    Regime-Based Dynamic Asset Allocation Using Neural Networks

    This episode discusses a research article that introduces a regime-based dynamic asset allocation strategy that utilizes artificial neural networks (ANN) to solve the complex Merton optimal portfolio problem. By using the VIX index as a barometer to distinguish between "risk-on" and "risk-off" market environments, the authors allow the model to adapt its strategy based on shifting macroeconomic conditions. Unlike traditional methods that require solving difficult partial differential equations, this approach trains an ANN to directly learn optimal feedback functions while respecting real-world diversification constraints. A 35-year backtest conducted from 1990 to 2024 demonstrates that this regime-specific strategy consistently outperforms standard, regime-agnostic models in both average returns and expected utility. The study concludes that incorporating market regimes through deep learning provides a more accessible and effective framework for modern portfolio management.

    Private Credit in 2026: Bigger, Broader, and Riskier?

    This episode charts the profound evolution of private credit from the traditional, unrated, and strictly illiquid middle-market corporate direct lending model into a more liquid, institutionalized, and multi-faceted asset class. A central pillar of this transition is the massive expansion into Asset-Based Finance (ABF) and Private Investment-Grade Credit, which now benefits from formal ratings oversight and multi-agency participation, as well as daily liquid, exchange-traded vehicles like the State Street Public & Private Credit ETF (PRIV) that feature daily pricing and valuations. While direct lending still yields a compelling premium (offering over 200 basis points of excess spread relative to new-issue single-B broadly syndicated loans) this yield is increasingly contested. Rapidly intensifying bank competition has catalyzed a broader "credit convergence," driving a decline in underwriting discipline and a significant migration toward "covenant-lite" structures that depart from the traditional relationship-based, covenant-heavy lending baseline. Underneath this expansion lies a sharp tension between manager optimism and regulatory concern regarding credit deterioration, vehicle liquidity, and systemic stability. On one hand, the sanguine manager perspective emphasizes stable trailing 12-month default rates of 3.5%, non-accruals remaining below their 10-year average, and robust corporate performance where larger borrowers (EBITDA >$100M) exhibit a mere 1.4% covenant default rate. On the other hand, the IMF highlights deep-seated vulnerabilities, pointing out that floating-rate debt has pushed over one-third of comparable borrowers into unsustainable interest coverage ratios (ICR 1) and has driven BDCs' payment-in-kind (PIK) interest share to double since 2019. This friction is compounded by the "retailization" of the asset class into evergreen structures (including retail BDCs, European ELTIFs, and PGIM’s pioneering private credit CIT targeting defined contribution plans) which face acute redemption mismatches, illustrated by Australian superannuation rules allowing clients to switch allocations in just three business days. Finally, the IMF warns of severe systemic risks, such as stale "marked-to-model" valuations that take at least four quarters to reflect economic shocks, layers of hidden leverage across the value chain, and a highly concentrated PE-insurer-pension nexus where private equity firms direct premium cash flows from their captive life insurers into their own private credit funds, leveraging offshore Bermuda reinsurers to exploit regulatory discount rate arbitrage.

    Rigor Over Hype: Classifying the Digital-Asset Ecosystem, with Javier Paz

    Everyone talks about digital assets. Very few can tell you, with rigor, what is actually under the hood. This conversation changes that. Kathryn Wilkens sits down with Javier Paz, founder and CEO of RigorRank and former Director of Data and Analytics for Forbes Digital Assets, where he built the publication's nine-factor ranking of more than 600 crypto exchanges and reported investigative work that traced real financial crime. Javier traces his path from multi-asset markets research to building RigorRank, an institutional intelligence platform that now classifies the digital-asset ecosystem across 21 categories and 400 classification groups. They get specific: why proof of reserves leaves too many questions unanswered, what an eight-month investigation into Binance's BNB token revealed about the gap between narrative and on-chain reality, and why a single company like Coinbase can contain thirty or forty distinct legal entities that each do something different under different licenses and jurisdictions. The heart of the episode is tokenization, and why it is far less simple than the headlines suggest. Using Tesla stock in five different tokenized forms, Javier explains how "tokenized" can mean anything from genuine ownership to a non-transferable IOU with none of the protections investors assume, and why the name on the underlying asset, transferability, and jurisdiction matter enormously. They close on where digital assets fit in an alternatives allocation as Fidelity, BlackRock, and Morgan Stanley move in, and what a graduate student should actually learn to work in this space rigorously. About the guest: Javier Paz is the founder and CEO of RigorRank, an institutional intelligence platform for the digital-asset ecosystem. He spent more than two decades in capital-markets research and served as Director of Data and Analytics for Forbes Digital Assets, where he built the annual ranking of the most trustworthy crypto providers and reported investigative work on financial crime in the industry.

