ANBIMA classes

Overview

ANBIMA’s monthly Boletim de Fundos de Investimento — net assets, net flows, returns and fund counts per class (Renda Fixa, Ações, Multimercados, ETF, FIDC, FII, …), per ANBIMA type under each class, and for the industry as a whole. One function serves it long, exactly as published.

These rows are industry aggregates, not funds. No fund in this warehouse is mapped to an ANBIMA class — CVM’s classe is a different taxonomy — so nothing here joins to fund_nav, funds or panel, and a class is never matched to a fund by name. Use them as the benchmark they are.

`anbima_classes`

curl -s -X POST "$SILO_URL/rpc/anbima_classes" \
  -H "apikey: $SILO_ANON_KEY" \
  -H "Content-Type: application/json" \
  -d '{"p_category":"Renda Fixa","p_metric":"pl_brl_mm"}'

Arguments — all optional:

Argument	Default	Meaning
`p_category`	every class	one ANBIMA class, e.g. `Renda Fixa`, `Ações`, `Multimercados`, `ETF` (case-insensitive)
`p_metric`	every metric	one of the boletim metrics below
`p_level`	`category`	`category` (class aggregate) · `type` (the ANBIMA types under a class) · `total` (the industry total) · `null` for every level
`p_from` / `p_to`	2019 → latest edition	window on `reference_date`

An unknown category, metric or level raises 22023 listing what exists rather than returning an empty array — an empty array reads as “ANBIMA published nothing”, a different claim from “you misspelt the class”. One row per (reference date, class, type, level, metric):

[
  { "reference_date": "2026-07-01", "category": "Renda Fixa", "type_id": null,
    "type_name": "Renda Fixa", "level": "category",
    "metric": "pl_brl_mm", "value": 3456789.12, "unit": "brl_mm",
    "boletim_ref": "2026-08", "source": "anbima" }
]

Metrics and units

Values are as published — R$ milhões and percentage points — and unit says which, read off the metric name, never off the number:

`metric`	`unit`	Meaning
`pl_brl_mm`	`brl_mm`	net assets (patrimônio líquido), R$ millions
`captacao_liquida_brl_mm`	`brl_mm`	net flow in the month
`captacao_liquida_ytd_brl_mm`	`brl_mm`	net flow, year to date
`captacao_liquida_12m_brl_mm`	`brl_mm`	net flow, trailing 12 months
`rentabilidade_pct`	`pct`	return in the month, percentage points (`4.37` = 4.37 %)
`rentabilidade_ytd_pct`	`pct`	return, year to date
`rentabilidade_12m_pct`	`pct`	return, trailing 12 months
`fund_count`	`count`	number of funds

Class-level pl_brl_mm, captacao_liquida_brl_mm and fund_count carry the full published history (from 2006); the type-level and return series cover the trailing window each boletim edition prints (about 19 months). A longer type-level window returns what was published, not a reconstruction.

Why `level` is part of the grain

Cambial, FIP and FIAGRO each appear twice in the same boletim sheet — once as the class aggregate, once as an ANBIMA type of the identical name. level keeps them apart:

# both rows for FIP, side by side
-d '{"p_category":"FIP","p_level":null}'

Note: one 1,000-row page, and it refuses above it (22023). No cursor — narrow the window, or pin a p_category or p_metric.

Freshness

coverage carries an anbima_classes row whose complete_through equals its as_of: a published edition is complete by construction, so there is no partial trailing month to clamp.
