Indonesia is one of the most compelling growth stories in Asia, with GDP expected to reach
$1.55 trillion in 2026.
It’s also one of the most complex consumer markets, spanning 6,000 inhabited islands, 300 ethnic groups and 700 languages, and has one of the largest unbanked populations in the world, with
only 56% of adults
holding a formal bank account.
But change is afoot in the country’s banking sector to address the low percentage of the population holding a bank account. A critical pillar of the
Golden
Indonesia Vision, a blueprint to attain advanced economy status by 2045, is financial inclusion, which aims for 98% inclusion to foster equitable economic growth. This is pushing banks to
build digital experiences for people who have never set foot in a branch.
In addition, the regulatory environment has paved the way for digital-only banks, opening up financial services to foster access and competition.
Blueprint 2030
is pushing for deeper integration across banking, fintech and e-commerce, with open banking as the connective tissue. The central bank’s
Project Garuda
is piloting the Digital Rupiah, a programmable central bank digital currency designed to improve cross-border payments and regional interoperability.
The direction in Indonesia’s financial services sector is clear: openness, interoperability and speed. For banks, that is both a regulatory obligation and
a great opportunity. However, the banking infrastructure required to capture this opportunity is lacking.
Incumbent banks must modernise their digital channels quickly to meet changing regulatory requirements, as well as survive increasing competitive pressure
from digital challengers. But they can’t build from scratch quickly enough, and large vendors are either too expensive, too slow, or simply not built for the Indonesian market.
This is where decoupled architecture has a decisive advantage. When the customer experience layer operates independently from the core banking system, banks
can move at the speed of the market without waiting for a vendor’s release cycle.
Using this approach, Indonesian banks don’t have to choose between moving fast and getting it right. They can go live with a modern customer experience in
three to nine months and modernise the underlying infrastructure progressively, at their own pace, without a big-bang replacement that puts the entire business at risk.
But this requires architecture that is truly decoupled, where changes to the front-end experience won’t require changes to the core, and vice versa.
The institutions that succeed in this new environment will be the ones with platforms that can launch a digital experience in months, integrate with alternative
ID and credit data sources, and build lending or payments products designed for customers who have never had a bank account. They will have platforms that embed localisation from the start, not bolted on at the end, and where the customer experience can be
adapted without touching the underlying banking logic.
That is the infrastructure that closes the banking gap.
The institutions that get there first will not need the biggest budget. They will need the right platform – one that gives each of them the freedom to build
for their specific context without starting from scratch every time.
