Fidelity Digital Assets Signals Shift Away from Dollar-Based Systems

The convergence of geopolitics, macro trends, and crypto-market dynamics is shaping a new narrative around cross-border settlement. A Fidelity Digital Assets report released this week frames Iran’s recent moves to use Bitcoin for oil tolls and a broader shift in central bank reserves—where gold still commands heft—as signs of a developing ecosystem of alternative settlement mechanisms that could challenge dollar-centric norms over time.

Concurrently, the broader gold narrative remains nuanced. While gold is down from its January peak, central banks continue to accumulate, underscoring a persistent demand for a traditional store of value even as digital assets attract attention for potential reserve-like roles. Against this backdrop, Tehran has moved from discussions to concrete steps that could redefine how energy payments travel across borders. In April 2026, Iran publicly signaled it would accept oil shipping tolls in Bitcoin, alongside U.S. dollar-pegged stablecoins and the Chinese yuan. The development follows earlier signals in 2025 about an insurance-based framework for Hormuz transits and illustrates a willingness to experiment with non-traditional settlement rails in the energy sector.

Meanwhile, questions remain about the resilience and regulatory reach of these arrangements. U.S. authorities have acted to constrain certain crypto-tied assets linked to Iran, including a notable freeze of stablecoins valued at hundreds of millions of dollars. In this environment, Bitcoin-related settlement appears to be advancing even as fiat and stablecoin channels continue to grapple with sanctions enforcement and policy risk. Observers note that while stablecoins face action from regulators, neutral settlement rails could gain practical traction in select corridors where banks and counterparties prioritize speed, transparency, and censorship-resistance.

Key takeaways

• Iran’s oil toll settlements are expanding beyond the U.S. dollar, with Bitcoin, USD-pegged stablecoins, and the yuan all part of the toolkit as of April 2026, signaling a broader exploration of non-dollar rails for energy payments.
• Fidelity Digital Assets’ 2026 trends report describes these developments as part of “alternative settlement mechanisms” that could contribute to a gradual shift away from dollar-centric systems, even if the transition remains nascent.
• Gold remains a focal point for central banks, continuing to hold a central role despite a roughly 20% retreat from its all-time high, highlighting a split between traditional reserves and emerging crypto narratives about the future of money.
• Stablecoins linked to Iran faced regulatory action from the United States, underscoring the fragility of sanction-era crypto flows while Bitcoin-based tolls gain practical traction in certain corridors, according to market observers.
• The sector’s early, policy-driven experiments trace back to 2025, when Iran publicly explored an insurance-based model for Hormuz transits payable in Bitcoin, illustrating a longer arc toward non-traditional settlement infrastructure.

Iran’s experiment with Bitcoin-friendly tolls and the evolution of cross-border settlement

Telegram chatter and policy briefs aside, Tehran’s approach has moved into the procurement phase. The Strait of Hormuz—through which a substantial share of the world’s oil passes—has long been a focal point for strategic signaling. In 2025, Iranian state media reported that the government was weighing a maritime insurance framework to govern Hormuz transits, with Bitcoin cited as a potential payment instrument and “settled at the speed of blockchain.” The plan was described as enabling the issuance of various marine insurance policies and certificates of financial responsibility, signaling an intent to layer crypto-influenced mechanics onto traditional shipping finance models.

By 2026, the policy posture had evolved toward concrete toll payment options. Iranian officials announced that oil shipping tolls could be settled using Bitcoin, alongside dollar-linked stablecoins and the Chinese yuan. This coexistence of currencies and settlement rails highlights a practical, if limited, path toward diversified cross-border settlement. It also reflects a broader geopolitical calculation: reducing exposure to Western financial channels while testing a hybrid model that can adapt to sanctions risk, currency volatility, and the speed requirements of modern trade.

Industry observers caution that real-world adoption will hinge on counterparty readiness, custody and settlement infrastructure, and the stability of non-dollar rails under sanctions pressure. Yet the momentum suggests a shift from pure dollar-based settlement toward a blended framework where crypto and digital representations of fiat play a measurable role in energy logistics. As this unfolds, the market will closely watch how counterparties manage price risk, settlement finality, and regulatory compliance in an environment where state actors coordinate policy and markets move quickly.

