News about the steel

The biggest uncertainty in the market may come from foreign steel and bulk markets. At present, the view of the domestic market generally believes that there is still room for global bulk commodities to rise. Considering that the space for economic repair and the quantitative easing policy has not been fully reflected in the real economy, it is believed that the time node for “shorting” bulk commodities has not come.

However, we believe that the peak of domestic commodity export since the epidemic may have passed, and the phenomenon of domestic steel soaring since last October driven by foreign economic repair demand may not be repeated, which needs to be treated with caution.
