Singapore has reported dismal preliminary second quarter growth data, including the slowest pace of annual expansion in a decade.

The data raised bets that a recession and monetary policy easing could be coming. 

The quarter's 0.1% gross domestic product (GDP) expansion was below the 1.1% forecast in a Reuters poll and the slowest annual growth since 2009's second quarter, when it fell 1.2%. 

Singapore's trade ministry also said the economy shrank 3.4% on a seasonally adjusted and annualised basis.

This was- the biggest contraction in nearly seven years compared with a poll forecast of 0.1% growth and January-March's 3.8% expansion. 

The slump in Singapore - often seen as a bellwether for health of the global economy - is the latest evidence that momentum has slowed across Asia as the year-long US-China trade war and sliding growth weigh on the region's export-reliant economies. 

Elsewhere in Asia, analysts say South Korea may also be flirting with recession, while China on Monday is expected to report its slowest economic growth in at least 27 years. 

Analysts said the main drag for Singapore remains the manufacturing sector. 

In the second quarter, manufacturing contracted 3.8% from a year earlier after shrinking 0.4% in the quarter earlier. 

Singapore authorities have previously said they will review their 2019 full-year GDP growth of 1.5%-2.5%, and some analysts say there might be a recession in 2020. 

The standard technical definition of a recession is two consecutive quarters of economic contraction. 

Electronics manufacturing output, the main driver of Singapore's economy in the last two years, declined for the sixth consecutive month in May while exports saw its biggest decline in more than three years. 

Analysts described Singapore's economy as at a "stand-still" in the second quarter and said that with global trade still reeling from trade tensions and broader global slowdown, downside growth risks remain.

In a Reuters poll done after release of the second quarter data, seven of 11 economists said they expect the Monetary Authority of Singapore to loosen its exchange-rate monetary policy in its next policy statement, due in October, with the other four forecasting no change. 

The MAS tightened monetary policy twice last year in efforts to control rising price pressures and strengthen its currency - its first such tightening moves in six years.
