Circle Stock Rips to 52-Week High as Iran Oil Shock Turns USDC Into a Rate Play

What Happened

Circle Internet Group has been on a tear since reporting Q4 2025 results on February 26. The initial 29% post-earnings pop was only the beginning. Shares opened Monday, March 3 at $91.50 and closed at $99.63, then gapped up again Tuesday to trade above $105 intraday — a level Circle hadn't seen since its post-IPO honeymoon in late 2025.

The broader crypto equity complex moved in sympathy. Coinbase and MicroStrategy both rallied on the session, buoyed by pro-crypto comments from President Trump and a general risk-on tone across digital asset names. But Circle outperformed the group by a wide margin, and the reason is specific to its business model.

For context, Circle went public on June 5, 2025 at $31 per share, opening at $69. The stock now trades above $105 — roughly 3.4x its IPO price in under a year.

Why It Moved

Two catalysts stacked on top of each other within days, creating the kind of feedback loop that sends stocks vertical.

Earnings momentum. Circle's Q4 numbers were genuinely strong. Revenue hit $770 million, up 77% year-over-year, driven by USDC circulation reaching $75.3 billion (up 72% YoY). EPS came in at $0.43 against a $0.35 consensus. Net income jumped to $133 million from just $4 million in the year-ago quarter. That's not marginal — it's a business that found its groove. CEO Jeremy Allaire used the call to pitch Circle as foundational infrastructure for AI-powered financial systems, adding a narrative kicker on top of the numbers.

The Iran shock. Over the weekend of March 1-2, U.S. and Israeli forces struck Iranian targets, sending oil prices sharply higher. WTI crude jumped roughly 7-8% on supply disruption fears, with Brent hitting $80.25 per barrel. This matters for Circle because the company earns the bulk of its revenue from interest on the $18.8 billion in U.S. Treasury securities it holds as USDC reserves. Higher oil prices stoke inflation fears, which push out rate cut expectations — and within 24 hours of the strikes, the probability of zero Fed rate cuts in 2026 nearly doubled. For a company sitting on nearly $19 billion in T-bills, every basis point of delayed cuts flows directly to the bottom line.

Mizuho analyst Dan Dolev raised his Circle price target to $100 from $90, citing this exact dynamic — though he kept a Neutral rating. Mizuho projects USDC circulation could reach ~$123 billion by 2027, generating roughly $3.7 billion in reserve income and $922 million in EBITDA.

What to Watch

Insider selling is the obvious red flag. Between late February and early March, Circle's C-suite and board sold aggressively: CFO Jeremy Fox-Geen sold 47,908 shares at $90, President Heath Tarbert sold 10,753 shares, and Director Patrick Neville sold 35,000 shares worth $3.15 million. In total, 49 insider sales and zero purchases over the past six months. Most were pre-arranged 10b5-1 plans, but the volume is notable at a time when the stock is making new highs.

The rate narrative cuts both ways. If Middle East tensions de-escalate and oil retreats, the rate-cut repricing unwinds — and so does a chunk of Circle's bull case. USDC's 24.3% share of the stablecoin market is growing, but regulatory frameworks like the CLARITY Act could invite deep-pocketed competitors (think banks) into the stablecoin space, compressing margins over time.

Key levels: the $100 round number is now support after serving as resistance. The previous 52-week high near $104 was breached intraday on March 4. Earnings momentum, geopolitical premium, and short-squeeze dynamics are all live — but so is a stock that's up 60%+ in a week.
