How Market Researchers Use Diversified Financial Services Data
Market researchers use diversified financial services data to size deposit markets, profile advisory firms and benchmark national financial systems. The working stack pairs FDIC Summary of Deposits' 2.8M-plus branch-year rows, SEC IAPD's 15,000-plus adviser records and World Bank WDI's 72 Financial Sector indicators - and 17 of the 19 primary datasets Datadory catalogs here are free.
1,744 datasets. Pick your catch.
What does a financial-services market study actually need?
Four evidence layers cover nearly every brief. Deposit-side sizing comes from FDIC Bank Data & Statistics. Firm-level profiling of the advice industry runs on SEC Investment Adviser Public Disclosure (IAPD) and the SEC EDGAR Full-Text Search API (EFTS). Cross-country benchmarking uses the World Bank Development Indicators (Financial Sector). Rate-cycle framing comes from the Fed release hub and the Federal Reserve Yield Curve (FEDS) Daily CSV.
How do you size a deposit market by county or CBSA?
A four-step walkthrough covers the standard deliverable:
- Pull the institution universe through the BankFind API - no key is mandatory; registration is described as best practice rather than required.
- Join Summary of Deposits branch rows to institutions on the ID fields, filtering to the June snapshot year your market definitions use.
- Roll branches up to county or CBSA using the supplied geography columns, computing each institution's deposit share per market.
- Add consolidation context from the same platform's 4,115 failure records reaching back to 1934 when the story involves risk or churn.
For field definitions behind each regulatory item - including Call Report and FR Y-9C variables if you extend into bank financials - the Federal Reserve MDRM Data Dictionary publishes 1,332,936 lines of machine-readable item definitions in CSV.
Can public data support cross-country comparisons?
Global expansion chapters need comparable indicators rather than country anecdotes. The World Bank World Development Indicators expose 1,498 indicators across 217 economies through a free API, with 72 tagged to the Financial Sector topic - domestic credit, market capitalization of listed companies, bank capital and reserves among them - running mostly from around 1975 onward under commercial delivery terms 4.0 with attribution. The full WDI bulk CSV ZIP is roughly 10 MB, so a researcher can load everything locally instead of paging an API.
Pair the country table with BIS banking statistics when cross-border claims matter. The BIS Data Portal organizes 26 dataset groups compiled with central banks, with locational banking series back to 1977-Q4 across roughly 45-50 reporting countries; the locational banking bulk CSV alone is about 122 MB compressed and roughly 609,000 rows, shipped free in CSV and SDMX-ML under a mandatory BIS citation. That combination supports liquidity-cycle narratives and counterparty-country exposure maps few commercial packages match on depth.

Then go deeper on the two workflows this page leaned on hardest: FDIC summary of deposits data for branch-level deposit share mechanics, and Form ADV investment adviser database for the advisory-profiling layer.

How do you calculate bank deposit market share by county?
Use FDIC Summary of Deposits, which records deposits for every insured branch each June back to 1994 across 2.8M-plus branch-year rows with county, CBSA and latitude/longitude fields. Sum branch deposits per institution within a county, then divide by total county deposits to produce regulator-sourced share tables.
