Bitcoin responded to a slowdown in the United States’ August personal consumption expenditures (PCE) inflation data and briefly rose above $85,000 overnight, but the uptrend soon cooled.

Decrypto, a blockchain media outlet, reported on Sept. 30 local time that bitcoin climbed to $85,598.94 intraday before sliding back to around $83,600.

The direct trigger for the market reaction was the PCE data. August PCE rose 0.3 percent from the previous month and 3.4 percent from a year earlier, below market forecasts of 0.4 percent and 3.7 percent, respectively. Core PCE, which excludes food and energy, rose 0.2 percent on the month and 3.0 percent on the year, also below forecasts of 0.3 percent and 3.3 percent.

Market expectations for the path of U.S. benchmark interest rates in October also shifted. CME FedWatch reflected a 62 percent probability that the U.S. Federal Reserve would keep rates unchanged and a 37 percent probability of a 0.25 percentage point increase. A reduced chance of a rate hike supports appetite for risk assets.

Still, inflation worries have not been fully resolved. The 3.0 percent core inflation rate remains above the Fed’s 2 percent target. In fact, the 10-year U.S. Treasury yield rose to about 5.25 percent on Sept. 29, marking the highest level since 2002.

Bitcoin was relatively resilient compared with traditional financial markets. On the same day, the S&P 500 fell 0.2 percent, while the Dow Jones index fell 0.3 percent and the Nasdaq index fell 0.1 percent. Brent crude briefly rose above $100 a barrel on concerns about disruptions to logistics through the Strait of Hormuz as U.S.-Iran tensions persisted, before slipping to $96.16. The consumer confidence index hit a 12-year low, and August job openings were tallied at 7.08 million, below expectations.

The total market capitalisation of the broader crypto market rose 0.6 percent below $3 trillion, but bitcoin’s gain was limited. Bitcoin stayed within a range formed after a sharp rise in September and mostly traded between $82,600 and $85,600 on a weekly basis.

Fund flows were also mixed. Bitcoin surged to $87,354 on Sept. 21 after a large exchange-traded fund (ETF) inflow and a large short squeeze, but the strength of ETF inflows has since weakened. The pace has also slowed from an earlier weekly inflow of $2.4 billion. The market is taking a cautious stance toward another sharp rise.

On prediction market Myriad, the probability that bitcoin will surpass its previous all-time high of $126,199.63 before 2027 was reflected at 7 percent. By contrast, the probability of holding above $84,000 in the near term was estimated at 49 percent, and the probability of topping $86,000 by early next week was put at 21 percent. The trend is placing more weight on maintaining the short-term range than on setting a new long-term high.

Technical indicators also signalled that while the broader direction remains upward, confirmation of a short-term breakout is still lacking. The average directional index (ADX) was 41.9, indicating a strong trend zone. The 50-day exponential moving average was $77,809.88 and the 200-day exponential moving average was $74,423.93, with the short-term average above the long-term average. The relative strength index (RSI) was 63.4, not in overbought territory but still indicating a level where buying dominance is maintained.

The issue is the resistance line. Bitcoin rebounded immediately after the PCE release but was blocked again near $85,599. That price level overlaps with the upper bound that has capped gains over the past week.

The next point to watch is whether bitcoin can close above $85,599. Above that, a renewed break above $87,354 was presented as an additional confirmation zone. This rebound showed that a slowdown in inflation data alone was not enough, and that bond yields and renewed inflows must support the move for a strong trend extension to be possible.
