The Netherlands international goalkeeper extended his contract with the Swans last month and committed himself to the Welsh club until June 2016.
"We are hoping that Michel signing will encourage others to do the same," Graham told GK Icon.
"The chairman (Huw Jenkins) has acted quickly in giving Michel a new deal. Ashley Williams, Neil Taylor and several others are also being sorted out. Michel stated he wanted to stay because he can see something special happening.
"For Michel to say that when he has been linked with some top teams is a great thing and hopefully the chairman can use that to his advantage and tie down some more players on contracts, and bring other players in to help the squad move forward."
Graham joined Swansea from Watford in 2011.
