The Ogden rate cut could spark rate increases in wider casualty lines of over 20% in some cases. The renewals on 1 July could be telling with reinsurers needing to boost optimism and cover increased claims costs. A prolonged period of competitive pricing could see those already writing UK EL and public liability lines increase prices. It has been reported that Swiss Re, Munich Re, Everest Re and select Lloyd's carriers would be tempted by this move, although market conditions will still have some impact in the amount prices will rise. The primary UK EL and public liability market is dominated by large composite players, such as Aviva, RSA, Zurich, Allianz and QBE. However it is thought UK EL writers from Lloyd’s will be hit hardest as the margins are so thin any sizeable loss would push a reinsurer to reconsider writing that type of structure at renewal.
