Implications for Banks Amidst a Growing Insurance Protection Gap
The Australian Prudential Regulation Authority (APRA) released an Insurance Climate Vulnerability Assessment recently, shedding light on the implications for banks due to an expanding – and potentially vast – insurance protection gap.
Climate Change and Home Insurance
The APRA Assessment serves as a prudential stress test, investigating how climate change could influence home insurance affordability and the insurance protection gap in the coming decades. The APRA study examined how home insurance coverage might decline under two “severe but plausible global climate-related scenarios projected out to 2050: one with higher physical risks from weather-related events and one with greater economic impacts from transitioning to a lower emissions economy.”
Increased Financial Risks
Under both these scenarios, pressures on insurance premiums due to climate change could considerably widen the country’s insurance protection gap, thereby escalating financial risks to the system. Today, APRA estimates that roughly one in seven Australian homes are uninsured.
However, under both stress scenarios, the proportion of uninsured homes could escalate to about one in four homes by 2050. This would mean an additional one million residences without sufficient home insurance.
Banking Industry’s Response
It is within this context that the assessment delves into the banking industry’s understanding – or lack of it – regarding the comprehensiveness of home insurance coverage held by its numerous mortgage holders. An increasing protection gap could amplify credit risk by eroding the financial resilience of mortgage holders, heightening the probability of default, while increased exposure to weather risks may impact collateral values, as explained by APRA.
Several banks have taken measures to better comprehend the magnitude of this risk and improve their ability to gauge the percentage of their mortgage exposures that are uninsured, particularly in high-risk regions.
Challenges for Banks
“While it is standard practice for banks to confirm insurance coverage during the loan application process, it can be challenging for banks to monitor whether borrowers maintain sufficient ongoing insurance coverage,” APRA notes.
The establishment of a centralized insurance register to identify the insurance status of properties could offer greater visibility of the potential credit risk from uninsured mortgages throughout the loan duration. The development of such a register would necessitate collaboration between the insurance and banking sectors, as well as the government.
Considering Non-Insurance Implications
APRA reported that some banks have contemplated the implications of non-insurance on credit risk in their mortgage portfolios. Banks that took part in APRA’s corresponding Banking Climate Vulnerability Assessment in 2022 were asked to predict the potential for credit losses arising from defaults under different climate scenarios, including impacts from uninsured or underinsured mortgages. They may also have considered other factors that could protect their balance sheets from financial loss, such as land value, loan leverage, and household wealth.
In conclusion, the implications for banks from a growing – and potentially vast – insurance protection gap is a critical theme of an Insurance Climate Vulnerability Assessment published by APRA. It underscores the need for banks, insurers, and the government to collaborate in addressing these challenges and mitigating potential risks.
