Since the US-Iran conflict escalated in 2026, volatility across global markets has revived an old question: can cryptocurrency function as a financial fallback when traditional systems falter? Supporters argue that decentralised networks allow money to move even when banks, payment rails or currencies face disruption.

The reality is more complicated. While crypto can offer alternative ways to transfer funds across borders, it remains volatile, heavily regulated and dependent on internet infrastructure and exchanges.

The conflict also triggered sharp movements across financial markets. Anndy Lian, author and intergovernmental blockchain adviser, notes that equities declined during parts of the market volatility while bitcoin briefly outperformed.

Cryptocurrency networks operate independently from banks, allowing users to send funds directly using digital wallets. That capability has made crypto attractive during moments of instability, when traditional financial channels slow down or stop entirely.

One of the clearest examples came during the Russian invasion of Ukraine. More than $212 million in cryptocurrency has been donated to pro-Ukrainian war efforts. Around $80 million of that went directly to the Ukrainian government.

Prices typically fall alongside other risk assets during the early stages of a crisis before recovering as market activity stabilises. “Markets stabilise or rise within weeks as utility outweighs fear,” Lian says.

During periods of volatility, many users move towards stablecoins rather than more volatile assets such as bitcoin.

Stablecoins such as USDT and USDC often see increased activity during crises because they are pegged to the US dollar. That allows users to hold a relatively stable digital asset while still transferring funds across borders without relying on banks.

Their total market value has surpassed $315 billion, reflecting growing demand for dollar-linked digital liquidity. Gracy Chen, CEO of Bitget, says the trend shows rising demand for stablecoins as a way to store and move value during periods of financial uncertainty.

Humanitarian organisations have also experimented with crypto donations. UNRWA USA, for example, partnered with the Giving Block to accept bitcoin, Ethereum and other digital assets to support Palestinian refugees.

During geopolitical crises, cryptocurrency platforms often tighten compliance measures to meet sanctions and regulatory requirements. Exchanges may block sanctioned addresses, restrict accounts in certain jurisdictions or increase monitoring of suspicious transactions.

During the 2022 Russia-Ukraine war, Binance restricted accounts held by Russian users with balances above $10,000 and Coinbase froze more than 25,000 Russia-linked IPs.

Amid the 2026 Iran-US conflict, platforms have also increased scrutiny of transactions connected to sanctioned jurisdictions. Chen says these measures balance compliance with accessibility.

Crypto analyst Rume Ophi notes that while digital assets can provide alternative ways to move money during crises, the ecosystem still depends heavily on centralised exchanges and regulated on-ramps. That means governments can still restrict access to platforms or monitor transactions, limiting crypto’s usefulness as a complete escape from financial controls.

Despite its appeal during periods of financial instability, cryptocurrency remains an imperfect fallback. Prices can swing sharply during geopolitical shocks, exchanges remain subject to sanctions and regulations, and access to crypto often still depends on the same financial infrastructure it aims to bypass.

As conflicts disrupt markets and banking systems, crypto may offer an alternative way to move money across borders. But as recent crises have shown, it functions less as a replacement for traditional finance than as a parallel system that operates alongside it – with its own risks and limitations.
