We have to grow by delivering more for our customers and clients. We have to grow by managing risk well. And, our growth must be sustainable. Sustainable means we have to share our success with our communities, we have to be a great place to work for our teammates, and we have to drive operational excellence. This creates the ability to reinvest the savings back into our team, our capabilities, our client experience, and our communities and shareholders.
The first tenet of responsible growth is that we have to grow, no excuses. Each of our businesses continue to grow. Over the last four years, deposits have grown 4 percent and loans across all our business segments have grown 6 percent on average. Our growth in client deposits funds our loan growth across all of our businesses and enables us to continue to grow net interest income, even if further interest rate rises fail to materialize.
We believe we have the best consumer, small business and wealth-management franchise in the country. We serve more than one in three U.S. households and more than 9 million business-owner clients. We see continued growth in our digital and mobile channels, with 37 million digital banking users; nearly 27 million are active mobile banking customers.
Our Global Banking business works with virtually every company in the S&P 500. Global Banking delivers solid and recurring profitability. Recognizing the businesses we serve are the engines of the economy, we bring the broadest array of solutions, both domestic and international, to our clients to help companies grow, improve cash flow and invest for the future.
Turning to the institutional investors we serve, our Global Markets business is one of the most capable platforms in the world. This business provides capital to companies necessary for growth and serves many of the world’s largest institutional investors who manage savings and investments through pension and retirement funds. Our presence and global reach in fixed income and equity products allow us to provide them access to investment opportunities.
As a financial services company, risk is inherent in all of our business activities. Managing risk well is fundamental to our business, and we strive to be the very best at managing all types of risk, and to do so in a responsible manner that serves our clients, shareholders, and communities, and helps the economy grow.
Whether investing in a small business, making a credit decision, or preventing fraud, our work calls for sound judgment and a commitment to doing what’s right for our customers, shareholders, and communities. Our culture emphasizes that we are one team, and we have a shared responsibility to manage risk well, act responsibly, and escalate issues so they can be addressed proactively.
Our Risk Framework, together with our purpose, is the foundation of our culture and describes our approach to managing risk well so we can run our business and grow responsibly. The Risk Framework sets forth clear ownership and accountability for managing risk across the company to ensure that we maintain strong risk-management discipline.
