The US Treasury 1-Month rate, represented by the symbol US_TREASURY_1M, is a critical benchmark for financial markets, influencing various aspects of risk management and trading strategies. Its volatility can significantly impact investment decisions, borrowing costs, and overall economic conditions. In this blog post, we will delve into the analysis of the US Treasury 1-Month rate's fluctuations, utilizing the Interest Rates API to extract and analyze relevant data.
Understanding the volatility of this rate is essential for developers building fintech applications, economists, quantitative analysts, and financial data engineers. By leveraging the capabilities of the Interest Rates API, we can gain insights into historical trends, current rates, and predictive analytics that can inform strategic decisions.
Measuring Rate Fluctuations
To analyze the fluctuations of the US Treasury 1-Month rate, we can utilize the /fluctuation endpoint of the Interest Rates API. This endpoint provides change statistics over a specified date range, including the start and end values, percentage change, and the highest and lowest rates during that period.
Here’s how to make a request to the fluctuation endpoint:
curl "https://interestratesapi.com/api/v1/fluctuation?start=2025-07-12&end=2026-07-12&symbols=US_TREASURY_1M&api_key=YOUR_KEY"
The expected JSON response will look like this:
{
"success": true,
"rates": {
"US_TREASURY_1M": {
"start_date": "2025-07-12",
"end_date": "2026-07-12",
"start_value": 5.50,
"end_value": 5.33,
"change": -0.17,
"change_pct": -3.09,
"high": 5.50,
"low": 5.25
}
}
}
In this response, we can see that the US Treasury 1-Month rate started at 5.50% and ended at 5.33%, indicating a decrease of 0.17% over the specified period. The percentage change of -3.09% reflects the rate's volatility, while the high and low values provide context for its range during this timeframe.
Monthly Candlestick Patterns with OHLC Data
To further analyze the US Treasury 1-Month rate, we can utilize the /ohlc endpoint to retrieve Open, High, Low, and Close (OHLC) data. This data is essential for visualizing trends and making informed trading decisions.
Here’s how to request OHLC data for the US Treasury 1-Month rate:
curl "https://interestratesapi.com/api/v1/ohlc?symbols=US_TREASURY_1M&period=monthly&start=2025-07-12&end=2026-07-12&api_key=YOUR_KEY"
The expected JSON response will look like this:
{
"success": true,
"period": "monthly",
"start_date": "2025-07-12",
"end_date": "2026-07-12",
"rates": {
"US_TREASURY_1M": [
{
"period": "2025-01",
"open": 5.50,
"high": 5.50,
"low": 5.33,
"close": 5.33,
"data_points": 23
}
]
}
}
In this response, the OHLC data for January 2025 shows that the rate opened at 5.50%, reached a high of 5.50%, and a low of 5.33%, closing at 5.33%. This data is crucial for traders who rely on candlestick patterns to make decisions based on market sentiment and price action.
Time Series Analysis of Rate Movements
To visualize the movements of the US Treasury 1-Month rate over time, we can use the /timeseries endpoint. This endpoint allows us to retrieve daily rates between two specified dates, enabling us to plot the rate movements and calculate rolling volatility.
Here’s how to request time series data:
curl "https://interestratesapi.com/api/v1/timeseries?start=2025-07-12&end=2026-07-12&symbols=US_TREASURY_1M&api_key=YOUR_KEY"
The expected JSON response will look like this:
{
"success": true,
"base": "USD",
"start_date": "2025-07-12",
"end_date": "2026-07-12",
"rates": {
"US_TREASURY_1M": {
"2025-01-02": 5.33,
"2025-01-03": 5.33,
"2025-01-06": 5.33
}
},
"frequencies": {
"US_TREASURY_1M": "daily"
},
"currencies": {
"US_TREASURY_1M": "USD"
}
}
With this data, we can utilize Python and the Pandas library to calculate rolling volatility. Here’s a sample code snippet:
import requests
import pandas as pd
response = requests.get(
'https://interestratesapi.com/api/v1/timeseries',
params=dict(start='2025-07-12', end='2026-07-12', symbols='US_TREASURY_1M', api_key='YOUR_KEY')
)
data = response.json()
rates = data['rates']['US_TREASURY_1M']
df = pd.DataFrame.from_dict(rates, orient='index', columns=['Rate'])
df.index = pd.to_datetime(df.index)
# Calculate rolling volatility
df['Rolling Volatility'] = df['Rate'].rolling(window=30).std()
print(df)
This code retrieves the time series data, converts it into a DataFrame, and calculates the rolling standard deviation over a 30-day window, providing insights into the rate's volatility over time.
Practical Applications of Rate Data
The data obtained from the Interest Rates API can be utilized in various practical applications, including:
