NRI income as Gift to wife

My status was NRI from 2007 to 2014. My wife was also NRI. While abroad we kept our money clubbed. Due to visa issue she had to come back to India in 2013 and i also returned back in 2014. My status was RNOR for next two years.
Now i have job in India and wife is homemaker. All our NRI income is in FD in her name now (since part of it is her NRI income and part of mine NRI income). My question is : giving NRI savings as gift to wife, can income tax department consider it as clubbing of income? All this amount was earned outside India as NRI. (she is now paying Tax on interest earned through FDs)
