For an island measuring a little less than 14,000 square miles (or about the size of Belgium), Taiwan plays a crucial role in global supply chains, making geopolitical concerns associated with it of keen interest to most major corporations.
Taiwan has essentially acted as an independent nation since 1949, when the nationalist government under Chiang Kai-shek retreated to the island following the communist takeover of mainland China. Yet China has made no secret of the fact that it wants to bring Taiwan back under its authority—ambitions that were brought to the fore in October when China launched military drills that simulated an attack on the island.
If China were to invade Taiwan, it could have serious political and social consequences that would ripple around the globe. And it would be particularly devastating to our supply chains, says consultant Ashray Lavsi, a principal at the global procurement and supply chain consultancy Efficio. He specializes in solving complex supply chain, operations, and procurement problems, with a special focus on resilience. Prior to joining Efficio’s London office in 2017, he worked at XPO Logistics in the U.S. and the Netherlands.
Lavsi spoke recently with David Maloney, Supply Chain Xchange’s group editorial director, about what might happen if China moves to annex Taiwan—what shortages would likely arise, the impact on shipping lanes and ocean freight costs, and what managers should be doing now to prepare for potential disruptions ahead.
It’s no secret that China has ambitions on Taiwan. If China were to attempt to seize control of Taiwan, how would that affect the world’s supply chains?
There would be wide-ranging disruptions around the world. The United States does a lot of trade with both China and Taiwan. For example, the U.S. imports about $470 billion worth of goods from China, while China imports about $124 billion from the U.S. Meanwhile, Taiwan is the No. 9 trading partner for the U.S. So all of this trade could come to a halt, depending on the level of conflict. Supplies would likely be disrupted, and trade routes could be affected, resulting in delays and higher shipping costs.
Furthermore, there would likely be disruptions to trade not just between the U.S. and China, but also across the board. It could very well be that the NATO members get involved, that South Korea gets involved, that Japan gets involved, the Philippines get involved, so it could very quickly spiral into widespread disruptions.
We’ve seen big changes in the way businesses in Hong Kong operate since Britain handed control of Hong Kong over to China nearly 30 years ago. If China were to succeed in bringing Taiwan under its authority, would we see a similar outcome?
Indeed, I would expect so. I read recently that since around 2020, foreign direct investment in Hong Kong has dropped by nearly 50%, from $105 million to $54 million. The drop was primarily because of increased regulatory oversight. There are now a lot of restrictions on freedom of speech as well as tighter control over business operations. Something similar could very well happen in Taiwan if China were to succeed in taking over the island.
As you mentioned, the United States conducts a lot of trade with both Taiwan and China, and both countries have become strategic supply chain partners. Beyond the diplomatic considerations, what would a military or economic conflict mean for the United States?
There is a lot of trade in goods like agricultural products, aircraft, electronic components, and machinery, and our access to all of those items could be cut off. On top of that, China controls 70% of the world’s rare earth minerals [which are crucial for the production of a wide variety of electronic devices]. So any conflict in the region would almost certainly result in many disruptions, particularly in critical sectors like technology and electronics—disruptions that would lead to shortages and increased costs.
Trade routes would also be affected, resulting in delays and higher shipping costs. U.S. companies would need to seek out alternative suppliers for critical materials or components they currently source in China, if they haven’t already. And if they haven’t lined up alternative suppliers, any hostilities could result in a complete halt in production.
What effect would such a move have on the global economy?
It’s been quite a few years since economies have just been localized. Any disruption now has widespread ripple effects across the world. As we discussed, any conflict between the United States and China naturally pulls in countries like Japan, South Korea, the Philippines, and the NATO countries, and it can very quickly spiral out.
Look at the semiconductor, or chip, shortages. If you recall, back in 2021, those shortages led to almost a half-trillion-dollar loss for the automakers, who lost out on sales of 7.7 million vehicles because they couldn’t meet demand. We could see a repeat of that situation—maybe even on a larger scale.
I found this statistic interesting—we often talk about the semiconductor shortages during the pandemic, but if you look at true production numbers, the actual production of chips went up from 2020, to 2021, to 2022. The shortage was driven not by a drop in production, but rather, by a surge in demand for PCs from people working from home. That demand has since dwindled, but we’d still face a major semiconductor shortage if much of the production were halted. So that’s going to be a very big change, a very big disruption.
Of course, the United States, along with a number of other countries, has taken steps to reduce its exposure to risk by bringing some semiconductor production back to its own shores. But it will take time to get those operations up and running, and their output would still be just a drop in the bucket compared to what’s needed. So what would a takeover of Taiwan mean for the overall semiconductor flow?
It essentially stops, right? Let me paint a picture that illustrates the importance of the Taiwanese semiconductor industry to global manufacturing. Semiconductors go into everything from cars to military equipment to computers to data centers to microwaves—they are in everything around us. Taiwan produces 60% of the world’s semiconductors and more than 90% of the advanced chips. Just let that sink in: More than 90% of all the advanced chips produced worldwide come from Taiwan, primarily from a big fabrication company called TSMC.
