- Lucas: So Taiwan's stock market ETF — ticker E-W-T — is up more than four and a half percent over the past five days. That puts it among the best-performing emerging-market index funds in the world right now. Luna: And this is happening while a lot of other emerging markets are selling off. India's down. Brazil's down. Taiwan is the outlier. Lucas: Right. And the obvious narrative is chips. Taiwan Semiconductor Manufacturing Company — TSMC — is the largest company in the index. But I think the trade data tells a more interesting story than just one stock going up. Luna: Before we go deep — quick honest thing. A handful of listeners chip in monthly through buy me a coffee dot com slash fexingo, and that's literally what funds making this many episodes possible. No ads, no sponsors. Just listeners who find value in the show. So if these conversations have moved your work forward in some small way, that's where you can keep it going. Lucas: Yeah, genuinely. It's a small group, but it's what keeps the whole operation ad-free and independent. Luna: Okay, back to Taiwan. So what's the trade data saying that the stock price alone isn't? Lucas: Well, Taiwan's total semiconductor exports have grown at a compound annual growth rate of roughly twelve percent over the past five years. But here's the thing — the share of those exports going to just three markets — China, the United States, and Hong Kong — has actually increased over that same period. It's not diversifying. It's concentrating. Luna: Concentration risk. If something disrupts the Strait, half the world's advanced chips stop moving. Lucas: Exactly. And that concentration is visible in the trade balance data too. The US goods and services trade deficit widened to about sixty billion dollars in March, and a significant chunk of that is semiconductor imports from Taiwan. The dollar is still strong — trade-weighted index around 119 — which makes imports cheaper, but it also masks the dependency. Luna: So the strong dollar is kind of papering over how reliant we've become on one island for critical inputs. Lucas: Right. And that's the tension. The EWT rally reflects genuine earnings momentum — TSMC's advanced packaging capacity is sold out through next year. But it also reflects a market that's pricing in zero geopolitical disruption. And the historical data suggests that's a fragile assumption. Luna: Let's talk about that advanced packaging piece, because I think a lot of people hear 'semiconductor' and think only about the lithography — the extreme ultraviolet machines. But the bottleneck right now is actually packaging. Lucas: Huge bottleneck. TSMC's CoWoS packaging — that's chip-on-wafer-on-substrate — is the key technology for NVIDIA's AI accelerators and AMD's MI series. And TSMC is building new packaging facilities in Taiwan, Japan, and Arizona. But building a packaging plant takes two to three years. In the meantime, the existing capacity is running at full tilt. Luna: And that capacity is almost entirely in Taiwan. So the supply chain for AI chips — which everyone agrees is a strategic asset — goes through one island's advanced packaging fabs. Lucas: That's the heart of the trade story. And it's not just AI chips. Automotive semiconductors, industrial microcontrollers, even the chips in your phone — a huge portion of them go through Taiwan for some stage of manufacturing or packaging. Luna: So when you see EWT up four and a half percent, it's not just a tech rally. It's a bet that nothing changes in the cross-border flow of these components. Lucas: Precisely. And the counterargument is that reshoring efforts are real. The US CHIPS Act has allocated over fifty billion dollars in subsidies. TSMC is building three fabs in Arizona. Samsung is expanding in Texas. Intel is building in Ohio. But here's the catch — even those new fabs will initially rely on Taiwanese subcontractors for equipment installation, materials, and process know-how. Luna: So the supply chain is still anchored in Taiwan, even as the final assembly moves elsewhere. Lucas: Right. And that's why the trade data matters. If you look at the import numbers for semiconductor manufacturing equipment, Taiwan is still the largest buyer globally. They're not just making chips — they're building the factories that make the machines that make the chips. It's a deep ecosystem. Luna: Which brings us back to the ETF. EWT is heavily weighted toward TSMC, but it also holds a lot of the equipment and materials companies. So the rally is broad-based. Lucas: Exactly. The top ten holdings include TSMC at about thirty percent, but then you've got MediaTek, Hon Hai Precision — that's Foxconn — and a bunch of smaller specialized firms like ASE Technology and Win Semiconductors. All of them benefit from the same structural demand. And all of them face the same concentration risk. Luna: So what would break the rally? I mean, the geopolitical headlines have been alarming for years, but the market keeps going up. Lucas: The market is pricing in a low probability of actual disruption. But if you look at the options market, the cost of hedging Taiwan exposure has increased. The implied volatility for EWT options is higher than for the broader emerging-market ETF. So there is some fear priced in, just not enough to derail the momentum. Luna: And the yen at 159 to the dollar — that's also a factor, right? Because a weaker yen makes Japanese semiconductor equipment cheaper, and some of that equipment flows into Taiwan. Lucas: Absolutely. Japan is a major supplier of the chemicals and precision tools used in Taiwanese fabs. So the yen depreciation actually lowers input costs for Taiwan's chipmakers. That's a tailwind that gets overlooked. Luna: And the yuan? It's been relatively stable against the dollar, around 6.77. That matters because China is still a big end-market for Taiwanese chips. Lucas: Right. A stable yuan means Chinese buyers aren't facing a sudden cost increase for imported chips. That supports demand. So you've got multiple currency dynamics all aligning in Taiwan's favor. That doesn't happen often. Luna: Let's zoom out for a second. What does this mean for a multinational that's trying to build a resilient supply chain? Lucas: It means you need a dual strategy. One, you optimize for the current reality — which is that Taiwan is irreplaceable for the next three to five years, at least. So you lock in supply agreements, you invest in joint capacity, you maybe even prepay for future output. Two, you simultaneously build redundancy — alternative packaging lines in Japan or the US, even if they're more expensive. Luna: Because the trade data suggests the concentration isn't going away on its own. Lucas: It's not. In fact, the us china trade tensions have actually reinforced Taiwan's position. Chinese companies, worried about being cut off, have been stockpiling Taiwanese chips. That shows up in the export data. So the very thing that was supposed to diversify the supply chain — tariffs, decoupling — has, in the short term, made it more dependent on Taiwan. Luna: Interesting. So the EWT rally is partly a function of geopolitics, not despite it. Lucas: Exactly. And that's the paradox. The market is betting that the status quo holds, even as policymakers try to change it. For now, the trade numbers support that bet. But the risk is that one event — a blockade, a sanctions escalation, a natural disaster — could invert that logic overnight. Luna: So the question becomes: how do you price a tail risk that's never been realized in modern markets? Lucas: That's the billion-dollar question. And I don't have a clean answer. But I do think the trade data is a better guide than the stock price. The stock price reflects sentiment. The trade data reflects real physical flows of goods. And those flows are saying: this island is the world's chip factory, and there is no backup. Luna: Yet. Maybe in five years we'll look back and see that 2026 was the peak of concentration. Lucas: Maybe. But for now, the data says Taiwan's semiconductor exports are still accelerating. And until that trend breaks, the trade story — and the market story — is going to be written in Hsinchu, not in Phoenix nor Dresden.
