When comparing our purchase volume relative to the market, this quarter, our market share for credit cards stands at approximately 13.7%, up from 12.2% one year ago, with prepaid cards at 15.5%, compared to 12.8% one year ago. As we continue to gain ground, our confidence in our ability to capture additional market share in the future grows. This confidence is grounded in the consistent pace of customer acquisition and the deepening maturity of their relationships with us. Our credit cards and personal loans portfolio, also known as the consumer finance portfolio, reached a significant milestone this quarter now amounting to $15.4 billion and marking a 48% year over year growth. Both segments of our portfolio maintained their growth trends.
Credit card loans expanded by 46% year-over-year, now standing at $12.3 billion. We believe this growth is a direct result of our consistent pace of customer’s onboarding into our ecosystem, and our low and grow credit expanding approach. Furthermore, our personal loans portfolio growth rate accelerated sequentially, registering a 48% increased year-over-year and reaching $3.1 billion. Our personal loan cohorts continue to exhibit the expected behavior, enabling us to increase originations for yet another quarter. We see meaningful opportunities to continue to expand our credit portfolio going forward with attractive returns and robust resilience. As a result, this may intentionally lead to higher delinquency rates. But our goal is to ensure that those will be more than offset by additional revenues and result in higher risk adjusted net interest margins.
Now let’s delve deeper into the breakdown of interest earning loans within our credit card portfolio. Our interest earning installment balance continue its growth this quarter, now constituting 21% of our total credit card loan portfolio. This expansion is a direct result of our strategic commitment to bolstering our transactional financing product portfolio with a special emphasis on PIX financing. This strategy is intended to capitalize on the increasing adoption of PIX in Brazil, where we remain one of the leaders among peak service providers. Over the past year, we have steadily expanded our transactional financial portfolio, and we see its performance reinforce in our belief in its ability to deliver highly attractive risk adjusted rates of return.
This approach not only allow us to monetize our credit card business, and our picks market share, but also unlocks substantial value for our customers. Our personal loan portfolio continues to demonstrate impressive resilience, aligning with our expectations for asset quality and allowing us to steadily sharpen our credit underwriting and expand our origination levels. In the last quarter, personal loan originations saw a 93% year-over-year increase, reached an all time high of R8.9 billion. Furthermore, we have made substantial progress in broadening our lending product portfolio. Year-to-date, we have introduced payroll loans for federal public servants and retirees as well as FGTS-backed loans for the wider Brazilian population. Additionally, we have initiated the offering of unsecured personal loans for our Mexican customers.
While these new products may not have a material impact on origination volumes or on credit portfolio for 2023, we expect them to lay the groundwork for continued growth and an even more resilient credit portfolio in the coming years. Our confidence in our ability to sustain and drive substantial growth in the personal loan segment is underpinned by several factors. This includes our substantial and expanding customer base, our strong underwriting platform, our robust capital base, and our ample liquidity position. Moreover, As of June 30th, around 50% of the outstanding balance of unsecured personal loans in Brazil was already held by news clients, and nearly 40% of the outstanding balance of payroll loans in Brazil is also held by news clients.
In essence, we believe we have significant opportunities to expand our market share in this credit products while selectively targeting our most valued customers. Now let’s turn our attention to funding. Our total deposits continue their growth expanding by 26% year-over-year and reaching $19.1 billion this quarter. This progress indicates another significant strides towards the realization of our objective, which is building one of the most robust local currency retail deposits franchise in the region to support our consumer finance operations across the 3 geos where we operate. Our loan to deposit ratio, or LDR, for this quarter remains stable at 35% with deposit growth showing sequential acceleration. One year ago, our LDR was at 25% indicating our ongoing efforts to optimize our balance sheet, but we believe there is still ample room for additional balance sheet optimization ahead.
