Phison CEO: "2027 capacity constraints will be even more severe than in 2026." "Upstream suppliers need up to 4 years from plant construction and equipment investment to actual production.

The consolidation underscores Beijing’s escalating effort to contain risks in the country’s fragile regional banking system through mergers and acquisitions, creating larger and better-capitalized institutions to help withstand economic pressure. Even so, asset quality remains a key challenge. A recent report from the Shanghai Institution for Finance and Development said regional banks continue to face pressure from local government financing vehicles, retail lending and the property sector, particularly in lower-tier cities."↗ @michaelxpettis · 请求账号 @michaelxpettis · 2026-08-17 03:42:23 UTC · 引用原帖：As Setser notes, a revaluation of the RMB is a necessary part of any reasonable global rebalancing. It is not the only policy, nor even necessarily the best policy, but it is the only realistic policy that can be implemented quickly enough to matter to China's trade partners, even if -- for that very reason -- this also makes it hard for Beijing, who would prefer a much slower rebalancing.↗ @aleabitoreddit · 请求账号 @aleabitoreddit · 2026-08-17 02:52:12 UTC · 原创原帖：I think we're seeing AI server MLCC demand cause an interesting effect... with tightening capacity for consumer/general-purpose MLCCs. If you get Vietnam flashbacks like I do to $MU / Samsung / SK Hynix -> Legacy DRAM: My thesis is we'll see the same thing here maybe late H2, early 2027 with consumer/broad MLCCs. From July 6th: "the crowding-out effect from AI-oriented high-end MLCC production has begun spilling over into both the automotive and consumer markets." July 28th: "AI Demand Pushes Japanese and Korean MLCC Suppliers to Record Monthly Shipments; Consumer-Grade Order Spillovers Continue to Surge" Aug 12: As [MLCC] capacity shifts from consumer grades to AI-oriented products... (Trendforce) Aug 12: China's electronics market channel checks found 22µF and 47µF MLCCs (used more broadly) out of stock. Then found and said certain manufacturers had stopped taking orders. (for reference: Walsin said high-volume smartphone/PC products such as... 22µF, so it's broader MLCCs) Obviously Samsung Electro-Mechanics/Murata are main beneficiaries of AI server MLCC ramp. But companies with large market share of overall MLCCs like Taiyo Yuden (6976, disclosure: I have positions) with less AI server share, would be a major beneficiary of this. Fun part is, we're only in H2 2026, so the next major bottleneck should be fun!↗ @aleabitoreddit · 请求账号 @aleabitoreddit · 2026-08-17 01:39:22 UTC · 原创原帖："Severe InP Shortage Triggers Largest Price Hike Ever" - $AXTI. Suppliers have bluntly stated that "even if you have the money, you still may not be able to get the material" (lol). - Industry sources revealed that InP substrate prices began rising in Q4 last year and was the fourth consecutive substrate price hike. - The latest Q4 hike is expected to be >10%, - Meanwhile, prices for epitaxial wafers made from those substrates have already been raised two times, and the market is moving toward a 3rd consecutive increase in Q4. (I also wrote a thesis on $IQE, which benefits here too). Article states VPEC, Landmark, IET benefits (Taiwan centric reporting). I did predict this last year... The bottleneck is real, but I do have higher expectations for price hikes that comes next. Glad it's starting to play out.↗ @thsottiaux · 请求账号 @thsottiaux · 2026-08-17 00:36:11 UTC · 原创原帖：Codex ✅ Almost 100% reliable ✅ Occasional resets ✅ Open-source ✅ (will have Astra)↗ @aleabitoreddit · 请求账号 @aleabitoreddit · 2026-08-17 00:34:43 UTC · 原创原帖：Stripe reportedly buys OpenRouter for $7 Billion. I think their orchestration is easy to replicate and switch from. And there's very little moat. But atm, OpenRouter has the userbase, valuable dataset, + momentum. What's your take... Yay or Nay for the payments firm?↗ @thsottiaux · 请求账号 @thsottiaux · 2026-08-17 00:13:16 UTC · 引用原帖：GPT-5.6 Sol 1M in Codex. This used to only work for API keys, but we just flipped the switch and works for usage through ChatGPT accounts now too. The same warning applies, there is a reason the current context length is the default, we have tuned it to ~perfection.

We don't think the world can afford to continue to be patient and absorb the impact of China's highly unbalanced growth model↗ @thsottiaux · 请求账号 @thsottiaux · 2026-08-16 20:12:29 UTC · 原创原帖：Here is how to enable a 1M-token context window in Codex for GPT-5.6 Sol. Even though we have tuned the context limit in Codex to be set optimally when it comes to performance and cost, this is a common ask, so here it is documented. A larger context window lets Codex retain more code, tool output, and conversation history before summarizing older material. You need a model that supports it. And GPT-5.6 Sol, for example, has a documented 1,050,000-token window. Open ~/.codex/config.toml and add or update these settings at the top level, before any [section] headers: ``` model = "gpt-5.6-sol" model_context_window = 1000000 model_auto_compact_token_limit = 900000 ``` The first setting selects the model. The second tells Codex to use a one-million-token context budget. The third starts automatic history compaction around 900,000 tokens, leaving some headroom. Restart Codex client and start a new session after saving. To try the configuration for a single CLI session without changing your defaults: ``` codex -m gpt-5.6-sol \ -c model_context_window=1000000 \ -c model_auto_compact_token_limit=900000 ``` Have fun, but also know that we tuned the default carefully!↗ @Brad_Setser · 请求账号 @Brad_Setser · 2026-08-16 20:09:56 UTC · 引用原帖：To be clear, I am not calling on China to remove its capital controls, nor is Xi likely to suddenly liberalize the financial account The IMF's estimate of undervaluation are based on the "current account" model, and right now current account based flows are generating real appreciation pressure.↗ @thsottiaux · 请求账号 @thsottiaux · 2026-08-16 20:03:51 UTC · 原创原帖：Sunday is for good vibes. As is any day of the week, but especially Sunday.↗ @Brad_Setser · 请求账号 @Brad_Setser · 2026-08-16 18:36:04 UTC · 原创原帖：Dunno, seems like China's currency might be a wee bit undervalued -- Massive export performance v global trade, large growth contribution from global exports, around its 2008 level v the dollar and its 2012 level of the BIS index ...↗ @aleabitoreddit · 请求账号 @aleabitoreddit · 2026-08-16 18:33:00 UTC · 引用原帖：I think @elonmusk said it best: “Robots don’t all need to be humanoid. But a general-purpose robot intended to replace human labor should fit the world humans already built. Roger, roger.” Personally, I expect $TSLA Optimus form factor to converge to the right image.↗ @Brad_Setser · 请求账号 @Brad_Setser · 2026-08-16 18:29:41 UTC · 引用原帖：Worth a read :)↗ @Brad_Setser · 请求账号 @Brad_Setser · 2026-08-16 17:54:05 UTC · 原创原帖：Appreciation of the renminbi is central to any realistic plan for reducing the global spillovers from China's ever-growing surplus.
