The Scottish winger has attracted interest from top clubs in the Premier League, including Arsenal.
Most would not expect Bournemouth to be able to hold onto a player if a top club comes knocking. But Howe would not be drawn on the matter.
"I love Ryan to bits, so no doubt on that side [whether he wants Fraser to stay] but now is not the time to talk about any transfer speculation. Now is the time to concentrate on football," he said to reporters.
"I am focusing on football and have not had discussions with anybody about the transfer window this summer and it's not the time to do that.
"I'm just coaching the team and preparing for Brighton."
