FSA managing director John Tiner is to lobby US insurance commissioners to change trust fund requirements on a visit to the States next week.

Tiner is expected to join the campaign on easing requirements for foreign insurers.

Under current rules, overseas insurers without a US licence must place 100% of their outstanding liabilities as collateral.

Tiner is expected to raise the issue at the National Association of Insurance Commissioners (NAIC) meeting in San Diego.
