Standard & Poor's has cut the Netherlands’ credit to AA+, removing one of the eurozone's few remaining triple-A ratings while rewarding Spain for its efforts to reform public finances with an improved stable outlook.
S&P said the Dutch decision, which leaves Germany, Luxembourg and Finland as the only countries in the currency bloc with the top credit rating, was due to a worsening of growth prospects.
Both Moody's and Fitch still rate the Netherlands as triple A.
"The real GDP per capita trend growth rate is persistently lower than that of peers at similarly high levels of economic development," S&P said in a statement, while affirming the Netherlands' short-term rating at A-1+.
The agency said it had revised its outlook on Spain, which has worked hard over the past two years to reorder its finances, to stable from negative and affirmed its BBB-/A-3 long and short-term foreign and local currency sovereign credit ratings.
It said Spain's external position was improving as economic growth gradually resumes.
"Other credit metrics are stabilizing, in our view, due to budgetary and structural reforms, coupled with supportive euro zone policies," S&P said in a statement.
