When the Bloomberg Commodity Index (BCOM) was launched in 1998, the architecture made sense for its time. Liquidity in commodity futures was concentrated in North American contracts denominated in US dollars, and the methodology was built accordingly. Twenty-eight years later the way global commodity markets operate and the way institutional investors want to access them has shifted.
The launch of the Bloomberg Global Commodity Singles Indices (BCOM Global Singles) is Bloomberg’s response. The new family of single-asset indices tracks individual futures contracts beyond the 25 commodities in the flagship BCOM, extending coverage across energy, industrial and precious metals, grains, soft commodities, and livestock. The indices incorporate regionally significant and non-USD denominated futures, with contracts sourced from the CME, ICE, and LME.But the significance goes beyond adding more tickers. The launch signals a broader shift in how commodity index providers are rethinking their role, i.e. moving from offering only static and broad benchmarks toward supplying the modular components that institutional allocators increasingly demand.
From Benchmark to Building Blocks
Jigna Gibb, Head of Commodities and Crypto Index Products at Bloomberg Indices, frames the expansion as a response to the way commodity allocation has evolved since BCOM was first conceived.
“The methodology states that contract selection for BCOM will tend to favour those listed in North America and denominated in US dollars,” she tells Market & Alt Data Insight. “So the framework was anchored to where the pools of liquidity were most active three decades ago. Fast forward to today, and we’ve seen much more trading activity across the globe.”
That geographic and currency diversification of liquidity has coincided with a fragmentation in how investors use commodity exposure. Strategic long-only allocations – BCOM’s traditional territory – now sit alongside a growing universe of tactical strategies designed to exploit regional dislocations and thematic trends.
Gibb points to the first quarter of 2026 as an illustration: the TTF-Henry Hub spread widened sharply on divergent supply dynamics, Brent traded at a significant premium to US-delivered Midland crude, and the Murban contract was directly affected by an attack on the Fujairah port. Each of these represented a tradeable dislocation that required granular, single-asset exposure to capture.ETF Issuers Are Driving the Agenda
One of the more revealing details in the launch is that it has been demand-led rather than supply-led. Bloomberg has staggered the rollout, prioritising specific contracts in response to client requests rather than releasing the full suite at once.
“An ETF provider came to us last year and said they were concerned about European inflation and thought German power would be very topical – so we prioritised the launch of German power a year ago,” Gibb says. A similar dynamic played out on the metals side, where an expanded universe of metals was launched to support energy transition-themed products.
That pattern – product issuers pulling index providers toward specific contracts, rather than index providers building and waiting for demand – offers a useful signal about where institutional commodity allocation is heading. It also distinguishes the BCOM Global Singles from a purely analytical exercise: these indices are being built for licensing and product development, not just Terminal-based research.
Engineering Around Liquidity Constraints
The expansion into thinner, more nascent futures markets raises an obvious question about whether these contracts can support institutional-scale tracking. Bloomberg’s answer involves a methodological adjustment: the BCOM Global Singles use a ten-day roll window, double the five-day window used in standard BCOM.
Gibb is candid about the rationale. “When you’re dealing with contracts that are relatively nascent and have lower volume, a longer roll period enhances the available liquidity pool,” she says. The approach acknowledges the constraint rather than pretending it doesn’t exist; a degree of transparency that institutional data and portfolio teams will likely appreciate when evaluating these indices as potential building blocks.
Bloomberg has also drawn on its internal research capabilities to construct thematic products on top of the singles. The Bloomberg Transition Metals Index, launched last year in collaboration with BloombergNEF(BNEF), combines aluminium, copper, zinc, nickel, lead, silver, cobalt, and lithium, with the battery metals capped at one per cent representation. It is an early example of how the singles are designed to feed into broader composite and thematic strategies.
The Composite Is the Real Contest
Bloomberg is not the first to offer single-commodity index families. Both S&P and LSEG have established offerings in this space. Gibb argues the differentiation lies in the BCOM suite of offerings rather than in the singles themselves: a flagship benchmark with over $108 billion in tracking assets to it and its family of indices, approximately 50 per cent market share in broad-based commodity ETFs, the Bloomberg Terminal as a distribution channel, and extended historical data going back to the 1960s for regime-based backtesting.
Those are credible advantages, but the competitive picture will sharpen considerably when Bloomberg launches what it describes as the real next step: a BCOM Global composite, targeted for the end of 2026. That product would position Bloomberg as a direct competitor to S&P GSCI at the broad-based global commodity benchmark level, backed by a wider universe of contracts and the integrated data and research solutions that the Terminal provides.
“A composite would be the right way to bring everything together, and that’s something we’re actively working on with research,” Gibb says. “Watch this space.”
For institutional data teams evaluating commodity index infrastructure, the singles launch is a useful but incremental development. The composite, when it arrives, is where the strategic implications begin.
