How big those are depend on whether this is a temporary or longer-term situation and how long the very recent changes in exchange rates and interest rates persist.”He pointed out that a strong dollar makes U.S. exports more expensive to the rest of the world and that a widely held belief in the agricultural industry is that trade and a weak dollar are good for U.S. agriculture.Still, agricultural exports to the United Kingdom amount to a very small portion of U.S exports worldwide, Abbott said. In 2015, the United States exported $8.3 billion in corn globally but only $62,000 of the crop to Britain. Of the $18.9 billion worth of soybeans the United States exported worldwide, $76 million of that went to Britain.Of the $133 billion in overall U.S. agricultural exports, $1.8 billion went to the U.K. Exports of what the U.S. Department of Agriculture calls “consumer-oriented products,” including wine, nuts, fruits and vegetables, meat and dairy products, amounted to $62 billion worldwide, $1.1 billion of it to the U.K. Wine led in that category with U.S. exports of $282 million to Britain.The Britains’ vote of June 23 drew more attention to the issue of globalization versus nationalization — essentially open or closed markets — said Mike Boehlje, distinguished professor of agricultural economics. Supporters of the referendum to withdraw contend that the influence and sovereignty of Britain has suffered under the EU’s trade and economic regulations and its policies on immigration and the free movement of people within the 28 European countries in the bloc. Similar issues have come up in the current U.S. presidential election campaigns.“Generally, agriculture is much more dependent on international trade than other parts of the economy,” Boehlje said. “Globalization is important to U.S. agriculture to keep markets open to access.”Boehlje said openness also is important to agriculture for immigrant labor it needs and for sharing of innovations that promote growth.“These are probably the more important longer-term issues,” he said. “We don’t know what the answers are yet.”The economists agree that economic ramifications of a European Union without Britain need time to play out. Until they do, thee will be uncertainty.
