How the US-Iran War Could Affect Oil and Bitcoin Prices (Latest Analysis)
TL;DR
- Three-phase evolution: Oil-Bitcoin correlation during the US-Iran war shifted from positive (Feb 28-Mar 15) to weak (Mar 16-23) to negative/zero (Mar 24-Apr 6), confirming no stable relationship exists between the two assets.
- Positive Oil-Bitcoin correlation drivers: Shared liquidity factor, inflation hedge repricing, and institutional demand (JPMorgan data showed 1.5% net inflows into BTC ETFs vs 2.7% outflows from gold ETFs) explained early co-movement.
- Negative correlation mechanism: Sustained high oil prices → persistent inflation fears → Fed signals no rate cuts → 10-year yield hits 4.42% → dollar strengthens → risk assets (including Bitcoin) reprice downward.
- Decoupling factors: Bitcoin traded independently due to crypto-specific supports: Iran's "toll" mechanism (crypto fees for Strait passage), gold's 106-year losing streak driving digital gold repricing, and institutional ETF flows ($22.3M in late March) absorbing macro shocks.
The outbreak of the US-Iran war on February 28, 2026, has provided an unprecedented real-time laboratory for understanding how geopolitical oil shocks interact with an increasingly institutionalized cryptocurrency market. This article examines the relationship between crude oil prices and Bitcoin throughout the conflict, analyzing price movements, correlation patterns, and the underlying transmission mechanisms.
Price Trajectories — Comparing Oil and Bitcoin Since the Outbreak of War
Between February 28 and April 6, 2026, the oil-Bitcoin relationship shifted through three phases:
- The first phase showed a positive correlation, with both assets rising sharply.
- The second phase exhibited weak correlation, as oil continued climbing while Bitcoin moved sideways.
- The third phase turned to negative-to-zero correlation, with oil advancing further while Bitcoin remained flat to slightly lower.
This progression confirms that oil and Bitcoin returns are statistically independent processes, with any correlation being episodic rather than stable .
Table: Oil and Bitcoin Price Performance by Phase (Feb 28 - Apr 6, 2026)
| Phase | Period | Oil Price Change | Bitcoin Price Change | Correlation |
| Phase 1: Initial Crisis | Feb 28 - Mar 15 | +40-50% (Brent from ~$71 to ~$100+) | +12% (from $65,900 to ~$74,000) | POSITIVE |
| Phase 2: Hormuz Closure | Mar 16 - Mar 23 | +15-20% (Brent ~$100-118) | +2-5% (range-bound) | WEAK |
| Phase 3: Prolonged Conflict | Mar 24 - Apr 6 | +10-15% (Brent $110-126) | -5% to flat ($66,000-69,000 range) | NEGATIVE TO ZERO |
The Correlated Phase — Transmission Mechanisms from Oil to Bitcoin
During the initial crisis phase (February 28 - March 15) , oil and Bitcoin exhibited a clear positive association. However, it is critical to distinguish this from a causal relationship, which is best explained by a shared liquidity factor rather than any direct causal link.
The Positive Correlation Mechanism
During the first two weeks, three channels drove positive co-movement:
Channel 1: Shared Liquidity Factor – Markets priced in "regime change" and rapid resolution, triggering a broad risk-on move that lifted both oil (supply disruption) and Bitcoin (risk appetite) simultaneously.
Channel 2: Inflation Hedge Repricing – With oil above $100 signaling impending global inflation, Bitcoin's fixed supply (annual inflation rate of just 0.8%) positioned it as a potential store of value.
Channel 3: Institutional Demand – JPMorgan data showed Bitcoin ETFs saw 1.5% net inflows during the conflict, while the largest gold ETF experienced 2.7% outflows. BlackRock and Fidelity aggressively accumulated Bitcoin during the pullback, and the Bitcoin-to-Gold ratio rebounded approximately 30% from its lows .
In summary, a combination of liquidity-driven risk appetite, inflation hedging demand, and institutional capital flows explained the positive correlation between oil and Bitcoin in the first two weeks of the war.
The Negative Correlation Mechanism
Sustained high oil prices generate persistent inflation fears, which prompt the Federal Reserve to signal no rate cuts while markets begin pricing in possible hikes. This pushes the 10-year Treasury yield up to 4.42 percent, a nine-month high, and strengthens the US dollar. As a result, risk assets—including Bitcoin—reprice downward. This chain explains how oil shocks transmit to Bitcoin during the negative correlation phase.

The Decoupling Phase — When Bitcoin Traded Independently
The clearest decoupling emerged during the Hormuz closure period (mid-to-late March) and has continued into early April. During this phase, oil continued its relentless march higher (from ~$100 to ~$115-126), while Bitcoin stabilized in a range ($65,000-72,000), neither following oil upward nor crashing with traditional equities.
Why Did Bitcoin Decouple?
While macro factors pressured Bitcoin, several crypto-specific factors provided independent support:
- The "Toll" Mechanism: According to Bloomberg News, Iran's Islamic Revolutionary Guard Corps began charging ships passing through the Strait of Hormuz fees in cryptocurrencies, including Bitcoin. If formalized, this could generate up to $120 billion annually for Iran at pre-war volumes, creating structural, industrial demand for Bitcoin independent of financial market dynamics .
- The "Digital Gold" Repricing: Between March 11 and March 24, 2026, gold recorded 10 consecutive daily losses—its longest losing streak in over a century. Some investors began re-evaluating Bitcoin as a superior alternative — lighter, more portable, with verifiable scarcity, and operating 24/7/365 without counterparty risk .
