This is despite the strong 2.5% GDP growth print in Q1.
Singapore is poised to end the year with a 1.9% economic growth, slightly lower than 2016's 2% expansion.
According to BMI Research, this is due to Singapore being a trade-dependent economy.
"Singapore's external outlook is heavily dependent on the global environment and we expect the global geopolitical climate to remain uncertain amid risks stemming from Brexit and a possible rise in global trade protectionism," BMI Research noted.
This will, in turn, negatively impact the city-state's various sectors, resulting in an uneven performance in the economy. External uncertainty will also weigh on the employment outlook, with wages increases likely to remain weak amid the ongoing restructuring of the labour market.
"However, the government's forward-looking 2017 budget is likely to lead to continued investment in various sectors in a bid to move up the value chain and increase productivity. This, in addition to the robust global demand for semiconductors, will cap excessive weakness," the firm explained.
In terms of production approach, growth was uneven across the three main sectors, with manufacturing outperforming in the past quarter with a 6.6% expansion.
BMI believes that the uncertain global outlook will weigh on Singapore's manufacturing sector, with the small and open economy being highly dependent on a stable environment for its economic prosperity.
