London, UK — Today, Lewis Jackson Ventures (LJV) announced the publication of the Jackson Liquidity Framework (JLF), a breakthrough model designed to solve a missing component in modern financial system design: how to accurately size liquidity for Automated Market Maker (AMM)–based settlement.
As global markets transition toward CBDCs, tokenised assets, and instant cross-border settlement, the need for prefunded liquidity in AMM pools has rapidly grown. Yet no regulatory framework — including Basel III, BCBS 248, or the CPMI-IOSCO PFMI — defines how much liquidity must be held to guarantee safe, predictable settlement performance.
The Jackson Liquidity Framework fills this gap.
AMMs promise near-instant, automated FX conversion for CBDCs and tokenised deposits, but they introduce complex, nonlinear liquidity behaviour. Factors such as slippage, directional flow imbalance, intraday clustering, and fragmentation make liquidity requirements dramatically more volatile than traditional payment rails.
Until now, institutions lacked a formal, quantitative way to measure and mitigate these risks.
The Jackson Liquidity Framework provides the first unified methodology—combining stochastic modelling, Monte Carlo simulations, and regulatory liquidity logic—specifically for AMM-based corridors.
A reserve-sizing rule combining slippage tolerance, directional-flow Value-at-Risk, intraday liquidity stress, and Basel III liquidity encumbrance considerations.
A solvency-style condition defining the boundary between stable and unstable AMM reserve configurations — critical for risk officers and FMIs.
A 3D landscape illustrating how liquidity demand scales with arrival rates, payment-size volatility, and directional skew. Reveals the nonlinear (and often underestimated) liquidity cost of instant settlement.
A single operational measure of corridor stress, designed for real-time monitoring and supervisory dashboards.
Together, these tools create a complete, institution-ready liquidity framework for tokenised settlement rails.
The whitepaper highlights several findings with major implications for CBDC design and AMM-based financial markets:
These findings demonstrate why AMM-based settlement cannot rely on traditional liquidity heuristics — and why a new model is required.
Alongside the release of the whitepaper, LJV has launched an interactive Jackson Liquidity Simulator, enabling users to:
This simulator provides a hands-on way to experiment with AMM liquidity under real-world parameters.
A J-score Monitoring Dashboard is also in development for FMIs and CBDC pilot teams requiring real-time corridor stress analytics.
“The future financial system needs a new liquidity model.
We’re moving into a world of instant settlement, automated FX, and tokenised assets — but the liquidity rules haven’t caught up.
The Jackson Liquidity Framework is my attempt to contribute something real: a quantitative, regulator-aligned methodology that institutions can use today.”
