Aluminum traded on the London Metal Exchange slipped to about $3,594 a tonne on Monday, easing back from the more than four-year high of roughly $3,790 it touched on June 2. The decline came as a stronger U.S. dollar made the metal more expensive for buyers using other currencies, briefly cooling a rally that has run for months.

Here is the simple version. Aluminum is priced in dollars. When the dollar gets stronger, the same bar of metal costs more for buyers in Europe, China, India and elsewhere paying in their own currencies. That extra cost tends to slow demand and pressure prices lower. That is most of what happened this past week.

The dollar climbed after a strong U.S. jobs report. A healthy labor market raises the odds that the Federal Reserve keeps interest rates elevated if inflation remains stubborn. Higher U.S. rates tend to attract investment into dollar-denominated assets, strengthening the currency and weighing on commodities priced in dollars. That chain reaction, not any easing of overseas tensions, is what knocked aluminum off its peak.

It is important to understand what did not cause the pullback. Supply concerns that have supported aluminum prices in recent months have not disappeared. Traders continue to monitor disruptions affecting energy markets, shipping routes and raw-material supplies, all of which can influence the cost and availability of aluminum around the world.

There is also continuing concern about access to bauxite, the ore used to make aluminum. Export restrictions and supply-chain uncertainties in key producing regions have added another layer of pressure to the market. When raw materials become harder or more expensive to move, the effects are felt throughout the aluminum supply chain.

For all the day-to-day swings, the bigger picture remains a market trading near multi-year highs. The recent decline represents a pullback from a sharp rally rather than a fundamental change in direction. Prices remain well above levels seen earlier in the year.

The business impact extends far beyond commodity traders. Aluminum is a critical input for automobiles, beverage cans, construction materials, packaging, electrical transmission lines and aircraft manufacturing. When prices remain elevated for extended periods, those costs eventually work their way through factories and into consumer products.

Manufacturers that consume large amounts of aluminum often try to lock in supply contracts ahead of time, but prolonged price increases can still pressure profit margins. Beverage makers, automakers and industrial manufacturers all keep a close eye on aluminum markets because the metal is embedded in so many everyday products.

The currency story matters for Americans as well. A stronger dollar can make imported goods cheaper for U.S. consumers while making American exports more expensive overseas. Aluminum’s recent move is one example of how expectations about Federal Reserve policy can ripple through global markets and eventually affect businesses and households alike.

What happens next will likely depend on two competing forces. On one side, a strong dollar and the possibility of higher-for-longer U.S. interest rates could continue to pressure commodity prices. On the other, ongoing supply concerns and tight availability of key materials could provide support.

This week, the dollar gained the upper hand. Over the longer term, however, supply conditions may prove to be the more important factor in determining where aluminum prices go next.

For now, aluminum remains near multi-year highs, underscoring just how strong the market has been despite the recent pullback.
