Trump's trade war may benefit most global economies

The Sino-American clash will shift global trade significantly.

The Sino-US trade war may lead to some losses for China, but those losses will likely be dwarfed by the costs incurred by the US itself. Also, a substantial share of US-China trade is likely to be diverted to Europe, Japan and other Asian economies close to China.

THE contours of US President Donald Trump's trade strategy are becoming clearer by the day. America's trading partners face dramatic threats. But, as the revamp of the United States-Korea Free Trade Agreement and the "reform" and renaming of the North American Free Trade Agreement (Nafta) demonstrate, most countries need to offer only minor concessions to appease Mr Trump. The only country Mr Trump really cares about - his "public enemy No 1" - is China.

The scene is thus set for a Sino-American showdown, with all of its weighty and unforeseeable geo-strategic implications. But, for the rest of the world, this might not be such bad news. In fact, economic theory suggests that there is truth in the old adage: "When two quarrel, the third rejoices."

Until recently, trade policy overwhelmingly served liberalisation. From the 1960s to the 1990s, this process was driven primarily by generalised reductions in tariffs, agreed under the auspices of the General Agreement on Tariffs and Trade and the Gatt's successor, the World Trade Organization. Yet the most recent attempt at universal tariff reduction - the so-called Doha Round - never came to fruition, mainly because India (not China) opposed opening up some of its key markets.

Market voices on:

To some extent, regional trade agreements - which typically included like-minded economies that were already deeply integrated - helped to sustain the liberalisation momentum. But economists have always been sceptical about such agreements, because they are by nature "preferential". When trade barriers are lowered for the few trading partners included in the regional agreement, producers in those countries tend to shift their attention to those partners, causing imports from other countries to decline.

In other words, rather than spurring increased trade overall, regional agreements may primarily divert it: trade increases among participating countries, to their benefit, but declines for third parties, which incur (small) costs. A huge amount of empirical literature on existing preferential trade agreements supports this conclusion.

This suggests that, if a group of major trading countries does the opposite - increasing tariffs only for one another - third parties should benefit. So, should other countries - from Europe to Asia - welcome the "negative preferential trade agreement" according to which the US and China are effectively operating?

With the US imposing higher tariffs on Chinese goods, European producers will enjoy a competitive advantage over Chinese producers in the US market. Likewise, in the Chinese market, both European and Asian producers will have a competitive advantage over US producers.

A substantial share of US-China trade is thus likely to be diverted to Europe, Japan and other Asian economies close to the Chinese market. The European Union is likely to reap particularly large benefits, because it remains one of the largest trading partners of both the US and China, and because European producers are often US companies' closest competitors.

While virtually any negative preferential trade agreement would probably have some benefits for third parties, those benefits are likely to be particularly large in the case of a US-China "agreement". Trade diversion has often been regarded as a theoretical construct with little real-world significance, because most of the economies engaged in preferential trade agreements already had rather low tariffs. As a result, any change to the tariff - and thus its broader effect on trade - has been small.

The Sino-American trade war is different, because the two economies, previously rather open to each other, are imposing substantial trade barriers. Already, the US is imposing a 10 per cent tariff - four times the US average - on more than US$200 billion worth of Chinese goods. Next year, that tariff may be increased to 25 per cent (ten times the US average tariff on imports from other countries) and expanded to include a broader range of imports. This implies that trade diversion could be substantial.

To be sure, the transatlantic economy's high degree of integration could act as a mitigating factor. For example, Airbus might displace Boeing in the vast Chinese market, but more than one-third of the value-added of an Airbus aircraft is contributed by the US. This is one reason that Mr Trump might choose to prolong the truce with the EU agreed in July.

Ultimately, however, it seems likely that the Sino-American confrontation will shift global trade significantly. This may benefit most of the world's economies, but it will also have serious consequences for the US and China, where consumers and enterprises relying on imported machinery will have to pay more.

The losses are likely to be larger for the US than for China, because Chinese imports from the US include a larger share of agricultural commodities for which alternative suppliers are relatively easy to find. For example, China can import soya beans from Brazil instead of the US, at little additional cost. Moreover, Chinese countervailing measures have been more moderate; there is little prospect of a blanket 25 per cent tariff on US imports.

All in all, the Sino-US trade war may lead to some losses for China, but those losses will likely be dwarfed by the costs incurred by the US itself. Meanwhile, the rest of the world may well have reason to wish both sides a long and fruitful conflict. PROJECT SYNDICATE
