Companies are clamoring for some kind of insurance protection in case Greece leaves the euro and sticks them with devalued drachmas, but brokers say the uncertainty around Sunday's election has made that coverage unavailable of
late - and it may not be obtainable any time soon, either.

With the outcome so difficult to forecast, most insurers are unwilling to offer coverage to protect against being stuck with a currency that cannot be converted, brokers said.

"In this business, when there is an election, it's very standard for underwriters to sit back and say 'let's wait and see what happens,'" said Corina Monaghan, vice president of political risk for Aon Risk Solutions.
