Bitcoin slips to US$83,400 as markets watch oil and US inflation

Bitcoin traded near US$83,400 on 30 September 2026, down about 0.7% over 24 hours, at around 6 p.m. Sydney time. Markets were watching oil prices and US inflation at the same time. Higher oil prices can make transport and business costs rise, and that can keep inflation—rising everyday prices—high. High inflation adds pressure on interest rates and on risky investments such as crypto. Money is still entering Bitcoin funds, however. US Bitcoin ETFs received US$66.2 million more than investors withdrew on September 29. ETFs let people invest in Bitcoin through the stock market. This supports demand, but selling by other investors can outweigh it. The next major test for the market is the US PCE inflation report, scheduled for 10:30 p.m. Sydney time tonight. It measures changes in consumer prices. Inflation that comes in above expectations could pressure crypto. A lower result than expected could help ease concerns about high interest rates.
