But its not about how much we personally import from the Gulf - its about the world supply markets. If the countries that buy their oil from the Gulf can't get the supplies they need, they will look to other markets to fulfill their needs, including Norway, the US, Libya and Nigeria.
We may not get the immediate shortages, but they will come if this carries on much longer - and it will take a while to get anywhere near back to normal because once those countries that are affected switch their supply chains, they won't be in a rush to go back to their old ones and risk future instability.
The impact of the damage on processing and storing facilities across the Gulf is also massive - even if this ends in the next couple of weeks - which is looking increasingly unlikely, there is going to be an impact on supplies for years to come.
Hopefully it won't become the apocalyptic nightmare of famines that are predicted in the article someone linked above (although that is actually a very well researched piece), or even rations.
However, it is highly likely that we will see continuing price rises and potentially as a result, will have to make some fairly serious lifestyle changes compared to what we have become used to as a society over the past 40 years, and the past 10 years in particular. I'm not talking on an individual level, but a macro level.
I think we are going to have to very quickly get used to seeing less out of season product availability and also imported fresh foods - especially where production depends on hot houses, we will have to give up our reliability on 'just in time' production and households will have to give up their love of next day delivery for every little thing (and I say that as someone who definitely overuses their Amazon Prime subscription).
Panic buying is stupid, but it is eminently sensible to make sure you have a store cupboard of key supplies and ingredients which you keep topped up and have to hand back up plans for meals a recipes which don't include ingredients that may become hard to get.
I think it is also advisable to keep some cash in the house - if this thing does escalate, one of the impacts is likely to be an uptick in cyber attacks - remember how everything fell apart when the Cloudflare update took out supermarket payment machines for a few hours and bank payments were delayed - imagine that happening for a couple of days!
