The new year brings an addition to a commodity index tied to an estimated $110 billion in assets,1 as the Bloomberg Commodity Index2 added lead to the fold in January. It is relatively rare to add/subtract a commodity to the index because inclusion decisions are made based on five-year average liquidity and global production data. Liquidity comprises two-thirds of the weighting based on five-year average relative trading volume. Global production accounts for one-third of the weighting based on five-year annual average production. There are exceptions, of course. For example, natural gas uses US production data instead of the global output, as natural gas is not yet a global market. Also, utilizing only yearly gold production would underweight gold's importance to the global economy because 85% of all gold mined is held in central banks and as jewelry.3 Without adjusting for this, cattle would have an allocation weight four times larger than gold even though gold prices affect the global economy more than cattle prices.
Why is lead important?
Eighty-eight percent of lead demand comes from battery manufacturers.4 Electric vehicles have a lead-acid battery to power security systems, door locks, sunroofs, and other auxiliary systems independent of their main battery systems. Lead batteries are also prevalent in low-cost E-bikes, scooters, skateboards, and hoverboards due to their cost and durability advantages. Elsewhere, the cost advantage of lead batteries shows itself in grid-scale batteries. There are many lead-based grid-scale battery systems, including the wind, water, and solar-powered microgrid in Eigg, Scotland. Other such systems include the Via Verde 222-unit sustainable residences microgrid in New York City,5 the power system for Alcatraz Island tourist operations, solar microgrids at the Missouri University of Science and Technology, a site in Rutland, Vermont that’s the first solar microgrid funded by the U.S. Department of Energy, and solar microgrid installations in Tanzania and Nigeria designed to provide electricity to remote communities not on the grid.6
Is lead recycled?
Yes, nearly 90% of lead-acid batteries are recycled.7 That's good because all 1.3 billion automobiles on Earth have a lead-acid battery. According to the International Lead and Zinc Study Group, lead demand is forecast to rise by 1.4% in 2023 to 12.60 million tons.8 The same industry group expects refined lead supply to rise by 1.8% in 2023 to 12.56 million tons.
The Bloomberg Commodity Index is updated yearly in January, after which the constituent weights float via market value changes. Lead will begin the year as a 0.9% weight in the broad Bloomberg Commodity Index, becoming the 24th commodity in the index, and a 5.8% weight in the Bloomberg Industrial Metals subindex,9 joining copper, aluminum, zinc, and nickel.
Copper recently topped $9,000 a metric ton for the first time since June 2022. Other industrial commodities such as zinc and aluminum have started the year with price gains as China’s reopening foretells higher demand while exchange inventories remain lower than average.10
