Jorge, Thanks for the question. This is Lago. I think we are very pleased with the evolution of the total portfolio growth that we have presented. I would point you to Slide 36 of our earnings presentation, in which we provide more details on the breakdown between personal loans and credit card growth. And one of the things that you will note is that irrespective of the seasonality, we have been posting fairly robust growth in our credit card book.
In fact, by the end of the first quarter of 2024, we estimate that our market share in cards, in general, has reached about 15%, 1-5, which would place Nubank as the second credit card issuer in the country, and we continue to acquire market share quarter after quarter. Now notwithstanding the robust growth in credit cards, personal loans is actually outpacing credit cards, and that has happened over the past 5 quarters in a row. And you will note that in the first quarter of 2024, personal loans grew by 25% on an FX-neutral basis. Credit card grew by 8%.
Now to your question, within personal loans, I would then refer you to -- let me take a look here to Slide 15, in which you can see the evolution of the originations of personal loans. You will see that over the past 4 quarters, it increased from BRL 6 billion per quarter to more than BRL 12 billion. So we almost doubled the originations. You see that still, the primary driver of this absolute growth is with unsecured personal loans. The eligibility of which continues to expand across our customer base.
If you take a look at the total personal loan -- unsecured personal loan pie in Brazil, which accounts for the second or third largest profit pools in the country, our customers alone, as of the end of the fourth quarter, accounted for about 43% of the entire loan book in Brazil. And we still have no less than 8% market share there, so we have plenty of room to grow.
Now at the beginning of the second half of 2023, we expanded in secured personal loans, which encapsulates consignado or public payroll loans, FGTS and investment-backed loans. Public payroll loans and FGTS account for about 90% of our total originations, with investment-backed loans accounting for 10%. We expect that the originations of secured personal loans will continue to outpace the originations of unsecured personal loans as we increase the collateral agreements that we have as of today.
So today, we offer public payroll loans, Jorge, primarily to INSS and SIAPE, which are now federal public servants and pensioners and retirees, which account broadly for 50% of the target market of secured personal loan in Brazil. We will be increasing our scope to add armed forces in many states and municipalities, and we hope to reach about 75% of the target market by the end of 2024.
