To make sure we understand where this story goes, let’s see how the digital finance market appeared and developed.
The Growth of the Fintech Market and Digital Banking Industry
The fintech sector has seen more twists and turns than a prime-time soap opera, and with the same level of drama. Here are some snippets of numerous banking software development and general fintech industry twists.
A Timeline of the Fintech Explosion
- 2008. The Global financial crisis. Traditional banks lost the ground and fintech startups got their heads up, looking to capitalize on the overall confusion and bring innovation.
- 2013. Bitcoin’s price gets to $1,000 for the first time, starting the good, the bad and the ugly of the cryptocurrencies and blockchain technology era. Suddenly, everyone and their grandma wanted in on “magic Internet money.”
- 2015. China’s Ant Financial, the behemoth behind Alipay, reaches $45 billion value. West gets reminded once again that fintech is not just a buzzword, it’s a lucrative industry. And it’s time to move fast.
- 2018. Global fintech investments double to a whopping $55 billion. Everyone wanted a slice of the fintech pie.
- 2019. Digital-only banks like Revolut, Monzo, and N26 start gaining traction. They operate without any brick-and-mortar branches and challenge the big traditional banks with their user-friendly services and low fees.
- 2020. The COVID-19 pandemic forces everyone online. Digital payments and neobanking see a massive boost as people avoid physical contact. Fintech solutions go from being a nice-to-have to essential.
- 2021. Decentralized finance or DeFi takes off. Platforms that let people lend, borrow, or trade without middlemen grow popular. By year-end, DeFi has over $40 billion in assets, showing the world that blockchain’s potential goes beyond just cryptocurrencies.
- 2022. Fintech booms in places like India, Brazil, and Nigeria. New startups and apps pop up, giving many people their first taste of modern financial services, bridging the gap left by traditional banks.
- 2023. Governments and institutions worldwide start setting rules for fintech to make sure it’s safe but still innovative. The world starts seeing fintech not just as a trend, but as the new norm in finance.
And here we are, strategizing about banking software you want to develop that hopefully will disrupt the market and make such a list in a few years. What should it get rid of not to bring the cons of traditional banks into the new world? Let’s see.
What Was/Is Wrong with Traditional Banks?
- Legacy systems. While fintechs were built for the digital age, many banks still relied on technology that was older than the first “Die Hard.” Some of them still are.
- Risk aversion. Banks, with their stringent regulations and conservative nature, often ignore innovation. In the effort to increase security, they also don’t invest in state-of-the-art sec systems and quality tests, jeopardizing account safety.
- UX. If banking apps were rated on user-friendliness, some apps rolled out by traditional banks would rank just above “trying to assemble IKEA furniture blindfolded.” In contrast, modern fintech solutions are designed from scratch with the user in mind, prioritizing seamless experiences over bureaucratic hurdles.
Truth to say, big legacy financial institutions catch up rather fast. They cannot act fully like startups and smaller companies, but they successfully incorporate some of the approaches to their benefit:
“A larger organization that understands its processes and systems can make more significant releases. For example, a big legacy bank wants fintech to engage more with users. They know how the system works; it is just a question of putting a user-friendly Front-End on.
While a startup — new and fresh, something no one has seen before, needs constant checks on where and how to evolve. Big financial players use MVP to show what is going on, and startups use MVP to learn and define where they are going.”
In essence, while traditional banks were busy fumbling with outdated tech and red tape, fintechs were sprinting ahead, capitalizing on modern tech and changing consumer expectations. It’s like comparing a horse-drawn carriage to a Tesla. And we all know who wins that race.
