How Do Shipping Costs Affect the U.S. Trade Balance?

Voltic's approach to lowering shipping costs could make U.S. trade more competitive, but lower costs do not automatically improve the trade balance. Cheaper freight can help exporters reach overseas customers at lower delivered prices. The same cost reduction can also make imports cheaper, so the net effect depends on how exports and imports respond. The proposed estimate assumes that a 10% reduction in trade costs raises trade volumes by 4% to 5%. Scaling that relationship linearly to a 25% reduction would imply roughly 10% to 12.5% more trade. That result describes total trade activity, not the trade balance. Exports and imports could both rise while the deficit remains unchanged or expands. A $150 billion to $200 billion annual current-account improvement would therefore depend on strong export responsiveness, overseas demand, exchange rates, production capacity, and the share of freight savings passed through to buyers. It is not a fixed result and should not be described as a Voltic projection. The specific 2023 OECD source for the 4% to 5% elasticity could not be verified. The dollar range also lacks a documented model connecting lower shipping costs to the U.S. current account. Both figures should remain labeled as scenarios until the underlying study and calculations are available.
