The Strategic Cost of Treating CBDCs and Stablecoins as Separate Projects

Building isolated CBDC rails while ignoring the $160B+ stablecoin market creates a liquidity moat. This forces users to choose between state-backed and private money, guaranteeing a suboptimal outcome for both.

• Strategic Cost: Forces a zero-sum game for on-chain settlement dominance.
• Missed Synergy: Fails to leverage stablecoins as a liquidity bootstrap for CBDC adoption.

Assuming CBDCs and stablecoins will interoperate via future bridges (e.g., LayerZero, Axelar) ignores the ~$2B+ in hacks and the inherent latency of canonical bridges.

• Technical Debt: Post-hoc integration creates permanent security surface area and ~3-5 second latency.
• First-Principles Flaw: Money should be natively programmable, not retrofitted with bridges.

Ceding the DeFi composability layer to private stablecoins (USDC, DAI) allows them to define the standards for programmable finance. This surrenders monetary policy tools like automated tax collection or real-time subsidy distribution.

• Strategic Loss: Private entities set the rules for composability with Aave, Compound, Uniswap.
• Opportunity Cost: Inability to embed regulatory logic (e.g., travel rule) at the protocol level.

Building isolated CBDC rails forces reliance on slow, expensive bridges like LayerZero or Wormhole for cross-border stablecoin flows. This adds ~$5-50 in fees and ~10-60 minute delays per transaction, making real-time commerce impossible.

• Key Benefit 1: Eliminates bridge risk and latency for public/private settlement.
• Key Benefit 2: Creates a unified liquidity pool for instant FX and cross-border payments.

Separate systems force stablecoin issuers like Circle (USDC) and Tether (USDT) to operate as opaque black boxes, requiring regulators to trust their attestations. A shared, programmable ledger allows for granular, real-time regulatory oversight.

• Key Benefit 1: Enables programmable compliance (e.g., geofencing, velocity limits) at the protocol layer.
• Key Benefit 2: Provides a single source of truth for AML/CFT audits, reducing regulatory overhead by ~70%.

A sovereign CBDC silo competes for liquidity with the $160B+ stablecoin market, creating a winner-take-most dynamic. Integration via a hybrid model (e.g., CBDC as a mint/burn hub for regulated stablecoins) leverages existing network effects.

• Key Benefit 1: Instantly bootstrap CBDC utility with existing DeFi protocols like Aave and Uniswap.
• Key Benefit 2: Prevents capital flight by making the CBDC the most capital-efficient settlement asset on-chain.

Ceding the application layer entirely to private stablecoins allows entities like MakerDAO and Ethena to define the future of programmable money. A composable CBDC standard ensures sovereign monetary policy can be natively integrated into DeFi, RWAs, and intent-based systems like UniswapX.

• Key Benefit 1: Sovereign leverage over monetary policy transmission in decentralized finance.
• Key Benefit 2: Fosters a domestic developer ecosystem building on public-good infrastructure, not private platforms.

Siloed liquidity between CBDC rails and DeFi stablecoins like USDC and DAI creates a $100B+ stranded capital problem. Every separate ledger is a friction tax on the future financial system.

• Key Benefit 1: Unlocks programmable monetary policy across public and private ledgers.
• Key Benefit 2: Prevents the balkanization of global capital, enabling seamless cross-border flows.

Without a shared, programmable compliance layer, every transaction across chains becomes a forensic nightmare. This kills institutional adoption for protocols like Aave and Compound.

• Key Benefit 1: Enables real-time, privacy-preserving AML/CFT checks via zero-knowledge proofs.
• Key Benefit 2: Creates a clear audit trail for regulators without exposing user data to every intermediary.

Assuming traditional RTGS finality is sufficient ignores the atomic composability required for modern finance. A CBDC that can't settle a trade on Uniswap or an Olympus Pro bond in one atomic operation is obsolete.

• Key Benefit 1: Enables complex, cross-chain financial primitives (e.g., flash loans, leveraged vaults) with central bank money.
• Key Benefit 2: Eliminates counter-party risk in DeFi by making central bank liquidity the settlement asset.

Designing for either total anonymity (like Monero) or total transparency (like a public ledger) forces a false choice. This alienates users and invites backlash.

• Key Benefit 1: Implements programmable privacy tiers (e.g., zero-knowproofs for low-value tx, KYC gates for high-value).
• Key Benefit 2: Builds public trust by mathematically proving system integrity without mass surveillance.

CBDCs and algorithmic stablecoins like FRAX both fail if they rely on off-chain price feeds. A manipulated oracle can break pegs and distort interest rates.

• Key Benefit 1: Creates a cryptographically secured, decentralized price discovery mechanism for the native unit of account.
• Key Benefit 2: Hardens the system against the $650M+ oracle manipulation attacks that plague DeFi.

Without a unified liquidity layer, CBDCs and stablecoins compete for market share, increasing volatility and killing network effects. See the UST collapse as a case study in isolated design.

• Key Benefit 1: Establishes a shared liquidity pool accessible to both sovereign and private monetary instruments.
• Key Benefit 2: Dramatically reduces the cost of liquidity provisioning and market making across all assets.
