    • Japan LDP leadership remains a two-horse race, Koizumi favored to win:

      • Ahead of the 4-Oct LDP presidential election, Nikkei analysis showed Agriculture Minister Koizumi favored to win, though appears to be headed for a runoff. Full-spec voting format allocates 295 votes each to Diet members (almost 90% have expressed opinions about the race) and local chapters. Koizumi was backed by roughly 70 lawmakers as of Wednesday followed by Chief Cabinet Secretary Hayashi with 50 and conservative Takaichi with 40. Article noted the Diet member count is key in the event of a runoff, where voting allocation changes to 295 Diet vs 47 rank-and-file, notably weighting the outcome towards Diet members. Still, about 70 lawmakers have not declared support for any candidate, leaving the outcome uncertain. Analysis canvassed 250 rank-and-file members derived from public opinion polls. Koizumi leading Takaichi by 33% to 28% among LDP supporters in a recent Nikkei/TV Tokyo survey. Combined tallies would give Koizumi nearly 170 votes, followed by Takaichi with ~130 and Hayashi with ~110. Election will extend to a runoff in the event nobody wins by majority in the first round -- this scenario is widely expected. Outcome will likely come down to whoever captures the most votes from supporters of Kobayashi and Motegi who were backed by nearly 30 lawmakers each.

    • Trump criticizes Beijing for stopping US soybean purchases, will raise issue with Xi:

      • Soybeans emerging as flashpoint in US-China trade talks after President Trump criticized Beijing for stopping purchases from America. Vowing to raise issue with President Xi next month, Trump echoed Republican concerns expressed on Tuesday that Beijing doesn't intend to resume purchases of US agricultural goods (Bloomberg). Press articles have highlighted how Beijing halting purchases of American soybeans as a means of leverage in US trade talks (Bloomberg). China's Commerce Minister also signaled that resumption of soybean purchases hinges on tariff relief (Reuters). Beijing has instead been preferencing soybean purchases from South American countries, seemingly inflaming US tensions with Argentina following Milei government's decision to suspend export taxes, which has led China to ramp up purchases of Argentine soybean cargoes. Trump set to meet President Milei in two weeks though White House proposal to issue credit swap line has drawn anger from Republicans, who have questioned decision to bail out Buenos Aires amid soybean situation they say is hurting American farmers (Reuters).

    • Street Takeaways: September BOJ Tankan survey

      • Economist takeaways from the September BOJ Tankan survey were generally benign in the end, after elevated attention on whether this could help clinch an October rate hike. None of the reports seen by StreetAccount indicated a shift in rate hike calls, though the October camp notably saw results as sufficient to reaffirm their stance. There was general agreement the content was mostly positive -- business confidence remains resilient, capex projections solid, labor market remains historically tight, inflation expectations remain stably elevated. Minority of negative takes on softer H2 profit outlook. Also, while price DIs eased, relative movements pointed to margin compression. Some division in views about tariff effects. Most survey responses thought to have been submitted 10-Sep, after US President Trump signed the executive order on the Japan trade agreement on 4-Sep. Optimists saw no meaningful alarm signals in business conditions outlook DIs while pessimists raised some concerns. Tariffs seemingly had limited impact on capex forecasts though may have been reflected more in the softer H2 profit outlook. In all, economists anticipating a rate hike later than October set a somewhat higher bar and looked for meaningful improvements to compel them to bring forward their calls. Conversely, October calls saw no setbacks to warrant a revision either.
