The Portuguese economy might be on an unstable footing with only one credit rating agency giving it with an investment grade, but such instability should lessen in the medium-term, the country's economy minister told CNBC.
The investment grade given by the Canadian firm DBRS is vital for Portugal. It allows the European Central Bank to keep purchasing Portuguese government bonds and, thus gives Lisbon lower borrowing costs.
Manuel Caldeira Cabral, the Portuguese economy minister, told CNBC that "Portugal has a lot of work to do" to convince the other credit rating firms but he is certain that, in the medium-term, the country will be getting an upgrade.
"We still have a lot of work to do, but I think our fundamentals now make us deserve a better rating than we have," Cabral said.
"I think the prospects in the medium run are for ratings of most agencies to come up. We don't expect this to happen the next day or the coming semester (six months). I think they're going to stay stable and then in the medium-term they're going to increase," the economy minister added.
The Portuguese government is projecting a deficit of 1.6 percent compared to 2.4 percent in 2016. In 2015, its public debt stood at 129 percent of gross domestic product (GDP), but, according to government data, that number should decrease slightly to 128.3 percent of GDP in 2017.
Portugal was severely hit by the 2008 financial crisis and the high level of public and corporate debt, along with a high level of non-performing loans, continue to be a drag to more growth.
"The third quarter is going to show a very interesting growth rate," Cabral told CNBC, as the economy benefits from an expansion in the tourism and technologic sectors.
