Australia is a key market for PayPal in Asia Pacific. The U.S. payments giant has 9 million accounts Down Under - not too shabby for a country of 25 million people. It has a 17% share of what JP Morgan calls the "alternative payments market (essentially non-cards), ahead of Google Pay, Apple Pay and Samsung Pay. But there is a new payments game in town led by firms like Afterpay and Zip. To maintain its competitive edge in Australia, PayPal needs to enter the buy now, pay (BNPL) segment.

PayPal is a payments giant with super app ambitions but a small footprint in Asia. Indeed, although PayPal has been present in many Asian markets for ages, it is not a market leader in any of them. In fact, to date, it is more notable for reducing its presence - exiting the domestic payments business in both Taiwan and India, for instance - than scaling up. Becoming a bigger player in Asia will not be easy for the US$340 billion company, despite its vast resources.

It seems that almost every plucky fintech in the cross-border payments space seeks to challenge SWIFT these days. Airwallex is perhaps the best known. The Hong Kong-headquartered (but Australia-founded) unicorn boldly proclaims that it wants to rejig global payments rails at SWIFT's expense. Then there is Lightnet, which is only slightly less ambitious. Lightnet aims to dominate B2B remittances in Asia with none other than cryptocurrency, which it says will render obsolete traditional global payments methods like SWIFT and Western Union. Lightnet is focused on making cross-border payments more economical by trimming the number of intermediary parties from about five to just the sender and receiver. The company expects costs to be further trimmed as its network grows.

The clock is ticking for a Grab exit. Southeast Asia's most valuable startup has been in business now for almost nine years. It has been losing money that entire time. To be sure, Grab has seen its user base, valuation and revenue grow exponentially over that time. The company has evolved from an Uber lookalike into an aspiring super app betting on digibanking to deliver it from the red ink into the black. That could be easier said than done.

In Vietnam's fiercely competitive e-wallet market, Momo stands out. The company has attracted deep-pocketed backers including private-equity firm Warburg Pincus and Silicon Valley fund Goodwater. Momo has is Vietnam's largest e-wallet by users, with 25 million, which it plans to double in two years. Momo recently completed a mammoth funding round that reportedly raised US$100 million that the company will use for strategic acquisitions and to enhance its app with biometrics technology.

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.

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.

E-commerce is an ideal platform from which to launch a digital payments business. Alibaba figured that out early on, launching Alipay back in 2004. Today, it is hard for any e-wallet to become as dominant as Alipay, especially in a market as competitive as Indonesia. Yet Sea Group's ShopeePay is fast becoming one of Indonesia's most popular e-wallets on the back of Shopee's ascension. Shopee was Indonesia's top e-commerce platform by site visits in 2019 and looks set to repeat that feat this year.

China is strict about gambling, only permitting it in the special administrative region of Macau. Elsewhere in the country, gambling is illegal. China's restrictions on gambling cover cyberspace too. Yet that ban is hard to enforce, especially as the pandemic has pushed so much economic activity online. According to a recent Caixin report, some of China's largest internet companies have become party to the illegal online gambling ecosystem. The internet giants may not be privy to the illicit transactions, in some cases because of inadequate due diligence.

After years of solid growth, global remittance flows are set to shrink in both 2020 and 2021, weighed down by the pandemic and its associated economic fallout. Asia, one of the fastest growing regions for remittances in recent years, will be one of the hardest hit regions, the World Bank estimates. Remittances in East Asia and the Pacific are projected to fall by 11% in 2020 and 4% in 2021. In South Asia, remittance flows are predicted to fall 4% this year and 11% the following year.
