NEW YORK (CNN/Money) - The U.S. dollar pushed to two-month highs against the euro on Thursday in a broad rally fired by positive sentiment and persistent speculation about a big investor buying dollars.

In late New York trading, the euro bought $1.2824, down from $1.2910 late Wednesday, while the dollar bought ¥108.08, up from ¥107.41 on Wednesday.

In the Treasury market, prices traded mixed as bond traders favored shorter-dated maturities.

The benchmark 10-year note added 2/32 of a point to 97-4/32, yielding 4.36 percent, unchanged from the previous session. The 30-year bond fell 14/32 of a point to 109-25/32 to yield 4.72 percent, up from 4.69 percent Wednesday. Bond prices and yields move in opposite directions.

The short-end was faring better, with two-year notes climbing 3/32 to 100-9/32 for a yield of 3.60 percent, down from 3.66 percent. The five-year note rose 5/32 of a point to 100-1/32 to yield 3.99 percent.

In an auction Thursday of $9 billion Treasury inflation-protected securities, or TIPS, the bonds sold at a high yield of 1.750 percent. It drew bids for 1.97 times the amount of debt on offer, close to the historical average for this type of debt.

Indirect bidders, including customers of primary dealers and foreign central banks, picked up $3.78 billion, or 42 percent, of the issue, up from 38 percent at the last TIPS sale. Primary dealers themselves got $5.08 billion of the issue.

The current 10-year TIPS was yielding 1.72 percent.

Recent worries about rising inflation have been pushed aside for now, giving way to concerns about the outlook for consumer spending, the growth engine of the U.S. economy.

Several economists lowered estimates for first-quarter growth this week after weak March retail sales and a record February trade deficit.

A report on business inventories published on Thursday suggested companies are still ratcheting up their stocks of goods to meet demand, a positive for GDP growth.

"Inventory building is slightly stronger in January and February than it was in 4Q, suggesting that inventory investment is likely to add modestly to Q1 GDP growth," Steven Wood, chief economist at Insight Economics, told Reuters.

Business inventories rose 0.5 percent in February, in line with what economists had been looking for, from an increase of 0.9 percent in January.

Meanwhile, the number of U.S. jobless claims fell to 330,000 in the week ended April 9, in line with economists' expectations, from a revised 340,000 in the week previous.
