In recent months, the convergence of regulatory developments, macroeconomic shifts, and capital flows has reignited global interest in stablecoins. Once seen as mere on-ramps to cryptocurrency trading, stablecoins are now emerging as pivotal components of the digital financial ecosystem. A recent report from Citigroup’s Digital Asset Monthly offers a comprehensive framework for understanding this evolution—examining stablecoin use cases, their relationship with the U.S. dollar’s reserve status, and their potential impact on demand for U.S. Treasury securities.
This analysis goes beyond speculation, touching on ETF inflows, rising decentralized exchange (DEX) volumes, miner hash rate trends, and the growing interplay between traditional finance and blockchain-based markets.
Stablecoins: More Than a Transition Tool—They’re the Dollar of Crypto
If you still view stablecoins as just a "bridge" to buying Bitcoin or other cryptos, it's time to rethink.
According to Citigroup, stablecoins have evolved into the de facto base currency of the digital economy—functionally equivalent to how the U.S. dollar operates in traditional finance. They serve as:
- A unit of account for transactions
- A medium for cross-border payments
- A store of value in high-inflation economies
Over the past six months, total stablecoin market capitalization has rebounded to its highest level since before the U.S. election cycle intensified. Tether (USDT) continues to dominate trading volume, reinforcing its role as the backbone of crypto liquidity.
But what’s more telling is the growing adoption by legacy financial players. Companies like PayPal and Visa are piloting payment systems built on stablecoin rails, signaling institutional validation of their utility beyond speculation.
Even more significantly, in countries like Argentina and Nigeria—where inflation erodes savings and political instability undermines trust in local currencies—stablecoins have become a practical tool for wealth preservation. For millions, they aren’t speculative assets; they’re lifelines.
Are Stablecoins a Net Positive for U.S. Treasuries?
A key piece of U.S. legislation under discussion—the GENIUS Act—could fundamentally reshape how stablecoins interact with government debt. The bill proposes that stablecoin issuers back their tokens entirely with short-term U.S. Treasury bills (T-Bills).
At first glance, this seems like a win for the Treasury market: new sources of demand, enhanced liquidity, and deeper investor diversification.
But Citigroup urges caution.
While it's true that stablecoins could become new buyers of T-Bills, much of this demand may simply represent a relocation of existing holdings—what economists call “money moving from left pocket to right.” Many institutional investors already hold T-Bills through money market funds. If those same funds begin allocating to regulated stablecoins backed by identical assets, the net effect on Treasury demand may be minimal.
Moreover, stablecoin reserves favor short-duration instruments due to their need for high liquidity and low volatility. This means any impact will be concentrated at the front end of the yield curve—primarily 1–3 month T-Bills—with little to no influence on longer-dated yields (e.g., 10-year Treasuries).
So while regulatory tailwinds may boost short-term Treasury demand, they’re unlikely to alter broader interest rate dynamics or ease federal financing pressures in a meaningful way.
The Broader Crypto Revival: Why Activity Precedes Price
The resurgence of stablecoins isn’t happening in isolation. It’s part of a broader reactivation across the crypto ecosystem—a shift best understood through key on-chain and market indicators:
- Bitcoin spot ETFs have drawn over $466 billion in net inflows since January, with an additional $35 billion added in mid-May alone
- Ethereum spot ETFs, live since July 2024, have accumulated $32 billion in assets
- BTC dominance has climbed back to around 63%, indicating renewed confidence in its role as digital gold
- DEX trading volume share has increased meaningfully, reflecting stronger organic liquidity on-chain
- Despite declining staking yields, total value locked (TVL) in DeFi protocols is beginning to rise again
These signals suggest a crucial insight: market activity is returning before price appreciation. That’s a healthier pattern than speculative mania driving volume—it indicates structural rebuilding of trust, infrastructure, and usage.
As Citigroup notes, about 50% of global foreign exchange reserves are still held in U.S. dollars, and 80% of FX transactions involve the greenback. This dominance isn’t because the dollar has a stablecoin; rather, stablecoins are popular because they’re pegged to the dollar.
In other words, stablecoins reflect dollar supremacy—they don’t create it.
Yet early signs point to change. Under the EU’s MiCA regulatory framework, euro-denominated stablecoins are now being developed. Though still small in scale, their emergence marks the first real challenge to dollar-centric digital asset design.
Will they disrupt the status quo? Not anytime soon. But they signal growing appetite for multi-currency digital money infrastructure—a development worth watching closely.
Frequently Asked Questions (FAQ)
Q: What gives stablecoins their value?
A: Most major stablecoins are backed by reserve assets such as cash, cash equivalents, or short-term U.S. Treasuries. Their value is maintained through redemption mechanisms and collateralization, ensuring a 1:1 peg to the underlying fiat currency (usually USD).
Q: Could stablecoins replace traditional bank deposits?
A: Not yet—but they’re moving in that direction. In jurisdictions with weak banking systems or high inflation, people already use stablecoins similarly to checking accounts. Broader adoption would require stronger regulation, consumer protection, and integration with payment networks.
Q: Do stablecoins increase demand for U.S. debt?
A: Indirectly and selectively. If backed by T-Bills per proposed regulations like the GENIUS Act, stablecoins can boost demand for short-term Treasuries. However, this often represents reallocation rather than new capital entering the market.
Q: Are all stablecoins backed by U.S. Treasuries?
A: No. While newer regulated models (like proposed "qualified" stablecoins) aim to use T-Bills exclusively, many existing stablecoins hold a mix of cash, commercial paper, and other liquid assets. Transparency varies significantly across issuers.
Q: How do stablecoins affect monetary policy?
A: Currently, their impact is limited. But if widely adopted for everyday transactions or savings, they could influence money velocity and central bank control over interest rates—potentially prompting responses like central bank digital currencies (CBDCs).
The Real Catalysts: Regulation, Macroeconomics, and Trust
Stablecoins aren’t just technological innovations—they’re institutional experiments in parallel finance. Their growth reflects deeper shifts:
- Regulatory clarity (e.g., GENIUS Act, MiCA) is reducing uncertainty
- Macroeconomic conditions (high rates, geopolitical risk) are increasing demand for dollar liquidity
- User behavior shows growing preference for self-custody and borderless access
The core takeaway? Stablecoins won’t dethrone the dollar—but they may redefine how it circulates globally.
As traditional financial boundaries blur, crypto-native infrastructure offers an alternative track—one where settlement is instant, transparent, and programmable.
And while stablecoins may not revolutionize long-term Treasury markets overnight, they are undeniably reshaping the landscape of digital money.
