Circle Dethroning Tether: USDC Beats USDT Volumes for the First Time Since 2019

$2.2 trillion in USDC transactions versus $1.3 trillion for Tether so far in 2026. Circle overtakes BlackRock in tokenized treasuries. Bitcoin holds $71K as Kharg Island burns. The Fed meets in four days. Every number in this story is a regime change.

Seven years. That is how long Tether held the volume crown in stablecoins. USDT dominated everything from spot trading to cross-border payments to DeFi liquidity. It became so embedded in crypto infrastructure that "stablecoin" and "Tether" were nearly synonymous in most trading circles.

That era ended this week.

Circle's USDC surpassed Tether's USDT in adjusted transaction volume for the first time since 2019, posting approximately $2.2 trillion in on-chain volume so far in 2026 versus USDT's $1.3 trillion, according to data cited by Mizuho analysts Dan Dolev and Alexander Jenkins on March 13. That gives USDC roughly 64% of adjusted stablecoin volumes - a complete reversal from the prior six years where Tether consistently commanded around 70% share.

The same week, Circle's USYC tokenized Treasury fund overtook BlackRock's BUIDL as the largest product in the tokenized government debt market. The broader tokenized Treasury sector hit a record $11 billion in assets under management, up 27% since January 1. Two milestones, same company, same seven-day window.

Something structural is shifting. This is not a blip.

The Volume Flip: What Actually Happened

To understand the magnitude of the USDC volume surge, you need context on what "adjusted transaction volume" means. Raw on-chain volume includes wash trading, bot loops, and MEV activity that inflates the Tether figure significantly. Adjusted volume strips those out and looks at economically meaningful transfers - payments, settlements, trades, and collateral movements.

On that adjusted basis, USDC's $2.2 trillion versus Tether's $1.3 trillion represents a 64-to-36 volume split - a dramatic inversion. As recently as 2022, USDT commanded roughly 75% of adjusted volume. The shift has been grinding for three years but accelerated sharply in 2025 after two catalysts: Circle's IPO (CRCL now trades on NYSE) and the passage of the GENIUS Act stablecoin framework in Congress.

The GENIUS Act matters more than most people realize. It created a federal licensing path for stablecoin issuers and established reserve requirements that strongly favor dollar-denominated T-bill backing - exactly what Circle does. Tether, domiciled in the British Virgin Islands with reserves that include Bitcoin and corporate paper, operates in a gray zone relative to the new framework.

Mizuho analysts, who raised their Circle price target from $100 to $120 after the volume data dropped, cited "USDC activity trends and use cases like Polymarket or agentic commerce expectations" as key drivers. The agentic commerce line is worth unpacking. AI agents transacting autonomously tend to prefer regulated, transparent stablecoins over offshore ones. USDC's on-chain verifiability and regulatory clarity makes it the default for any institution building automated payment flows.

Circle shares (CRCL) rose 1% to $115.40 on the news and are up approximately 95% from their February lows. That 95% gain in six weeks from a stablecoin issuer - not a crypto casino, an actual regulated payment infrastructure company - is the tell.

Circle Dethroning BlackRock in Tokenized Treasuries

The second major story running parallel to the USDC volume flip is Circle's USYC token overtaking BlackRock's BUIDL fund as the single largest tokenized Treasury product on-chain.

USYC has grown to approximately $2.2 billion in supply, per RWA.xyz data. BlackRock's BUIDL - which was the undisputed leader when it launched in partnership with Securitize in early 2024 and briefly held 46% of the market - now sits at roughly $2.0 billion and has seen its share fall from that 46% peak to approximately 18%.

Circle entered this market in January 2025 when it acquired Hashnote, the issuer of USYC, for $1.3 billion. That acquisition now looks like the move of the year. USYC's supply on BNB Chain alone has ballooned to $1.84 billion after Binance integrated it as off-exchange collateral for institutional derivatives trading in July 2025.

