A New Financial Instrument for Pediatric Oncology

The science exists.
The financing doesn't.

Yellow Bonds convert philanthropic guarantees into revolving research capital · unlocking billions for childhood cancer therapies stranded by market failure, not scientific failure.

It's not a science problem.
It's a financing problem.

The childhood cancer research ecosystem suffers from structural dysfunction · misaligned incentives, fragmented funding, and a market that systematically undervalues the lives of children. Here's what's broken.

6.2M
Preventable Deaths
Between 2020 and 2050, 6.2 million children will die from cancer who could be saved. The Lancet projects scaling proven interventions would produce a net return of $3 for every $1 invested.
80% vs 10%
Global Inequity
In high-income countries, more than 80% of children with cancer are cured. In the world's poorest countries, fewer than 10% survive. Geography, not biology, determines whether a child lives or dies.
30+ yrs
Stagnant Treatment
The same three chemotherapy drugs used in the 1980s remain the standard treatment for osteosarcoma. No new agent has achieved FDA approval in over three decades. Fewer than 30% with metastatic disease survive.
<4%
Funding Inequity
Less than 4% of the National Cancer Institute's budget funds all childhood cancers combined. Only 7 drugs have ever been initially approved by the FDA for a pediatric cancer indication.
−24%
Unfundable by Market Alone
Private-sector pediatric oncology drug development yields expected returns of negative 24%. A JAMA Oncology analysis of 77 potential projects found none could generate positive returns without philanthropic co-investment.
$150M → $3.3B
Philanthropy Can Recycle
The Cystic Fibrosis Foundation invested $150M in venture philanthropy, returned $3.3B, and reinvested the proceeds. Yellow Bonds bring this same structural principle to childhood cancer.

From one-time donation to
revolving research engine

Yellow Bonds transform philanthropic capital from a single-use resource into a perpetual funding mechanism through a six-step cycle.

1

Philanthropic Guarantee Pool

Foundations commit ~$250M to a first-loss guarantee pool held in AAA Treasuries (SPV 1). This capital serves as credit enhancement, absorbing losses so investors are protected if research revenues fall short.

Private Foundations (PRIs) Donor-Advised Funds (DAFs) HNW Philanthropists in Health/Cancer Family Offices (Impact-First) Philanthropic Collaboratives Corporate Foundations (Pharma, Life Sciences) Hospital Foundations (Paediatric Cancer) Research-Ecosystem Philanthropists Impact Investment Intermediaries Philanthropic Advisory Firms
2

Yellow Bond Issuance

Backed by the philanthropic guarantee, SPV 2 issues the $500M Yellow Bond to institutional investors. The credit enhancement targets an investment-grade rating, making this investable for mainstream fixed-income allocators.

Research Portfolio Deployment

Bond proceeds fund a diversified portfolio of pediatric cancer research projects across cancer types, therapeutic mechanisms, and geographies.

Repayment — Three Scenarios

Do portfolio revenues fully repay the Yellow Bond principal?

A — Exact Cover

Revenues repay the bond in full. No guarantee called. Pool rolls into next cycle.

B — Surplus

Revenues exceed bond principal. Excess flows to BCCI for redistribution into the childhood cancer ecosystem.

C — Shortfall

Revenues fall short. Philanthropic guarantee in SPV 1 covers the gap to protect investors.

6

Excess Revenue Distribution

In Scenario B, surplus revenues flow to the Bardo Childhood Cancer Institute (BCCI), which distributes unrestricted funds across the childhood cancer ecosystem.

The Bardo Foundation Partner Non-Profits of the Yellow Bond Ecosystem
Capital Recycling Engine

In Scenarios A and B, the guarantee pool remains intact and rolls forward to back the next Yellow Bond. Over 20 years and 5 issuance cycles (Series A through E), a single $250M commitment generates $2.5B in total research funding — a 10x multiplier.

Six-Layer Risk Mitigation Architecture

LAYER 01
Portfolio Diversification
Projects spanning multiple cancer types, development stages (preclinical through Phase 3), therapeutic mechanisms, and geographies. No single project failure can sink the portfolio.
LAYER 02
14 Independent Revenue Streams
Royalties, milestones, PRVs, diagnostics, therapeutic sales, AI licensing, equity stakes, and 7 more. Revenue is not dependent on any single pathway or mechanism.
LAYER 03
Historical Success Data
Phase 3 pediatric oncology approval rates of 50–70%. $24.6B deployed in royalty financing (2020–2024) with 33% annual growth. Proven asset class with established pricing models.
LAYER 04
Scientific Due Diligence
Expert scientific advisory board with clinical review committees. Market analysis for each funded project. Ongoing monitoring and portfolio rebalancing throughout the bond lifecycle.
LAYER 05
First-Loss Protection
~$250M philanthropic guarantee pool held in AAA Treasuries absorbs all shortfall before any investor loss. This structural feature is what enables the investment-grade rating.
LAYER 06
Independent Oversight
Institutional trustee (BNY Mellon-tier). Big 4 audit firm. Quarterly reporting to all stakeholders. Governance charter with fiduciary duties and no private benefit.

For Policymakers

Between 2020 and 2050, childhood cancer will cost an estimated 318 million life-years. The Lancet projects a net return of $3 for every $1 invested in scaling proven interventions. Yellow Bonds create the financing infrastructure to capture that return.

  • 318 million life-years at stake with a 3:1 economic return on investment (Lancet Oncology Commission)
  • Curative therapies eliminate lifetime treatment costs · one-time investment vs. decades of chronic care spending
  • Complements existing incentive structures (PRVs, Orphan Drug Act) by mobilizing private capital
  • Advance market commitments de-risk the pipeline and signal demand to industry
  • Tax treatment clarity for philanthropic guarantees could unlock billions in dormant foundation capital

Open questions
and honest uncertainties

We believe intellectual honesty is a credential, not a liability. Here's what we're still working through.

Will the portfolio model generate sufficient returns?

Monte Carlo simulations are in progress. The repayment thesis depends on pediatric oncology approval rates holding at historical levels and royalty valuations remaining stable. We're stress-testing downside scenarios.

Can we secure anchor foundation commitments?

The guarantee pool requires 3–5 major foundations to commit $50–100M each. No commitments have been secured yet. This is a chicken-and-egg problem: investors want to see guarantees, foundations want to see investor interest.

Is the credit rating achievable?

Our target investment-grade rating depends on the guarantee structure, portfolio composition, and rating agency appetite for a novel instrument. Preliminary conversations have not yet occurred. This is a key dependency.

How do we ensure Global South access?

Built-in licensing provisions are necessary but not sufficient. The structural barriers to access in low-income countries (regulatory capacity, manufacturing, distribution) extend beyond what a financing mechanism alone can solve.

Disclosure: This study is commissioned by Yellow Bond proponents (The Bardo Foundation). The research methodology is designed to address confirmation bias through independent expert interviews, transparent assumptions, and sensitivity analysis. All limitations are documented.
