Cost-Benefit Analysis of Synthetic Nucleic Acid Screening for the UK

Interactive data visualizations based on the CLTR report by Fady, Heron, Bruns & Nelson (December 2025). All values in 2025 GBP, discounted at 3.5% per HM Treasury Green Book. Figures reported as mean [5th percentile, 95th percentile].

Core Cost-Benefit Comparisons

1. Annual Costs and Benefits by Stakeholder

Table 1 — Mandatory screening of all orders >50bp vs voluntary status quo. Values in £ millions.

2. Net Benefit Waterfall

Average annual flows from costs through benefits to net benefit. For every £1 spent, the UK gains £3.50.

3. Discounted Annual Costs and Benefits Over Time (2027–2046)

Figure 2 — Growth driven by expanding synthetic nucleic acid market. Confidence bands show 5th–95th percentile.

Policy Option Comparisons

4. Per-Order Net Benefit by Sequence Length

Table A1 — Marginal net benefit per order for each screening threshold, with 90% confidence intervals.

5. Probability of Net Positive Outcome by Policy

Percentage of Monte Carlo simulations where benefits exceed costs.

6. Average Annual Costs and Benefits by Policy Tier

Table A3 — Average over 2027–2046 for each screening threshold. Values in £ millions.

Risk & Threat Model

7. Expected Annual Loss by Event Type

Annex A3.4 — Monetised expected harm from biological events involving the UK synthesis market. Log scale.

8. Risk Attribution by Sequence Length

Expert biosecurity survey — proportion of risk attributable to each order length category.

9. Risk Reduction Pathway

How baseline pandemic risk is filtered through the UK screening policy to arrive at expected benefit.

Sensitivity Analysis

10. Tornado Diagram — Key Variable Sensitivity

Annex C — Impact on average annual net benefit when each variable moves across its distribution range.

11. Distribution of Net Benefit Outcomes

Monte Carlo simulation results — distribution of annual average net direct benefit to the UK.

Market & Industry Context

12. Order Distribution by Length Category

Annex A3.5 — Proportion of UK orders by base pair length, showing which segments each policy captures.

13. Global Synthetic Nucleic Acid Market Size

Oligo market from $950M (2007) to $3.5–6.6B (2025), with projected growth to 2046.

14. UK Provider IGSC Membership

Of 18 UK-based manufacturers/resellers of nucleic acids, only 4 are IGSC members.

International & Scenarios

15. Domestic-Only vs International Harmonisation

Net benefit to the UK if 5–40% of foreign orders also adopt screening. Values in £ millions per year.

16. International Screening Policy Landscape

Key milestones in global adoption of synthetic nucleic acid screening legislation.

Cost Decomposition

17. Per-Order Cost Breakdown by Component

Tables A1 & annexes — Cost composition per order for each sequence length category. Values in £.

18. Regulatory Productivity Loss Multiplier

Annex A3.5.2 — Indirect costs are 1–3x direct compliance costs due to regulatory burden.
