Investment case and resilience imperative

Data centres are becoming a major infrastructure asset class, and financial institutions are increasing exposure through lending, investing and underwriting. The growth of cloud computing and AI infrastructure presents a financing opportunity. This opportunity is coupled with resilience related risks such as climate exposure, energy constraints and operational disruption that traditional underwriting and valuation frameworks may not capture. For banks, insurers, private credit funds and institutional investors, managing this exposure becomes a matter of importance to protect cash flows, asset value and insurability of the investment. Annual investment in data centres is projected to double from around US $500 billion in 2024 to more than US $1 trillion as early as 2027. A major share of the expansion is moving towards the Asia Pacific, with overall capacity (excluding China), projected to increase from around 9GW, to more than 28GW by 2030.

Climate exposure and systemic risk

Climate risk, however, remains largely absent from many underwriting and valuation frameworks, even though it directly shapes uptime, operating costs, insurance availability and infrastructure reliability over the life of the asset. About 54% of global data center capacity is in markets exposed to chronic climate stress, including extreme heat and drought, which increase cooling costs, reduce efficiency, and put operating margins under pressure. Chronic exposure also varies significantly across major investment markets. Exposure reaches 89% of capacity in APAC, compared with 50% in the Americas and 46% in Europe, the Middle East, and Africa. Major cloud outages can trigger claims across many customers at once, which pushes insurers to treat data centres as a source of systemic risk, rather than a standard property class. As a result, resilience is becoming a credit and valuation consideration, rather than solely an operational concern.                                            

These risks have direct implications for financial performance. Heat stress can increase operating expenditure through higher cooling demand, while water scarcity may constrain operations in certain markets. Extreme weather events can damage critical infrastructure, disrupt revenues and affect asset values. For lenders and investors, these risks ultimately influence debt-service coverage, asset quality and long-term cash flow stability.  

From an underwriting perspective, data centres present a combination of concentration, construction and operational risks. Energy supply is widely flagged as the sector’s biggest long-term bottleneck. Delays in grid interconnection can push back a project’s completion timeline and revenue expectations which remains a gap for a lender, independent of climate risk. Individual assets can represent billions of dollars in value and are often dependent on power availability, network connectivity and stringent uptime requirements. Any disruption can have implications for revenues, compliance requirements and the ability of operators to service debt obligations. Additionally, multiple stakeholders are involved in the development of a data centre, including hyperscalers, developers, utilities, equity investors and lenders, each with different needs in various phases of development. This makes it harder for any single instrument or provider to cover the full range of risks present.

The total insurable values for a single data centre are expected to reach up to US $30 billion per location. Roughly 11,000 data centres are currently in operation globally, representing a total insurable asset base of more than US $2 trillion. Traditional financing and insurance structures were not designed for assets that combine high physical concentration, critical infrastructure status and growing climate exposure. As data centres increase in scale and strategic importance, financial institutions are exploring mechanisms that can transfer, price or reduce resilience-related risks more effectively.

Financing resilience remains challenging because many investments such as redundant power systems, water-efficient cooling, flood protection and enhanced backup capacity require substantial upfront capital, while their benefits are realised primarily through avoided losses over a long and uncertain period. These benefits can be difficult to quantify, may accrue across different stakeholders and are not always reflected in valuations, loan terms or insurance pricing. Limited asset-level data, inconsistent resilience metrics and uncertainty over future climate conditions further constrain lenders’ and investors’ ability to assess whether additional expenditure will materially reduce risk. As a result, otherwise viable resilience measures may struggle to secure dedicated funding or favourable financing terms.

Financial instruments for resilience

Parametric insurance is most relevant for rapid liquidity when climate or infrastructure events disrupt operations. It can address risks such as prolonged grid outages, extreme heat, water stress or other climate-linked events that affect uptime or raise operating costs, even where there is limited or no physical damage. For lenders and investors, a parametric cover in place, may reduce cash-flow disruption, support debt-service capacity and strengthen the resilience profile of the asset.

While dedicated catastrophe bonds for data centres remain largely an emerging concept, they illustrate how capital markets could help absorb risks that may become difficult for insurance balance sheets to carry. For financial institutions, catastrophe bonds and insurance-linked securities offer a potential mechanism for transferring concentrated catastrophe exposure to a broader pool of investors. Data centre catastrophe (cat) bonds and ILS are anticipated to be used to cover peak natural catastrophe risk exposures, such as earthquakes and hurricanes, while ILS capacity is also seen as viable for other exposures including business interruption covers. Insurers aim to issue bonds providing up to US $1 billion in coverage for individuals or groups of data centres. This scale reflects how concentrated the value has become on a single site as facilities have grown from server halls to billion-dollar campuses.

For lenders, resilience investments can be viewed as credit enhancements. Measures that reduce outage risk, strengthen flood protection or improve energy redundancy may help preserve asset performance during stress events, supporting stronger cash flow predictability over the life of the financing. Resilience bonds take this a step further by pricing the value of resilience investment directly into the cost of capital. This involves a contract where an issuer raises capital from investors, with the use of proceeds directed towards specific projects aimed at enhancing physical, social, or economic resilience. It fundamentally shifts the financial focus from reacting to disasters towards proactively investing in preparedness.

More broadly, resilience can be supported through outcome-based or results-based finance, where financing terms are linked to measurable performance outcomes. Relevant outcomes could include uptime performance, reductions in water-use intensity, improvements in cooling efficiency, greater power redundancy or increased use of low-carbon backup power. This approach connects the cost or availability of capital to the resilience characteristics that matter for lenders, insurers and investors. Sustainability-linked bonds are one way to structure this approach, as their coupon or margin can increase or decrease depending on whether agreed key performance indicators are met. However, the important point is that resilience can be measured, priced and rewarded through financing mechanisms.

Securitisation addresses a different challenge from resilience bonds or parametric insurance as it helps financial institutions finance and manage exposure. For lenders and institutional investors, securitised data centre transactions can convert long-term contracted lease income into rated debt instruments, providing pathways to assess tenant quality, cash-flow stability and asset-level risk. Its relevance to resilience is indirect but increasingly important. If climate exposure, power redundancy, cooling efficiency and water availability begin to affect operating performance, these characteristics may also influence the overall rating and pricing of the portfolio. In this sense, securitisation can become a channel through which financial institutions price resilience into data centre financing.

As the sector matures, resilience and sustainability are becoming inseparable considerations. Facilities that are sited with climate exposure in mind, cooled efficiently, and financed through instruments that reward resilience are better placed to operate reliably over their full lifespan. For financial institutions and developers alike, the opportunity lies in treating resilience as a measurable and financeable characteristic of the asset. Treat the asset as one that can attract capital on better terms while supporting a more climate resilient digital economy.
