Cornering the Market: Securing such control of the bid or demand-side of both the derivative and the underlying asset that leads to a dominant position. This position can be exploited to manipulate the price of the derivative and/or the asset. With regards to derivatives, in a corner, a market participant or group of participants accumulates a controlling position in an asset in the cash, derivative and other markets. The market participant or group of participants then requires those holding short positions to settle their obligations under the terms of their contracts, either by making delivery or by purchasing the asset from the manipulator or by offsetting in the derivatives market opposite the manipulator at prices distorted by the manipulators.

In the context of a futures contract and leveraged foreign trading corners or attempts to corner, any commodity which is the subject of a futures contract.
