FYI:
The biggest providers of exchange-traded funds, which have been funneling billions of investor dollars into some little-traded corners of the bond market, are bolstering bank credit lines for cash to tap in the event of a market meltdown.
Vanguard Group, Guggenheim Investments and First Trust are among U.S. fund companies that have lined up new bank guarantees or expanded ones they already had, recent company filings show.
