Swiss Gold Boom Threatened By Imminent U.S. Tariffs On One-kilogram Bars

Reading Time: 2 minutes

Swiss gold smelters have experienced a surge in business recently, leveraging a lucrative price differential between US gold futures and the London spot price. However, this profitable chapter is at risk of closing as new punitive tariffs may soon reshape the landscape of gold trading.

This gold transfer bonanza enabled Swiss refineries to capitalize on a unique arbitrage opportunity by remelting hefty 12.5-kilogram bars—standard in Europe—into the smaller one-kilogram bars preferred in the US. Acting as a gold processing hub, Switzerland has been remelting these substantial bars into packages roughly the size of a smartphone, catering to eager American buyers.

While the increased trading volume painted a rosy picture in trade balance figures, the reality of these transactions was clouded by a crucial detail: although these bars were counted as exports to the US, they initially entered Switzerland as imports.

Pricey Tariffs Threaten Low-Margin Business

Recent reports from the Financial Times suggest that this booming business may be upended by new tariffs set to be imposed by the US. If the information holds true, the introduction of a blistering 39 percent tariff on Swiss goods, specifically targeting one-kilogram gold bars, stands to catch the industry off guard. This decision is rooted in a ruling letter issued by US Customs and Border Protection on July 31, which classifies these gold bars under a customs code subject to steep levies.

Industry insiders had anticipated that one-kilogram gold bars would sidestep the notorious “Trump tariffs,” given that they dominate trading on Comex, the world’s leading gold futures market, making up the bulk of Swiss gold exports to the US.

Gold Futures React to New Tariff News

In the wake of the tariff reports, gold futures on the Comex shot up to a notable high of $3,534 per troy ounce, demonstrating the market’s sensitivity to regulatory changes. The tariff announcement has been described as yet another stumbling block for Swiss gold trading with the US. Christoph Wild, president of the Swiss Precious Metals Dealers and Processors Association, expressed concerns about meeting the burgeoning demand for gold amidst these new obstacles. “Our prevailing thought was that gold melted down by Swiss refineries and exported to the US would be ship-free,” Wild remarked. “However, tariff classifications for different gold products lack clarity.”

Over the twelve months leading to June, Switzerland exported a staggering $61.5 billion worth of gold to the US, underlining the scale of the trade relationship at stake. Experts from Lombard Odier argued that this situation warrants a nuanced perspective from the US government, urging them to consider the temporary nature of such commodities in their broader trade negotiations. Yet, so far, the Trump administration appears primarily focused on the total value of imports, without accounting for the complexity of specific product classifications.
