When Insurance Becomes a Threshold: The New Reality of Financing Construction Projects

In the past, construction insurance was viewed as a post-event safety net—a financial tool to cover losses when accidents occurred. But this role is now reversing.

According to Zurich Insurance Group's report, "Beyond 2030: The Future of Construction," insurance availability has become a key variable determining whether large construction projects can secure financing. The report warns that projects unable to obtain adequate insurance coverage may struggle to raise funds from lenders and investors.

Behind this lies a combination of complex risks. The report quantifies the risks facing the construction industry over the next five years, with extreme weather and natural disasters topping the list at 6.2 out of 7, followed by financial market fragility and labor shortages. Kelly Kinzer, Zurich’s Global Head of Construction and Surety, notes that projects are becoming increasingly complex, while delivery environments are more volatile and timelines more compressed. "Insurability has become a critical consideration, because projects that cannot obtain insurance are almost impossible to finance."

This trend is not an isolated phenomenon. Globally, climate change is rewriting the fundamental assumptions of risk assessment. Extreme events once considered "once-in-a-century" now occur with greater frequency within project cycles. Insurers are having to raise premiums, tighten terms, or even exit certain high-risk markets altogether. For investors, insurance is no longer just a cost item but an early signal of a project's resilience.

The report shows that insurers are shifting from passive claims handling to proactive risk identification—getting involved during project planning, site selection, and procurement stages, rather than waiting until after construction begins to assess risk. This upfront "due diligence" function essentially turns insurance into a filter for financing viability. If insurance coverage is unavailable, restricted, or prohibitively expensive, lenders may adjust financing conditions, delay disbursements, or reduce commitments.

This change is particularly profound for the Asia-Pacific region. As one of the most active regions for infrastructure development globally—from Indonesia's capital relocation project to cross-border railways in Southeast Asia—many projects depend on international capital. When an insurance gap appears, it affects not just individual developers but the entire business model of the project. In the ASEAN region, for instance, Zurich previously noted that approximately $165 billion in renewable energy assets are exposed to climate risk, and these assets similarly rely on insurance to attract investment.

Labor shortages are also exacerbating risks. The construction industry has long relied on migrant workers, and post-pandemic labor market volatility has made delays and cost overruns the norm. When actuaries price insurance, they must factor in labor uncertainty, further driving up premiums.

The fragility of financial markets themselves casts another shadow. Interest rate fluctuations, inflationary pressures, and geopolitical tensions add more variables to a project's financial model. As a risk transfer tool, insurance itself is seeing rising costs, creating a negative feedback loop.For urban managers, this trend means a need to rethink the overall logic of infrastructure development. Higher insurance thresholds may encourage stricter siting standards and higher quality design requirements, which in the long run will help enhance the resilience of building assets, but in the short term may drive up development costs and delay project progress.

Investors are also adjusting their strategies. A number of specialized insurance brokers and reinsurance companies have begun developing customized products for climate risks, such as parametric insurance, which triggers automatic payouts based on wind speed, rainfall, and other factors rather than relying on traditional loss assessments. Such innovations have the potential to fill some of the protection gaps, but large-scale application is still some way off.

Ultimately, the real impact of the construction insurance gap is not about how much premiums have increased, but how it changes the structural prerequisites for project financing. When insurance shifts from being a safety net to a threshold, projects that can demonstrate stronger risk management capabilities will gain priority access to capital markets. And those that cannot cross this threshold may remain on the drawing board, no matter how perfect their technical solutions are.
