Two things. First, my latest video, discussing what's not surprising about the trade surplus (the rise in capital goods), and what is (that for exports China's global market share gains have accelerated, while for imports, they've fallen). Second, an interactive dashboard on China's auto exports.

The weakness was true even for pricing, which is the focus of the most recent policy push: input prices did improve MoM, but not to over 50, and output prices fell further. That Beijing has turned its attention to oversupply should help equities, but I am doubtful that alone produces macro recovery.

Does anti-involution produce macro turnaround when the September combination of stock market and local government bail-out failed? The markets are hopeful. I am more cautious, given China's macro problems are weak demand as well as strong supply. I'd be wrong if household savings behaviour shifts.

The government is increasingly focused on the supply-side issue of corporate involution as the driver of unwanted deflation and weak corporate earnings. However, the decline in profits has been led by heavy industry, showing the importance of the weakness of property and aggregate demand.

Markets have perked up on hopes that officials will tackle over-supply. But belated publication yesterday at 8pm (!) of the PBC's quarterly opinion surveys is a reminder that business involution isn't the only challenge. Household price, income and employment expectations all continue to fall.

Based on official data, tariffs have as yet to cause any real reversal in the surge of export volumes that's now been underway for two years. That's even though export prices have, for the first time since 2003, started to rise YoY. It isn't obvious that China is absorbing the cost of the tariffs.
