Oil prices have seen a relentless rise in recent weeks with much speculation that they will go over $100 a barrel in the near future. The high oil price has seen the average price of petrol go over £1 per litre in the UK, shortages and rationing in Tehran and violence in Yemen. So what is causing oil prices to rise and what impact is this likely to have on the global economy?

The combination of high global demand for milk and variable weather has led to a rapid rise in the price of milk. Cheese is made from milk (sorry to state the obvious!) and so cheese prices have risen to a new high in excess of £2000 per tonne and further price hikes are expected. One conclusion that could be drawn from this is that it is better to have a takeaway pizza now rather that in a month’s time, but what other effects is this price increase for milk likely to have?
