Bankstatemently/bank-statement-parsing-benchmark

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 for status, or browse it on the website.

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.

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 A parse or score produced against a superseded PDF is not comparable to results against the current one.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.

2026-08-11: bsb-001, Straits Capital (Singapore)

Reissued to fix a benchmark-generator reproducibility bug (non-deterministic PDF metadata: creation date, embedded font-subset tags, image object ordering). Printed content and every ground-truth answer are unchanged.

• Original PDF sha256: 7f96da7316b2b540f2f8ecfc4151cd242a501be3ed84204a15bfbbe3c355531b
• Superseded by: 8a5b0e296d5d9ffaccfe6e8d99e0b52f7f60db76db54132c8c9ce6b8cbd52720
• Parses or scores produced against the original PDF remain valid (content is unchanged) but were keyed to a superseded hash — re-key to the current hash rather than re-parsing.

2026-08-11: bsb-002, Liberty National (United States)

Reissued to fix a benchmark-generator reproducibility bug (non-deterministic PDF metadata: creation date, embedded font-subset tags, image object ordering). Printed content and every ground-truth answer are unchanged.

• Original PDF sha256: f9947911a399ff0ccb7e8afde6e3380e3f7a1f61a5809b68022ce0b9ba449b06
• Superseded by: 7632b2a50b3ab172e18f03ea110241660c220a4ef738bbfb683eba4cccbbc324
• Parses or scores produced against the original PDF remain valid (content is unchanged) but were keyed to a superseded hash — re-key to the current hash rather than re-parsing.

2026-08-11: bsb-003, Continental Trust (Netherlands)

Reissued to fix a benchmark-generator reproducibility bug (non-deterministic PDF metadata: creation date, embedded font-subset tags, image object ordering). Printed content and every ground-truth answer are unchanged.

• Original PDF sha256: d605ff5e2c803f531c18d295354f135017c56082538f41e53d6c37452604a566

• Parses or scores produced against the original PDF remain valid (content is unchanged) but were keyed to a superseded hash — re-key to the current hash rather than re-parsing.

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.

• Original PDF sha256: e93cacdb23195adefdf13ef4ba9528f55454c6fb2dc83624fe9c5077c5bc6455
• Superseded by: 522f8c9c92cb567580ffca4ac5ff9d4caea7d831764671de0ab8ae0878e513c2
• Parses or scores produced against the original PDF are not comparable. Re-parse the reissued PDF.

2026-08-11: bsb-004, Silk Road Banking (Hong Kong)

Reissued to fix the same generator reproducibility bug as the other released statements, plus a generator fix to how ground-truth account identity is derived: the account name no longer bakes in the account number, which lets a parser that correctly componentizes the printed heading exact-match cross-engine. Printed content (including the heading) is unchanged.

• Original PDF sha256: 522f8c9c92cb567580ffca4ac5ff9d4caea7d831764671de0ab8ae0878e513c2
• Superseded by: 0a4201b0e1a9c9ed834a2dce898a97ef8bac2b959ae6e3eb041c59328e0b19d1
• Parses or scores produced against the previous PDF remain valid (printed content is unchanged) but were keyed to a superseded hash — re-key to the current hash rather than re-parsing.

2026-08-11: bsb-005, Harbour Bank (Canada)

Reissued to fix a benchmark-generator reproducibility bug (non-deterministic PDF metadata: creation date, embedded font-subset tags, image object ordering). Printed content and every ground-truth answer are unchanged.

• Original PDF sha256: 01a26c767b9488e45b358b329e2c9ea3d9fba05878a1963da06fde899827debb

2026-08-14: bsb-001, Straits Capital (Singapore)

Reissued to fix account numbers that were previously a static, non-random digit string shared by every synthetic statement for that banking tag. Account numbers now come from a country-keyed format table (#4931).

• Original PDF sha256: 8a5b0e296d5d9ffaccfe6e8d99e0b52f7f60db76db54132c8c9ce6b8cbd52720

• Parses or scores produced against the previous PDF are not comparable — the printed account number changed, which changes account identity and every dependent ground-truth value. Re-parse the reissued PDF.

2026-08-14: bsb-003, Continental Trust (Netherlands)

Reissued to fix the account number: NL is an IBAN country, but the old template randomized a two-letter "country code" instead of emitting NL's literal IBAN prefix, and the checksum was never a valid ISO 7064 mod-97-10 IBAN check digit. Account numbers now come from a country-keyed format table that emits a real, check-digit-valid IBAN for NL (#4931).

• Original PDF sha256: 4bad73296bdbcf7142b62c8af421527f88d1d3a6865617e9fea48e6f51c704a1

2026-08-14: bsb-004, Silk Road Banking (Hong Kong)

Reissued to fix account numbers that were previously a static, non-random digit string shared by every synthetic statement for that banking tag. Hong Kong has no single documented national account-number scheme, so the new generic digit format is honestly noted as such rather than citing a fabricated standard. Account numbers now come from a country-keyed format table (#4931).

• Original PDF sha256: 0a4201b0e1a9c9ed834a2dce898a97ef8bac2b959ae6e3eb041c59328e0b19d1

2026-08-14: bsb-005, Harbour Bank (Canada)

Reissued to fix the account number: Canada has no IBAN, but the old template printed a French IBAN (inherited from the base fr.json dictionary — format was keyed by language, not jurisdiction). Account numbers are now keyed by country, so fr-CA prints Canada's 5-digit-transit + 3-digit-institution + 7-digit-account format instead of France's IBAN (#4931).

• Original PDF sha256: 8919aa5abdb06d377898e5cc78751661fcc80a25a89a477af49ceb0f0d7fe143
