Central bank Governor Patrick Njoroge has repeatedly denied undue interference in the market, saying the regulator was merely playing its role of enforcing discipline.
"We, through the central bank of Kenya, are having conversations to reinstate the interbank foreign exchange market," Ruto told an event at the securities exchange.
The lack of a vibrant interbank foreign exchange market has partly been blamed for a biting shortage of hard currency that has even forced the government to seek
longer credit periods for essential imports like petrol.
It has also given rise to a parallel market, with
money-changers quoting a different foreign exchange rate to the
official central bank one, with a divergence of about 10%.
