A nascent rally in U.S. federal government bonds was upset Wednesday by inflation information that was greater than Wall Street anticipated, marking the most recent twist in a difficult year for bond financiers.
Treasury yields, which increase when bond costs fall, leapt right away after the Labor Department stated that the consumer-price index, leaving out unstable food and energy classifications, climbed up 0.6% in April from the previous month. That was above the 0.4% gain in so-called core costs prepared for by financial experts surveyed by The Wall Street Journal.
