iPath Bloomberg Natural Gas SubTR ETN B (GAZB), issued by Barclays Bank PLC, is an exchange-traded note that provides exposure to the Bloomberg Natural Gas Subindex Total Return, which tracks the performance of natural gas futures contracts traded on the New York Mercantile Exchange, including Henry Hub futures; the ETN aims to reflect the total return of the index, adjusted for the investor fee, without direct investment in physical commodities or futures positions. The product offers investors leveraged access to natural gas price movements through a senior unsecured debt obligation maturing in 2037, with no principal protection and full exposure to commodity volatility and Barclays' credit risk; it trades on NYSE Arca under the ticker GAZB, alongside the related GAZ series. Barclays Bank PLC, headquartered in London, UK, and founded in 1690, operates globally across investment banking, wealth management, and structured products, including the iPath ETN suite covering commodities, volatility, and equities.
The ETN belongs to Barclays' iPath Series B ETNs, focused on commodity subindices for targeted sector exposure, serving institutional and retail investors seeking natural gas market participation without operational complexities of futures trading; it targets markets in the United States primarily, with listings on U.S. exchanges. Recent operational changes include Barclays' full redemption of the closely related iPath Series B Bloomberg Natural Gas Subindex Total Return ETN (GAZ) on June 14, 2023, following suspension of trading and a cash settlement based on the closing indicative value, reflecting strategic portfolio adjustments amid low liquidity and premium/discount issues. In August 2022, Barclays resumed issuances and sales of GAZ and other suspended iPath ETNs after SEC filings and rescission offers addressing paperwork compliance, stabilizing secondary market dynamics. As of June 2025, Barclays exercised issuer call options to redeem additional iPath ETNs (excluding GAZB specifically named), amending indentures via tender offers to enable discretionary full redemptions on June 25, 2025, signaling ongoing rationalization of legacy ETN lines.
