Oct 17 (Reuters) - Travelers Companies ( TRV ) reported

a nearly three-fold jump in third-quarter profit on Thursday, as

higher underwriting gains and investment income more than offset

steep catastrophe losses.

Core income of the company, often seen as a sector

bellwether as it typically reports results before peers, rose to

$1.22 billion, or $5.24 per share, in the three months ended

Sept. 30, from $454 million, or $1.95 per share, a year earlier.

Individuals and businesses are spending more on insurance,

allowing insurers to attract and retain clients despite higher

prices for some policies such as auto and property.

Travelers' net written premiums rose 8% in the quarter from

a year earlier, as all its units grew, the company said.

Underwriting gains climbed to $685 million compared with a

loss of $136 million a year earlier, while net investment income

rose nearly 18%, thanks to strong fixed income returns and

growth in fixed maturity investments.

A steady U.S. economy and bets of more interest-rate cuts

have helped fuel activity across U.S. equity markets. The

euphoria has also spread to other asset classes, bolstering

gains across investment portfolios.

Catastrophe losses, net of reinsurance, rose to $939

million for Travelers from $850 million a year earlier, due to

the impact of Hurricane Helene and severe wind and hail storms

in the United States.

The losses refer to a significant financial hit that

insurers incur due to large-scale natural or man-made disasters.

The United States grappled with multiple major hurricanes in

2024, including Hurricane Debby that struck Florida in August,

Francine that made landfall in Louisiana in September, and more

recently, Helene and Milton that hit Florida.

Travelers' underlying combined ratio improved to 85.6%,

compared with 90.6% a year earlier. A ratio below 100% means the

insurer earned more in premiums than it paid in claims.
