The Blues have an option to recall defender Ake,who has starred on the south coast after netting three times in six Premier League starts, next month.
Howe, whose side face Swansea today, said: “You sort of hope the phone doesn’t ring, or you could just ignore the phone when it does.
“We have had no conversation with them at this moment in time.
“It is there decision and their right if they need Nathan back to make that call. We are hoping he stays with us.
“Nathan Ake looks happy and he has been producing”
“Nathan looks happy and he has been producing. That has not been a major concern of mine.
“I would like to think Chelsea are happy where he is and how we have treated the player and the development we are putting in to him.
“That was the purpose of the loan. It improves his football knowledge and experience and hopefully they achieve their goal.”
Howe is the second longest serving boss in the top flight, but after Bob Bradley’s Swansea exit admits he is worried about the future of his profession.
He added: “It is worrying for the future of management when I’m one of the longest serving. Managers aren’t being given the time.
“There is such a short term reaction to a win or defeat and those extremes in emotion cannot be healthy for the future of management.
“I don’t feel under any pressure immediately. But I share the emotions of any manager when you lose and you lose a run of games.
“You feel a feeling of failure, you feel you are not being a success in your.”
