The FTSE 100 remains volatile as investors weigh the implications of fresh US attacks on Iran, with the index experiencing a seesaw effect throughout the session.
However, for Britain's small business owners, a more pressing concern lies in the bond market, where gilt yields have reached their highest level since 10 June, exceeding 4.9 per cent.
According to Susannah Streeter, chief investment strategist, investors are becoming increasingly skittish, with early gains evaporating on the FTSE 100 as they weigh the likely outcome of the latest round of military action.
The US and Iran have both hit targets in the region, with President Trump declaring the ceasefire to be over, yet hinting at the possibility of fresh negotiations.
Streeter notes that despite both sides continuing to talk tough, a door may be opening to fresh negotiations, which could have a positive impact on the market.
There is some relief on the cost front, with Brent crude retreating to around $77 a barrel, easing fuel and freight bills that hit small firms hardest.
Mining stocks have rebounded, with gold and silver producers gaining as easing oil prices soothed inflation worries and nudged the dollar lower, making dollar-priced commodities more attractive to international buyers.
However, nobody in the market is treating the pullback as a turning point, and owner-managers are concerned that the calm may prove temporary, with energy costs surging again just as budgets for the second half of the year are being set.
Streeter warns that if energy prices start climbing again, higher costs would rapidly ripple through businesses across multiple sectors, while pricier fuel would eat into household budgets and encourage more cautious consumer spending.
The potential for an energy spike would also make cheaper borrowing harder to deliver, with CPI inflation at 2.8 per cent in the year to May and the Bank of England holding Bank Rate at 3.75 per cent.
Furthermore, gilt yields, which feed through to the swap rates underpinning business loans, commercial mortgages, and asset finance, are being propped up by turbulence closer to home.
Investors are weighing what a potential change in leadership could mean for tax and spending plans, an uncertainty that is already unsettling the majority of SME owners, according to Business Matters research.
Streeter notes that with so many moving parts, investors are demanding a bigger premium to lend to the UK, and gilt yields look set to remain sensitive to every fresh political and geopolitical twist.
For small firms, the practical message is clear: cheaper oil is welcome, but with borrowing costs pinned near recent highs and the political weather changeable at home and abroad, this is a moment for stress-testing cash flow rather than banking on calmer markets.
