iPath US Treasury 5-year Bull ETN (DFVL) is an exchange-traded note issued by Barclays Bank PLC that provides exposure to the performance of the Barclays 5Y US Treasury Futures Targeted Exposure Index; the ETN seeks to capture returns from a decrease in the yields available to investors purchasing 5-year U.S. Treasury notes through a notional rolling long investment in 5-year U.S. Treasury note futures contracts. Launched in 2011 and listed on NYSE Arca, the product targets investors seeking leveraged bullish exposure to U.S. Treasury yields in the fixed income derivatives segment; it operates globally but primarily serves U.S. markets with no physical assets or subsidiaries as it is a senior unsecured debt obligation of Barclays Bank PLC, headquartered in London, United Kingdom. The ETN was delisted from exchange trading on October 29, 2019, due to low assets under management and market conditions, transitioning to over-the-counter trading thereafter with minimal shares outstanding. No recent partnerships, funding rounds, acquisitions, new product launches, or strategic expansions specific to DFVL have occurred in the last 1-2 years, as Barclays continues to manage its iPath ETN series amid ongoing issuer calls and redemptions for select products in 2025.
