Why Is Bitcoin Falling Toward $70K? ETF Outflows and a Stronger Dollar Are Squeezing the Market

Bitcoin lost the $73,000 level overnight and is now testing the zone traders have defended for weeks. This selloff has a clear cause. Three measurable forces are driving it, and one of them just flashed a warning that hasn’t appeared since December.

The short version

Bitcoin is trading near $72,800 in early Asian hours on May 28, down from highs above $82,000 earlier this month. That works out to roughly an 11% drawdown in three weeks, and it leaves BTC down more than 11% year-to-date.

This drop came from three things stacking on top of each other: institutional money leaving Bitcoin ETFs, a stronger US dollar driven by hawkish Fed signals, and risk-off pressure from Middle East tensions. Below we cover each one, plus why the $70,000 line is now the level everyone is watching.

1. The ETF bid is gone, and that’s the real story

For most of 2025, US spot Bitcoin ETFs were the structural buyer holding the market up. That engine has stalled.

The funds have now logged six consecutive days of outflows, with roughly $1.26 billion pulled out during the May 18 to 22 window alone. That was the largest weekly outflow since late January. BlackRock’s IBIT, the dominant fund, led the exits.

Here’s the number that actually matters, and most coverage is missing it: US spot ETFs have absorbed only about 4,500 BTC all year. Compare that to April, when they soaked up roughly 19,000 BTC in a single nine-day streak, about nine times the new supply mined in that period. The buyer that powered the last rally has flipped from accumulation to distribution.

Why this moves price mechanically: when ETF money flows in, market makers must buy real Bitcoin on exchanges to mint new shares, and that demand hits the order book directly. When money flows out, the reverse happens, and actual BTC gets sold to honor redemptions. With less coin sitting on exchanges after a year of accumulation, that selling now bites harder than it used to.

2. A hawkish Fed and a stronger dollar

Bitcoin trades like a risk-on asset, and right now the macro backdrop is hostile to risk.

Fed Governor Christopher Waller’s May 22 speech signaled a hawkish stance on inflation, which cooled hopes for rate cuts. Treasury yields are pricing in “higher for longer,” and a stronger dollar typically pulls money out of speculative assets like crypto.

This pattern has held all year. Rising yields have lined up with ETF outflows, while falling yields have preceded inflows. A meaningful share of ETF investors treat Bitcoin through a pure macro lens. They buy it when money is loose and dump it when policy tightens. Right now, policy is tightening.

3. Geopolitics added the final shove

On top of the macro picture, renewed Middle East escalation pushed oil prices higher and sent capital toward safe havens. For a leveraged, sentiment-driven market like crypto, that’s the kind of headline that triggers stop-losses and forced liquidations, accelerating a move that was already underway.

The result is a feedback loop: weaker spot demand leads to softer price action, which leads to more ETF redemptions, which leads to more selling. Corporate Bitcoin buying also slowed sharply in mid-May, dropping as much as 80% from earlier peaks, which removed another source of demand.

The levels that matter now

This is where readers actually want a view rather than a hedge. Here’s the structure:

$73,000 to $75,000: the support zone bulls have defended for weeks through fresh leveraged longs. BTC just lost the lower edge of it overnight.

$70,000: the next major floor. One on-chain risk gauge (Swissblock) just moved into “high-risk” territory, warning that ETF demand is too thin to absorb selling pressure. A clean break of $73K opens the door here.

$76,900 to $78,000: the reclaim level. Pushing back above this would force shorts to cover and flip the short-term tone. Until then, sellers hold control.

What would change the picture: a single strong day of ETF inflows, or a clean break back above $77K. Neither has happened yet. Some technical signals, like a potential golden cross, remain constructive, but flows and macro are overwhelming them for now.

What we’re watching next

The cleanest daily signal isn’t the price chart. It’s the ETF flow number. As long as it stays negative, rallies are likely to be sold. The May 29 options expiry, with “max pain” clustered near $75,000, could add volatility into the weekend. And the next batch of yield and inflation data will tell us whether the macro headwind eases or hardens.

For now, the burden of proof sits with the bulls.

FAQ

Why is Bitcoin going down today? Three reasons at once: six straight days of Bitcoin ETF outflows (~$1.26B), a stronger US dollar after hawkish Fed signals, and risk-off pressure from Middle East tensions. The loss of the institutional ETF bid is the biggest single factor.

Will Bitcoin recover? A sustained rebound likely requires ETF flows to turn positive again or a clean break back above $77,000. Until one of those happens, analysts expect rallies to face selling pressure. The next defended floor sits around $70,000.

Is the Bitcoin bull run over? Not necessarily. Bitcoin remains well below its 2025 peak near $126,000 and is in a correction rather than a confirmed reversal. The market structure depends heavily on whether institutional ETF demand returns.
