We're marking the start of a brand new segment on CNN International's Quest Means Business, where you, the reader, will have an opportunity to choose the topics that you want discussed.
Richard Quest will be teaming up with CNN's Ali Velshi to answer your questions on topics as diverse as technology, travel, finance, commodities and even pop culture.
Our first topic will be on an issue that is integral to many of our lives - wheat.
Sixty percent of the world relies on wheat as a staple part of their diet and many more consume it on a daily basis. Since mid-June, the price of wheat has surged more than 50 percent on world commodity markets, fuelled by Russia's decision to ban wheat exports after crops were devastated by drought.
The price surge shows that any variance or trouble spot in a large wheat-producing country - Russia is the world's third biggest wheat exporter - can be felt all over the world.
What drives sharp rises in world grain prices? Why is wheat so important? How does a price rise impact our decision to buy a loaf of bread?
Here's your chance to ask us and have your question answered.
