Benjamin Jackson
President, Intercontinental Exchange at Intercontinental Exchange
Thank you, Warren, and thank you all for joining us this morning. Please turn to slide eight. I would like to first welcome the Black Knight team to their first ICE earnings call. While it has been less than two months since we closed on the acquisition in early September, we've been very impressed by the collaboration between our teams during this short time, a testament to the talent of our respective employee populations and our shared entrepreneurial cultures. Similar to our exchanges and fixed income businesses, Black Knight integrated into our ICE Mortgage Technology network, a network that thrives by offering a value proposition that aligns growth with efficiency gains that we bring to our customers.
As we have seen across our network in futures and fixed income, these efficiency gains are best achieved through harnessing unstructured data to create mission-critical information, seamlessly linking participants to that information and ensuring that the network technology underpinning are of the highest quality and security. It is the execution of this value proposition that often propels an analog to digital conversion of an industry, and it is a blueprint we've applied across all our businesses. A number of years ago, we saw the importance of investing in an energy platform that is truly global, one that better serves the needs of an evolving and growing commercial customer base.
Today, as trade dynamics evolve and become increasingly complex, customers are not only seeking liquidity in the major gold benchmarks, but also in products that provide for greater hedging pursuit. Our global oil complex spans over 700 products, including locational spreads, product spreads and refining spreads. These products are built off of our benchmark contracts, such as Brent crude oil and gas oil. Driven by the breadth of our commercial customer base, we have become the natural home for liquidity in these products with open interest in our oil complex up 26% year-over-year through the end of October, including a 28% increase in our other crude and refined products.
In our natural gas markets, we began investing in the globalization of these markets over a decade ago. Today, our European TTF and Asian JKM gas complexes continue to grow and reach important milestones as they evolve into global gas benchmarks. In the third quarter, the number of participants in each market grew double digits year-over-year and TTF reached another quarter of record volumes. This strong performance helped drive record revenues across our natural gas complex through the first nine months of 2023, up 37% year-over-year.
In addition -- interest trends for TTF and JKM remained strong through October, up 58% and 19% year-over-year, respectively. This strength continues to underscore the significance of our contracts to the price formation of global natural gas. We are well positioned to both benefit from the near-term volatility and the long-term secular growth trends occurring across these markets because we operate a global gas market with benchmarks across North America, Europe and Asia. In our environmental markets, we recognize the importance of carbon price transparency over 10 years ago by acquiring the Climate Exchange in 2010 and building around those leading markets to develop a global environmental business. As we look out over the longer term, corporates and market participants remain committed to environmental policy to reduce carbon emissions. This is illustrated by continued growth in active market participants, up 9% year-over-year.
Importantly, because we offer one of the broadest suites of environmental products across the carbon cycle, we remain excited about our position to serve customers as they navigate the journey to clean energy and as the demand for transparent pricing in carbon grows. In summary, these cleaner energy sources combined, including global natural gas and environmental make up over 40% of our energy revenues today and have grown 17% on average over the past five years, including a 30% growth year-to-date. As the clean energy transition continues to introduce new complexities, uncertainties and volatility to energy markets, our global environmentals, alongside our gas and oil complexes, will provide the price transparency across the energy spectrum needed to manage these evolving risks.
Moving to our Fixed Income and Data Services business. As fixed income markets electronify and passive investing grows, our comprehensive all-weather platform continues to generate compounding revenue growth, up 7% year-to-date. Investments we've made to enhance content and functionality across our other data and network services business continue to pay dividends. Year-to-date, this part of our business is up 7%, driven by strength across our desktop, derivatives analytics and feed offerings as customers continue to modernize workflows. Within our desktops business, the investments we have made to reduce friction across the workflow have contributed to double-digit revenue growth year-to-date, along with double-digit growth in the number of users that connect to our ICE Chat platform.
Similarly, within our consolidated feeds business, investments we've made to elevate and enhance our offering have led to accelerating adoption by large financial institutions. This has directly contributed to high single-digit growth in this area year-to-date. In addition, we continue to see strength in our index business driven by double-digit growth in ETF assets under management as of the end of the third quarter, with now over $0.5 trillion in assets selecting ICE indices as the passive benchmark.
As we move forward, we will continue to build on our track record of adding efficiencies and bringing transparency to opaque asset classes, leveraging our mission-critical data assets and market-leading technology. Turning now to our mortgage business. Like what we saw in the commodity markets 20 years ago, there's an analog to digital conversion occurring in the U.S. residential mortgage industry. Critical to our ability to execute on this opportunity is our network, one that in combination with Black Knight, spans from consumer acquisition all the way through to the secondary market.
In the third quarter, our mortgage business once again outperformed the broader industry that experienced a nearly 20% decline in origination volumes. This continued outperformance is a result of executing against our strategy of leveraging our mission-critical technology and data expertise to accelerate the analog to digital conversion happening in the industry. Part of that strategy is intentionally shifting more business to recurring revenue, particularly within our origination technology and data and analytics business. And during the third quarter, of the Encompass customers that came up for renewal, roughly 60% increase their base subscriptions.
Importantly, where customers decline in subscriptions, the trade-off is a higher per closed loan fee, which will provide an uplift in transaction revenues when the market returns. In addition, part of our thesis has been at clients that have origination businesses, combined with servicing businesses, we want to bring together a complete front-to-back experience for their clients through one trusted platform provider. As mentioned last quarter, JPMorgan Chase has selected Encompass for their loan origination system across all channels and has implemented or is implementing our data and document automation platform. These wins are on top of a long-standing, great relationship with MSP for servicing, which now positions us to provide a platform to help facilitate their front-to-back experience for their clients. And since we closed on Black Knight, I am pleased to share two new wins along the same lines.
First, M&T Bank has now selected Encompass to replace their existing loan origination platform and has added our data and document automation platform on top of the existing MSP relationship for servicing, again, positioning us to provide our platform to support the front-to-back experience for their clients. The second new win is with Fifth Third Bank. We have cross-sold MSP and several data and analytics products to Fifth Third Bank, an existing IMT customer, our consumer engagement solutions and all regs product.
In summary, these are major wins for us and serve as a validation of our vision with large clients bringing together a complete front-to-back experience for their clients through one trusted platform provider. The relationships with these great customers are models we plan to replicate with many more. Increased workflow efficiency through continued electronification is a secular trend we believe will continue through a variety of mortgage origination environments. This trend gives us confidence that we can grow the business that today is only a fraction of the $14 billion addressable market that is in the early days of an analog to digital conversion.
With that, I'll now turn the call over to Jeff.
