Bitcoin is extending its late-September pullback as rising oil prices, higher Treasury yields and renewed geopolitical uncertainty weigh on risk assets. BTC was trading around $83,000 on Tuesday after opening the week at $84,454, briefly reaching $84,971 before falling to $82,579 and closing near $82,930, a daily dip of about 1.79%.
The immediate trigger was President Donald Trump's rejection of an Iranian proposal to reopen the Strait of Hormuz and resume peace talks within seven days. The response pushed prices for Brent crude higher than $100 a barrel and added to pressure on bonds. On Tuesday, the 30-year Treasury yield reached 5.61%, its highest level since 2002, while the 10-year yield approached 5.2%.
The combination puts downward pressure on Bitcoin. Higher yields increase the return available from traditional fixed-income assets, while a stronger Dollar can tighten financial conditions globally. Bitcoin depends heavily on liquidity and investors' willingness to carry risk.
The latest decline still leaves the broader Bitcoin rally intact. Figures from CoinGecko show BTC jumped from around $75,000 to above $80,000 in early September, reaching about $87,352 before settling into a period of consolidation. On a quarterly basis, BTC was up more than 40% through late September, putting it on course for its strongest quarter since late 2024.
The technical picture has weakened at the margin, though it hasn't yet signaled a break in the broader trend.
Bitcoin's 50-day moving average is still outpacing the 200-day average, forming a so-called golden cross that emerged after September's surge. The Relative Strength Index, or RSI, sits around 59, comfortably above neutral territory without approaching the 70 level commonly associated with overbought conditions.
The Average Directional Index, which measures the strength of a trend rather than its direction, is around 43. Those indicators suggest the market is still carrying upward momentum. However, Bitcoin can remain technically constructive while falling sharply when liquidity conditions change.
The Iran conflict has become an increasingly important part of Bitcoin's macro backdrop.
Iranian Foreign Minister Abbas Araghchi presented a seven-day plan at the United Nations aimed at reopening the Strait of Hormuz and restoring normal maritime passage. Trump rejected the proposal, while subsequent reporting indicated that indirect negotiations between the two sides could continue through mediators.
Markets remain focused on the Strait because of its importance to global energy supplies. Brent crude settled at $105.26 a barrel on Monday after initially rising more than $4. Oil prices subsequently eased as Saudi and other Gulf exports recovered, though flows remain below pre-conflict levels.
The effect on Bitcoin runs through inflation and interest rates as much as through geopolitical risk. Higher energy prices can keep inflation elevated, limiting the Federal Reserve's room to ease policy. Rising Treasury yields then put pressure on assets whose valuations depend heavily on liquidity and investor risk appetite.
The bond market has already absorbed a substantial repricing. The 10-year Treasury yield rose almost 50 basis points during September, while the Dollar gained roughly 2% against major currencies.
The Federal Reserve raised its benchmark interest rate by 25 basis points on September 16, taking the target range to 3.6-4%. The decision was unanimous, with the Federal Open Market Committee voting 12-0. It was the Fed's first rate increase since 2023.
Governor Michael Barr added to the hawkish tone on September 29, saying further policy adjustments were likely to be needed to return inflation to the Fed's 2% target in a timely manner. Barr cited persistent energy costs and demand associated with the AI investment boom as factors complicating the inflation outlook.
The market's expectations have shifted quickly. CME FedWatch showed the probability of another quarter-point increase at the October meeting falling to roughly 51.5% after New York Fed President John Williams said there was no urgency for another hike. Earlier in the week, the probability had been above 70%.
That leaves forex traders with a data-dependent setup. The September employment report is due on October 2, while the next Federal Open Market Committee meeting takes place on October 27-28. The jobs report could provide another important clue about the economy's ability to absorb higher rates.
TradFi demand remains the strongest argument against reading the pullback as a broad abandonment of Bitcoin.
A report from SoSoValue shows US spot Bitcoin ETFs attracted $2.95 billion over the 30 days to September 28 and extended their net-inflow streak to eight trading days. Monday's inflow was only $31.06 million, the smallest during the run, with BlackRock's IBIT attracting $54.82 million while Grayscale's GBTC lost $23.17 million.
Contrast those figures with mid-September, when Bitcoin ETFs lost $450.1 million on September 15, their largest daily outflow since June. The funds subsequently recorded almost $1 billion of inflows on September 21 and another $713 million the following day.
Weekly inflows eventually reached about $2.3 billion, the strongest weekly total since October 2025. Bitcoin's recovery also pushed the price above the average ETF holder's estimated cost basis of roughly $81,719, returning the typical fund investor to profit.
Derivatives markets offer another reason to treat this week's ongoing BTC price decline with caution.
Open interest across crypto derivatives stood at about $381 billion, up more than 8%, while 24-hour derivatives volume jumped 66% to roughly $837 billion. Liquidations reached $476 million, including about $386.2 million in long positions.
The imbalance suggests that leveraged bulls have absorbed most of the forced selling as Bitcoin slipped from its recent highs. High open interest can support a rally when prices rise, but it can also accelerate a decline when positions are unwound.
Total crypto market capitalization stood near $2.83 trillion, while the Crypto Fear and Greed Index remained in greed territory at around 70. A reading of 71 on September 30 kept sentiment firmly on the optimistic side of the scale.
