Oil prices hovering around $114 a barrel are raising fresh concerns about the cost of diesel, with motorists and businesses facing the prospect of further increases in the days ahead.
The rise in crude oil prices reflects renewed worries about global supplies, including disruption to production and continuing geopolitical tensions. If oil remains at these levels or moves towards $120 a barrel, the pressure on fuel prices is likely to intensify.
However, higher oil prices do not translate immediately into higher prices at the pump. Wholesale diesel prices, the pound's value against the US dollar, refinery costs and the availability of supplies all influence what motorists eventually pay. Retail prices can take several days to reflect changes in the market.
Diesel is particularly important to the wider economy. Hauliers, farmers, construction firms and delivery businesses depend heavily on it, and sustained increases can feed through into the prices of food, building materials and everyday goods.
For motorists, the difference is already significant. At £1.99 a litre, filling a 50-litre tank costs £99.50. A rise to £2.09 would add another £5 to the same fill.
The Highlands faces particular challenges because many residents and businesses have little alternative to road transport. Longer delivery journeys and limited public transport options can make rising fuel costs especially difficult to absorb.
Over the next few days, much will depend on whether oil remains above $110 a barrel or climbs further. A move towards $120 would increase the risk of additional pressure on diesel prices, while an easing of supply fears could bring some relief.
There is no certainty that diesel will reach a particular price by a given date. But with crude oil elevated, the immediate balance of risks points towards continued pressure on fuel costs.
For households and businesses already managing tight budgets, another sustained rise would be unwelcome news.
