Key Points:
- Bitcoin fell to $82,957.64 by 7:20 a.m. ET on September 28, after opening at $84,457.30 and coming under renewed pressure from geopolitical risk.
- Ethereum declined to $2,662.70 after opening at $2,687.59, extending a broader cooling trend across major digital assets.
- Trump’s rejection of Iran’s seven-day proposal to reopen the Strait of Hormuz has reinforced concerns over oil prices, inflation and interest rates, creating another macro headwind for crypto markets.
Bitcoin and Ethereum started the final week of September under pressure as renewed geopolitical uncertainty pushed investors toward a more cautious risk posture. Bitcoin opened at $84,457.30 on Monday, September 28, before falling to $82,957.64 by 7:20 a.m. ET, while Ethereum slipped from an opening price of $2,687.59 to $2,662.70.
The move followed President Donald Trump’s rejection of an Iranian proposal to reopen the Strait of Hormuz and end hostilities within seven days. Reuters reported that Trump rejected the proposal on Saturday, while Iran had offered to reopen the strategically important waterway through a plan delivered via mediators.
Bitcoin Loses Ground as Geopolitical Risk Returns
Bitcoin’s move from $84,457.30 to $82,957.64 represents a decline of about 1.8% from the Monday opening price. The decline indicates that crypto markets remain sensitive to developments outside the digital-asset sector, particularly when geopolitical events affect energy markets and expectations for monetary policy.
Other market data showed Bitcoin trading around $83,000 later in the session, with the broader crypto market capitalization near $2.86 trillion. Bitcoin remained higher over the previous seven days despite the latest pullback, suggesting the move was occurring within a broader period of consolidation rather than after a complete reversal of the recent rally.
Ethereum Also Retreats as Risk Appetite Softens
Ethereum opened Monday at $2,687.59, approximately 0.3% below Sunday’s opening level, before moving to $2,662.70 by 7:20 a.m. ET. The decline was more limited than Bitcoin’s move during the early U.S. session, but it reflected the same broader pressure affecting major digital assets.
Market-wide derivatives activity remained elevated. Data cited by Decrypt showed approximately $382.3 billion in open interest and $838.2 billion in 24-hour derivatives volume, while liquidations reached roughly $478 million, with long positions accounting for about $386.5 million. Such positioning can amplify relatively modest spot-market declines when leveraged traders are forced to reduce exposure.
Oil, Inflation and the Federal Reserve
The geopolitical development has implications beyond crypto. The Strait of Hormuz is a critical global energy corridor, and uncertainty surrounding its reopening has pushed oil prices higher. Decrypt reported Brent crude moving back above $100 a barrel, alongside higher Treasury yields and a stronger dollar.
For Bitcoin and other non-yielding assets, that combination creates a challenging macro backdrop. Higher energy prices can increase inflation pressure, while rising Treasury yields can strengthen the relative appeal of traditional fixed-income assets. The Federal Reserve raised its benchmark rate to 3.75%–4% on September 16, its first increase since 2023, and markets are now watching incoming inflation and employment data for clues about the next policy decision.
PCE and Jobs Data Become the Next Market Tests
The timing is particularly significant because the market is entering a data-heavy week. The Federal Reserve’s preferred inflation measure, core PCE, is due Wednesday, followed by the September employment report on Friday. Traders are therefore assessing whether higher energy prices will reinforce inflation concerns or prove temporary.
For crypto investors, the interaction between geopolitical developments, oil prices, Treasury yields and Federal Reserve expectations will remain central. Bitcoin’s ability to stabilize after the move toward $83,000, alongside Ethereum’s response around $2,600–$2,700, could provide a clearer indication of whether the recent consolidation is continuing or whether macro pressures are beginning to dominate digital-asset positioning.
The immediate focus is therefore likely to remain on the September 30 PCE release, October rate expectations, oil-market developments and the September jobs report. Any easing in geopolitical or inflation pressure could alter the macro backdrop quickly, while further energy-price increases could keep liquidity-sensitive assets under pressure. For institutions, the week provides an important test of how resilient recent crypto demand remains when global macro risks intensify.
