LONDON, Jan 20 (Reuters) - Thirty-year benchmark British government bond yields were on course for their biggest daily jump since the run-up to finance minister Rachel Reeves's budget in November as U.S. President Donald Trump intensified his pursuit of Greenland.
Thirty-year gilt yields GB30YT=RR rose by nearly 9 basis points on the day to 5.254% at 1035 GMT on Tuesday, their highest level since January 6 and in line with rises in equivalent U.S. bonds US30YT=RR.
The increase on the day was the biggest since November 14 when British financial markets were hit by speculation about Reeves' November 26 annual tax and spending plan announcement.
U.S. Treasury yields hit a four-month high after Trump threatened to reignite a trade war with Europe as part of his push to take control of Greenland.
Ten-year gilt yields GB10YT=RR also rose, up 7 bps on the day at 4.493%, while five-year gilt yields GB5YT=RR, which are more sensitive to interest rate expectations, were 4 bps higher.
The Bank of England is expected to hold interest rates at 3.75% in February, and investors were pricing in one or two 0.25 percentage-point interest rate cuts by the end of 2026, according to LSEG data.
