XL's property and casualty operation, XL Insurance Global Risk, has revealed plans to increase its underwriting capacity from to $250m (£148m) from 1 July.
The announcement was made at the AIRMIC annual conference in Manchester.
XL Insurance global risk president and CEO Clive Tobin said: "We want to be able to deploy our capacity to strengthen our ability to lead programmes, offer more depth of choice to clients, and to become a preferred partner.
"As a one-stop shop offering access to sister companies with significant capacity in casualty, D&O, environmental, energy and marine coverages, we believe we are an increasingly attractive market for brokers and risk managers."
Earlier, specialist underwriter Dual International signed a deal with XL London Market (XLLM) for its Lloyd's syndicate 1209 to provide it with 100% capacity.
