Bitcoin Shakes Off Iran Strike Shock, But ETF Flows May Decide Monday’s Direction

Bitcoin once again absorbed a major geopolitical shock over the weekend, whipsawing lower on news of U.S. and Israeli strikes on Iran before quickly recovering to the mid-$64,000 region. The initial selloff unfolded in thin weekend liquidity, but attention is already shifting to a familiar driver in the ETF era: how U.S. spot Bitcoin exchange-traded funds (ETFs) trade when markets reopen on Monday.

Weekend Shock: Iran Strikes and a Fast Bitcoin Rebound

Bitcoin traded through a volatile macro backdrop after reports of U.S. and Israeli strikes on Iran sparked regional retaliation and a wave of risk-off positioning. The sharpest price swings occurred during low-liquidity weekend hours, creating a rapid flush and equally fast rebound that left spot BTC hovering around the mid-$64,000 area by late weekend.

This price action fits a pattern that has become more visible since spot Bitcoin ETFs launched in the U.S. in 2024. Bitcoin continues to act as a 24/7 “pressure valve” for global macro risk, repricing quickly when traditional markets are closed. But the deepest pools of marginal liquidity are now concentrated in weekday, regulated venues—particularly U.S.-listed ETFs and major exchanges like Coinbase.

The result is a structural split: Bitcoin trades continuously, but the largest and most price-relevant capital now moves when U.S. markets are open. Weekend moves can therefore be exaggerated in both directions, with thin order books amplifying geopolitical headlines before ETF flows help decide whether those moves stick.

Liquidity Shift: ETF Era Reshapes Weekend Trading

Data since the launch of spot Bitcoin ETFs shows a steady capitulation of weekend activity, even as weekday trading has ramped higher. Last week underscored this divergence: volumes during the week surged—especially on Coinbase—while weekend participation dropped off sharply.

That divergence matters for traders. With less depth on weekends, “air pockets” in the order book widen, increasing the odds of sharp intraday crashes and equally violent reversals when macro news hits. We have already seen similar dynamics recently, including a flash crash below $65,000 tied to delayed market reaction to additional Trump tariff hikes during low weekend liquidity.

In practical terms, the ETF structure has pulled a large share of institutional and systematic capital into Monday–Friday, U.S.-hours channels. Spot ETFs only trade on weekdays, and many large players that might have once leaned into offshore or crypto-native venues now prefer regulated, on-exchange exposure. That means:

• Weekend moves are often driven by thinner, more speculative flow.
• Price discovery increasingly “resets” when ETFs open in New York.
• Geopolitical or macro headlines over the weekend can cause outsized volatility but may be faded—or extended—depending on what ETF flows look like after the open.

For traders, the key takeaway is that weekend candles tell only part of the story. The follow-through—or lack of it—often comes from ETF create-redeem activity once Wall Street is back online.

All Eyes on Monday: ETF Flows as the Key ‘Next Open’ Variable

Heading into Monday, the market’s focus narrows to a small set of variables that will determine whether this weekend’s rebound holds or unravels. At the center is the spot ETF flow channel, which now acts as a primary gauge of U.S. demand for Bitcoin.

Recent market coverage has highlighted renewed inflows into spot Bitcoin ETFs, with reported multi-day net inflows topping about $1 billion over three sessions, even as price action remained choppy. That shows that institutional or advisor-led demand can be strong even in a volatile tape.

However, the bigger picture remains uneven. By mid-February, year-to-date net flows across U.S. spot Bitcoin ETFs were still negative by roughly $2.6 billion. That imbalance explains why rebounds like this weekend’s can be sharp—thin liquidity plus sudden buying—but also why they can be capped when headline risk is high and large pools of capital remain cautious.

Two broad Monday scenarios now loom:

• Constructive ETF flows > continuation: If U.S. traders once again flood into spot ETFs as they did last week, and if Bitcoin holds its current “lower high” through the rest of the weekend, the recovery could extend. Robust create activity would validate the rebound and re-anchor BTC above key support.
• Soft or negative flows > renewed downside: If Bitcoin opens the week trading in the $63,000–$61,000 band, a jittery U.S. open combined with weak ETF prints could pull the market down further, especially if risk-off sentiment lingers across rates, FX, and energy markets.

Traders are also watching the Chicago Mercantile Exchange (CME) futures “gap” dynamic. When CME Bitcoin futures close for the weekend while spot markets remain open, large price moves can leave unfilled gaps on the futures chart. Some market participants treat these levels as magnets that price tends to revisit, shaping positioning into the reopen. While not a certainty, these gaps add another layer of complexity to Monday’s setup.

