Spot bitcoin ETFs saw $390 million in net outflows in the week to Aug. 14, the heaviest weekly drain since early July, as escalating Middle East tensions and a surge in oil prices prompted investors to pull back. Fidelity's FBTC led the retreat with $153 million exiting the fund, while ethereum spot ETFs also bled $2.26 million between Aug. 10 and Aug. 14. Bitcoin itself held near $63,500, showing resilience despite the selling.
Oil, fertilizer and the Strait of Hormuz
The outflows come as Brent crude pushed above $88 a barrel in the week to Aug. 15, up more than 5%, with WTI reaching $82.83. Both benchmarks gained over 5% last week. JPMorgan flagged that nitrogen fertilizer benchmarks jumped 25% to 50% since the conflict began, and the World Bank's fertilizer index sits near its highest since 2022. The Middle East ships close to a quarter of the world's urea through the Strait of Hormuz, and the US has said its naval blockade of Iran could run indefinitely while talks to reopen the strait stay deadlocked. JPMorgan sees the fertilizer ripple lifting global food inflation toward 4% to 5%.
Whales thin out
On-chain data shows wallets holding 1,000 or more BTC peaked near 1,963 on July 31, then thinned steadily through August. The whales' 30-day change turned net negative around Aug. 10, aligning with the ETF outflows. The $390 million weekly outflow reversed the $853 million absorbed the week before.
A familiar pattern?
Geopolitical shocks have a mixed track record with bitcoin. Russia's invasion of Ukraine in February 2022 saw bitcoin fall about 9% in two days, then rebound roughly 15% within five weeks. The 2023 Israel-Hamas war barely moved it, and June 2025's Israel-Iran flare-up knocked BTC about 4% before a ceasefire sparked recovery. This time, the blockade and deadlocked talks mean no clear end in sight, so the question is whether the dip gets bought or the standoff drags risk assets lower.
For now, bitcoin is holding above $63,500, but the week's outflows suggest investors aren't ready to add exposure while oil and fertilizer prices keep climbing. The next concrete test is whether the blockade talks make progress or the standoff drags on.
