Rates were little changed Thursday in volatile trading. This morning, the European Central Bank (ECB) announced it would increase its asset purchase program to 80 billion euros each month from 60 billion and lowered all key interest rates in an effort to boost economic growth. The ECB cut its main interest rate, the rate it charges on regular bank loans, to zero percent, an all-time low. Global stock markets rallied on the news. In the U.S., weekly Jobless Claims fell to 259,000, well below the consensus forecast of 275,000. Results from today’s 30-year Treasury auction will be released at 1:00 PM.
