Underwriting Capacity in 2026: What It Means for Australian Borrowers & Businesses

At its core, underwriting capacity refers to the amount of risk that a lender, insurer, or financial institution is able and willing to take on. It sets the boundaries for how much money can be lent, how much coverage can be offered, and under what terms. Factors influencing underwriting capacity include:

• Available capital: The financial resources a lender or insurer has to back loans or policies.

• Risk appetite: The level of risk an institution is prepared to accept, based on internal policy and market conditions.

• Regulatory requirements: APRA and ASIC regulations determine minimum capital and risk standards.

• Reinsurance arrangements: For insurers, agreements with reinsurers can expand or restrict capacity.

Think of it as the maximum “bandwidth” a financial provider has to absorb losses from defaults or claims. When underwriting capacity tightens, fewer loans are approved and insurance becomes harder to secure or more expensive.

In 2026, several developments are directly influencing underwriting capacity across Australia:

• Capital Adequacy Reforms: APRA’s finalised Basel III updates, taking full effect this year, require banks and insurers to hold more capital against certain risks. This has made some lenders more selective, particularly in commercial lending and for higher-risk borrowers.

• Climate Risk and Insurance: With extreme weather events increasing, insurers’ underwriting capacity in sectors like agriculture and property is being stretched. Some regions—particularly flood-prone areas—have seen reduced coverage limits or higher premiums.

• SME Lending Shifts: As the government’s SME Recovery Loan Scheme wound down at the end of 2024, many small businesses are facing stricter lending criteria, with banks reassessing their underwriting capacity for unsecured business loans.

• Technology-Driven Risk Assessment: Insurtech and fintech firms are leveraging AI and big data to refine risk modelling, allowing some disruptors to expand their underwriting capacity in niche markets.

For example, after a series of major storms in Queensland, several insurers temporarily reduced their underwriting capacity for new home policies in certain postcodes, citing reinsurance cost surges and heightened claim risks. Meanwhile, some challenger banks are using enhanced data analytics to offer personal loans to borrowers previously seen as marginal, effectively increasing their capacity in that segment.

Whether you’re an individual, a homebuyer, or a business owner, underwriting capacity affects your access to finance and insurance. Here’s how:

• Loan Approvals: When lenders’ underwriting capacity tightens, approval rates drop, especially for low-deposit home loans or unsecured personal loans.

• Insurance Coverage: Reduced capacity in certain sectors can mean higher premiums, lower coverage limits, or even non-renewal of policies in high-risk areas.

• Business Growth: For SMEs, available underwriting capacity determines whether you can secure funding for expansion or resilience.

In 2026, the Reserve Bank’s cautious stance and subdued property price growth have led banks to focus capacity on lower-risk, prime borrowers. Insurers, facing mounting reinsurance costs, are prioritising risk mitigation and selective underwriting—meaning more questions, stricter conditions, and sometimes, less choice for consumers.

While you can’t control the risk appetite of financial institutions, you can take steps to improve your options:

• Strengthen your profile: For loans, maintain a strong credit score, consistent income, and a manageable debt-to-income ratio. For insurance, invest in risk mitigation (e.g., home flood-proofing, business continuity plans).

• Shop around: Different lenders and insurers have varying capacities and appetites, especially with the rise of fintech and niche providers.

• Stay informed: Keep an eye on policy changes and market trends—being proactive can help you secure finance or coverage before capacity tightens further.

For example, savvy homebuyers in 2026 are seeking pre-approval and locking in rates early, while businesses are exploring group insurance schemes to access greater underwriting capacity than they might individually.
