The five Caribbean Overseas Territories — Cayman Islands, British Virgin Islands, Turks and Caicos Islands, Anguilla, and Montserrat — are among the most resilience-exposed British communities anywhere in the world. They sit in one of the most meteorologically active ocean basins on Earth, their infrastructure is dependent on supply chains that can be severed in hours, their economies are concentrated in sectors that carry systemic risk well beyond their borders, and their populations are small enough that key person dependency is not an organisational problem but a community one.
I spent six years living and working in the Cayman Islands, from 2008 to 2014. Within months of arriving I experienced two storms that together provided the kind of education no classroom exercise can replicate: a tale of two events that illustrated, from opposite directions, the same core lesson about how threat is perceived, how risk is assessed, and how narrow the margin between preparation and catastrophe can be.
The Hurricane Threat — What the Forecasts Miss
The Atlantic hurricane season runs from June to November. For the Caribbean territories, it defines the operational calendar in a way that has no mainland equivalent. Emergency management authorities begin tracking pre-genesis disturbances weeks before they develop into named storms. Businesses review continuity plans. Individuals stockpile supplies. The rhythm of preparation is so embedded in island life that it becomes, in the best sense, Life as Usual — a continuous operational posture rather than a reactive response.
The problem is not preparedness for the expected. The problem is the gap between what the forecast says and what the storm does.
Hurricane Gustav, in 2008, was first tracked as a potential threat to Cayman. As it developed, it altered course; the threat level reduced, and what followed for the island as a whole was a relatively minor event. Within the company I had just joined, however, the episode was instructive: it exposed weaknesses in the plan, gaps in the preparations, and questions about recovery options that had not been adequately thought through. Not a crisis, but a clear signal of the distance between a plan that looks sound on paper and one that has been tested against reality, however modestly.
Paloma, which followed later that same season, was a different lesson entirely. Where Gustav was initially perceived as a serious threat that diminished before it arrived, Paloma was underestimated as a threat — and the consequences fell unevenly across the islands.
A Hurricane Warning was issued for the Cayman Islands on 6th November 2008, with Paloma at that point a Category 1 storm showing early signs of intensification. Throughout Thursday 6th and into the 7th, NHC forecasts continued to predict a relatively low-intensity storm. The majority of the population was preparing on that basis — taking the storm seriously but not treating it as an existential threat.
What the headline forecasts were not fully capturing was the potential for rapid intensification. Additional meteorological data suggested a different possibility: vorticity maps, steering current analysis, and the specific atmospheric conditions that favour explosive development all pointed toward a more severe outcome than the central forecast. The track was also showing early signs of shifting closer to the island than the primary projection indicated. I was monitoring this data and raised the concern directly with our crisis management team: we should not be planning against the central forecast when the tail risk was significantly more severe and the window for action was narrowing.
The rapid intensification did occur — and at a pace the forecasts had not reflected. Only by 4pm on Friday 7th did the NHC begin to openly report on the intensification, and even then their forecast still suggested a Category 2 storm. In practice, Paloma intensified from Category 1 to Category 4 in sixteen hours, a 45mph increase in sustained wind speed in a single day. The most intense period fell on the Saturday — when the office was closed, adding a further operational dimension to an already rapidly evolving scenario. Paloma reached 145mph as it moved away towards Cuba. The track shift that accompanied the intensification moved the storm's centre east of Grand Cayman; the island was, in a meaningful sense, fortunate. Cayman Brac and Little Cayman were not. Those smaller islands bore the full impact of a storm that the headline forecasts had substantially underestimated.
"Official forecasts represent the most likely scenario, not the full threat envelope. The window between a threat becoming apparent and the window for action closing is shorter than almost anyone expects."
Infrastructure Vulnerability — The Supply Chain Problem
The Caribbean territories share a structural vulnerability that no amount of local preparedness can fully resolve: their supply chains are long, thin, and fragile. Food, fuel, medicine, and construction materials arrive by sea and air from suppliers that may themselves be affected by the same event threatening the island. In a major hurricane scenario, those supply chains do not merely slow down — they stop.
Telecommunications infrastructure presents a particular vulnerability. Terrestrial communications are among the first systems to fail in a major event. Submarine cables, on which the islands depend for internet connectivity and international financial communications, are resilient to moderate events but not to the storm surge and seabed disruption that a direct major hurricane strike can cause. Satellite communications provide a backup, but at reduced capacity and significantly higher cost.
