Understanding S&P corelogic case-shiller home price indices
Composition and methodology
The S&P CoreLogic Case-Shiller Home Price Indices are based on a comprehensive dataset of single-family properties that have undergone at least two arm’s length transactions. This ensures a reliable measure of housing price changes, as transactions between unrelated parties reflect true market dynamics. The indices cover various geographic areas, including national, metropolitan statistical areas (MSAs), and individual cities.
The group of indices includes:

Covering ten major cities, this composite index provides a more localized view of home price changes. Cities included in this index are Boston, Chicago, Denver, Las Vegas, Los Angeles, Miami, New York, San Diego, San Francisco, and Washington, D.C.
S&P coreLogic case-shiller 20-city composite home price NSA index

Pros and cons
Impact on financial markets
The S&P CoreLogic Case-Shiller Home Price Indices not only provide valuable insights into the real estate market but also have a significant impact on financial markets. Investors closely monitor these indices as they reflect broader economic trends and consumer confidence. For example, a sustained increase in home prices may indicate a robust economy and lead to higher consumer spending. Conversely, a decline in home prices could signal economic weakness and prompt investors to adjust their investment strategies accordingly.
Example: Market volatility
During periods of market volatility, such as economic downturns or geopolitical uncertainty, the S&P CoreLogic Case-Shiller Home Price Indices can serve as a barometer of investor sentiment. For instance, a sharp decline in home prices across multiple metropolitan areas may trigger selling pressure in the stock market as investors become concerned about the health of the economy. Conversely, a rebound in home prices could boost investor confidence and lead to increased market activity.
Example: Mortgage-backed securities
Mortgage-backed securities (MBS) are financial instruments that represent ownership interests in pools of mortgage loans. The performance of MBS is closely tied to the housing market, making the S&P CoreLogic Case-Shiller Home Price Indices a crucial factor in assessing their value. For instance, a decline in home prices may increase the risk of default on mortgage loans, leading to lower returns for MBS investors. Conversely, rising home prices can enhance the creditworthiness of mortgage loans and increase the value of MBS.
Implications for policy
The S&P CoreLogic Case-Shiller Home Price Indices also have implications for policymakers at the local, state, and federal levels. Changes in home prices can affect various aspects of the economy, including consumer spending, employment, and tax revenues. Policymakers often use data from these indices to inform decisions related to housing policy, economic development, and fiscal planning.
Example: Housing affordability
One of the key challenges facing policymakers is ensuring housing affordability for residents, particularly in high-cost metropolitan areas. The S&P CoreLogic Case-Shiller Home Price Indices provide valuable data on home price trends, allowing policymakers to assess affordability levels and identify areas where intervention may be necessary. For example, if home prices are rising rapidly relative to income growth, policymakers may consider implementing measures to increase housing supply or provide financial assistance to homebuyers.
Example: Financial regulation
The housing market plays a significant role in the stability of the financial system, as evidenced by the 2008 financial crisis. Regulators closely monitor developments in the housing market, including changes in home prices, mortgage lending practices, and foreclosure rates. The S&P CoreLogic Case-Shiller Home Price Indices serve as an important tool for assessing systemic risks and informing regulatory decisions. For instance, if home prices are experiencing excessive volatility or speculative activity, regulators may take steps to mitigate potential risks to financial stability.
