Commenting on today's figures, Davy's David McNamara said that with global growth buoyant, 2018 looks set to be another positive year for Irish trade levels.
But the medium-term threat of a hard Brexit remains a cloud on the horizon, he cautioned.
Merrion economist Alan McQuaid also cautioned about the possible impact of Brexit on trade performance but said, at present, Irish exporters have strong momentum. "The trade outlook going forward remains clouded in uncertainty due to Brexit but we are still anticipating another solid performance this year. Indeed, we are at this juncture projecting another record surplus, of €47bn," he said.
