Physical Climate Risk for Asset Owners

Last updated: 24 May 2026

Physical climate risk is the financial risk arising from the physical impacts of a changing climate. It splits into acute risks, discrete extreme events such as floods, storms, wildfires and heatwaves, and chronic risks, longer-term shifts such as rising temperatures, drought, water stress and sea-level rise. It reaches portfolios through damage to real assets, disruption to supply chains, lost productivity and rising insurance costs. Because the most exposed assets are fixed in place and long-lived, physical risk is hard to escape simply by moving capital.

At a glance

Definition. The financial risk from the physical effects of climate change, both acute events and chronic shifts.

Why it matters. It threatens the value and insurability of real assets, and as impacts broaden it becomes a system-level drag. See climate change as a systemic risk.

Who uses the term. Real-asset and risk teams, reinsurers, the IPCC, TCFD/ISSB and NGFS, and CIOs.

Related terms. Acute and chronic risk, transition risk, insurability, adaptation, resilience, scenario analysis.

Common misunderstanding. That physical risk is decades away. Some impacts are already material to real assets and insurance today.

What physical climate risk is

Where transition risk is the risk of the economy's response to climate change, physical risk is the risk of the climate change itself. As the IPCC has documented, warming is increasing the frequency and severity of many extreme events and driving sustained shifts in temperature, precipitation and sea level. Each of these has a financial counterpart: damaged buildings, disrupted operations, lower agricultural yields, stressed water supplies, and assets that become uninsurable or unfinanceable.

Acute versus chronic

The standard split, used by the TCFD, is between acute and chronic physical risk. Acute risk comes from specific events, a flood that inundates a warehouse, a hurricane that halts a port, a wildfire that destroys property, causing sudden, visible losses. Chronic risk comes from gradual change, higher average temperatures that cut labour productivity and crop yields, sea-level rise that erodes coastal value, shifting rainfall that stresses water-dependent industries. Acute events grab attention; chronic shifts quietly change the long-run value and viability of assets.

How it reaches a portfolio

Physical risk concentrates in real assets that are fixed in place. Coastal and flood-prone real estate, infrastructure, farmland and forestry sit directly in the path of hazards and cannot relocate. Beyond the assets themselves, the risk propagates through supply chains, through the insurers and reinsurers that cover the damage, and through the public finances of exposed regions. For an owner of real assets in particular, location-level hazard exposure is now a core part of underwriting and valuation.

The insurability problem

A distinctive feature of physical risk is its interaction with insurance. As losses rise, insurers reprice or withdraw cover in the most exposed areas, widening the gap between economic losses and insured losses, often called the protection gap. Uninsurable assets are harder to finance and worth less; rising premiums erode returns even where cover remains. The availability and cost of insurance is therefore an early warning indicator of physical risk repricing, and a channel through which physical risk feeds into asset values well before a disaster strikes.

The modelling challenge

Physical risk is genuinely hard to quantify. It requires combining climate hazard projections, which carry their own uncertainty, with asset-level location data and damage functions, then translating the result into financial impact. Data on asset locations is often incomplete, models disagree, and tail events, the most damaging, are the hardest to estimate. Honest physical-risk assessment therefore reports ranges and assumptions, not false precision, and treats the analysis as decision-support rather than a single number.

How asset owners assess it

Practical assessment proceeds in steps: map the locations of physical assets in the portfolio; overlay hazard data for floods, heat, wildfire, drought and sea-level rise; run climate scenario analysis across warming paths; assess insurability and the cost and feasibility of adaptation; and feed the results into valuation, underwriting and allocation. Adaptation, investing to make assets more resilient, can reduce the risk and is itself an emerging investment theme. The aim is to know where the portfolio is exposed and to be paid for the risk it carries.

Why this matters for universal owners

For a universal owner, physical risk is part of the systemic climate risk it cannot diversify away. Geographic diversification helps with any single hazard, but as physical impacts broaden across regions, the systemic component, the drag of a hotter, more disrupted global economy on aggregate growth and returns, cannot be escaped. This is why universal owners treat physical and transition risk together as one climate problem, and why their response includes not just managing exposure but supporting the mitigation that limits future physical risk.

For investment committees

A committee should ask whether the fund knows the physical-hazard exposure of its real assets at the location level, not just in aggregate, and how that exposure is reflected in valuations and return expectations. It should understand the fund's insurability assumptions, since withdrawn cover can impair value quickly, and whether adaptation is being considered where it is cost-effective. Given model uncertainty, the committee should expect ranges and scenario results rather than spurious single-point estimates, and should treat physical risk as a live, present consideration for real assets, not a distant one.

Common misconceptions

"Physical risk is decades away." Some impacts are already material to real assets and insurance pricing today.

"Only coastal property is exposed." Heat, drought, wildfire and water stress affect inland real estate, farmland, forestry, infrastructure and supply chains too.

"Diversification solves it." Geographic diversification reduces single-hazard exposure but not the systemic drag of broad-based warming.

In plain English

Physical climate risk is the damage from the climate itself, sudden events like floods and storms, and slow shifts like heat, drought and rising seas. It hits things that cannot move, like buildings, farmland and infrastructure, and it pushes up insurance costs or removes cover altogether. It is hard to model precisely, so good analysis gives ranges, maps where assets are exposed, and prices the risk in.

Key takeaways

• Physical climate risk is the financial risk from the changing climate itself.
• It splits into acute events and chronic shifts, both intensifying with warming.
• It concentrates in fixed, long-lived real assets and interacts with insurability.
• It is hard to model; honest assessment reports ranges and assumptions.
• The systemic component cannot be diversified away, which is why universal owners manage it.

Frequently asked questions

What is physical climate risk? The financial risk from the physical impacts of climate change: acute events such as floods and storms, and chronic shifts such as heat, drought and sea-level rise, hitting real assets, supply chains and insurability.

Acute versus chronic? Acute comes from discrete extreme events causing sudden damage; chronic comes from gradual, sustained change eroding value over time.

Which assets are most exposed? Fixed, long-lived real assets in vulnerable locations: coastal and flood-prone property, infrastructure, farmland and forestry, plus connected supply chains and insurers.

Can it be diversified away? Geographic diversification reduces single-hazard exposure, but the systemic drag of broad warming cannot be escaped by a diversified owner.
