U.K. Blunders May Permanently Scar Gilts, JPMorgan Analyst Says

Intermediate U.K. yields will likely price “increased risk premia on a cross-market basis going forward,” said Francis Diamond.

The gilt market chaos triggered by the government’s fiscal statement last month may have lasting consequences for UK borrowing costs, according to JPMorgan Chase & Co. rates strategist Francis Diamond.

“The disruptive delivery” of the update by Chancellor of the Exchequer Kwasi Kwarteng on Sept. 23, “combined with still lingering uncertainty” around the details and long-term sustainability of his plans “will leave a more permanent scar on GBP rate markets,” Diamond wrote in a note on Monday. 

Intermediate UK yields will likely price “increased risk premia on a cross-market basis going forward,” he added.

The call came amid a severe selloff that saw some UK inflation-linked yields surge by the most on record. The Bank of England expanded the scope of its bond purchases on Tuesday to include inflation-linked debt in an effort to avert what it called a “fire sale.”

Yields may continue to rise -- albeit in a more orderly manner -- even though “peak fiscal uncertainty has likely passed,” after the government u-turned in several areas and brought forward its fiscal assessment, Diamond wrote. 

Long-dated and inflation-linked bonds were particularly affected by collateral calls favored by defined-benefit pension programs.

Once liability-driven investment “asset managers have delevered and raised cash we would expect demand for long gilt and linkers to materialize,” Diamond wrote. “But this may be several months away.”
