4. -- The Social Security Administration is warning that it can't guarantee full benefit payments if the debt ceiling isn't increased, The Wall Street Journal reported. When asked by the public, the agency is notifying beneficiaries that "unlike a federal shutdown which has no impact on the payment of Social Security benefits, failure to raise the debt ceiling puts Social Security benefits at risk," according to a person familiar with the agency directive, the Journal reported. The agency's warning comes after it consulted with the Treasury Department, which would play a lead role in determining how the government handles payments if the borrowing limit isn't raised soon, the Journal said. "Our employees started receiving questions from the public, so the agency worked with Treasury to provide an answer they could use when asked about the debt ceiling by the public," a Social Security Administration spokesman said. The current $16.7 trillion debt ceiling will be hit on Oct. 17.
