Traditional finance is increasingly embracing stablecoins, and the market continues to grow steadily. With advantages such as speed, near-zero cost, and programmability, stablecoins have emerged as one of the most promising building blocks for global financial technology. However, this shift in technical paradigms also brings profound changes to commercial operations—and introduces a new class of risks. A “self-custodial” model based on digital bearer assets, rather than ledger-based deposits, is fundamentally different from the centuries-old banking system.
So, how should entrepreneurs, regulators, and financial institutions navigate the monetary structural and policy-level challenges of this transition? In this piece, we explore three core issues and practical solutions that builders—whether startups or incumbents—can focus on today:
-
Monetary Singleness
-
USD Stablecoins in Non-Dollar Economies
-
Treasuries as Collateral and Their Impact on Monetary Design
1. The Challenge of Monetary Singleness and Unified Currency Systems
Monetary singleness means all forms of money—regardless of issuer or custody method—should be exchangeable at face value (1:1), usable for payments, pricing, and contracts. In practice, this means that a dollar held at JPMorgan, Wells Fargo, Venmo, or in a stablecoin like USDC should always be redeemable at par. While asset management practices and regulatory standings differ across issuers, this 1:1 parity is a pillar of the U.S. banking system’s evolution.
Central banks, economists, and regulators value monetary singleness because it simplifies transactions, governance, planning, accounting, pricing, payments, and security. Today, businesses and individuals take this uniformity for granted.
But stablecoins still fall short. Their limited integration with traditional infrastructure means that if an enterprise wants to redeem, say, $5 million in stablecoins via an AMM, liquidity slippage may prevent them from receiving the full value, potentially triggering market volatility. Unless stablecoins become part of a unified monetary system, their utility will remain constrained.
Currently, redemption mechanisms are fragmented:
-
Issuers like Circle and Tether offer direct redemption primarily to institutional or verified users (e.g., Circle Mint, or Tether’s >$100k direct redemptions).
-
DeFi protocols like MakerDAO rely on Peg Stability Modules (PSMs) to facilitate swaps between DAI and other stablecoins.
While effective, these solutions are limited in scope and require custom integrations. Without direct access, users rely on market liquidity rather than guaranteed face-value settlement.
Even protocols promising tight spreads (e.g., 1 USDC = 1 DAI with a 1 bps spread) depend on liquidity depth, balance sheet capacity, and operational ability.
CBDCs could theoretically provide a unified currency, but concerns about privacy, surveillance, constrained money supply, and slower innovation make alternatives more appealing.
To make stablecoins “true money,” the core challenge is ensuring seamless exchangeability and parity with bank deposits, fintech balances, and cash.
This opens up opportunities such as:
-
Universal mint/redeem access: Collaborate with banks, fintechs, and infrastructure providers to make stablecoin issuance and redemption indistinguishable from fiat.
-
Stablecoin Clearinghouses: Build decentralized clearing systems akin to ACH or Visa to enable real-time, frictionless 1:1 conversions.
-
Collateral Abstraction Layers: Shift redemption logic to tokenized collateral pools (e.g., tokenized deposits or Treasuries), enabling flexible market strategies for issuers while ensuring liquidity for users.
-
Optimized trading UX: Use intent-based execution, account abstraction, and on-chain bridges to route optimal paths and minimize slippage—while abstracting complexity for users.
2. USD Stablecoins, Monetary Policy, and Capital Controls
Stablecoins, particularly those denominated in USD, serve as a savings tool and global payment rail in high-inflation or capital-restricted countries. Businesses use USD as a universal accounting unit, and the demand for a stable, globally accepted medium of exchange remains massive—especially when cross-border remittance fees can reach 13%, and 1.4 billion people remain underbanked.
However, the widespread use of USD stablecoins may undermine the monetary sovereignty of other nations. The root challenge is the Impossible Trinity in economics: no country can simultaneously maintain free capital flow, fixed exchange rates, and independent monetary policy.
P2P decentralized transfers challenge all three pillars:
-
Circumventing capital controls
-
Dollarization reducing domestic policy tools
-
Undermining banking channels that transmit local policies
Still, stablecoins offer benefits: programmable, cost-effective dollars can accelerate trade and remittances, especially when governments can regulate access points (e.g., taxation, compliance for local custodians).
To coexist with local systems, entrepreneurs must design compliance-ready integrations:
-
Localized USD Stablecoin On/Off Ramps: Allow opt-in, small-scale exchanges with clear oversight, avoiding direct shocks to domestic currency systems.
-
Local Currency Stablecoins as FX Bridges: Develop deeply integrated local stablecoins backed by neutral collateral layers (e.g., tokenized Treasuries) to serve as FX conduits.
-
On-chain FX Markets: Build AMMs or aggregators matching stablecoin and fiat liquidity. Require interest-bearing reserves to support leveraged strategies.
-
Compliant cash-in/cash-out networks: Compete with legacy remittance systems (e.g., Western Union) by incentivizing local agents to support cash–crypto conversions.
-
Compliance-first design: Leverage stablecoins' programmability to create transparent, auditable fund flows, reducing AML, tax, and fraud risks.
3. Treasury-Backed Stablecoins: Boon or Bottleneck?
Stablecoins’ success comes from instant settlement, composability, and global accessibility—not from being backed by Treasuries. Fiat-reserve stablecoins took off because they were easier to understand, manage, and regulate. Users trust them due to practical utility and confidence, not collateral type.
Still, if fiat-reserve stablecoins grow 10x (e.g., from $262B to $2T), and regulators mandate short-term Treasury backing, the effects on markets and monetary creation could be profound.
1. Treasury Market Concentration
If $2T of stablecoins hold Treasuries, issuers would own ~1/3 of the $7.6T T-bill market—on par with money market funds. This could drive down yields, crowd out other buyers, and limit collateral availability in repo markets. Treasury expansion (e.g., doubling T-bill supply) may become necessary.
2. Narrow Banking Concerns
Fiat-backed stablecoins resemble narrow banks: 100% reserves, no lending. While low-risk, they hinder credit creation—unlike traditional banks which lend against deposits. A 10x stablecoin growth could shrink banks' funding base, pushing them toward more expensive wholesale funding or reducing lending.
3. Alternative Design Paths
Stablecoins can evolve without relying solely on Treasuries:
-
Tokenized deposits: Represent bank liabilities on-chain, preserving the fractional reserve model while enabling programmability and speed.
-
Diversified collateral: Include municipal bonds, high-grade commercial paper, MBS, and RWAs to reduce reliance on Treasuries and broaden credit access.
-
On-chain liquidity tools: Build mechanisms like on-chain repos, tri-party facilities, or CDP vaults to reinject idle reserves into lending.
This is not a concession to banks—but a recognition that economic vibrancy depends on accessible credit. Stability-focused stablecoins that support lending, velocity, and composability will drive the next financial leap.
Conclusion
The path to turning stablecoins into real money is complex but full of opportunity. Entrepreneurs and policymakers who understand the nuances—from monetary policy to collateral design—will shape a more open, intelligent, and resilient financial system.
Whether through tokenized deposits, compliance-driven ramps, or diversified collateral models, the next chapter of finance will be built by those who master the details—without losing sight of the bigger picture.
