For much of the past half-century, Warren Buffett’s Berkshire Hathaway has stood as the gold standard of insurance-based capitalism — a model of disciplined underwriting and patient investment that shaped global markets from Omaha to London. But as the 95-year-old prepares to relinquish the chief executive’s role at the end of this year, analysts and investors alike are questioning whether the conglomerate’s remarkable run has finally peaked.
This week, the investment bank Keefe, Bruyette & Woods (KBW) issued a rare underperform rating on Berkshire’s shares, arguing that the group’s complex web of insurance, energy, and industrial businesses faces mounting headwinds. The firm trimmed its price target for Berkshire’s Class A shares to $700,000 and warned that “many things [are] moving in the wrong direction.”
The KBW report, led by analyst Meyer Shields, pointed to a convergence of pressures — falling interest rates, weaker insurance margins, and the phase-out of renewable-energy tax credits — compounded by what it called “Berkshire’s historically unique succession risk.”
Mr Buffett will hand day-to-day control to Greg Abel, a long-time lieutenant who oversees non-insurance operations. The legendary investor will remain chairman, but the psychological impact of his stepping back is already being felt: the company’s shares have lagged the S&P 500 by nearly 30 percentage points since his announcement in May.
At the heart of the concern lies Berkshire’s global insurance empire — the financial engine that has long powered its acquisitions and investments. KBW warned that GEICO, the group’s vast American motor insurer, is entering a tougher phase as it cuts rates and boosts marketing spend to claw back market share from Progressive and other competitors. Those moves, Shields said, will lift claims costs as a percentage of premium income after two years of improvement.
The reinsurance division is also facing gentler pricing following a calm hurricane season, reducing opportunities for high-margin catastrophe business. “We think insurance profitability could weaken further,” KBW wrote, noting that underwriting income had already dipped in the second quarter.
Berkshire’s insurance operations still produced some $11 billion in underwriting profit last year and a formidable $171 billion in float — the investable capital generated from unclaimed premiums. Yet with interest rates now edging lower, returns on the company’s $344 billion in cash and Treasury holdings are expected to soften, weakening one of its most dependable earnings streams.
For the British market, Berkshire’s insurance influence is anything but abstract. The group maintains a significant UK presence through several regulated entities, centred on London’s commercial lines sector.
Berkshire Hathaway International Insurance Limited (BHIIL), headquartered at Fenchurch Place in the City, provides property, casualty, and specialty cover worldwide and carries an AA+ rating from S&P through its parent. It is joined by the UK branch of Berkshire Hathaway European Insurance DAC, which supports cross-border underwriting between Britain and the EU.
Meanwhile, Berkshire Hathaway Specialty Insurance (BHSI) has built a visible London and Manchester operation offering property, casualty, professional indemnity, and more recently, accident and health products, including group personal accident and business travel policies. BHSI’s expansion into A&H underscores Berkshire’s intention to grow selectively in niche and mid-market lines even as the wider conglomerate slows.
These businesses have given Berkshire a strong foothold in the London Market and a bridgehead into continental Europe — part of the decentralised structure that has long defined its insurance empire.
Outside insurance, the picture is similarly mixed. Burlington Northern Santa Fe, the freight railway that links the US heartland to Pacific ports, remains exposed to renewed trade friction between Washington and Beijing. At Berkshire Hathaway Energy, the One Big Beautiful Bill Act is accelerating the phase-out of clean-energy tax incentives, eroding returns on renewable projects that had once been a source of steady growth.
The deeper concern, however, is psychological. For decades, Mr Buffett’s reputation as an almost preternatural allocator of capital has conferred a valuation uplift known as the Buffett premium. That confidence, KBW warned, may dissipate once investors can no longer rely on his presence. “Limited disclosure about future governance will probably deter investors once they can no longer rely on Mr Buffett’s presence,” the firm said.
Since May, Berkshire’s stock has slipped about 10 per cent from record highs, underperforming the broader market despite continued profitability across most divisions.
For UK and international insurance professionals, Berkshire’s slowdown carries symbolic and practical implications. The group’s float — still the envy of global peers — provides vast capacity in reinsurance and specialty markets, influencing pricing from London to Singapore. If margins at GEICO tighten and reinsurance appetite moderates, capacity could become scarcer, altering dynamics across the global risk-transfer ecosystem.
Even so, few in the market expect Berkshire’s retreat to be permanent. Its balance sheet remains one of the strongest in global finance, and its conservative reserving approach continues to set the benchmark for underwriting prudence.
Berkshire will release its third-quarter results on 1 November — the first meaningful test of how investors and underwriters alike are adjusting to the coming post-Buffett era. Whether the world’s most admired insurance group has truly peaked, or merely paused, will soon become clearer.
