Analysts Dan Dolev and Alexander Jenkins at Mizuho pointed to a 7 to 8 percent weekly jump in WTI crude oil prices, driven by U.S. airstrikes on Iran, as the catalyst for their revised outlook. Higher oil prices stoke inflation, which in turn makes the Fed less likely to cut interest rates. For Circle, that dynamic matters enormously: the company earns the bulk of its revenue from interest on U.S. government securities held as reserves backing USDC, its dollar-pegged stablecoin.

In 2024, reserve interest income totaled $1.67 billion, accounting for roughly 99 percent of total revenue. Fewer rate cuts means those reserves keep generating more income for longer.

Mizuho noted that the "right tail risk" of a no-rate-cut scenario in 2026 has doubled, per CME FedWatch data, and that reduced expectations for rate reductions add approximately 1 to 2 percent to Circle's revenue forecasts for 2026 and 2027.

The Fed currently holds its benchmark rate in a 3.5 to 3.75 percent range after three cuts in late 2025. The analysts also flagged a longer-term risk: commoditization of the stablecoin market could compress Circle's revenue growth even if the near-term rate picture looks favorable. "Shifting Fed expectations may matter more for Circle's valuation multiple than for near-term revenue," as The Block characterized the note's broader takeaway.

The Mizuho note follows a strong earnings report Circle released on February 25, 2026. The company posted fourth-quarter revenue of $770 million, up 77 percent year over year and above analyst estimates of $754 million. Net profit for the quarter reached $133 million, and earnings per share of $0.43 beat the analyst estimate of $0.25 by $0.18. Full-year 2025 revenue came in at $2.7 billion, a 64 percent increase. USDC's circulating supply reached $75.3 billion at year-end, up 72 percent. On-chain transaction volume processed through USDC hit $11.9 trillion in Q4 alone, a 247 percent jump from the same period a year earlier. Four Wall Street firms raised their price targets after those results: Bernstein ($190, Outperform), Needham ($130), Clear Street ($92, Hold), and Mizuho ($90 at the time).

Despite the recent stock recovery, CRCL remains roughly 76 percent below its all-time high of around $299, reached at its June 2025 IPO peak.

Mizuho has moved steadily in Circle's direction over the past several weeks. In late January, the bank upgraded the stock from "Underperform" to "Neutral" at a $90 target, with Dolev crediting Polymarket, a prediction market platform that settles trades in USDC, as a meaningful growth driver. He now estimates Polymarket's 2026 trading volumes will annualize around $50 billion, which could add more than 25 percent to USDC's market capitalization.

For users outside the United States, the dynamics described in the Mizuho note are not just an equity story. In Sub-Saharan Africa, Nigeria alone processed close to $22 billion in stablecoin transactions between July 2023 and June 2024, representing about 43 percent of all crypto volume across the region. Nigeria, Kenya, and South Africa together account for roughly 12 percent of global USDC peer-to-peer usage, according to Chainalysis. Many of these users engage with USDC primarily as a payments and remittance tool, moving money across borders at a fraction of the cost of traditional remittance services, which carry an average fee of 8.78 percent for transfers into Sub-Saharan Africa, according to TRM Labs.

In South Asia, approximately 5.7 million wallet addresses in India interacted with USDC in 2024, largely tied to freelance and gig economy payments. Pakistan, meanwhile, ranks among the top three countries globally for raw crypto adoption, according to the Chainalysis 2025 Global Crypto Adoption Index, with usage concentrated among unbanked populations for whom dollar-denominated digital payments provide access unavailable through traditional banking. Circle's Payments Network has enrolled 55 institutions and processes approximately $5.7 billion in annualized volume, making it an increasingly important distribution layer for developers and fintech operators across the region.

Circle's GENIUS Act-compliant status and its ongoing transition toward a federally chartered structure, under the U.S. stablecoin law that took effect in July 2025, give USDC a compliance advantage over less-regulated competitors. That matters for developers and fintech companies in markets like Nigeria, India, and Kenya, where regulators have moved toward formal oversight of digital asset platforms. Nigeria's 2025 Investment and Securities Act and Kenya's 2025 Virtual Asset Service Providers Bill both reflect a regulatory philosophy broadly compatible with the GENIUS Act's framework, raising the prospect of greater formal alignment between those markets and USDC's compliance structure.

The near-term rate tailwind is real. Mizuho itself cautions, however, that the gains rest on an unstable foundation: commoditization of the stablecoin market could compress Circle's revenue growth even if rate conditions remain favorable. Market analysts, including those at BeInCrypto, have noted that a sustained oil-driven tightening of financial conditions could weigh on broader crypto market liquidity even as it temporarily boosts Circle's reserve income model. Geopolitical shocks are not a reliable monetary policy signal. Circle's ability to diversify beyond reserve interest income, through products like its Circle Payments Network, StableFX, and tokenized yield instruments, will be the more durable test of whether the company can hold its value as the stablecoin market matures.

"USDC adoption continued to expand globally as more enterprises, developers, and public institutions integrated digital dollars into real-world payments, treasury, and onchain financial workflows," CEO Jeremy Allaire said on the Q4 2025 earnings call.
