Market volatility is poised to rise again. In Japan, the obvious reason is the election of Takaichi, whose Abenomics-leanings are in conflict with the ongoing firmness of inflation. In Korea and Taiwan, the trigger is US relations. China, by comparison, looks more stable.

Japan inflation indicators are mixed, so this week's Tankan survey and Ueda speech will be important. Korea's cycle is still weak, but this week's CPI data matter less when house prices have re-accelerated. Elsewhere, China's PMI will show whether nominal growth is softening again.

Wage growth, household savings and income levels are huge issues across the region. This slidepack shows how these are linked with exchange rates to lay out the outlook for currencies in China, Japan, Korea and Taiwan.

The major themes: the ending of the first stage of China's post-2020 forced structural adjustment; in Japan, peaking of inflation but BOJ still to hike; BOK cuts but inflation higher than I would have expected; expecting renewed TWD strength. I am now away for a few days, back on September 16th.

China's structural downturn since 2021 has likely bottomed. But I think real recovery is needed for a further rally in equities. Japan's growth and inflation have survived the tariff hit, putting the BOJ back in play. For Korea, I am questioning the BOK's outlook for inflation and thus rates.

I've spent a lot of time in recent years building an infrastructure to analyse the economies of East Asia. Doing so has given me a good understanding of the data challenges in the region. In this video, I discuss those, and introduce the platform I've built to present all the data I've collected.

Data themes remain unchanged. As tariffs – perhaps – stabilise, official sentiment is catching up to the data in Japan, with growing concern about inflation. In China and Korea, market sentiment has improved ahead of the data. Given Trump's desire for a deal, that's probably more justified in China.

A comprehensive slide pack putting cyclical developments in the context of the structural themes I've been working on: 1) China, CNY v consumption; 2) Japan, Still looking different this time; 3) Korea, Becoming East Asian and 4) Taiwan, 1980s redux.

A summary of what happened on East Asia Econ last week, and what to look for in the next seven days.
