A US default
on its obligations forced by Congress not raising the country's borrowing
ceiling would have catastrophic effects, the Treasury warned Thursday.
With the
government likely to exhaust its cash reserves around October 17, the Treasury
said being forced into non-payment of any of its obligations -- and in
particular its debt -- would spark turmoil in financial markets and possibly
send the country back to a recession as deep as that of 2008-2009.
