We also generated strong year-over-year growth in ADV in our combined emerging markets and eurobonds product areas of 9% in September, driven in part by record levels of emerging markets hard currency trading ADV, which increased 13%. Additionally, in September, we set a new record for our single highest credit trading volume day ever on the platform on the last trading day of the month. With our new initiatives in the client-initiated channel, block trading ADV in emerging markets and eurobonds increased 35% and 41%, respectively. In the portfolio trading channel, we delivered record U.S. high-yield market share of 25.9%. The growth in these new initiatives is being driven by the technology modernization that we are delivering across U.S. credit, eurobonds and emerging markets.”\n\n\nSelect Third Quarter 2025 Highlights* (See tables 1-1C and table 2)\n\n\nWe continued to show solid progress year-over-year with our new initiatives across the client-initiated, portfolio trading and dealer-initiated channels.\n\n\nClient-Initiated Channel\n\n\n\n10% growth in block trading ADV, including 20% growth in emerging markets and 58% growth in eurobonds block trading ADV.\n— Cumulative trading volume from our targeted block trading solution is now approximately $10.1 billion.\n\n\n\nPortfolio Trading Channel\n\n\n\n20% increase in total portfolio trading ADV to $1.4 billion, with record U.S. high-yield portfolio trading ADV of $341 million.
