When PayPal Holdings Inc (PYPL -2.98%) reported its 2016 fourth quarter earnings, one of the most impressive items was the incredible growth of the popular peer-to-peer (P2P) payment platform, Venmo. In the final quarter of the calendar year, Venmo had processed $5.6 billion in total payment volume, a whopping 126% increase year over year.

In the conference call, PayPal management proudly noted that in December 2016, Venmo had crossed the $2 billion threshold in total payment volume in a single month for the first time. To grasp how quickly the platform is growing, we must remember that it was just earlier in the year when the platform first surpassed $1 billion in a single month.

It's no secret that much of Venmo's growth is coming from younger generations and the app's social media-like qualities has made it a particular hit with millennials. Not surprisingly, the platform's growth has not gone unnoticed by the financial industry. This year, banks are responding by launching Zelle, a jointly backed P2P app that links directly to a consumer's account at one of the participating banks.

What is Zelle?

Zelle is operated by Early Warning, a payment and risk solutions company that is owned by several of the country's largest banks and financial institutions including Bank of America Corp, BB&T Corporation, Capital One Financial Corp., JP Morgan Chase & Co., PNC Financial Services Group Inc, and Wells Fargo & Co. Through partnerships with Mastercard and Visa, most credit unions will also participate in the program.

Zelle's service allows payers to send money to another person using only their email address or phone number as an identifier. Zelle users can sign up with nothing more than a debit card or bank account. Users can both send and request funds. Money will be transferred "within minutes" from one bank account to another -- making it quicker than Venmo's service, which requires users to manually initially a transfer from their Venmo accounts to their banks.

Will this be the death of Venmo? Zelle no!

What most might not realize is that this payments platform has existed since 2011 under the name clearXchange, when it was originally founded by Bank of America, Chase, and Wells Fargo as a P2P service. While the platform gained little traction as clearXchange, the banks are hoping that rebranding, new leadership, and the corresponding marketing campaign will revitalize the service.

The strategy seems to be working. In a recent press release, the service claimed to have "processed more than 170-million person-to-person (P2P) payments in 2016, totaling $55 billion in aggregate transaction value." Not too shabby! 

While some have opined that banks are hoping to kill off Venmo with Zelle's launch, I find that scenario unlikely, to say the least. Zelle's success in 2016 seems to have done little to stunt Venmo's growth last year. What it probably means is that, while the P2P market is not a big profit maker, banks want their account holders more engaged with their own banking products and services than having their customers practically forced to retreat to third-party services like PayPal.

On the surface, Venmo doesn't appear worried about Zelle's imminent entrance. Josh Criscoe, Venmo's head of corporate affairs and communications, recently stated:

"We don't see it as a winner-take-all scenario. We welcome any effort to move folks to more digital payments and move toward the smartphone as the central point of financial life. The common enemy is cash."

Venmo's explosive growth probably also means there is plenty of room for additional players in the P2P market. After all, doling out cash and writing checks are still far and away the leading ways people pay back friends and family members. This gives Zelle and Venmo a long runway of growth ahead.
