COVID lockdowns cause dwindling demand, and many supply chains were redirected completely to the account for a sudden strain on medical supplies, and consumer habits were suddenly completely reshaped overnight, the transition away from this sudden change is therefore causing a temporary supply crisis. What we are seeing then is mainly a post-COVID recovery shortage in various forms around the world, which has only been complicated by political reasons in the UK, namely Brexit, which has caused a distinct lack of petrol/gasoline that we are not yet seeing much of elsewhere in the world. An energy crisis is likewise unfolding across Europe as more nations exit COVID lockdowns, China is experiencing similar shortages during this transition that is effecting countries downstream, such as India, and this going so far as to worry US energy insiders who have warned that the US may face winter blackouts in 2021.
In the UK COVID and Brexit have intersected, with so many foreign lorry drivers leaving the country to return to Europe because of these two major issues, Britain is facing such a labour shortage in its haulage sector that fears of fuel shortages mounted to a hysterical run on the fuel pumps. This actually escalated to the point of causing distinct fuel shortages and similar trends are expected to potentially lead to food shortages in the near future. As far as solutions this issue will fix itself as prices stabilise, wages for truck drivers increase and attract more to the field, and the world slowly returns to normal following COVID, but in the meantime we may see more temporary blackouts and shortages.
