Spanish bond yields rose higher on Thursday after investors continued to worry about the European nation's ability to meet its budget projections.
The spiking Spanish 10-year bond yields, which reached 5.84 percent, are likely continue in the near term, a phenomenon that has increased worries about the ability for some eurozone countries to meet debt obligations.
Bond yields and prices of bonds are inversely related.
Spanish yields reached their highest levels since the European Central Bank made the first of two loan injections that will act as a bulwark against a eurozone credit crunch by adding needed liquidity, reported the Financial Times.
There is now fear that the Central Bank's actions may be fading after giving a boost to the region's economies earlier in the year.
