The OECD expects that the global economy will increase by 3.9% in 2018 and by 3.9% in 2019. In terms of major economies, the OECD expects China's economy to increase by 6.7% in 2018 and by 6.4% in 2019; in the euro zone, the economy will increase by 2.3% in 2018 and by 2.1% in 2019; the US economy is expected to grow by 2.9% in 2018. In 2019, the figure is expected to grow by 2.8%; the Japanese economy is expected to grow by 1.5% in 2018 and by 1.1% in 2019. It is worth noting that the OECD stated that the US tax reform will help increase the growth rate of the US economy by 0.5-0.75 percentage points in 2018 and 2019.
