Placement Ratio: A Key Indicator of Municipal Bond Market Strength

3 Min.

The placement ratio, also known as the acceptance ratio, measures the percentage of new municipal bond offerings exceeding $1 million purchased in the previous week. A higher placement ratio signifies a robust municipal bond market, while a lower ratio indicates a sluggish market. This indicator is critical for gauging the market's overall health and predicting its future direction.


The placement ratio, often referred to as the acceptance ratio, plays a vital role in assessing the strength and vitality of the municipal bond market. This ratio provides valuable insights into the market's dynamics by comparing the number and value of newly issued municipal bonds during a specific week to the number and value of bonds actually sold during that same period. In essence, it represents the dollar amount of new bonds that underwriters have successfully placed with investors, expressed as a percentage of the previous week's new municipal bond offerings. The formula for calculating the placement ratio is relatively straightforward:

Placement Ratio = Municipal Bonds Sold / Municipal Bonds Available

This formula divides the value of municipal bonds sold by the total value of municipal bonds available, resulting in a percentage that indicates how well the market absorbed the bonds offered in the preceding week.

Interpreting the Placement Ratio

The placement ratio is not just a random statistic; it carries significant implications for market participants. The key takeaways are as follows:

  1. Market Strength: The higher the placement ratio, the stronger the overall municipal bond market. A high placement ratio suggests that bond underwriters are finding eager investors. It indicates robust demand for municipal bonds and favorable conditions for issuers.
  2. Market Weakness: Conversely, a low placement ratio signals a market that is struggling. It indicates a lack of interest from bond underwriters and slower bond absorption by investors. In this scenario, the market is less favorable for issuers.

Example Calculation

To better understand how the placement ratio works, consider an example:

Suppose that last week, $100 million worth of municipal bonds were issued. Out of this, underwriting syndicates managed to sell $70 million. The placement ratio can be calculated as follows:

Placement Ratio = ($70 million / $100 million) x 100% = 70%

This 70% placement ratio demonstrates how effectively the market absorbed the bonds offered during the previous week.

The Bond Buyer and the Placement Ratio

The data needed to calculate the placement ratio is systematically compiled and published on a weekly basis by a renowned financial publication, The Bond Buyer. This publication specializes in covering the municipal bond market and provides market participants with essential information.

One of the noteworthy indices published by The Bond Buyer is the Bond Buyer 20 Index. This index closely monitors the average yields of 20 general obligation municipal bonds, which are typically rated Aa2 by Moody's or AA by Standard & Poor's. The data collected by this index is pivotal in determining the interest rates for new issues of general obligation bonds.

The Bond Buyer's placement ratio is compiled every week and made available on Mondays, based on data gathered at the close of business the preceding Friday. Market participants can access the publication's archive to examine placement ratios from past weeks and identify any long-term trends, thus providing a comprehensive view of the market's historical performance.


In the intricate world of municipal bonds, the placement ratio serves as a compass, guiding investors, issuers, and underwriters. By examining the ratio, market participants gain insights into the market's current health and its future prospects. A high placement ratio signifies a strong market with robust investor interest, while a low ratio indicates a more challenging environment. Understanding this essential metric is crucial for making informed decisions and navigating the municipal bond market successfully.
