parsimony-riksbank

Sveriges Riksbank (Sweden's central bank) connector plugin for parsimony. Surfaces all five of the Riksbank's public REST APIs: interest & exchange rates (SWEA), the Swedish Krona Short-Term Rate (SWESTR), Monetary Policy forecasts & outcomes, market Turnover Statistics, and securities Holdings. Keyless — no API credentials required.

Part of the parsimony-connectors monorepo. Distributed standalone on PyPI as parsimony-riksbank.

Connectors

Install

pip install parsimony-riksbank

Pulls in a compatible parsimony automatically. Verify discovery:

python -c "from parsimony import discover; print([p.name for p in discover.iter_providers()])"

Quick start

from parsimony_riksbank import CONNECTORS

# The Riksbank's GDP forecast (annual % change), latest policy round.
result = CONNECTORS["riksbank_monetary_policy_fetch"](
    series="SEQGDPNAYSA",
    policy_round="2026:1",
)
print(result.raw.head())

Catalogs

This plugin ships a riksbank catalog (~156 entries) driven by enumerate_riksbank. riksbank_search loads a published snapshot (overridable via the PARSIMONY_RIKSBANK_CATALOG_URL env var) and falls back to building one in-process when no snapshot is reachable. Maintainers build and push the snapshot with scripts/build_catalog.py.

The catalog code routes the follow-up fetch:

• bare SWEA id (e.g. SEKEURPMI) → riksbank_fetch(series_id=...)
• bare SWESTR id (e.g. SWESTR, SWESTRAVG1M) → riksbank_swestr_fetch(series=...)
• monetary_policy/<id> → riksbank_monetary_policy_fetch(series=<id>)
• turnover/<market>/<frequency> → riksbank_turnover_fetch(market=, frequency=)
• holdings/<dataset> → riksbank_holdings_fetch(dataset=<dataset>)

Coverage

The Riksbank publishes five public REST APIs (confirmed against the developer portal's API list); this plugin covers all five.

Catalog covers ALL: yes for the series-shaped products — SWEA /Series and Monetary Policy /forecasts/series_ids are authoritative live enumerations, and SWESTR / Turnover / Holdings have small, stable dimensions enumerated as registries. Connectors cover ALL accessible data: yes — every product has a fetch verb. Notes on deliberate scope:

• SWESTR PRESWESTR (preliminary 2021 test-period values) is excluded as superseded test data.
• SWEA derived endpoints — CrossRates, ObservationAggregates, CalendarDays — are computed conveniences over the same 117 series (cross-rate calculation, resampling, banking-day lookups), not new addressable series, so they are not catalogued.
• Turnover is catalogued at the (market, frequency) dataset granularity; the asset/contract/counterparty facets are returned inside each dataset. The Excel-report endpoints duplicate the JSON content and are not wrapped.

Authentication & rate limits

All five products are open / keyless. An optional Ocp-Apim-Subscription-Key (set RIKSBANK_API_KEY or pass api_key=) only raises the keyless quota of 5 requests/minute, 1000/day per IP — recommended for full catalog builds.
