MI Volumes Jump 12%, Competitive Pressure Builds

Why It Matters

The data signals intensifying competitive pressure on private MIs from government‑backed FHA insurance and highlights strategic pivots that could reshape market share and profitability.

Key Takeaways

• Private MI volume up 12% year‑over‑year.
• FHA market share rose, MI share declining since 2022.
• MGIC net income fell despite higher new insurance written.
• Radian pivots after Inigo acquisition, exits title business.
• Arch and National MI post record underwriting and book sizes.

Pulse Analysis

The mortgage‑insurance landscape is experiencing a rare upside, with the six active private insurers collectively expanding new‑insurance written by 12% in 2025. The surge was anchored in a steep decline in interest rates that revitalized fourth‑quarter originations, a period that traditionally lags. However, the Federal Housing Administration is capitalizing on the same affordability dynamics, expanding its insurance‑in‑force by 9.4% YoY and eroding private‑MI market share that has been on a downward trend since 2022.

Company‑level results illustrate divergent strategies amid the shifting terrain. MGIC, despite retaining the highest volume, reported a drop in net income to $169.3 million, citing modest loss‑reserve development and a slight uptick in delinquency rates. Radian, after completing its Inigo acquisition, is shedding its real‑estate services and title units, signaling a focused pivot toward data‑driven underwriting. Meanwhile, Arch and National MI posted record underwriting income and historic insurance‑in‑force balances, underscoring that disciplined risk‑adjusted portfolios can still generate strong earnings even as overall market share contracts.

For investors and industry observers, the convergence of rising FHA competition, modest pricing adjustments, and strategic realignments suggests a more contested market ahead. Firms that leverage analytics to source high‑value, low‑risk policies—like Radian’s emerging model—may preserve margins, while those relying on volume alone could face pressure on returns. Monitoring credit‑quality trends, regulatory developments, and the pace of FHA expansion will be critical for forecasting profitability and market dynamics in the private mortgage‑insurance sector.
