mean for cryptocu

Key Highlights

Expectations for the Federal Reserve to raise interest rates are heating up, and exchange-traded fund (ETF) activity reveals a divergence trend. Bitcoin (BTC) prices broke the $79,000 mark as core annual inflation data fell to a 66-month low of 2.4%. However, the monthly reading of the core consumer price index (CPI) reached 0.3%, exceeding expectations of 0.2%, causing the probability of a Fed rate hike to climb to 85%. At the same time, Ethereum-related ETFs attracted $216 million in inflows, of which BlackRock's ETHA products monopolized $149 million. Technical analysts pointed out that if Bitcoin can firmly stand above $80,000, it may move further towards $82,000 and $84,000.

Analysis of Market Dynamics and Inflation Data

Bitcoin resumes its gains

The world's largest cryptocurrency by market value regained momentum on September 11, breaking the threshold of US$79,000 after the release of U.S. consumer price index (CPI) data, which is generally in line with market expectations. Previously, Bitcoin briefly fell back to $76,000, before buying interest resurfaced. As of press time, the trading price of Bitcoin was US$79,387.86, up 2.89% in 24 hours. The entire cryptocurrency sector rose by 2.36% overall, and the total market value rose to US$2.69 trillion.

Inflation Data Details

Core inflation, which excludes volatile food and energy components, slowed to 2.4% year-on-year, the lowest level in 66 months. This indicator is widely seen as a more reliable measure of persistent inflationary pressures. Market analyst Crypto Patel previously emphasized on Platform X (formerly Twitter) that if the monthly core CPI falls below 0.2%, it may lower the Federal Reserve's expectation of raising interest rates, thus pushing up Bitcoin prices. However, the actual published reading of 0.3% further complicated the situation.

The overall inflation rate remained stable at 3.4% annually. Energy costs contributed significantly to monthly growth, with gasoline prices rising 3.9% in August, accounting for more than one-third of the overall monthly increase. Affected by rising oil prices due to geopolitical tensions between the United States and Iran, the composite energy index rose 2.1% during this period.

Breaking news: CPI inflation was 3.4% in August, in line with market expectations of 3.4%.
Core CPI inflation fell to 2.4%, also in line with expectations of 2.4%.
Monthly CPI inflation rose 0.4%, the largest increase since May 2026.

Fed interest rate hike expectations intensify

Although annual data showed signs of cooling, monthly core inflation growth of 0.3% exceeded the market consensus of 0.2%. This jumped the implied probability of a Fed rate hike at the September 16 policy meeting to 85%, from 60% seven days earlier, according to data from the Chicago Mercantile Exchange Group's FedWatch Tool. This monthly acceleration is attributed to continued "super core" services inflation, a measure that excludes energy and housing costs. Federal Reserve policymakers Christopher Waller has previously said he would prefer to keep current rates unchanged if inflation shows "some signs of deflation."

The U.S. 30-year Treasury yield soared to levels not seen since June 2004, and then fell back to 5.309%. Well-known trading firm QCP Capital warned that high yields pose obstacles for Bitcoin, describing the current situation as "the most unfavorable combination for Bitcoin"-providing risk-free returns of up to 5% without accompanying economic expansion.

ETF fund flows show divergence

Bitcoin ETF encounters continuous outflows

According to SoValue tracking data, the Bitcoin Spot ETF recorded a net capital outflow of US$13.29 million on September 11, which was the fourth consecutive trading day with negative capital flows. Morgan Stanley's MSBT was the only exception, recording a net inflow of $3.76 million. Market observer Ted Pillows commented on Platform X that the day's price rise was not supported by strong spot market demand, while increased expectations of interest rate hikes exerted downward pressure. He pointed out that if Bitcoin can stabilize strongly above $80,000 at weekly settlement and is accompanied by considerable ETF inflows, it may rebound to $85,000, but current market dynamics suggest that a correction is more likely.

$BTC daily MACD continues to decline. Today's rise is not driven by strong spot demand, and the probability of a rate hike is also rising. If Bitcoin can close strong above $80,000 with good ETF traffic, it could rebound to $85,000. But judging from the current situation...

Ethereum ETF performed well

Ethereum-themed ETF presented a completely different narrative, attracting a net inflow of US$216 million. BlackRock's ETHA products dominate with a contribution of $149 million. Ethereum itself surged more than 8% during the trading session, hitting a seven-month high of $2,640.

Technical Analysis

From a technical perspective, Bitcoin's MACD indicator showed a bullish convergence pattern, with the histogram turning to positive 13.86, although the two MACD lines were still trading below the zero axis. The Relative Strength Index (RSI) is 54.98, placing BTC in the neutral zone. As the market awaited the Federal Reserve's September 16 policy announcement, total outflows from Bitcoin ETFs reached $13.29 million on September 11, continuing a four-day outflow pattern.
