Fed Funds Rate.

Get Effective Federal Funds Rate data. A bank rate is the interest rate a nation's central bank charges to its

United States, the Federal Reserve System's Board of Governors set the bank rate, also known as the discount rate.

```python wordwrap
obb.fixedincome.rate.effr(start_date: Union[date, str] = None, end_date: Union[date, str] = None, provider: Literal[str] = fred)
