# 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](/documentation/integrations/available-indices.md#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](/documentation/integrations/available-indices.md).

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](/documentation/integrations/available-indices.md#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.