In an island community, communications can be severed in ways that have no mainland equivalent, and the backup arrangements need to be designed into plans rather than assumed. Our business continuity planning included satellite phones specifically to maintain island-to-world communications in scenarios where terrestrial and standard cellular infrastructure had failed. This was not a theoretical contingency. It was an operational necessity that reflected a clear-eyed assessment of what a serious event would actually do to the communications environment.
But the communications vulnerability extends beyond the natural disaster scenario. In a context where geopolitical pressure is applied against British territory interests, the question of how backup communications are provided and routed becomes a strategic question as much as a technical one. Emergency communications that depend on infrastructure passing through a hostile jurisdiction are not genuinely independent. The resilience of communications in a deteriorating geopolitical environment requires the same design discipline as resilience against a hurricane — and it has received far less of it.
The Cayman Islands' dependence on desalination for fresh water places it in a category of vulnerability that has no easy mitigation. There is no aquifer to fall back on and no surface water. An island of approximately 90,000 people that cannot generate its own power cannot desalinate water — and an island that cannot desalinate water faces a timeline measured not in days but in hours.
The Key Person Problem
Small island communities face a resilience challenge that large organisations manage through redundancy and depth of resource: key person dependency. In a community of 90,000 people, the number of individuals with the specific expertise to maintain critical systems — power generation, water treatment, telecommunications infrastructure, financial system operation, emergency medical care — is small. In a major event, some of those people will be managing their own families' safety. Some will have evacuated. Some will be unavailable for reasons that have nothing to do with their professional commitment.
This is not a solvable problem in the conventional sense. What you can do is design systems and plans that minimise dependence on individual availability at the worst possible moment. That design discipline — engineering resilience in rather than staffing it in — is the principle that should govern territory resilience planning but rarely does.
Regional Exercising — What Exists and What Is Missing
Regional multi-hazard exercising does exist. CARIBE WAVE, the annual tsunami preparedness exercise conducted under UNESCO's Intergovernmental Coordination Group, has run since 2011. In March 2026, its fifteenth iteration mobilised over 600,000 registered participants from 44 member states and territories — one of the largest tsunami simulation exercises anywhere in the world. One of its two scenarios was built specifically around a 7.6 magnitude earthquake southwest of the Cayman Islands. British territories including Anguilla, the Cayman Islands, the British Virgin Islands, Montserrat, and Turks and Caicos participate each year.
The exercise works, and it demonstrates that cross-territory, multi-jurisdictional preparedness exercising at scale is achievable. What it also demonstrates is the gap: a regional exercise in which British territories participate but which is not integrated into any UK national resilience framework, not coordinated by any UK resilience body, and not used to generate learning that feeds back into UK national resilience planning. The UK is present in the exercise through its territories. It is absent as a national resilience actor.
Financial Services Concentration Risk
The Cayman Islands is among the world's leading financial centres by the scale of assets it administers. The British Virgin Islands hosts one of the world's largest offshore company registries, with approximately 356,256 active registered companies as at end-2025. The operational disruption of these centres is not merely a local economic problem; it has systemic implications for the global financial system that extend far beyond the Caribbean.
Fund administration requires continuous operation. Investor reporting, NAV calculations, regulatory filings, and transfer agency functions operate on deadlines that do not pause for natural disasters. The Cayman Islands Monetary Authority has operational continuity obligations built into its supervisory framework. Individual firms have their own business continuity obligations. But the underlying systemic question appears not to have been modelled at the systemic level: what happens to the global fund administration ecosystem if Cayman's communications are severed for 72 hours following a direct Category 5 strike?
This is not a hypothetical risk. Hurricane Ivan in 2004 demonstrated what a direct major hurricane strike does to a Caribbean island's operational capacity. The financial services sector has grown enormously since then. The systemic dependencies have deepened. The risk has not diminished — it has increased.
CIMA does impose operational continuity obligations, but they are written for individual firms, not for the financial system those firms collectively constitute. There is no published equivalent to the UK's "important business services" regime, no articulation of sector-wide impact tolerances, and no public evidence of cross-entity dependency mapping. The result is a structural gap: robust continuity expectations for each firm, but no system-level resilience model for a jurisdiction whose infrastructure can be disabled all at once.
"It is a gap that remains largely invisible in London's risk registers — but not in the Caribbean."
