BoJ scatters Japan's monetary picture across three government sites: stat-search for the call rate and money stock, MoF for the JGB compound-yield CSV and auction calendar, and the Policy Board statement archive. This actor consolidates all of it into one normalized async pull — interest rates, the 1Y-to-40Y JGB curve, upcoming auctions, monetary base, FX reserves and Policy Board statement PDFs — so a Japan-rates desk replaces three terminal screens with a single structured feed back to 1974.

Built for Japan-rates desks, global macro PMs, JGB arbitrage traders, sovereign-debt analysts, and AI-agent integrations that need clean, structured Japan monetary data without paying $24K/yr for a Bloomberg terminal.


⚡ What you get

Per record (stable 8–12 fields depending on data_type):

dateISO observation date (YYYY-MM-DD)

series_nameHuman-readable English name (e.g. "JGB compound-interest yield, 10Y")
valueNumeric value (rate %, JPY amount, USD millions)
unitUnit string (% per annum, USD millions, 100 million yen, etc.)

accepted_amount_JPYAccepted amount in JPY — null until MoF publishes results
statement_urlDirect PDF link — monetary policy rows only
source_urlSource page on boj.or.jp or mof.go.jp
fetched_atUTC timestamp of the actor fetch

🎯 Use cases

  1. Japan-rates desk — daily JGB curve + BoJ call rate + monetary base in one pull instead of three terminal screens.
  2. Pre-auction calendar feed — MoF publishes ~1 week ahead; size cash-curve trades around 5Y / 10Y / 20Y / 30Y supply.
  3. Sovereign-debt event studies — full historical JGB curve back to 1974/9/24 via date_from=1974-09-24 (the historical CSV).
  4. RAG / AI macro agent — clean structured rows to answer "what did BoJ decide at the April 2026 MPM" with statement-PDF links, or "what's the latest 30Y JGB yield".
  5. Yen-cross desks — pair this actor with the MoF FX-intervention sibling for the rates → reserves → intervention chain.
  6. Research / academia — long-window stable BoJ time series (call rate back to 1998, basic loan rate back to 1882) for monetary-economics papers.

📊 Sample Output

👁 Japan BoJ Macro Rates + JGB Auctions sample

The dashboard renders the latest JGB yield curve (10Y headline), the BoJ basic loan rate (policy rate proxy), the call rate (overnight market rate), upcoming JGB auctions for the month, and recent Policy Board statement PDFs — all in one image with full Japanese terminology rendered in Noto Sans CJK JP.

A single jgb_yields row (data_type=jgb_yields, tenor_filter=10Y):

{
"data_type":"jgb_yields",
"date":"2026-05-29",
"series_code":"JGB_CME_10Y",
"series_name":"JGB compound-interest yield, 10Y",
"value":1.51,
"unit":"% per annum",
"tenor":"10Y",
"source_url":"https://www.mof.go.jp/english/policy/jgbs/reference/interest_rate/jgbcme.csv",
"fetched_at":"2026-05-29T08:00:00+00:00"
}

stop_out_yield / bid_to_cover / accepted_amount_JPY are present only on jgb_auctions rows and are currently null — the actor surfaces the auction calendar, not the post-auction result PDFs.

❓ FAQ

Q: Which is the "policy rate" — basic loan rate or call rate? A: BoJ targets the uncollateralized overnight call rate as its operational policy rate; the basic loan rate (旧公定歩合) is the standing-facility ceiling. Pull data_type: "interest_rates" to get both side-by-side.

Q: Why are auction result fields null? A: Only the auction calendar (date + issue type) is fetched, published up to a week in advance. Auction results (price, yield, B/C ratio, accepted amount) are released ~3 PM JST on the auction day via a separate PDF and are not yet parsed — so stop_out_yield, bid_to_cover and accepted_amount_JPY are null.

Q: How far back does the JGB curve go? A: To 1974 via the historical CSV (date_from=1974-09-24). The actor pulls the current-month CSV for windows ≤30 days and falls back to the 1974~ historical CSV for longer windows.

Q: How current is the data? A: JGB yields are next-trading-day; the call rate updates daily ~2 PM JST; money stock & FX reserves are monthly; Policy Board statements drop immediately post-MPM.

Q: How do I get only the 10Y JGB yield? A: {"data_type": "jgb_yields", "tenor_filter": "10Y"}. The actor filters to a single tenor and pushes one row per trading day.

Q: BoJ vs FRED — should I use this or the FRED actor? A: FRED carries Japan rate series but is US-Treasury-first and lags BoJ's primary feed by hours (sometimes days for monthly releases). FRED also has no JGB auction calendar and no MoF FX reserves. Use this actor for source-of-truth Japan macro.