The Binance-USYC-BNB Chain connection is the growth engine. Under Binance's Banking Triparty structure, institutional traders can hold USYC with partner banks or with Ceffu (Binance's institutional custody platform), use it as margin collateral, and earn T-bill yield on what would otherwise be idle cash. The capital efficiency argument is compelling. Instead of posting USDT or cash margin that earns nothing, institutions post USYC that generates yield while staying available as collateral 24/7.

That is the real proposition of tokenized Treasuries and it is landing. The broader market hit $11 billion this week, up from $8.6 billion at the start of the year. Most of that 27% gain came during January's crypto market downturn - investors parking cash in tokenized Treasuries to earn yield while waiting for re-entry opportunities. The product is functioning as intended.

"Tokenized treasuries and repo as collateral is a major emerging use case and we are proud of how quickly this has grown." - Circle CEO Jeremy Allaire, posting on X, March 13, 2026

Allaire is not wrong. What was a niche experiment in 2024 is a $11 billion institutional market two years later, and Circle holds the top spot over the largest asset manager on the planet. That is a sentence that would have seemed absurd 18 months ago.

Bitcoin at $71K - A War Resistance Test

Two weeks into what the IEA has called the largest energy supply disruption in history, bitcoin is trading higher than it did when the Iran war started. At $71,000 on Saturday morning, BTC is up 4.2% on the week. Ether gained 5.5% to $2,090. Solana rose 4.2% to $88. BNB climbed 4.5% to $655. Every major token is green on the seven-day chart despite the conflict intensifying, not de-escalating.

Friday's session showed the market's new pattern in real time. Bitcoin hit $73,838 - a one-month high - before the U.S. announced strikes on Kharg Island, Iran's main crude export hub. The news triggered a 3.5% drop in minutes, pulling BTC back to $71,000. Then it stopped falling. The bounce was immediate.

That price action structure - sell on the headline, hold and recover - has now repeated multiple times since the conflict began. Markets have developed a framework for pricing the war. Strikes happen. Oil spikes. Bitcoin dips. Then it recovers as traders conclude the tail risk is not an extinction event for risk assets. The reflexive sell-the-escalation response has faded.

However, $73,000-$74,000 is now a four-time rejection zone. Bitcoin has hit that range four times in two weeks and failed to close above it each time. That level is where sellers are concentrated. Breaking it requires either a dovish Fed surprise or a geopolitical de-escalation. Neither looks imminent.

The $371 million in liquidations over the past 24 hours captured the two-way violence of Friday's session. Short liquidations hit $207 million - the initial run to $73,800 squeezed bears who had been fading the rally. Then when Kharg headlines dropped, long liquidations hit $163 million as the same traders who had just bought the squeeze got stopped out. Classic two-sided flush.

The Fed Variable - March 17-18 Meeting

Everything in crypto markets for the next five days routes through one event: the Federal Reserve meeting on March 17-18. The decision itself is not in doubt. CME FedWatch prices a 95%+ probability of a hold at the current 3.5%-3.75% target range. Nobody expects a rate change.

What matters is the dot plot and Jerome Powell's press conference. The question every market participant is asking: does oil above $100, the largest energy supply disruption in history, and an ongoing Middle East war change the trajectory of rate cuts?

The stagflation scenario - elevated inflation from energy prices while growth slows from geopolitical uncertainty - is the nightmare for risk assets. If the Fed signals that rate hikes could return to the table, or even that the previously expected 2026 cuts are off, the reaction in equities and crypto will be severe. Bitcoin has spent five months pricing in rate cuts that have repeatedly failed to materialize. Any hint that the cutting cycle is over would force a significant repricing.

On the other hand, Powell's historical instinct has been to look through supply-side inflation shocks. The 2022-2023 rate hike cycle was driven by demand-side inflation - pandemic stimulus flowing into consumption. A war-driven oil spike is different in character. If Powell holds that analytical distinction, he could hold the line on current guidance without escalating the rhetoric.

