This is from Jim Hamilton's Econbrowser blog. More details about this new indicator.
Most recently, researchers have tried to gauge the degree of financial stress using indicators such as the LIBOR-OIS spread ([1], [2]) or deviations of yields from predictions of interest rate models (e.g., the recent paper by Christensen, Lopez, and Rudebusch). There are also a number of composite indexes that various private-sector analysts rely on, such as the Bloomberg financial conditions index.
Two private-sector analysts (Jan Hatzius of Goldman Sachs and Peter Hooper of Deutsche Bank) have recently teamed up with three academics (Rick Mishkin of Columbia, Kermit Schoenholtz of NYU, and Mark Watson of Princeton) to produce a new financial conditions index that attempts to combine the information of 44 separate series including those mentioned above along with a great number of others. One of the differences between their approach and previous work is that HHMSW seek to isolate the separate information of the financial indicators from aggregate business cycle movements by looking at the residuals from a regression of each indicator on lags of inflation and real GDP growth rates.
