Oil is closely linked to the economy and so major global events like wars, pandemics and the changing policies of economic giants like China are generally reflected in the ups and downs of crude prices. But the uncertain global economic outlook has thrown a bit of a spanner in the works for forecasters recently.

Of course, no one expects to be able to predict the exact price of oil in advance, but it’s usually easier to anticipate moves in oil prices than it has been in recent months.

Read her take on the three global issues causing this confusion right now.

We also hear the fascinating history of sanitary products, from the 19th-century market for special menstrual clothing to today’s sustainable options. And while a government plan to swap cigarettes for vape kits is designed to help make England smoke-free by 2030, two experts argue it primarily means swapping one risky habit for another.
