Bond yields climbed on Tuesday to their highest in decades, with oil prices rising for a third day, while stocks gave up early gains in Asian trade as a U.S.-Iran truce expired and Tehran threatened to adopt a "fully offensive" military posture.
The yield on the U.S. 30-year Treasury bond rose as much as 1.1 basis points to an intraday high of 5.321%, its highest in almost 20 years. Its 10-year counterpart traded up 0.4 basis point at 4.724%.
"Typically, moves above 4.65% for the U.S. 10-year have been followed by some soothing words from the Trump administration, typically centred on an imminent resolution to the war with Iran," ING analysts wrote in a note.
"This time, we're not hearing the same," they added. "In fact, the latest indications are for no imminent resolution as the shaky 60-day truce came to an end."

Overnight on Wall Street, the S&P 500 (.SPX) slipped 0.5% while the Nasdaq Composite (.IXIC) edged 0.3% lower as soft U.S. economic data, including an unexpected drop in retail sales, led traders to reduce bets on an imminent Fed interest rate move.
