China’s semiconductor output posts biggest ever monthly decline in October amid weak demand, fresh US tech export controls
SCMP article:
There is a drop in IC output, but sanctions are not the reason IMO. There is also a similar drop in IC imports, so it is mainly due to weak market. The sanctions impacted indirectly because some customer, possibly some US one, cut orders with SMIC.
If SMIC and the other China players regain some free capacity for the immediate future is not necessarily a bad thing. They are refocusing on serving local market and relying less on foreign customers.
Available foundry capacity in China is critical for the health of the whole ecosystem, foundries quarterly bottom lines are less critical (and anyhow they remain all deeply positive).
