Washington, US (BBN)-Donald Trump winning the US presidency is considered one of the top 10 risks facing the world, according to the Economist Intelligence Unit.
The research firm warns he could disrupt the global economy and heighten political and security risks in the US, reports BBC.
However, it does not expect Trump to defeat Hillary Clinton who it sees as “his most likely Democratic contender”.
He is rated as riskier than Britain leaving the European Union or an armed clash in the South China Sea.
China encountering a “hard landing” or sharp economic slowdown and Russia’s interventions in Ukraine and Syria preceding a new “cold war” are among the events seen as more dangerous.
“Thus far Trump has given very few details of his policies – and these tend to be prone to constant revision,” the EIU said in its global risk assessment, which looks at impact and probability.
The EIU ranking use a scale of one to 25, with Trump garnering a rating of 12, the same level of risk as “the rising threat of jihadi terrorism destabilising the global economy”.
“He has been exceptionally hostile towards free trade, including notably Nafta, and has repeatedly labelled China as a ‘currency manipulator’,” the EIU said.
It warned his strong language directed towards Mexico and China in particular “could escalate rapidly into a trade war”.
Trump has called for a “big big wall” to be built on the US-Mexican border, paid for by Mexico, to keep its illegal immigrants and drug dealers out of the United States.
On the campaign trail, Trump has advocated killing the families of terrorists and invading Syria to eradicate the so-called Islamic State group and appropriate its oil.
“His militaristic tendencies towards the Middle East and ban on all Muslim travel to the US would be a potent recruitment tool for jihadi groups, increasing their threat both within the region and beyond,” the EIU added.
Critics of Trump have raised similar concerns.
However, the businessman is moving closer to clinching the Republican presidential nominee ticket after winning most of the popular vote.
Trump, who has no prior political experience, has said his supporters would “riot” if he was denied the nomination.
In the event he does win the nomination and presidency, the EIU forecasts that domestic and foreign policymaking will be undermined.
“Innate hostility within the Republican hierarchy towards Trump, combined with the inevitable virulent Democratic opposition, will see many of his more radical policies blocked in Congress,” it said.
