Stablecoins, Digital Dollarization, and Financial Self-determination in Kenya

Kenya has quietly become East Africa's largest stablecoin market, with USD-pegged tokens, overwhelmingly USDT and USDC, now carrying billions of dollars in remittances, crossborder trade settlement, and savings that the country's mobile-money rails handle poorly. This paper argues that the architecture Kenyans have defaulted to is neither neutral nor costless: it imposes a dual-layered sovereignty deficit. At the macro scale, the substitution of foreign digital dollars for the shilling ("digital dollarization") erodes the Central Bank of Kenya's monetary transmission, fractures the country's position under the Impossible Trinity, and channels seigniorage to the United States Treasury through the Treasury-bill reserves backing these tokens. At the micro scale, the same instruments expose individual users to extraterritorial surveillance and unilateral, contract-level asset freezes against which they hold no jurisdictional recourse. The paper's central claim is that these are two distinct problems demanding two distinct architectural responses, and that solving either alone leaves the system compromised. Reclaiming monetary sovereignty requires scaling local-currency stablecoins (such as cKES on the Mento protocol) and anchoring continental settlement on-chain via PAPSS; reclaiming individual sovereignty requires zero-knowledge cryptography, ZK-KYC, and decentralized issuance models that remove corporate freezeswitches. True financial self-determination, the paper contends, demands their integration, a local-currency stablecoin issued natively on a privacy-preserving, decentralized ledger. Using Kenya's Virtual Asset Service Providers Act 2025 as the regulatory anchor, the paper maps the institutional roles, legislative amendments, and user-incentive problems such a stack would confront, and argues that stablecoins should be understood not as consumer products but as instruments of digital statecraft. Though framed around Kenya, the dualsovereignty trilemma it identifies generalizes across emerging Sub-Saharan markets.
