When the US kicked off 2018 by imposing tariffs on solar panels and washing machines, it was not expected the trade disputes would escalate into a full-fledged war. However, such optimistic sentiments in the market have dissipated since mid-June.

The escalation of the trade war has caused an abrupt fall across various stock markets, especially in China. Shanghai Composite fell nearly 8% after China retaliated to the US tariffs on $50 billion worth of Chinese products, which the Trump administration later escalated to be a $200 billion list. Emerging market currencies are also under huge depreciation pressure from capital outflows.

To help evaluate whether the market response is warranted or exaggerated, we measured the trade impact of additional import tariffs based on standard economic theory, namely two key parameters—the tariff pass-through rate and the price elasticity of demand.

On that basis, we estimate that, with the 25% of import tariffs, the expected increase in import tariffs could hover around 5%, while the reduction in import volume could reach 20%. This is equivalent to a net reduction of about 15% in import value, or a maximum loss of $5 billion (15% of $34 billion). Furthermore, the direct impact could even be smaller due to trade rerouting and substitution by third countries.

The new normal: Reactive markets

While the direct impact seems small, one should not forget that financial markets react to expectations of an additional escalation of a trade war, let alone a full-fledged technology arm race, which would bring even more uncertainties to the world. Hence, it is time to embrace the “new normal,” where markets react to negative expectations of limited immediate impacts of a trade war.

The end of multilateralism seems clear, at least for trade. However, one should also bear in mind that the world is no longer flat. Beyond trade, the US is also building up barriers to flows of investment, knowledge and talents. For example, the US has ratcheted up its efforts to vet China’s investments, especially those into US high-technology companies. The most obvious instrument has been the Committee on Foreign Investment in the United States, a large part of whose actions have targeted China and especially the manufacturing and industrial sectors. In addition to investment, the US could restrict the flow of talent and knowledge via tightening student/working visa issuance to Chinese citizens.

Implications for Europe

As the US raises the stakes at the negotiation table, it is hard to imagine how China can accommodate the demands from the US. It seems that China does not have many effective ways to retaliate without hurting its long-term development. The best strategy it can take is to continue to open itself to the rest of the world. Because the EU is the largest economy outside the US, we should expect China to be much more willing to collaborate with Europe in the future and accept some of the EU’s longstanding requests on China to move further in their economic cooperation, namely better market access and reciprocity.

Within this context, the impact of what we considered to be a paradigm shift in terms of US-China economic relations could potentially benefit the European Union, which heavily depends on a number of general and sectoral factors. For the general consideration, the key is the response of the EU Commission (i.e., whether it will align with the US to protect its market from Chinese exports, or will maintain neutral policies). In the latter case, Europe could substitute the US and China in each other’s markets to some extent. At a more granular level, the situation is clearly very different across sectors.

At the first glance, the US and EU’s exports to China are very similar. China’s top five imports from the US are chemicals, transport equipment, motor vehicles and medical instruments. China’s top five imports from Europe are motor vehicles, machinery and equipment, chemicals, medical instruments and transport equipment. If the EU does not take sides and the US does not hit the EU directly, European industries’ potential market is quite relevant for motor vehicles and aircraft sectors—and more to come from the list of tariffs on the $200 billion worth of products.

If we assume that the EU could take up all the market shares of the US and China in the counterparties’ market, potential gains for European exporters are huge. Based on the lists released by both parties in April, we find that European auto manufacturers have the most to gain in both the US and China markets. Chemical products and machinery are the sectors that could potentially benefit from the tariff measures by the US. As for the gains in China’s market, European aircraft manufacturers are more likely to realise the gains as they do not face major competition from the other countries. Although China removed aircraft from the list of products subject to tariffs released in July, European aircraft manufacturers are better positioned to enjoy the benefits if China decides to escalate.

For the US tariffs on an additional $200 billion worth of Chinese imports released on July 10, European manufacturers of consumer goods are expected to grasp the opportunity and expand their market share in the US market. Noticeably, European exporters have the capacity to expand their market share as they already take up great shares in the global market for many products. The EU now supplies more than 40% of global imports for furniture, metal, plastic and paper products.

Which sectors benefit?

To more accurately quantify the benefits at a sectoral level, we constructed a Trade Complementarity Index. The sector benefiting the most is the semiconductor industry, which could potentially expand its exports more than three times its current exporting value. However, when the relative size in the EU’s export structure is taken into account, the most relevant gains occur in motor vehicles, aircraft/spacecraft and chemical products, with the maximum potential gains reaching 24%, 66% and 17% of their current exports. The benefits for the other sectors vary with their sizes and potential gains. For example, the semiconductor sector can potentially expand by as much as 3.57 times its current exporting value, whereas iron and steel only see a marginal benefit of 21% of its current exports at maximum.

Another important finding of our analysis is that the potential export gains are larger in the US market. In other words, within the sectors that the EU already exports, the substitution of China’s exports to the US accounts for 68% of total potential gains (equivalent to $69 billion). The China market, instead, offers a potential gain of up to $32 billion to the European exporters (as far as the substitution of US products is concerned). The takeaway of this is that European exporters benefit more from US sanctions on China than from China’s retaliation. Of course, such sectoral gains can be wiped out if US imposes import tariffs on Europe.

We should note, however, that no due care has been taken with the complexities of the value chain in this analysis, which makes our results less obvious for goods of which components are produced in the US and/or China (rather than being vertically integrated within the European production chain). Also, if China were to accept the US demand and expand its imports from the US, European sectors heavily dependent on exporting to the Chinese market would be severely affected.

In sum, our analysis suggests that Europe should benefit from the US-China trade war. This is especially the case for those sectors that can substitute the US or Chinese exports into China and the US, respectively. As long as Europe does not meddle in the US-China frictions, the most obvious winning sectors would be motor vehicles, aircraft, and chemical products.
