Summary

The September 30, 2025 episode of New Foundations features Richard Byworth outlining how ETF-enabled collateral and sub-1× MNAV pricing shape Bitcoin-exposed equities. He explains why selective Bitcoin sales for buybacks can be accretive at deep discounts and how shorts, primary allocations, and trading frictions sustain mispricing. The discussion details consolidation pathways and the role of interest-rate cycles in amplifying or damping supply pressure.

Take-Home Messages

1. ETF Collateral Channels: Lenders accepting ETF shares for LTV change institutional participation and risk profiles.
2. Discount-Arbitrage Playbooks: Selective Bitcoin sales can fund accretive buybacks that raise Bitcoin-per-share at sub-1× MNAV.
3. Microstructure Matters: Short interest, placement decisions, and access frictions can prolong MNAV gaps.
4. All-Stock M&A: Consolidation can re-rate stacks by improving liquidity, governance, and index eligibility.
5. Rate-Cycle Sensitivity: Falling funding costs may reduce spot selling via collateralized borrowing, but leverage raises drawdown risk.

Overview

Richard Byworth argues that U.S. spot ETFs altered more than access; they created collateral pipes that lenders accept, enabling loan-to-value against ETF shares. He cites an example of a large IBIT position reportedly justified by its borrowing utility, not just price exposure. In his account, collateral access sits beside inflows as a primary driver of institutional behavior.

He focuses on public companies with Bitcoin treasuries trading below their mark-to-net-asset-value and links discounts to weak sentiment and capital misallocation. Byworth contends that selling a measured slice of Bitcoin to finance buybacks can increase Bitcoin-per-share when discounts are steep. He ties persistent gaps to short-seller positioning, book allocations, and episodic brokerage constraints that throttle demand.

On market structure, Byworth presents all-stock acquisitions as a rational response to mispricing and points to recent deals as templates. He argues that acquirers can justify paying near or above MNAV when liquidity, governance, or index eligibility improves post-merger. In his telling, consolidation can compress discounts and reframe how stacks are managed.

Macro policy forms the backdrop for treasury behavior and on-exchange supply. Byworth expects lower policy rates to cut borrowing costs against ETF shares and reduce the need to sell spot to raise cash. He warns that leverage amplifies both directions and requires explicit guardrails to survive drawdowns.

Stakeholder Perspectives

1. Public-Company Boards: Seek rules-based triggers for buybacks and debt sizing to balance discount closure with long-term stack optionality.
2. Institutional Lenders: Expand collateral programs on ETF shares while tightening liquidation protocols to contain gap risk.
3. Index and ETF Gatekeepers: Evaluate eligibility and float improvements from consolidation that could drive durable re-ratings.
4. Short Sellers and Market Makers: Exploit borrow and access frictions but monitor squeeze risk as capital-allocation policies harden.
5. Regulators and Exchanges: Scrutinize disclosure on MNAV, leverage, and trading access to support fair and orderly markets.

Implications and Future Outlook

If funding costs fall, collateralized borrowing against ETF shares could displace some spot sales, marginally tightening liquid supply. Issuers with pre-committed MNAV bands for buybacks may close discounts faster and stabilize investor bases. The combination of cheaper credit and clearer playbooks could concentrate flows into better-governed vehicles.

Consolidation will likely continue where operating assets and stacks trade below combined value, using all-stock deals to capture scale and improve float. Post-deal governance, index inclusion prospects, and disclosure discipline will determine whether re-ratings persist. Poor integration or opaque policies could erase any initial premium.

Risk management will define survivorship through full Bitcoin cycles. Boards that set leverage caps, term out liabilities, and publish stress-test thresholds will endure deeper drawdowns. Those that chase momentum with short-dated debt or ad-hoc buybacks risk insolvency when volatility snaps back.

Some Key Information Gaps

1. Which buyback policies best close sub-1× MNAV gaps while preserving long-term stack optionality? Clear playbooks can align governance with valuation repair without sacrificing strategic reserves.
2. To what extent do rate cuts measurably reduce on-exchange sell pressure via collateralized borrowing? Separating funding-cost effects from price moves is essential for policy-relevant supply analysis.
3. What leverage guidelines minimize insolvency risk for corporate treasuries across full Bitcoin cycles? Tested caps and term structures can prevent forced liquidations when volatility spikes.
4. Under what conditions does all-stock M&A deliver durable MNAV re-rating rather than transient relief? Identifying integration, float, and index thresholds can guide deal structuring.
5. What educational interventions convert gold-only allocators who already accept debasement logic? Targeted credibility signals may accelerate first allocations and broaden the investor base.

Broader Implications for Bitcoin

Collateral Infrastructure as Policy Variable

ETF-enabled collateral turns market plumbing into a macro lever, shaping how quickly liquidity transmits into Bitcoin holdings. As lenders formalize LTV programs, small changes in haircuts or eligibility can swing spot supply by meaningful increments. Policymakers and exchanges may need disclosure norms that surface collateral usage to avoid hidden procyclicality.

Governance Standards for Asset-Backed Equities

Persistent MNAV gaps indicate weak or inconsistent capital-allocation rules across issuers. Codified bands for buybacks, issuance, and debt sizing could become baseline governance expectations for Bitcoin-exposed equities. Over time, indices and large allocators may reward rule-of-law style treasuries with lower discounts and cheaper capital.

Consolidation and Index Pathways

All-stock M&A can transform float, liquidity, and governance in ways that trigger index eligibility and passive flows. If this dynamic scales, benchmarks may indirectly arbitrate treasury discipline across the sector. The result could be fewer, larger vehicles with standardized disclosures and tighter MNAV tracking.

Rate-Cycle Amplifiers and Safety Valves

When policy rates fall, collateral channels can suppress spot selling, but they also embed leverage at the system edge. Stress-tested margin frameworks and pre-arranged liquidity backstops can act as safety valves during sharp drawdowns. Cross-sector coordination among lenders, exchanges, and issuers will matter as much as any single firm’s policy.

Investor Education as Market Microstructure

Allocator beliefs about buybacks, MNAV math, and leverage safety directly influence discount persistence. Standardized dashboards that report Bitcoin-per-share, discount bands, and policy triggers can compress the learning curve. As understanding improves, price discovery should rely less on rumor and more on transparent treasury mechanics.
