Developed Markets Sovereign Rating Model

 | May 14, 2015 12:23AM ET

We have produced this ratings model to assist investors in assessing relative sovereign risk over a wide range of Developed Markets (DM), 29 in all. Scores directly reflect a country’s creditworthiness and its underlying ability to service sovereign debt obligations.

Each country’s score is determined through a weighted compilation of fifteen economic and political indicators, which include debt/GDP, current account/GDP, GDP growth, actual and structural budget balance, per capita GDP, banking sector strength, and inflation. These scores translate into a BBH implied rating that is meant to reflect the accepted rating methodology used by the major agencies.
h3 DEVELOPED MARKETS RATINGS SUMMARY/h3


There were 12 DM rating actions that have been recorded this year. In a sign that some cracks in DM are reappearing, 4 were positive and 8 negative. Last quarter (Q4), there were 10 actions (5 positive, 5 negative). This year, however, Greece accounted for 6 of the 8 negative actions. Netting Greece out gives a more positive view on DM ratings.

With regard to Greece, S&P first put it on negative watch in January and then downgraded it twice, first from B to B- and then again to CCC+ with a negative outlook. Moody’s put Greece on review for downgrade in February and then cut it from Caa1 to Caa2 with a negative outlook. Lastly, Fitch downgraded Greece from B to CCC in March. The other 2 negative actions were both by Fitch. It downgraded Austria from AAA to AA+ with a stable outlook, and downgraded Japan from A+ to A with a stable outlook.

On the positive side, Moody’s was the most upbeat with three actions. It upgraded Slovenia from Ba1 to Baa3 with a stable outlook, upgraded Latvia from Baa1 to A3 with a stable outlook, and upgraded Lithuania from Baa1 to A3 with a stable outlook. S&P provided the sole move for Portugal, raising the outlook on its BB rating from stable to positive.