Macro Cross-Currents: Tariffs, Rates, Energy and the Iran Channel

This weekend’s volatility did not occur in isolation. It landed on top of an already loaded macro and policy calendar, keeping Bitcoin firmly in the crosshairs of broader risk sentiment.

Earlier in the week, U.S. trade policy uncertainty shook markets after the Supreme Court constrained former President Trump’s use of emergency powers for tariffs, forcing a strategic pivot. In the wake of that ruling, attention turned to Section 122 authorities and a proposed flat 15% tariff, reintroducing uncertainty around the U.S. trade outlook.

Cross-asset moves around that sequence—gold’s response to tariff risk and a softer U.S. dollar tied to trade uncertainty—positioned Bitcoin as part of a wider policy-risk complex rather than a purely crypto-native story. Markets are also eyeing potential liquidity shifts from tariff-related refund battles moving through trade courts, which could ultimately alter broader risk appetite.

Against this backdrop, the Iran channel adds another macro layer. Markets typically watch energy flows because oil is the clearest transmission mechanism from Middle East geopolitics into inflation expectations, interest rates, and the dollar. Axios has highlighted the Strait of Hormuz as a key chokepoint, carrying roughly 25% of global maritime oil trade and about 20% of LNG shipments. Any perceived threat to that corridor can quickly feed into higher crude prices.

Separate reporting has emphasized crude price sensitivity and the likely response function from OPEC+, which will help determine whether this weekend’s tension fades into relief or hardens into a more sustained, rates-driven risk-off environment. If oil gaps higher and stays bid, the first-order market reaction tends to be:

• Higher inflation expectations
• Firmer yields
• A stronger dollar

That combination has historically pressured risk assets, including Bitcoin, even when an initial geopolitical selloff has already occurred. How energy markets trade into Monday will therefore be a critical input for crypto as well.

Key Price Levels: Mapping Support, Resistance and Scenarios

From a technical perspective, the current battleground can be mapped around a handful of clearly defined levels that separate “contained escalation” from a more serious “energy shock” outcome.

Based on the recent move, traders are watching:

Level	Role	Why it matters into the reopen
$64,700	Primary support zone	This area was defended during the weekend shock. Holding above it keeps the rebound thesis intact.
$65,400	First reclaim	Reclaiming this level turns a simple bounce into a credible attempt at trend resumption.
$63,800	Breakdown shelf	Losing this shelf shifts focus to lower supports and increases the probability of deeper stop cascades.
$62,850	Deeper support	A failure here would increase attention on a broader move toward round-number support levels below.
$69,270–$70,730	Resistance band	This zone near prior highs will likely require sustained risk appetite and consistently positive ETF flows to break.

In a contained-escalation scenario—where energy markets stabilize and geopolitical risk does not meaningfully escalate—traders will look first to whether Bitcoin can hold roughly $64,700 into the U.S. reopen and then recapture $65,400. A successful reclaim, coupled with constructive ETF flows, would put the $69,000–$70,000 band back into play.

The more adverse path is tightly linked to the energy and rates complex. If crude gaps higher and remains strong, yields and the dollar could firm, pressuring Bitcoin even if it already sold off once on the headline. In that case, a sustained move below about $63,800 would bring $62,850 into focus, with broader round-number support levels becoming the next reference points if those shelves fail.

What Traders Should Watch Into the U.S. Reopen

For crypto traders and macro-focused Bitcoin investors, the next 24–48 hours center on confirmation rather than prediction. The weekend has already revealed that Bitcoin can still act as a 24/7 shock absorber in a world where the most important capital flows through weekday ETF pipes. Monday will determine whether that shock is ultimately faded or compounded.

Key checklists heading into the U.S. open include:

• Spot ETF flows: Are we seeing repeat strong inflows, flat prints, or renewed net outflows? This will be the primary signal of U.S. demand.
• Energy markets and OPEC+ tone: Does crude spike and stay bid, or does it fade as tensions cool? The answer feeds directly into inflation expectations and risk appetite.
• Rates, FX and the dollar: Are yields and the dollar firming on inflation and tariff risk, or softening on growth and policy concerns? Bitcoin has been trading as part of this broader policy-risk complex.
• Technical structure: Does BTC hold above $64,700 and reclaim $65,400, or does it slip into the $63,800–$62,850 zone and trigger deeper liquidations?

With weekend liquidity structurally thinner in the ETF era, the real verdict on this Iran-related shock will likely come when U.S. markets reopen and the next set of ETF flow numbers print. Until then, Bitcoin’s swift rebound is less a resolution than a prelude to Monday’s decision point.
