[Citigroup and Wells Fargo Issue Investment-Grade Bonds Following Fed Rate Hike] Citigroup and Wells Fargo are selling investment-grade bonds after the Federal Reserve raised policy rates for the first time in three years, alleviating concerns over credit risk. Citigroup plans to raise at least $10 billion through a four-part transaction, with bond maturities ranging from 3 to 11 years. Wells Fargo plans to raise at least $5 billion through three batches of bond issuance, with maturities ranging from 4 to 11 years. This financing follows the Fed's 25 basis point rate hike, with the Fed also signaling another rate hike later this year, a move that has helped ease investor concerns about inflation. (Sina Finance)
