How low oil prices reflect on insurance portfolio?

I think by applying lower oil prices to the quantity insured will reduce the amount of the insurance policy i.e total sum insured , this will consequently reduces the total corresponding premium which may adversely reflected in the insurance company's portfolio. However in  the other hand a positive effect to insurance portfolio appears in term of reducing responsibility and liability upon the insurance company.

My very best wishes.

Low oil price bring a negative impact on insurance prices, especially on marine insurance since most crude oil is transported through marine vessels, with a high oil prices the price of marine insurance coverage will increase since the value of the transported material is higher. Take on account the area where marine vessels pass and attacks on ships always bring a concern to insurance companies. 

Thank you, brother, for your kind invitation Of course, lower oil prices has a direct impact on the value of insurance policies I apologize if any mistakes Greetings

In fact I don't have a complete picture, oil prices jump to doubled almost for decade only, I think prices back to fair and balanced level.

So how insurance "portfolio" (I hate this word) can reflected by, honestly I don't know !!
