How Often Is Your Data Refreshed?

Q: How often is your swap rate, forward curve, FX, and government bond data updated?

Swap rate and forward curve update frequency depends on the specific index. Each rate falls into one of the following buckets:

• Every ~30 seconds, 24/7 — SOFR, Fed Funds, AONIA, 3M BBSW, 6M BBSW, 3M BBSY, 6M BBSY, TONAR, 3M TIBOR, 6M TIBOR, 91D CD.

• Every ~30 seconds, market hours — SONIA, ESTR, SARON, CORRA, POLONIA, 1M/3M/6M EURIBOR, CIBOR, NIBOR, 3M STIBOR, 3M JIBAR, HIBOR, SORA, and other benchmarks that trade during local market hours.

• Several times a day, market hours — EIBOR (AED), 28 Day TIIE, 3M KLIBOR, 7D REPO, Overnight MIBOR, 6M WIBOR, 3M BKBM, CDI.

• Once daily at 2pm London — most app-only indices, including 1M BBSW, 12M EURIBOR, 6M HIBOR, 3M WIBOR, 6M STIBOR, and overnight risk-free rates such as HONIA, ZARONIA, SWESTR, NZONIA.

For the bucket each index falls into, see Available Indices.

Other data:

• FX rates:

  • Real-time streaming (via SSE): live updates as new prices arrive.

  • Non-streaming: refreshed once per minute.

• Government bonds: updated once daily, reflecting the latest end-of-day market levels.

• API & Excel Add-in: pull from the same data source as the app — update frequency matches what's above.

Why the update frequency varies

• Market liquidity: continuously traded benchmarks like SOFR or BBSW generate enough two-way flow to produce near-live quotes. Less liquid markets produce fewer quotes per day.

• Daily fix coverage: for some rates BlueGamma publishes the once-daily fix rather than intraday quotes. This covers 1M BBSW, 12M EURIBOR, 6M HIBOR, and certain smaller-market overnight risk-free rates (HONIA, ZARONIA, NZONIA, SWESTR, etc.). Major RFRs like SOFR, SONIA, ESTR, SARON, TONAR, AONIA, and CORRA update live — see the buckets above or app-only indices for the full list.

• Quote availability: for thinner markets we only refresh when new quotes are published, so you see genuine price changes rather than repeats of stale data.

Data type	Update behaviour
Swap rates & forward curves — continuously traded benchmarks	Every ~30 seconds, 24/7
Swap rates & forward curves — session-traded benchmarks	Every ~30 seconds, market hours
Swap rates & forward curves — less liquid benchmarks	Several times a day, market hours
Swap rates & forward curves — daily fixings	Once daily at 2pm London
FX rates (streaming)	Real-time (via SSE)
FX rates (non-streaming)	Every 1 minute
Government bonds	Once daily (end-of-day)
API & Excel Add-in	Same as the web app

In summary Expect ~30-second refreshes for major currency swap data, real-time FX streaming, and a once-daily 2pm London fix for daily-fixing benchmarks.
