A hurricane threatening the first direct hit on the United States in more than a decade could cause insurance losses of $25-30 billion and be the second costliest U.S. hurricane on record for insurers, according to initial industry estimates.
Hurricane Matthew is just off the east coast of Florida near Cape Canaveral, the National Hurricane Center said in an advisory on Friday, after killing at least 339 people in Haiti on its move north through the Caribbean.
Data modeling firm RMS has told clients its initial estimates were a 42 percent chance of a $20 billion insurance loss and a 26 percent chance of a $30 billion loss from the hurricane, a source familiar with the research said.
Ben Brookes, vice president capital markets at RMS told Reuters its guidance to clients was based on a forecast from earlier in the week.
"We have continued to update our guidance as the situation changes," Brookes said, without giving further details.
An estimate from Kinetic Analysis of insured losses of $25 billion would make Matthew "the second most costly hurricane in U.S. history behind Katrina," JPMorgan analysts said in a note late Thursday, referring to the hurricane which hit New Orleans and the surrounding coast in 2005.
Kinetic could not immediately be reached for comment.
Market participants expect these estimates to rise.
"People are looking at this literally every minute and working overnight on it," one trader said.
The average impact to U.S. property and casualty insurers' book value from $10-30 billion of insured losses from the hurricane would equate to around a quarter's worth of earnings, the JPMorgan analysts added.
A $20 billion insured loss would match the insured losses caused by Hurricane Sandy in the northeast of the United States in 2012, which did not make landfall. A loss of this size would lead to "material risks" for Lloyd's of London insurers, analyst Ben Cohen at Canaccord Genuity said in a note on Friday.
Cohen calculated a loss equivalent to Sandy would hit Beazley's earnings by $104 million, Hiscox's by 117 million pounds ($145 million) and Lancashire's by $39 million.
Beazley estimates an $80 billion storm would cause a $200 million loss, a spokesman said, without specifying losses from a smaller disaster.
A Hiscox spokeswoman said it was too early to judge the impact of the hurricane.
A Lancashire spokesman also said it was early days, but the firm was feeling "relatively relaxed" about its losses because it was very lightly exposed to risk in Florida compared with other states in which it offers reinsurance for wind damage.
The hurricane represented a "real test" of reinsurers' exposure, S&P Global said in a report, but it did not see a ratings impact, due to reinsurers' strong capital buffers.
