# Bankstatemently Open Benchmark

A standardized benchmark for evaluating bank and credit card statement PDF parsers. 15 synthetic statements across 3 difficulty tiers, 12 countries, 8 languages, and 41 parsing challenges.

**5 of 15 statements are released here** (PDFs + metadata); the rest are coming soon — see the [full dataset on GitHub](https://github.com/bankstatemently/bank-statement-parsing-benchmark) for status, or [browse it on the website](https://bankstatemently.com/benchmark).

## Design: ground truth is never in this dataset

This repo ships PDFs and structural metadata only — no transaction-level answers. Ground truth stays server-side so parsers cannot overfit to the answers. Score your parser's output via Bankstatemently's free evaluation API: [https://bankstatemently.com/developers/api](https://bankstatemently.com/developers/api).

## Dataset changelog

Statements are occasionally reissued to fix errors. A parse or score produced against a superseded PDF is not comparable to results against the current one. Check here before comparing results across dates.

### 2026-08-07: bsb-004, Silk Road Banking (Hong Kong)

Reissued to correct errors in the original statement. The second account is now denominated in USD, with a disclosed FX rate.

- Superseded by: `522f8c9c92cb567580ffca4ac5ff9d4caea7d831764671de0ab8ae0878e513c2`
- Parses or scores produced against the original PDF are not comparable. Re-parse the reissued PDF.
