I'm not sure if the PBOC targeting 2% is scientific, or if they just thought if the Feds and other central banks does it, might as well. As I recall the origin of this mythical 2% rate in central banks around the world was kind of arbitrary.
Macroeconomics, especially dealing with large economies like China and US is often very counter intuitive and puzzling. I'm sure people here and in China have different views on consumption and what is the optimal level. PBOC is also just one branch of the Chinese government, it doesn't see eye to eye with the Ministry of Finance all the time either.
It's not science but it comes down to 0-1% is too low and 4-5% is too high, therefore 2-3 is ideal.
Personally I think what Pan Gongsheng and Yi Gang said in their position as the leader of the PBOC is correct, they are giving suggestions which from their perspective as central bankers would boost China's overall economy.
No they actually would not be allowed to talk 'deflation' unless there was significant buy-in from the Vice Premier/Politburo. Remember, PBoC is not independent like the Fed.
But this might not be the most optimal path for China though, in an extreme example, suppose China follows the path of the US and fully liberalizes the economy, the GDP would skyrocket but the end result might not be what CPC truly desires. If China one day has the highest nominal GDP, and the Yuan becomes the de facto sole reserve currency, then ironically people would be asking but at what cost?
You're not going to find me disagreeing with the risks of overfinancialization. The most important thing is the degree to which things are financialized. You should have some faith in the policymakers that the balance will be approximately right in the end, and that the direction at this moment (boost long term stable growth of stock markets and stability in real estate market) is optimal.
Remember what Xi said: 先富促共富. I wouldn't worry about US style problems unless common prosperity is taken out of the Party's goals and we have a Chinese Gorbachev sell off all SOE assets. You will also see me raise alarms if I see risks of overfinancialization (as I've posted very frequently in the AMERICAN economics thread) in China when I see that happening.
When the facts change, my opinions change.
Anyways like I said, most ppl agree with most of what you said. Is it really necessary to dunk on members here for disagreeing with 10% of what you said? Especially in a manner which can easily irritate people?
If it was true I wouldn't have a problem, but that is certainly not my perception and feel a few months back.