William Blair analysts writing on March 12 noted that "while recent gains could easily be linked to rising oil prices and a potentially more hawkish Federal Reserve, other factors are likely driving the move" in Circle and crypto-linked equities. They pointed to the resilience of USDC market cap and growing recognition of stablecoin infrastructure as a separate growth story independent of the rate cycle.

That framing is useful. The stablecoin and tokenized Treasury narratives documented above are not purely interest-rate-sensitive plays. They represent structural adoption of blockchain-based financial infrastructure by institutions that need settlement rails, yield, and collateral - regardless of what the Fed does on the policy rate.

The Trump Gala Trade - Whale Makes $2.5M in Hours

The more degenerate corner of the markets produced one of the cleanest insider-timing trades of the week. On Thursday, a crypto wallet that had sat dormant for five months suddenly bought approximately 2.2 million TRUMP tokens worth $7 million from Binance's hot wallet.

The timing was not subtle. The purchases began at 01:49 UTC on March 13 - hours after the official TrumpMeme account announced a second Mar-a-Lago gala and luncheon for April 25, open exclusively to the top 297 TRUMP token holders by time-weighted average balance measured between March 12 and April 10.

TRUMP had been trading near a record low of $2.71 earlier that same Thursday. After the gala announcement and the subsequent whale accumulation, the token spiked to $4.50 - a 66% gain from the trough. The dormant wallet's $7 million position was up approximately $2.47 million on paper within hours, according to Arkham Intelligence on-chain data.

The wallet executed four buys: one single-token test transaction first (a classic "testing the address" move), then two purchases of roughly 1 million tokens each worth $6.23 million combined, followed by a 200,000-token add worth $742,000. This is not a random gambler. This is someone with either advance knowledge or exceptional information discipline who sized their position methodically before a catalyst.

Even after the 60% spike, TRUMP is still down approximately 96% from its January 2025 peak of $74. The token launched in the week of Trump's second inauguration and initially captured enormous retail momentum before collapsing as new memecoins - MELANIA, BARRON - diluted attention and capital. The gala mechanism, which requires holders to maintain large time-weighted positions, is a cynical but effective device to incentivize accumulation ahead of exclusive access events.

The Securities and Exchange Commission has not pursued action on presidential memecoins under the current administration, making TRUMP a legally peculiar but functionally active speculation vehicle. Whether the dormant wallet's timing represents front-running, fundamental conviction, or something more irregular is a question that on-chain analysts are now actively investigating.

Arthur Hayes - Why HYPE Could Hit $150 and What That Means for DeFi

Arthur Hayes made his most detailed case yet for Hyperliquid's HYPE token in an interview with CoinDesk's Jennifer Sanasie on March 13, arguing that strong revenue, genuine trading activity, and disciplined token supply could push the token to new highs. Hayes cited $150 as a target price.

The Hayes thesis has specifics worth dissecting. He sold his firm's HYPE position around $50-$55 ahead of expected token unlock pressure. He turned bullish again after the Hyperliquid team chose not to sell most of their monthly token allocations - a signal of management alignment that Hayes weights heavily. He estimates the platform still generates close to a $1 billion annualized revenue run rate based on 30-day fee data.

The metric Hayes uses to evaluate exchange legitimacy is the ratio of trading volume to open interest. A high ratio indicates wash trading - bots cycling positions to inflate volume without genuine price discovery. A low ratio indicates real traders holding real positions. Hayes says Hyperliquid has the lowest ratio among major perpetual DEX platforms, indicating authentic demand.

The geopolitical angle is real. Hyperliquid's HIP-3 permissionless listing system has expanded trading into oil and equity index proxies. When conflict escalates on a weekend - markets closed, no traditional broker access - traders increasingly use Hyperliquid to position. The Iran-related news on Friday evening was a live test of this thesis. As traditional markets sat dark, on-chain perp volume spiked.