- Geopolitical Utility: In sanctioned or conflict zones, Bitcoin's permissionless nature makes it the only available channel for cross-border value transfer. Following the Iranian airstrikes, Iran's largest crypto exchange Nobitex saw withdrawal volumes spike to $3 million per hour.
- Institutional Absorption of Macro Shocks: The presence of major ETF providers (BlackRock, Fidelity) and corporate treasuries (MicroStrategy) created a "structural bid" that was absent in previous geopolitical crises. Spot BTC ETF inflows remained resilient, recording $22.3 million in inflows during the last week of March despite heightened uncertainty. This institutional presence acts as a buffer against pure panic selling.
The net effect was range-bound stability — Bitcoin neither crashed nor rallied, while oil continued its one-way march higher. This demonstrates that decoupling (no correlation) is distinct from negative correlation; in this phase, the transmission chain was interrupted by crypto-specific factors.
Which Factor Dominates?
ETF flows currently carry the most weight. As The Edge Singapore reported (April 6), “Bitcoin’s rise appears driven by steady spot demand, with ETF flows remaining firm,” said Gracie Lin, chief executive officer of crypto exchange OKX SG. “Price action remains orderly and funding is contained, suggesting the move is being led by incremental allocation rather than leverage.”
Final Thought for WEEX Users
The US-Iran war of 2026 is demonstrating that Bitcoin has matured from a speculative asset into a multi-dimensional instrument — part risk asset, part digital gold, part geopolitical utility. The old pattern of "Bitcoin crashes on every crisis" has been replaced by a more nuanced reality.
For WEEX traders, this means opportunity — but only for those who understand which phase the market is in and which transmission channel is active. The oil-Bitcoin relationship is not fixed; it evolves. Trade accordingly and DYOR.

Mixin has launched USTD-margined perpetual contracts, bringing derivative trading into the chat scene.
The privacy-focused crypto wallet Mixin announced today the launch of its U-based perpetual contract (a derivative priced in USDT). Unlike traditional exchanges, Mixin has taken a new approach by "liberating" derivative trading from isolated matching engines and embedding it into the instant messaging environment.
Users can directly open positions within the app with leverage of up to 200x, while sharing positions, discussing strategies, and copy trading within private communities. Trading, social interaction, and asset management are integrated into the same interface.
Based on its non-custodial architecture, Mixin has eliminated friction from the traditional onboarding process, allowing users to participate in perpetual contract trading without identity verification.
The trading process has been streamlined into five steps:
· Choose the trading asset
· Select long or short
· Input position size and leverage
· Confirm order details
· Confirm and open the position
The interface provides real-time visualization of price, position, and profit and loss (PnL), allowing users to complete trades without switching between multiple modules.
Mixin has directly integrated social features into the derivative trading environment. Users can create private trading communities and interact around real-time positions:
· End-to-end encrypted private groups supporting up to 1024 members
· End-to-end encrypted voice communication
· One-click position sharing
· One-click trade copying
On the execution side, Mixin aggregates liquidity from multiple sources and accesses decentralized protocol and external market liquidity through a unified trading interface.
By combining social interaction with trade execution, Mixin enables users to collaborate, share, and execute trading strategies instantly within the same environment.
Mixin has also introduced a referral incentive system based on trading behavior:
· Users can join with an invite code
· Up to 60% of trading fees as referral rewards
· Incentive mechanism designed for long-term, sustainable earnings
This model aims to drive user-driven network expansion and organic growth.
Mixin's derivative transactions are built on top of its existing self-custody wallet infrastructure, with core features including:
· Separation of transaction account and asset storage
· User full control over assets
· Platform does not custody user funds
· Built-in privacy mechanisms to reduce data exposure
The system aims to strike a balance between transaction efficiency, asset security, and privacy protection.
Against the background of perpetual contracts becoming a mainstream trading tool, Mixin is exploring a different development direction by lowering barriers, enhancing social and privacy attributes.
The platform does not only view transactions as execution actions but positions them as a networked activity: transactions have social attributes, strategies can be shared, and relationships between individuals also become part of the financial system.
Mixin's design is based on a user-initiated, user-controlled model. The platform neither custodies assets nor executes transactions on behalf of users.
This model aligns with a statement issued by the U.S. Securities and Exchange Commission (SEC) on April 13, 2026, titled "Staff Statement on Whether Partial User Interface Used in Preparing Cryptocurrency Securities Transactions May Require Broker-Dealer Registration."
The statement indicates that, under the premise where transactions are entirely initiated and controlled by users, non-custodial service providers that offer neutral interfaces may not need to register as broker-dealers or exchanges.
Mixin is a decentralized, self-custodial privacy wallet designed to provide secure and efficient digital asset management services.
Its core capabilities include:
· Aggregation: integrating multi-chain assets and routing between different transaction paths to simplify user operations
· High liquidity access: connecting to various liquidity sources, including decentralized protocols and external markets
· Decentralization: achieving full user control over assets without relying on custodial intermediaries
· Privacy protection: safeguarding assets and data through MPC, CryptoNote, and end-to-end encrypted communication
Mixin has been in operation for over 8 years, supporting over 40 blockchains and more than 10,000 assets, with a global user base exceeding 10 million and an on-chain self-custodied asset scale of over $1 billion.
