Pulpex, the joint venture between OM London Exchange and CellMark, now plans to hold a meeting in London on 10 September to discuss its future.
The online trading portal was launched in 1997 as an exchange for woodpulp, and established itself as a leading benchmark for pulp prices.
A spokeswoman for OM London Exchange said the decision was unconnected to the OMs recent streamlining of operations.
She added that the Pulpex operation had faced questions concerning its profitability.