So the complexity and the precision required to make advanced semiconductors, combined with the limited number of companies around the world, make Taiwan’s position unmatched. The second-largest producer after TSMC is South Korean-based Samsung, which produces 18%, so that’s the gap that we are talking about.
As you rightly said, there are efforts by governments across the world to reduce their reliance on Taiwan. For example, TSMC is building three fabrication facilities in Arizona—the third with funding from the U.S. government. The first plant is set to go live next year and the third by 2030. But even once all three plants are up and running, the production volumes won’t be close to what TSMC produces in Taiwan. It’s going to take years to reduce our reliance on production in Taiwan. If that supply is cut off, the ripple effect will be tremendous.
Setting aside the historical and political claims China has made on Taiwan, is Taiwan’s dominance in the semiconductor industry a main reason why China has set its sights on it?
It could be. China has been investing heavily in chip production—for instance, today, most, if not all, of the chips in the latest Huawei phones are locally produced in China. But China is still quite a few years behind TSMC. So that’s definitely going to be one of the big factors, right? One article that I found very interesting declared that chips are the new oil. If you control chip production, you control the global market.
Let’s talk about the implications for shipping lanes. If you take a look at the map, you realize that the Taiwan Strait is a very important shipping lane for containerized goods coming out of both China and Taiwan. If China were to institute a military blockade, how would that affect the world’s container flows?
That flow would be affected tremendously. The Taiwan Strait plays a crucial role in global shipping, particularly for goods moving between Asia and the rest of the world. It is one of the busiest shipping lanes, and any blockage would severely disrupt global container flows.
Now let me put that into perspective. Fifty percent of the world’s containerships pass through the Taiwan Strait—50%. That’s a huge number. By comparison, the Suez Canal handles about 20% of global trade. Or to use another measure: 88% of the world’s largest ships by tonnage passed through the Taiwan Strait in 2022.
I’ve been reading up on this in the past few months and it seems that a military blockage is a very likely scenario—one that would cripple Taiwan’s economy without a full-scale invasion. So instead of a mounting a full-on attack, China might just block the strait, which would lead to delays in the delivery of goods, affecting global supply chains and causing shortages across Asia and the U.S.
Given the escalating tensions between China and Taiwan, should shippers and manufacturers be preparing today for a potential conflict?
Businesses have to begin preparing today. If businesses were to say, “Okay, I’m going to wait until the conflict breaks out, and then figure out what I’ll do,” it will be too late. You’re done. Your production comes to halt. You can no longer satisfy your customer requirements. So proactive measures are an absolute requirement.
What should they do to prepare?
I would urge manufacturers and shippers to take what’s essentially a two-pronged approach.
First, you need to segment and identify your critical components, based on how crucial they are to your production operations and the risk associated with their sources, where they’re coming from. After you segment them, you list your top-priority items—the critical components that you absolutely cannot do without. You then split your supply chain into two, so that you have a much more redundant supply chain built for those critical items and then a second supply chain for everything else.
To build redundancy, you establish multiple suppliers and diversify them geographically. You also build in stringent contingency measures, which could include strategic stockpiling, nearshoring, and friendshoring, which is where you store inventory with an ally or in a friend consortium, as well as buying alternative components wherever possible. So all of those measures need to be put in place for the components that you’ve identified as absolutely critical for your production.
What is the second prong?
The second prong is the need to manage increased costs. There’s no getting away from higher costs, right? If you’re holding more inventory, you have higher inventory carrying costs. And if you’re diversifying your supply base, that means you don’t have as much leverage [with individual suppliers]. You’re also going to be managing multiple supply chains, which requires an increase in human capital because you’ll need more people to manage the more complex supply chains that you’re putting in place.
One way to manage costs could be by implementing strategic sourcing programs across the board that are aimed at mitigating some of the expenses. By taking these steps, manufacturers can safeguard their operations against potential disruptions and ensure continuity.
A lot of U.S. companies have been nearshoring to Mexico, which has now become the United States’ leading trade partner. Is that a simple solution for companies looking to reduce their reliance on Asia?
It is one of the solutions. But you won’t be able to replace your Asian supply base immediately—as with semiconductors, it may take a few years to build out that capacity.
So you need to start stockpiling essential components now—particularly if you won’t be able to find alternatives. You want to make sure that you’re holding the right amount of inventory of the components that you absolutely need. So nearshoring is an option, but you need to be careful what you move to Mexico.
Is that because moving production to Mexico will raise your costs compared to sourcing in Asia?
Yes, production costs will be higher compared to a place like Vietnam, where wages are currently lower than in Mexico. It might reduce the logistics cost, but I think there’s still a net increase overall because you’ll have higher expenses for things like regulatory compliance. Plus you’ll have the one-time cost of setting up the facilities.
Ideally, you’ll never have to face these problems we’ve been talking about, but it’s always better to be prepared.
