WhatsApp has something most other would-be super apps do not: the stickiness of an immensely popular messaging service. And unlike China's WeChat, WhatsApp is a global phenomenon, with large user bases in a diverse array of countries: India, Indonesia, Brazil, South Africa and the United States to name a few. Having eschewed advertising, WhatsApp hopes to monetize all those users with digibanking and e-commerce services. If WhatsApp becomes a global one-stop shop for communication, shopping and banking it will be the only app of its kind.

Not so long ago, Ant Group looked set to build a digital finance empire in Asia. Ant has a foothold, in one form or another, in every major Asian economy. The company has invested in e-wallets across Southeast Asia. It operates fledgling digital banks in Hong Kong and Singapore, the region's two key financial hubs. It is a major backer of India's largest fintech unicorn, Paytm. Ant even has fintech investments in Bangladesh and Pakistan. Yet in retrospect Ant may have overextended itself internationally, confident that its ascent was insuperable even as regulatory problems mounted at home.

December was an eventful month for Australia's neobanks. Xinja's demise made waves, showing that it does not pay to keep building atop a flimsy foundation. Castles in the air must come down. And yet, some Aussie neobanks are thriving. Shortly after Xinja said it would turn in its banking license, Australian Financial Review reported that Judo Bank was set to raise up to AU$200 million from investors, bringing its valuation to AU$1.65 billion.

Afterpay has to be feeling pretty good heading into 2021. It has become one of the largest buy now, pay later (BNPL) firms in the world and is growing fast just as the sector hits its stride. BNPL is not a new idea, but Afterpay has repackaged it neatly: four interest-free installments with no fees at all for customers as long as they pay on time. Retailers are willing to take on the risk of late or missed payments because Afterpay is bringing in more business for them. The company's sales grew 112% year-on-year in November to a record US$2.1 billion. Its share prices have risen roughly 270% to A$113.29 from A$30.63 when the year began.

The Grab-Gojek rivalry is fast becoming the stuff of legend. Barring a merger, those two Southeast Asian decacorns are determined to one-up each other for evermore. The rivalry began with ride hailing and food delivery and has intensified in the fintech sector, the best hope for both firms to reach profitability and provide their deep-pocketed investors with an attractive exit. Following Grab leading a US$100 million funding round in Indonesian e-wallet LinkAja, Gojek spent US$160 million to increase its stake in PT Bank Jago to 22% from 4%. It is Gojek's largest investment yet in financial services.

Taiwan has had no shortage of opportunities to become a regional financial center. Most recently, Hong Kong's business environment declined markedly, prompting calls in Taipei to attract financial business from the former British colony. That will not happen though. Taiwan's regulatory environment is too restrictive. The business that leaves Hong Kong will instead go to Singapore and Tokyo.

In the twilight of 2020, warnings about shaky neobank business models often fall on deaf ears. For most neobanks and their investors, the prevailing business model remains growth first, ask questions later. Perhaps the abrupt collapse of Xinja, an erstwhile high-flying Australian neobank, will give others in the sector pause about their approach. Like most of its peers, Xinja telegraphed extreme confidence about its prospects. Right up until the end, Xinja was cool as a cucumber, assuring the public that a huge investment from Dubai-based investors was on the way. As it turns out, the cash is missing in action. And it is quite a sum.

Political uncertainty has dulled Hong Kong's edge as a global financial center. That much was clear long before Ant Group's IPO came to a screeching halt. The abortive Ant deal signaled that politics could shake Hong Kong's capital markets too. Still, Hong Kong's IPO market remains red hot - just not for fintechs anymore. As Hong Kong draws closer to China, it will assume the role of the country's offshore financial center. That will provide both Singapore and Japan with the chance to win some new business, which will be for the best. Asia is large enough to have multiple financial centers, each with a different role.

South Korea's digital payments market has grown at a brisk clip amid the pandemic. From January to November, contactless payments rose 17% as businesses and consumers shifted to online transactions, according to the Bank of Korea. E-commerce transactions rose 26% during that period. It is against this backdrop that the Korean startup CHAI sees an opportunity for an API that allows online merchants to accept more than 20 payment systems.

Revolut always thinks big, so it is no surprise that the UK neobank unicorn is now billing itself as a global financial super app. Revolut's CEO Nikolay Storonsky spoke about this topic at Singapore's recent Fintech Festival. It was hard not to see the irony there. While Revolut was talking about its super app dreams, Grab-Singtel, Sea Group and Ant Group were mulling how to best use their newly won Singapore digital bank licenses. Revolut was not even in the running for one. It dropped out of the race more than a year ago due to the stringent capitalization requirements.
