Bitcoin ETF Inflows Accelerate as US-Iran Diplomacy Lifts Risk Appetite
Bitcoin is holding near $64,000 as US spot Bitcoin ETFs pulled in more than $170m of net inflows on 4 August 2026, with BlackRock's IBIT alone accounting for $111.43m. The move comes as easing US-Iran tensions and progress on US crypto legislation improve broader risk appetite.
Here's what's behind the inflows, what else is moving Bitcoin's price today, and what UK investors should weigh up before treating an ETF flow number as a trend.
Key takeaway
- US spot Bitcoin ETFs saw over $170m in net inflows on 4 August 2026, nearly matching all of July's inflows in a single day.
- BlackRock's IBIT contributed $111.43m of that total, according to CaptainAltcoin's market data round-up.
- Bitcoin (BTC) is trading around $64,000-$64,270, up modestly over 24 hours as of 5 August.
- Progress toward reopening the Strait of Hormuz has eased geopolitical risk and lifted broader risk assets, including crypto.
- Senate Majority Leader John Thune confirmed on 3 August that the CLARITY Act will get a floor vote before recess, but a 60-vote filibuster threshold and an unresolved ethics dispute make passage genuinely uncertain.
- BTC's price still correlates roughly 63% with the S&P 500 and 58% with gold — macro conditions matter as much as crypto-specific news.
Why Are Bitcoin ETF Inflows Rising?
US spot Bitcoin ETFs recorded net inflows of more than $170m on 4 August 2026 — almost matching the entire month of July in a single trading day, according to market data reported by CaptainAltcoin. That buying has helped absorb selling pressure and supported Bitcoin's recovery from the $62,200-$64,000 range it had been trading in.
BlackRock's IBIT Leads the Charge
BlackRock's iShares Bitcoin Trust (IBIT) was the single largest contributor, pulling in $111.43m of the day's inflows. IBIT has consistently been the largest US spot Bitcoin ETF by assets since spot ETFs launched, and its flows are often treated as a proxy for institutional sentiment toward Bitcoin more broadly.
Quick fact
Bitcoin's price is roughly 63% correlated with the S&P 500 and 58% correlated with gold, according to CaptainAltcoin's 5 August market analysis — a reminder that macro conditions still drive much of its short-term movement.
What Else Is Driving Bitcoin's Price Today?
Bitcoin's steadiness above $64,000 isn't only about ETF demand. Two other threads are shaping sentiment this week.
Easing Middle East Tensions
Reports that the US, Qatar and Iran are making progress toward reopening the Strait of Hormuz have reduced geopolitical risk and supported a broader "risk-on" mood across markets, including crypto. Bitcoin rose on 4 August partly on renewed optimism that the strait may reopen soon, alongside similar moves in equities and a pullback in oil prices.
The CLARITY Act's Progress Through Congress
Crypto market participants are also watching the CLARITY Act, a proposed US bill intended to clarify how digital assets are regulated. Senate Majority Leader John Thune confirmed on 3 August 2026 that the bill will receive a floor vote before the Senate's August recess — but clearing the 60-vote filibuster threshold still depends on resolving an ethics dispute with Democratic negotiators. Prediction markets Polymarket and Galaxy Research put the odds of the bill becoming law in 2026 at roughly 30-33%, reflecting how unresolved this remains.
| Factor | Direction | Why it matters |
| US spot Bitcoin ETF flows | Net inflow, $170m+ (4 Aug) | Signals institutional demand absorbing sell pressure |
| US-Iran / Hormuz diplomacy | De-escalating | Improves broad risk appetite across asset classes |
| CLARITY Act (US Congress) | Floor vote confirmed, passage uncertain | 60-vote threshold and ethics dispute unresolved as of 3 Aug |
| Coldcard wallet exploit | Ongoing, escalating | Over 1,800 BTC (~$114m) stolen across a fourth attack wave |
What Risks Remain for Bitcoin?
Not all the news has favoured bulls. The Coldcard hardware wallet exploit has escalated rather than resolved — a firmware bug from 2021 made device seeds guessable, and attackers have now drained more than 1,800 BTC (around $114m) across a fourth wave of attacks, according to Coinbase's market updates. Around 32,000 BTC have also moved onto exchanges, a pattern some traders watch as a potential precursor to selling pressure. Bitcoin's price has also fallen sharply from its 52-week high near $126,198 reached in October 2025, underlining how volatile the asset remains.
Past performance is not a reliable indicator of future results, and single-day ETF inflow figures are not a reliable predictor of where Bitcoin's price goes next.
What Does This Mean for UK Crypto Investors?
For UK investors, the inflow data and the Hormuz/CLARITY Act backdrop are useful context, not a signal to act on. Bitcoin remains a highly volatile, largely unregulated asset with no consumer protection, and tax on profits may apply. Anyone considering exposure should weigh position size and volatility tolerance carefully rather than reacting to a single day's flow numbers.

How to Get Exposure to Bitcoin
UK investors and traders have a few routes to Bitcoin exposure, each with a different risk profile:
- Direct ownership — buying and holding Bitcoin on an exchange or in a private wallet.
- US spot Bitcoin ETFs — where accessible, providing exposure without directly holding the asset.
- Derivative products such as CFDs — allowing traders to speculate on price moves without owning Bitcoin, using leverage.
- A demo account — a way to practise before committing real capital, given how volatile this market can be.
Trading Bitcoin derivatives with leverage means losses can exceed your initial deposit.
- Bitcoin ETF flow data is published daily and can be a useful sentiment gauge, but it lags price action rather than predicting it.
- Bitcoin's correlation with traditional risk assets like the S&P 500 means macro news often moves crypto prices as much as crypto-specific headlines.
- Regulatory developments like the CLARITY Act can take months or years to resolve — treat legislative headlines as a slow-moving backdrop, not a near-term catalyst.
FAQ
Why are Bitcoin ETF inflows rising?
US spot Bitcoin ETFs recorded more than $170m in net inflows on 4 August 2026, led by BlackRock's IBIT with $111.43m, as institutional buying absorbed selling pressure and Bitcoin recovered from a recent dip.
What is the CLARITY Act?
The CLARITY Act is a proposed US bill aimed at clarifying the regulatory framework for digital assets. A Senate floor vote was confirmed for before the August recess, but reaching the 60 votes needed to overcome a filibuster remains uncertain, with prediction markets putting 2026 passage odds at roughly 30-33%.
Is Bitcoin's rise today linked to the Middle East?
Partly. Reports of progress toward reopening the Strait of Hormuz have eased geopolitical tension and supported broader risk appetite, which has coincided with — though isn't the sole cause of — Bitcoin's recent stability above $64,000.
Is Bitcoin a safe investment?
Cryptoassets are highly volatile and largely unregulated, with no consumer protection, and tax on profits may apply. This is general information, not personalised advice — anyone considering Bitcoin exposure should assess their own risk tolerance or seek independent advice.