Hayes also flagged Zcash as a developing narrative, citing growing concerns about blockchain surveillance and AI-powered transaction analysis. As AI tools for on-chain tracing become more sophisticated, privacy coin primitives acquire new utility for market participants who need confidential position management. That is a legitimate macro driver that most analysts are underweighting.

On Bitcoin, Hayes reiterated his $250,000 end-of-year target. He has missed earlier targets in this cycle but the structural case - institutional adoption, ETF inflows, post-halving supply compression, and geopolitical flight-to-hard-asset demand - remains intact in his framing.

What the Circle-Tether Regime Change Actually Means

Step back from the data points and look at what this week's developments collectively signal.

The stablecoin market is bifurcating. Tether retains a massive $143 billion market cap advantage and remains dominant in offshore trading, emerging markets, and any context where regulatory compliance is not a primary concern. That market is not going away. It is large, entrenched, and Tether's operating model is extraordinarily profitable - the company generated over $13 billion in profit in 2024 from T-bill yields alone.

But the institutional and regulated layer of the market is now clearly moving toward USDC. Polymarket, the prediction market platform, uses USDC for settlement. Agentic commerce applications defaulting to USDC. Binance using USYC as institutional collateral on BNB Chain. Morgan Stanley's ETF structure routing through Coinbase and BNY Mellon. The plumbing of regulated crypto finance is being built on Circle's rails.

The GENIUS Act framework will accelerate this. When Congress sets federal standards for stablecoin reserves and audit requirements, compliance costs rise sharply for issuers that have historically been opaque. Circle, which has been publishing monthly attestations and pushing for regulatory clarity since 2021, is positioned to benefit from the compliance infrastructure it already built.

Standard Chartered expects the total stablecoin market cap to reach $2 trillion by end of 2028. If that projection holds and the current volume split persists, USDC's market cap would need to grow from $78 billion to somewhere north of $700 billion over three years. That math either means Mizuho's $120 price target for CRCL is deeply undervalued, or the volume advantage does not translate to market cap at that pace.

The tokenized Treasury market is a separate but connected story. At $11 billion, it remains small relative to the $6 trillion U.S. Treasury market. But the growth rate - 27% in less than three months, accelerating during a crypto bear period - indicates the institutional adoption curve is steepening. When the Fed eventually cuts rates and T-bill yields compress, the capital efficiency argument for tokenized Treasuries weakens. Until then, 4%-5% yield accessible 24/7 on-chain with near-instant settlement is a real competitive advantage over traditional money market infrastructure.

What Happens Next

The next 96 hours are a stress test. The Fed meeting opens on Monday March 17. Powell speaks Wednesday March 18. Oil is above $100. Iran has issued conditional escalation threats over energy infrastructure targeting. Bitcoin is stuck below $74K resistance with no technical catalyst to break it.

If the Fed holds guidance steady and Powell avoids any hawkish language on oil-driven inflation, markets will likely rally. The pent-up demand to break $74K is real - bulls have been trying to clear that level for two weeks. A favorable Fed remove that ceiling and the next target is $80K.

If Powell signals concern about oil-driven inflation persistence, or if escalation forces the Strait of Hormuz closure that Trump has warned about, the calculus changes. Bitcoin would likely retest $65K-$67K support. High-beta alts would hit harder. The war premium built into crypto's resilience would get stress-tested at a level it has not faced yet.

The structural stories - USDC dominance, tokenized Treasuries, Hyperliquid's perpetual DEX growth - are not rate-cycle-dependent in the short term. They represent genuine adoption of crypto financial infrastructure by institutions that need functionality. That adoption continues regardless of whether the Fed is hawkish or dovish on Wednesday.

Seven years of Tether dominance ended this week. BlackRock's tokenized Treasury lead evaporated in 60 days. Bitcoin is holding war support levels that would have collapsed it in any prior cycle. The numbers from this week are not noise. They are the new baseline.
