The Hardened Economy

Why adaptation is the investment — and why we built the Strategic Resilience Portfolio to capture it.

The global economy is hardening. Not in metaphor — in concrete, recycled steel, switchgear, reinsurance, vaccine platforms, satellite imagery, and water treatment capacity. The 21st century is being physically rebuilt to operate under conditions the 20th century never anticipated, and the capital expenditure required to do that work is structural, multi-decade, and largely independent of what any policymaker says about climate next year.

Mitigation protects the world of 2050. Adaptation protects the capital of today.

That distinction matters more right now than it has at any point in the history of climate finance, because adaptation is no longer a thesis, but rather a budget line. US private manufacturing construction has tripled since 2021. Federal infrastructure commitments under IIJA, IRA, and CHIPS exceed $1.2 trillion. The global reinsurance complex has repriced property-catastrophe risk by more than 35% in three years. Twenty-eight separate billion-dollar climate disasters hit the United States in 2023, a record at the time. Whatever your view of the climate science, the actuaries have already made their decision.

The Energy Addition Mistake

Most of what’s currently sold as “climate resilience” or “infrastructure” investing makes a category error. Open the holdings of the largest US-listed infrastructure ETFs and you will find Enbridge, TC Energy, Williams Companies, ONEOK, Cheniere Energy, Kinder Morgan, Targa Resources. These are pipelines, midstream operators, and LNG export terminals — hydrocarbon infrastructure. In our view, these companies primarily represent exposure to hydrocarbon infrastructure and not direct climate adaptation solutions. [IM1] They are the assets generating the systemic shock the portfolio claims to hedge against.

The industry calls this “Energy Addition” — the notion that you can build a resilience strategy by adding clean energy to fossil fuel exposure rather than substituting one for the other. We reject the premise. You cannot effectively hedge against physical climate volatility by investing in the producers of physical climate volatility. The position is funding the arsonist and insuring the building.

The Strategic Resilience Portfolio (SRP)rejects that compromise entirely. It is fossil-fuel-free and internal-combustion-engine-free by construction. There is no “transition” exception. There is no “energy addition” carve-out. There is no quiet allocation to integrated majors under a sustainability halo. The portfolio invests in the firms whose function is to build, maintain, finance, and protect the physical, biological, and financial infrastructure civilization requires to operate in a 1.5°C-warmer world — and excludes the firms whose function is to expand the system creating the warming.

The Resilience Stack

The Strategic Resilience Portfolio is forty-two global equities organized into thirteen functional layers — what we call the resilience stack. Firm clean baseload power and storage form the foundation. Grid hardening and critical infrastructure cybersecurity protect delivery. Earth observation, satellite communications, and resilience-grade engineering software provide the intelligence layer. Water security, thermal resilience, hardened building materials, food and agriculture adaptation, and biological disease resilience cover the physical and biological needs of populations and supply chains. Climate risk analytics, reinsurance, and resilience project finance cap the stack at the financial layer.

Every layer is essential. The absence of any one produces failure modes in the layers above. A grid that cannot deliver power makes hospitals fail. Water systems that cannot operate make cities uninhabitable. Cybersecurity that fails turns physical infrastructure into a weapon. Reinsurance that misprices risk takes insurance markets out of entire regions — which is already happening in California and Florida. [IM2] The portfolio is built as architecture, not as a list of themes.

One Test, Applied Without Exception

We invest in companies whose function is to build, maintain, finance, or protect resilience infrastructure. We exclude companies whose function is to produce, distribute, or expand the fossil-fuel system in any form. One test, applied uniformly across every layer. It is reviewable and applicable, rather than portfolio construction via case-by-case judgment, and it commits to a floor below which we will not extend our definition of adaptation. That floor is what separates this strategy from the broader complex of products that justify hydrocarbon exposure under a “transition” framing.

A functional test admits Nucor and Commercial Metals because their function is to produce recycled-steel structural resilience hardware. It admits Ecolab because its function is industrial water management. It excludes Generac because its function is fossil-fueled backup. It excludes pipeline construction firms regardless of whether they also build transmission. The test does not bend. The portfolio’s intellectual consistency is its institutional defensibility.

Why You Should Take Note

The investment case for the SRP rests on what the climate is doing, what the insurance industry is pricing, and where the infrastructure capital is flowing — not on what anyone hopes will happen next.

We believe it commands genuine institutional appeal across political alignments. ESG-mandated capital sees authentic climate adaptation: a fossil-fuel-free, actively managed, conviction-weighted portfolio of companies materially advancing physical, biological, and financial resilience. National security and infrastructure capital sees American Strategic Resilience: the same portfolio, weighted toward US recycled-steel production, grid hardening equipment, critical infrastructure cybersecurity, water security, and reinsurance-grade risk pricing. Both readings are accurate. Both are well-supported by the underlying holdings. The bipartisan investment case is built into the portfolio’s architecture, not retrofitted to its marketing.

The Strategic Resilience Portfolio is what we believe institutional capital should own if it takes physical risk seriously. The strategy is constructed. The first separately managed accounts are funded with inaugural clients. Preparatory work for a potential ETF launch is underway. The conversation about adaptation, finally, is happening in the language of capital allocation rather than the language of moral exhortation.

We’d like to have that conversation with you.


The Strategic Resilience Portfolio (“SRP”) is an actively managed investment strategy. There can be no assurance that the strategy will achieve its investment objectives or that any investment will be profitable. All investments involve risk, including the possible loss of principal.
