How an insurance industry exits a risk it can no longer price, and what the exit does to everything downstream of it. Opened 2026-10-14 from Sounding the Alarm.
The companion page is the NatCat model layer, which takes the supply side — how the industry’s view of the risk is produced. This page takes what the industry does with that view.
The three steps, in order
The memo states the sequence twice, once as description and once as intent. It is ordered, and the order matters: each step is reached for when the previous one stops working.
- Reprice. “We will simply make policies much more expensive to reflect this elevated physical risk and uncertainty.” Named consequences: inequality of access, cost increases for “critical industries such as farming or shipping”, and a burden transferred to governments and taxpayers.
- Restrict coverage. Exclude elevated perils — the memo’s example is removing wildfire cover from buildings insurance — “as well as other less predictable risks”. The enabling mechanism is stated explicitly: “The nature of insurance being re-negotiated on a 12-month basis allows us to do this without friction.”
- Withdraw. “if there is no way to bring premiums and claims into balance or introduce risk reduction measures we will – for certain geographies and sectors – simply withdraw coverage.”
“This process has already begun and will now accelerate.”
Not framed as a failure. The memo insists the sequence is correct behaviour: “not because of any malice of insurers but because this is how our industry is incentivised to operate if we focus on the short term”, and necessary “to ensure we can continue to pay claims, therefore fulfilling both our fiduciary duty and our role in society”.
⟨Inference: step 2 is the one to watch, and the memo says why without drawing attention to it. The annual renewal cycle means coverage can be narrowed unilaterally, incrementally, and without any event that would make it visible — no cancellation, no refusal, just a changed schedule in a document nobody reads. The memo’s own worry is epistemic rather than commercial: “Ensuring customers really understand that this is happening is critical.” A risk transfer that completes without either party registering it is the condition under which the systemic consequence below builds up unobserved.⟩
The gap is deliberate, and that is the ask
“We are writing this as a call to policymakers and regulators to realise that our models show a protection gap - impending damage that insurers cannot and should not be expected to cover.”
⟨Inference: read as a negotiating position rather than a finding. The memo asks government to accept a boundary that the industry itself is drawing, and asks it in advance of the withdrawal rather than after. “Cannot” is a claim about capital; “should not be expected to” is a claim about mandate, and it is doing the real work. The wiki should record this as the industry’s opening position in a distributive negotiation about who carries uninsurable risk — not as an established fact about insurability. See the discount on the source page.⟩
The transmission to systemic risk
The memo’s second argument, and the one aimed at investors:
- Mortgages. “Insurance is necessary to access a mortgage, allowing providers to manage their own financial exposure. As both domestic and commercial property insurance is limited or withdrawn at a significant scale, we foresee an economic risk that could precede a financial crash in the way that the sub-prime mortgage crisis catalysed the Global Financial Crisis.”
- Inflation, before withdrawal. “if critical industries such as food, property and tourism have to pay more for insurance, there will be an inflationary impact.”
- The industry’s own balance sheet. The timing strategy may fail: “Our ability to perfectly manage timing in a more unpredictable world is not guaranteed”. Addressed to long-term investors, “for whom our corporate plans should provide little reassurance and, in some cases, raise serious alarm”, and specifically to “pension funds looking to provide for their members more than 5 or 10 years into the future”.
⟨Inference: the GFC analogy is the memo’s strongest rhetorical move and its weakest analytical one. Sub-prime transmitted through securitised exposure that was mispriced and widely held; the mechanism here is an asset becoming unmortgageable because it is uninsurable, which is a collateral-value mechanism rather than a contagion mechanism. Both can end in a repricing of property, but they are not the same machine, and the memo supplies no figures for either. Carry it as the authors’ framing, attributed.⟩
Who it falls on
Coastal and mountain communities; communities exposed to flood, wildfire or subsidence; those already struggling to afford cover; farming communities and the agricultural supply chain, flagged as neglected precisely because they “represent a small part of the insurance market”; and nature-dependent industries such as tourism and shipping. Across Europe, North America, Japan “and other regions with currently high levels of insurance coverage”.
Why that last clause matters. ⟨Inference: the memo describes a withdrawal from coverage that currently exists, in rich markets. The coffee MVC describes the opposite boundary — a smallholder financing gap above $200bn/year and an 86% protection gap in Asia-Pacific floods and droughts, i.e. coverage that was never there. These are two ends of one line, and the instrument question differs at each end. Where cover exists and is being withdrawn, the question is what evidence would make it stay. Where it never existed, the question is what evidence would make it start — which is where parametric cover and basis risk sit. Conflating them would be easy and wrong.⟩
Why this is on SINE’s map at all
Insurance was sorted as a meta-lever on the price channel in the 2026-08-15 strategy discussion, on the argument that insurability precedes financeability and that the binding constraint is informational rather than capital. Until this source, that argument rested on a single commissioned research note.
⟨Inference: what this memo adds is not support for the argument but a correction to its optimism. The insurance-first thesis assumes that better information makes risk priceable and therefore insurable. This memo says the industry’s answer to elevated risk is to stop pricing it — and that better information accelerates the exit, because a sharper view of the risk is a sharper reason to withdraw. The memo even says the quiet part: the firms resisting the sharper view are doing so to keep writing business.
So “verified data makes the risk insurable” does not follow. What follows is narrower and still useful: verified data changes where the line is drawn, and moves individual assets across it — a farm with demonstrable adaptation measures priced apart from its postcode. That is a claim about granularity, not about aggregate insurability, and it is the version of the insurance-first thesis this source can carry.⟩
