UK Gilt Yields Near 30-Year Highs As Political/Geopolitical Fears Spark Trussian Chaos

UK Gilt Yields Near 30-Year Highs As Political/Geopolitical Fears Spark Trussian Chaos Anyone has been in the bond markets for more than a minute remembers the fall of 2022 when UK PM Liz Truss was unceremoniously dumped by her own party after serving 45 days in office as the Gilts market collapsed at unprecedented speed amid economic chaos triggered by her 'mini-budget' (and multiple ministerial resignations). The reason we reminisce is that this morning - after a long-weekend closed - UK Gilt yields are soaring once again... to their highest level since 1998 (and are a stunning 80bps above the Trussian highs) as worries intensified over local government elections and the impact of soaring energy prices on the economy. While bond investors around the world have signaled their discontent with faster inflation and potentially higher interest rates, the UK stands out as the most extreme example. As Bloomberg reports, the combination of Britain’s messy political landscape, with unpopular Prime Minister Keir Starmer likely to face a leadership challenge, feeble economy and strained government finances have made it a target for traders looking for a weak link. “The market has one eye on the fact that Starmer’s days are numbered, and if not numbered then a further move to the left of the political spectrum is inevitable in an attempt to head off support for the Green party,” said Lloyd Harris, head of fixed income at Miton Group. The UK 10-year yield has jumped 70 basis points since the start of the war, the biggest increase among a basket of developed markets tracked by Bloomberg over that period. The UK's problems are both domestic and foreign. This coming Thursday’s May local elections should keep focus high on the lingering risks of a flare-up in UK political or fiscal premium. Goldman Sachs traders believe that options markets are right to price-in relatively limited vol premium for the day itself. The larger risks are likely in the form of either leadership challenges to the PM, or a shift in focus back to a constrained fiscal position on account of the evolution of energy prices and Gilt yields throughout the energy shock, and both of these are likely less immediate. And even if these risks do materialise, we expect the impact on Sterling to come as bouts of currency underperformance rather than a more concerted trend lower, consistent with the pattern over the past year. However, in the minds of investors, big losses at the ballot box raise the chances that either Starmer or his replacement would have to boost government spending to win back disaffected voters, which would further pressure the UK’s finances. On top of that, the UK’s reliance on imported energy has left it vulnerable to an economic shock from the war in the Middle East. With oil prices stuck above $100, the fear is that faster inflation will force the central bank to hike interest rates even further. Markets are now pricing in three quarter-point rate hikes this year, up from two last week. Additionally, Bloomberg reports that some have speculated that the traditional buyers of UK bonds, like pension funds, aren’t as active in the market as they used to be, which is also helping to drive up yields. For decades, British defined-benefit pension funds bought long-dated bonds to match against their liabilities, allowing the UK to extend the average maturity of its issuance well beyond peers. Many of those programs are now winding down. While Starmer has outlasted Truss stay in office, the bond market appears to be demanding/predicting/fearing his fate may well be the same... and soon (for better or worse).