    A New Era of American Crypto Regulation and Clarity

    Part 1 of 3: Digital Asset Classification PODCAST SHOW NOTES This kicks off a three-part series on digital asset classification, following up on what I learned at the Spring Consensus meeting in Miami. The series looks at classification from two angles: the regulators' new framework and the push for U.S. clarity (this episode), and how the securities industry and financial authorities fit digital assets into the existing rules (Part 2). A quick heads-up for regular listeners: Part 2, "Navigating Digital Asset Securities and Regulatory Frameworks," actually aired here last week, so you may have caught it already. Each episode stands on its own and you can listen in any order, but if you want the foundational overview first, this is the place to start. Part 3, my conversation with a guest I met in Miami, is still to come (second week of August 2026). This week In March 2026, the SEC and CFTC issued a joint interpretation that finally gave the digital asset market some long-awaited clarity. The framework sorts crypto into a five-category taxonomy: digital commodities, digital collectibles, digital tools, stablecoins, and digital securities. Most importantly, it clarifies that most crypto assets are not securities, and it explains how an asset can "graduate" out of investment-contract status once it no longer relies on a central issuer. The White House backed the shift, advocating a pro-innovation environment to position the United States as a global leader in blockchain technology. Analysts at Fidelity noted that these clear rules of the road may encourage more institutional investment by removing the legal ambiguity that held firms back. Elsewhere in the series Part 2, Navigating Digital Asset Securities and Regulatory Frameworks (already in the feed, from last week): how FINRA, the SEC, the NCUA, and the industry group SIFMA are integrating digital assets into existing securities rules, from the SEC's Crypto Hub and Blockchain Lab, to credit-union guidance and the GENIUS Act's implications for stablecoins, to SIFMA's case that tokenized securities must keep traditional safeguards. Part 3 (coming soon), my conversation with Javier Paz on RigorRank: a classification framework that maps more than 2,300 issuers, infrastructure providers, and custodians across the global tokenized-securities market.

    The Battle for Crypto-Guardrails

    This episode provides some background for the upcoming discussion with our August guest. It outlines the regulatory landscape and oversight strategies for digital assets and financial technology within the United States. The National Credit Union Administration (NCUA) details its efforts to integrate innovations like stablecoins and blockchain while emphasizing that these assets are not covered by federal share insurance. Concurrently, the Financial Industry Regulatory Authority (FINRA) describes its monitoring of member firms engaged in cryptocurrency activities to ensure compliance with existing securities laws. Both organizations highlight the importance of consumer protection, specifically addressing the risks of financial fraud and the need for rigorous institutional supervision. Furthermore, the documents reference the GENIUS Act, which establishes a formal federal framework for the issuance of payment stablecoins. Together, these sources illustrate a coordinated federal approach to managing the intersection of traditional finance and emerging technologies. Resources   American Bar Association.

    Beyond Standard Deviation

    In this episode we discuss various approaches to measuring investment risk and outline some of the pitfalls of using the traditional standard deviation of returns metric. We also examine a journal article which introduces a novel methodology for measuring portfolio tail risk by integrating multivariate extreme value theory with orthogonalized returns. The author, Miloš Božović, addresses the computational complexity of traditional risk models by using principal component analysis and GARCH filtering to transform correlated assets into independent series. These individual components are then analyzed using the generalized Pareto distribution to provide precise, closed-form estimates for Value at Risk and Expected Shortfall. Empirical testing on U.S. stock data and currency portfolios demonstrates that this approach identifies extreme market co-movements more accurately than standard parametric methods. Ultimately, the research offers a robust framework for financial institutions to manage risk during periods of significant market stress and volatility. Sources Kim, M., & Zhou, A. (2024).
