Rates held steady Tuesday morning as positive economic news helped offset a large drop in BP shares. The Institute for Supply Management manufacturing index reading fell to 59.7, a bit less than expected. Readings above 50.0 indicate expansion in the manufacturing sector of the economy, which has now grown for 10 consecutive months. Construction Spending surged 2.7%. An increase of 0.1% had been forecast. No other data will be released today.
