To The Moon

The moat nobody notices until it leaks I think investors still underestimate how unusual Berkshire Hathaway’s insurance machine really is. Most conglomerates collect capital and then allocate it. Berkshire’s genius was that it collected capital while often being paid to hold it. That is the magic of float. Warren Buffett effectively turned insurance liabilities into one of the cheapest investment funding sources in financial history. The problem is that float only stays magical if underwriting discipline remains exceptional. Berkshire’s float machine still works — just slightly less flawlessly That is why I think Berkshire Hathaway’s insurance division is entering its first genuine post-Buffett stress test. Not because the business is broken, and certainly not because GEICO suddenly forgot how to price car insurance, but because the early signs of competitive slippage are beginning to appear at precisely the moment leadership continuity matters most. Insurance culture is not something you can laminate onto a conference-room wall beside a framed quote about patience. It shows up operationally through pricing precision, claims efficiency, fraud detection, retention strategy and the willingness to walk away from unprofitable growth. Buffett understood that instinctively. The question now is whether Berkshire’s next generation can preserve it at scale. That sounds dramatic, but in insurance even tiny cracks compound over decades. Much like ignoring a suspicious engine noise because the radio still works. GEICO’s edge no longer looks untouchable The more important signal in 2025 is not that Berkshire still posted a combined ratio of 87.1. On the surface, that figure looks superb and most insurers would happily frame it in gold. The issue is what sits underneath it. Underwriting profitability weakened across Berkshire’s major insurance segments during 2025, suggesting the headline number flatters the broader trend. More importantly, competitors such as $Progressive(PGR)$ and The $Allstate(ALL)$ materially improved their loss and loss-adjustment-expense ratios while GEICO’s loss ratio moved in the opposite direction. That matters enormously because GEICO’s historic advantage was never just scale. It was operational efficiency. $Berkshire Hathaway(BRK.A)$ could tolerate insurance cyclicality because GEICO often priced risk more accurately, processed claims more cheaply and acquired customers more efficiently than peers through its direct-to-consumer model. I think that edge is narrowing. GEICO’s moat suddenly looks less lonely than investors remember Price return comparison: BRK.A, PGR, ALL — Nov 2025 to May 2026 Progressive, in particular, has quietly become one of the most technologically sophisticated insurers in the industry. Many investors still think of telematics as a marketing gimmick involving a small device monitoring how aggressively someone brakes near a supermarket car park. In reality, Progressive’s data advantage increasingly resembles a real-time underwriting laboratory. Its Snapshot platform continuously feeds driving behaviour into pricing models, allowing Progressive to refine risk segmentation faster than traditional insurers relying primarily on historical actuarial trends. That creates a structural advantage, not merely a cyclical one. The insurer with the fastest behavioural feedback loop can identify deteriorating risk pools earlier, raise prices sooner and retain the safest drivers more effectively. That is particularly important in today’s environment because modern vehicles are becoming dramatically more expensive to repair. A minor bumper collision now often involves sensors, cameras and software calibration that can make a routine accident resemble an IT support ticket with airbags. Progressive appears increasingly optimised for that world. GEICO still possesses enormous scale, but scale alone no longer guarantees underwriting superiority when pricing speed and data granularity are becoming the industry’s decisive weapons. Float is still valuable — just less magical Berkshire’s balance sheet remains exceptionally strong, with roughly $200 billion in cash and Treasury holdings alongside modest leverage for a company of its size. The financial fortress is still very much intact. But I think investors are focusing on the wrong question. The issue is not whether Berkshire has enough capital. It obviously does. The issue is whether its float is gradually becoming more expensive to generate. Float only becomes economically extraordinary when underwriting profits subsidise the liabilities supporting it. Berkshire historically achieved something close to that ideal. The company was effectively being paid to access enormous pools of investable capital. That dynamic now looks slightly weaker, and I think that matters more than most investors appreciate. If underwriting discipline deteriorates even modestly, Berkshire’s cost of float advantage could permanently rise. Investors often treat Berkshire’s float as structurally eternal, almost like a natural resource sitting beneath Omaha waiting to be deployed into equities and acquisitions. I do not think it is that simple. The economics of float are incredibly sensitive over long periods. A small deterioration in underwriting profitability may look insignificant in a single year, but over decades it meaningfully alters Berkshire’s compounding engine. That matters even more today because Berkshire’s investment portfolio has become increasingly conservative, with large Treasury allocations reducing the contribution from outsized equity gains. The market still trusts Berkshire — but with slightly tighter grip Ironically, the safer $Berkshire Hathaway(BRK.A)$ becomes financially, the more important underwriting precision becomes operationally. The succession issue is operational, not emotional Much of the market still discusses Buffett succession emotionally, as though Berkshire shareholders are collectively preparing for the final episode of a beloved television series. I think that framing misses the real issue entirely. The simultaneous leadership transitions at Berkshire and GEICO matter because underwriting culture is operational, not philosophical. You cannot inherit it simply by absorbing Buffett aphorisms or attending annual meetings long enough to memorise the Coca-Cola references. Underwriting discipline requires decentralised judgment combined with ruthless consistency. That balance becomes much harder to preserve during leadership transitions because incentives subtly evolve and competitive pressure never pauses politely for succession planning. One underappreciated point is that Berkshire’s decentralised structure worked brilliantly partly because Buffett himself reinforced behavioural discipline without needing formal intervention. His reputation alone shaped managerial behaviour across subsidiaries. Post-Buffett Berkshire may eventually require more oversight precisely because informal authority weakens. That creates an unusual paradox. Berkshire’s historic strength was autonomy. Sustaining underwriting discipline after Buffett may require slightly less of it. A quieter risk than investors realise I am not bearish on Berkshire Hathaway Inc. itself. The company remains financially extraordinary and operationally diversified in ways few corporations could realistically replicate. But I do think the market is beginning to confront a possibility it long ignored: Berkshire’s insurance engine may no longer be widening its competitive moat. That does not mean the moat disappears overnight. It means the economics gradually become less exceptional. Even legendary machines eventually depend on microscopic calibration For decades, Berkshire’s float behaved almost like a perpetual-motion machine for capital allocation. The danger is not that the machine stops working. The danger is that it quietly becomes less efficient while investors remain hypnotised by its glorious history. And in insurance, tiny inefficiencies have a nasty habit of compounding faster than premiums. @TigerStars @Daily_Discussion @Tiger_comments @Tiger_SG @Tiger_Earnings @TigerClub @TigerWire
