Open Finance Use Cases: Aggregation, Credit Decisioning, Pensions and More
One-line subtitle: what open finance actually unlocks — and how teams get the data when official APIs fall short.
============================
INTRODUCTION
--------------------
Open finance is bigger than open banking. It spans banking, investments,
pensions, insurance, credit and tax — and its value comes from what the
data unlocks, not from the regulations themselves. Yet official,
consent-based APIs and aggregators still reach only a fraction of the
world's finance apps. Open Finance Studio maps the regulations, the API
standards (FDX, FAPI, OAuth2/OIDC) and the aggregator market — and where
coverage gaps remain, builds authorized, protocol-layer data-export
integrations for the specific apps you need. Full overview:

KEY USE CASES COVERED
--------------------
The use-cases hub walks through six concrete domains — what data each
requires, how regulation and standards help, and how teams fill the gaps:
Investment data aggregation — holdings, positions and portfolio
transactions across brokerage and retirement apps; the domain official
APIs reach last.
Credit decisioning — underwriting on real cash-flow data (balances,
income, transaction history) instead of, or alongside, bureau scores.
Pensions dashboards — consolidating a customer's pension pots across
many providers; a textbook open-finance problem, and one of the least
served by official APIs.
Insurance data — policies, premiums, coverage and claims; among the
last data types open finance reaches, now opening under new regulation.
Account aggregation — consolidating balances and transactions across
many banks and apps; the original open-finance use case, where
long-tail coverage decides success.
Treasury and cash visibility — knowing your corporate cash position
across every bank and account in near real time.
WHAT CAN BE INTEGRATED
--------------------
For the banking, investing, lending or insurance app you actually need
data from, Open Finance Studio delivers documented data-export
integrations built on authorized, protocol-layer analysis:
Balances and income data for credit decisioning and underwriting
Transaction history and cash-flow records
Investment holdings, positions and portfolio transactions
Pension and retirement account data across multiple providers
Insurance policies, premiums, coverage and claims data
Multi-bank cash positions for treasury and cash management
WHY AUTHORIZED INTEGRATION
--------------------
Coverage: regulations and aggregators reach only part of the market —
authorized protocol-layer integration covers the long tail of apps
official APIs miss.
Compliance: consent-based and authorized, aligned with open-finance
standards such as FDX, FAPI and OAuth2/OIDC.
Control: the documented data-export integration runs in your own
environment — no dependency on a third-party aggregator's roadmap.
Maintainability: a documented integration is far easier to operate
and audit than fragile screen-scraping or unofficial capture.
WHO IT IS FOR
--------------------
[1] Lenders replacing or supplementing bureau scores with cash-flow data
[2] Wealth and personal-finance platforms aggregating across providers
[3] Corporate treasury teams needing near-real-time cash visibility
CONCLUSION
--------------------
Open finance matters because of what it unlocks — but only if you can
actually reach the data. Where official APIs and aggregators fall short,
authorized, protocol-layer integration closes the gap for the specific
apps your business depends on. Explore all six use-case guides and learn
