Stramaccioni was promoted from youth team coach to head coach midway through last season following the sacking of Claudio Ranieri.
The 36-year-old manager helped the club steady the ship and he was confimed as head coach for the 2012-13 season in the summer - this will be his first full season in charge of Inter.
"I wasn't especially brave in choosing him [Stramaccioni], I thought he had all the attributes necessary to do the job and I was right about his qualities as a human being," Moratti told the club's website.
"I like being able to put my trust in young people and those who have made history at the club. I feel able to do so and that's the best thing."
He added: "This is a very important year, where we're building on Inter's core values - which I believe very much in."
"It's a key year, we want to be back challenging for trophies, the road will be tough and that's why I wanted to be here to thank the partners. They give us a lot of confidence and it's thanks to this that we can create a wider group which extends beyong the field of play."
The Nerazzurri opened the Serie A season with an encouraging victory at Pescara but slumped to a 3-1 home defeat by Roma in their second game.
Inter are looking to claim the Scudetto for the first time since 2010 this season.
