September 8 Market Snapshot: Bitcoin and Ethereum Opening Prices and Two Rate-Hike Probability Timestamps
What are the specific prices and declines for Bitcoin and Ethereum today?
According to a Yahoo Finance report on September 8, 2026, Bitcoin opened at $79,093.85 on Tuesday, down 1.6% from Monday's open; Ethereum opened at $2,489.84, down 1%. This data is based on public market quotes, and prices may fluctuate in real time during trading.
Which dates do the two data points for the Fed rate-hike probability come from?
There are two timing references for the rate-hike probability. CNBC reported on August 31 that after Fed Chair Kevin Warsh's Jackson Hole speech, CME FedWatch showed the probability of a hike at the September 15-16 meeting rose to 66.1%. Meanwhile, a Yahoo Finance report on September 8 showed the market expected a 60% probability of a Fed rate hike the following week. The two statistics are measured at different points in time and should not be conflated.
How the Rate-Hike Probability Evolved from 66.1% to 60%: Divergent Stances of Warsh and Bessent
What did Kevin Warsh say at Jackson Hole?
CNBC reported on August 31 that after Fed Chair Kevin Warsh's speech at Jackson Hole, the market-implied probability of a rate hike at the September 15-16 meeting rose to 66.1%. This probability reflects pricing in interest-rate futures markets, not an official Fed decision.
Why is Treasury Secretary Bessent cautious about raising rates amid a supply shock?
US Treasury Secretary Scott Bessent said the economy is facing a supply shock, and traditionally the Fed would not raise rates during a supply shock unless second- or third-order effects emerge. The remarks, from CNBC's August 31 report, indicate policy-level disagreement over rate hikes. The market expectation fell back to 60% on September 8; the specific reasons were not detailed in public reports and need further verification.
Breaking Down PCE Inflation: What Headline 3.7%, Core 3.3%, and Trimmed Mean 2.3% Indicate
Why do headline PCE and core PCE differ?
The July PCE data cited by CNBC on August 31 showed headline inflation of 3.7% and core inflation of 3.3%. Headline PCE includes energy and food prices, while core PCE excludes these two components, so headline is higher than core, reflecting the impact of short-term shocks such as oil prices.
How does the Dallas Fed trimmed mean of 2.3% affect the rate-hike judgment?
The same report also mentioned that the Dallas Fed trimmed mean inflation rate was 2.3%. The trimmed mean excludes extreme volatility and can more stably reflect inflation trends. This measure is significantly lower than headline and core PCE, suggesting underlying inflationary pressure may be weaker than surface data indicate, adding complexity to rate-hike decisions.
Oil Near $100 and the US-Iran Conflict: How Supply Shocks Transmit to Bitcoin and the Rate-Hike Path
How does the US-Iran conflict drive oil prices?
Yahoo Finance reported on September 8 that oil prices were near $100 per barrel amid the ongoing US-Iran conflict, and the market expected a 60% probability of a Fed rate hike the following week. A supply shock may push up import prices, intensify inflationary pressure, and force the Fed to balance curbing inflation against supporting growth.
Is the supply shock a direct headwind for crypto markets or an indirect effect?
In an environment of shrinking risk appetite, Bitcoin and Ethereum are under pressure, but crypto assets do not have a strictly linear relationship with oil prices. This article does not provide unverified correlation inferences; investors should focus on the combined impact of macro data and market sentiment.
Strategy's Return to Buying for One Week: Can Institutional Buying Offset Macro Headwinds?
How long did Strategy's return to buying last?
Decrypt reported on September 8, 2026 that Strategy's return to buying Bitcoin lasted exactly one week. This single institutional action does not represent the overall market direction or predict future buying.
Do institutional purchases provide direct support for short-term prices?
The interplay between institutional behavior and macro liquidity tightening is uncertain. Against the backdrop of rising rate-hike expectations, whether a single institution's buying can offset macro headwinds lacks public data support, so no definitive conclusion should be drawn.

FAQ
What is the actual probability of a Fed rate hike in September? Which is accurate, 66.1% or 60%? ▼
Both are accurate, but they reflect different measurement dates. The 66.1% figure comes from CNBC's August 31 report, based on CME FedWatch data after Warsh's speech; the 60% figure comes from Yahoo Finance's September 8 report and reflects that day's market expectation. Pay attention to data release times and compare the latest values.

According to Yahoo Finance's September 8, 2026 report, Bitcoin opened at $79,093.85, down 1.6% from Monday's open; Ethereum opened at $2,489.84, down 1%.
What do headline PCE inflation of 3.7% and core PCE of 3.3% mean for crypto markets? ▼
Headline PCE is higher than core, reflecting rising energy and food prices, which may strengthen rate-hike expectations and thus pressure risk assets. However, the Dallas Fed trimmed mean is only 2.3%, indicating limited underlying inflation pressure, so the policy path remains uncertain.

Rising oil prices may intensify inflation pressure and raise the probability of rate hikes, creating pressure on risk assets. But crypto markets do not have a linear relationship with oil prices; the specific impact depends on macro sentiment and capital flows.
