The outbreak of coronavirus will have a larger negative effect on the global economy than the SARS (Severe Acute Respiratory Syndrome) outbreak in 2003, as any slowdown in Chinese economy would send not ripples but waves across the globe, IHS Markit said on Friday.
The virus has brought large parts of the world's second largest economy to a standstill and its impact was felt across industries.
"Coronavirus will have a larger negative effect on the global economy than the SARS outbreak in 2003. At the time of SARS, China was the sixth largest economy, accounting for only 4.2% of world GDP. China is now the world's second largest economy, accounting for 16.3% of world GDP. Therefore, any slowdown in the Chinese economy sends not ripples but waves across the globe," IHS said in a commentary on coronavirus outbreak.
If the current and unprecedented confinement measures in China stay in place until the end of February, and are lifted progressively beginning in March, the resulting economic impact will be concentrated in the first half of 2020, with a reduction of global real GDP of 0.8% in Q1 and 0.5% in Q2, it said.
In this scenario, the coronavirus and resulting measures will reduce global real GDP by 0.4% in 2020.
On the other hand, if confinement measures begin to lift on February 10, the impact on global GDP will be more limited, resulting in a 0.1% reduction in global GDP growth in 2020 and 0.4% reduction in China's annual growth.
"The effects of coronavirus are most pronounced in household consumption and somewhat mitigated in the industrial sector because factories are seasonally idle during this period. Nevertheless, in many ways China's economy is more vulnerable today than it was in 2003, with productivity and overall economic growth already slowing and the effects of the US-China trade conflict," it said.
China's GDP has risen dramatically since SARS and its impact on the world economy is much larger now.
"The slowdown in Chinese growth may be a significant drag on global growth. In 2002, China contributed 23% of world GDP growth, in 2019 China contributed an estimated 38% of world growth," IHS said.
