In this video we look at the economics of the supply crunch affecting many countries and especially the UK.
Keeping up to date with topical economics news stories is a great way of adding application to your exam answers. The supply crunch is one of the biggest stories and issues facing the UK at present.
What is a supply crunch?
A supply crunch describes factors causing a fall in market supply of key components, raw materials and (eventually) finished products at a time when demand is rising. These supply chain problems lead to product shortages, rising costs and an increase in cost-push inflationary pressure in an economy.
What are some of the key causes of the supply crunch?
- Shortages of semi-conductor chips - The global semiconductor chip shortage is holding back manufacturing of products ranging from cars and games consoles to home appliances and toothbrushes
- Cut-backs in natural gas imports - Russia has limited natural gas exports to Europe at a time of growing demand. In Europe, the price spike in natural gas is equivalent to if oil were trading around $200 per barrel.
- HGV driver shortage in many countries - a Road Haulage Association (RHA) survey estimates there is now a shortage of more than 100,000 qualified HGV drivers in the UK.
- Logjams at ports and warehouses - the cost of sending products around the world using container ships has surged. Shipping costs affect manufacturers and retailers alike.
- Shortages of materials and components - supplies of key raw materials such as lithium, magnesium, cardboard are well below demand leading to higher prices and production delays.
- Outward migration of labour from the UK - It is estimated that over one million workers from the EU have left the UK since the start of the pandemic.
Some of the causes of the supply crunch are short-term and perhaps transitory, whereas others point to longer-term causes. This distinction can be a good way of evaluating the macroeconomic impact.
How will the supply crunch affect some of the key macro objectives for the UK?
- Inflation: The supply crunch is causing higher input costs which many businesses will eventually pass on to consumers in higher prices
- Investment: Higher costs threaten to reduce company profits and worsen business confidence which might then hit capital investment
- Consumer spending: If prices are rising faster than wages, then real incomes will drop which might cause a fall in consumer demand
- Trade Balance: The UK is a net importer of many inputs such as natural gas, metals and minerals – which will worse the trade balance
- Economic growth: Persistent supply crunch will cause slower growth
What is the UK government doing to address the issue?
- A three-month visa scheme to cover truck drivers and meat workers
- Some temporary subsidies / emergency loans to help keep fertilizer plants open and secure supplies of CO2
- Temporary extension to the limit on how long drivers may be at the wheel and shortened process to qualify as an HGV driver
- In the medium term, the UK government wants businesses to respond to supply chain challenges by raising wages, improving training and lifting labour productivity
- Increase in the National Living Wage to £9.50 an hour from April 2022
The supply crunch as a structural supply-side issue for the UK economy
- An ageing workforce - the average age of an HGV driver is 55, with just 1% under the age of 25. (Less than one per cent are female)
- Work incentives - in many sectors such as HGV driving and food processing, decreasing relative incomes and poor working conditions have caused people to find alternative jobs including in the gig economy
- Non-tariff trade barriers – since the UK’s exit from the EU, businesses now face extensive customs and regulatory checks, adding cost and complexity to cross-border trade. This is independent of a trade deal.
