The press has been full of stories about the player agreeing a deal with the club, but Ferguson is adamant there is no truth in the rumours.
Sneijder has stated he is happy with the Serie A side and Inter insist that the Holland international is not for sale.
But with United understood to be in the market for a new playmaker to replace Paul Scholes, the former Ajax and Real Madrid man continues to be linked with the Premier League champions.
"I keep reading about this, there's absolutely nothing at all to that," Ferguson told ESPN.
"First of all I don't think Inter are prepared to sell him anyway.
"You get conjecture and you get speculation every week in newspapers unfortunately.
"And we have to answer these for some reason - why, I don't know, but we have to find a reason without adding insult to any particular club, or embarrassing any particular player. There's nothing we can do about it."
