Global Context

Globally Banks have started partnering with Fintech to build innovative products and services with more than 50+ such initiatives having raised more than $2 Billion

  • DBS Bank launched the world’s largest API Platform consists of 155 API’s in over 20 categories
  • PSD2 is a regulatory mandate to standardize and make an interoperable card, internet and mobile payments. By Jan 2018, all FI in the 28 EU members needs to be PSD2 compliant
  •  CMA9: Open Banking as a directive covering only the top 9 banks in the UK
  •  According to Forrester Consulting Total Economic Impact™ (TEI) study, there will be 50% to 90%+ improvement in API management productivity, freeing up time to focus on innovation


Open APIs will enable banking organizations to gather actionable data from various internal and external sources, including buying habits, financial goals, risk tolerance and even social interactions.

  • Insight derived from this API will enable more proactive (and accurate) multi-channel marketing, moving from reactive sales pitches to proactive solutions and advisory services.
  • The ability to apply Artificial intelligence(AI) in analyzing these API calls (stateless), given they can amount to huge volumes over time can be a great source of learning for AI tools.

 It will respond to the customer desires of “Know me,” “Look out for me” and “Reward me” and thus expected to greatly improve the customer experience which currently lacks personalization and real-time engagement.
