Feb 9 (Reuters) - Property and casualty insurer Cincinnati Financial's CINF.O fourth-quarter profit rose on Monday, reflecting higher premiums and investment income.

The results show insurance firms' stability, even as macroeconomic and geopolitical tensions disrupt other businesses.

As consumers and companies grow accustomed to economic uncertainty, spending on policies has remained steady.

Earned premiums rose 10% to $2.59 billion in the reported quarter, the Fairfield, Ohio-based company said.

Investment income jumped 9% to $305 million year-over-year, driven by higher interest payments from its bond portfolio.

The company reported a profit of $676 million, or $4.29 per share, for the three months ended December 31, compared with $405 million, or $2.56 per share, in the fourth quarter of 2024.

The insurer's profit also benefited from a $145 million after-tax investments gain, compared to a $92 million loss last year.

Shares of the company fell more than 2% in after-hours trading on Monday. The stock climbed nearly 13.7% in 2025, lagging the benchmark S&P 500 index .SPX.

Last month, industry bellwether Travelers' TRV.N profit beat Wall Street estimates on the back of stronger underwriting and investment returns.