Gold, central banks and the crypto question: where does Bitcoin stand?

The Fidelity report situates gold’s resilience within a broad narrative about the evolution of digital assets in 2026. While gold’s price has corrected from its peak earlier this year, central banks remain net buyers, a trend that underscores the enduring appeal of gold as a monetary anchor even as crypto narratives press for alternative settlement and store-of-value narratives. The report notes that while gold’s pullback is notable, it aligns with its longer-term role as a safe-haven asset amid global uncertainty. In contrast, Bitcoin’s outperformance narrative has yet to materialize in a way that convinces all investors that BTC is ready to displace traditional reserves on a wide scale.

Gold’s performance and continued central bank demand are broadly aligned with our initial thesis, while the anticipated follow-on outperformance from bitcoin has yet to materialize.

Central-bank behavior remains a key lens through which investors assess Bitcoin’s potential as a reserve-like instrument. Kitco’s coverage of central bank holdings highlighted a shift in some official reserves patterns, including gold overtaking the U.S. dollar in certain stated metrics of global reserve composition. While the exact allocation mix varies by country and policy framework, the underlying takeaway is clear: gold remains a fundamental anchor in the reserve mix even as appetite for new, digital settlement rails grows.

Across the market, the battle lines between fiat-based channels, gold, and crypto-based settlement are drawing sharper distinctions. The question for investors and users is not whether non-dollar rails will exist, but how quickly they will scale, how reliably they can be used for high-value trade, and what regulatory guardrails will emerge to manage risk, privacy, and systemic stability. Fidelity’s framing of “alternative settlement mechanisms” suggests a transitional period in which these rails coexist with the dollar, rather than immediately replacing it.

Sanctions, stability, and the crypto settlement puzzle

Policy actions in the United States underscore the fragility and volatility of crypto flows tied to sanctioned regimes. In April 2026, U.S. authorities moved to freeze and restrict certain stablecoins linked to Iran’s government and the Islamic Revolutionary Guard Corps. The development illustrates the ongoing tension between regulatory enforcement and the unregulated potential of digital assets to bypass traditional financial channels. Against this backdrop, observers note that stablecoins—especially those pegged to the U.S. dollar—face heightened scrutiny, while Bitcoin-dependent toll settlements proceed in parallel in specific corridors where counterparties are willing to navigate a more complex risk environment.

Industry voices, including Sam Lyman of the Bitcoin Policy Institute, have highlighted that stablecoins—though widely used—face clear headwinds in sanctioned contexts. Lyman has pointed out that U.S.-issued stablecoins continue to dominate certain fee streams in oil logistics, even as other rails gain traction in restricted geographies. The divergence between sanctioned, regulated channels and crypto-based settlement underscores a broader policy debate about how to balance financial openness with national security imperatives.

What to watch next in the evolving settlement landscape

The Iran case study raises essential questions for market participants: Will non-dollar rails prove robust enough to support high-frequency, high-value trade? How will counterparties manage custody, compliance, and risk in a mixed-currency settlement regime? And perhaps most importantly, what role will official policy play in shaping the pace and geography of adoption?

As central banks continue to navigate inflation, currency volatility, and geopolitical shifts, the tolerance for diversified settlement tools could expand—especially in energy markets where cost and speed are critical. Fidelity’s analysis points to a longer arc toward more nuanced settlement ecosystems, even if the dollar remains dominant in the near term. Investors and builders should monitor how payment rails evolve in real-world use cases, the regulatory responses that accompany them, and the way macro forces—such as gold’s reserve role and sanctions regimes—interact with crypto adoption at scale.

In the near term, watch for further clarity on how Iranian tolls will be settled in practice, the regulation of cross-border crypto flows in sanctioned contexts, and any new partnerships or infrastructure developments that enable faster, more secure settlement across currencies. The coming quarters will reveal whether these early experiments translate into durable, scalable mechanisms or remain constrained by policy and risk considerations.
