After three credit ratings agencies downgraded the commonwealth territory, Puerto Rico municipal bonds have rallied and is now offering $3 billion in bonds. Investors interested in gaining exposure to Puerto Rican debt can take a look at a couple high-yield municipal bond exchange traded funds.

Puerto Rico is offering $3 billion in general-obligation municipal bonds maturing in 2035 with yields between 8.625% to 8.872%, Bloomberg reports.

The S&P Municipal Bond Puerto Rico General Obligation Index has rallied 13.7% year-to-to-date as yields on Puerto Rican debt declined from a record 10.59% on Jan. 2.  Bonds have an inverse relationship to yields, so a falling yield corresponds with rising prices.

David Chafey, chairman of the Government Development Bank, stated that the proceeds will help balance budgets, repay debt and give the island enough time to pay its bills through June 2015.

The commonwealth previously had a low investment-grade rating but was downgraded by Fitch, Moody’s and S&P ratings agencies to speculative-grade, junk status in February due to concerns about its ability to access capital markets. [BlackRock: What Puerto Rico’s Downgrade Means for Investors]
