The guessing game on when the Fed will raise rates is in full force as Wall Street eyes the release of the Fed minutes from its March meeting when the word 'patient' was removed from the statement. Brian Rehling is the co-Head of Global Fixed Income Strategy at Wells Fargo Investment Institute (WFC) and says despite the weak jobs report, he thinks a hike is still coming in September. Rehling says 'it's not because the Fed needs to raise rates but they want to get started this year.' As for the world's largest fixed-income portfolio, Rehling doesn't see the Fed unwinding in 2016 while raising rates saying 'I think we'll see them continuing to reinvest.'
