Berkshire Hathaway (NYSE: BRKA) (NYSE: BRKB) has delivered stellar long-term returns, and one major reason why is that it leans heavily on insurance to drive its long-term growth.
In the second quarter, the company saw its float, or the cash generated from premiums collected before claims are actually paid out, jump $1.1 billion to a whopping $177.5 billion. This growing float has been a cornerstone of Berkshire's growing cash pile and ability to make strategic investments across a range of industries.

However, Berkshire's underwriting profit actually dipped during the second quarter. Despite this, the conglomerate saw steady growth across other sectors, showing why Berkshire can continue to deliver for investors.
Berkshire Hathaway is a massive conglomerate with businesses across manufacturing, energy, transportation, utilities, consumer products, and insurance, of course. Within its insurance segment, Berkshire owns automotive insurer GEICO, along with insurers across the industry, covering commercial, specialty, and reinsurance.
Insurance has been crucial for Berkshire's long-term success because it provides the company with a massive cash stockpile through its float. Float represents cash collected before paying out claims, and Berkshire invests it in safe U.S. Treasuries. Claims tend to be predictable over time, and as collected premiums outpace claims, Berkshire's cash stockpile grows steadily over a long time horizon.
In the second quarter, Berkshire's float climbed to $177.5 billion. The company invests this specific capital primarily in U.S. Treasuries. Combined with its other investments, Berkshire closed the quarter with $324.9 billion in U.S. Treasuries and another $323.8 billion in equities.
Float grew despite the company's insurance underwriting after-tax earnings falling 13% year over year in the second quarter. The drop came amid higher claims costs in its GEICO auto insurance business. In the quarter, GEICO's loss ratio rose to 76.6%, up from 71.8% in the prior year.
The rising loss ratio reflects higher automotive claims costs. On top of this, GEICO also saw expenses rise as it increased advertising spend in the period.
Despite this, Berkshire saw excellent performance across its other insurance businesses, Berkshire Hathaway Primary Group and Berkshire Hathaway Reinsurance Group, thanks to lower-than-expected losses and solid premium growth.
Investors in Berkshire should keep an eye on its insurance operations, which have driven a large chunk of the company's long-term value. However, despite the drop in insurance earnings, Berkshire Hathaway continued to grow across its businesses, with second-quarter operating earnings rising 16% to nearly $13 billion. Its manufacturing, service, and retail businesses drove growth during the period.
The company also became a net buyer of equities for the first time in three and a half years, increased its Alphabet stake to $40 billion, and still has $365 billion in capital to put to work. For investors seeking a quality stock that has built-in diversification, Berkshire Hathaway remains an excellent stock to own today.

Four leading AI models discuss this article
"Berkshire is becoming overly reliant on interest income from its Treasury holdings, masking a structural decline in core insurance underwriting efficiency."
The market is fixating on the $177.5 billion float as a static safety net, but the 13% drop in underwriting profit is a warning shot. GEICO’s loss ratio jumping to 76.6% indicates that inflationary pressure on vehicle repair and medical costs is outpacing premium adjustments. While Berkshire's $324.9 billion in U.S. Treasuries provides a lucrative yield buffer in a high-rate environment, the conglomerate is essentially shifting from an underwriting-driven value creator to a Treasury-yield play. If the Fed pivots to aggressive rate cuts, the 'easy money' from that massive cash pile will evaporate, exposing the underlying operational margin compression in their insurance and manufacturing segments.
The rise in GEICO's loss ratio is a tactical choice to prioritize market share and premium growth over immediate underwriting profit, which historically precedes periods of superior long-term compounding for Berkshire.
"GEICO's 490 bps loss ratio deterioration signals that Berkshire's most reliable float engine is underwriting at a loss, making float growth a liability rather than an asset unless margins recover."
The article frames float growth as unambiguously positive, but the 13% underwriting profit decline is the real story. GEICO's loss ratio jumped 490 basis points to 76.6%—that's a deteriorating underwriting business, not a temporary blip. Float is only valuable if Berkshire earns positive underwriting spreads; otherwise it's just expensive leverage. The article buries that GEICO raised advertising spend aggressively, suggesting competitive pressure in auto insurance is intensifying. Yes, other insurance segments performed well and non-insurance earnings rose 16%, but the core float engine—GEICO—is showing structural stress that float growth alone cannot mask.
Float growth to $177.5B and a 16% rise in operating earnings across the conglomerate suggest the insurance headwind is manageable and priced in; Berkshire's $365B dry powder and equity buying spree indicate management confidence that current valuations offer better returns than holding cash.
"Berkshire’s long-term upside hinges on float economics and disciplined deployment; if underwriting weakness persists or investment returns disappoint, the stock’s upside could be more dependent on macro moves than on insurance discipline."
Berkshire's quarterly release shows the insurance float remains a massive, durable capital engine, but the headline positives mask real insurance-margin pressure. Underwriting profit fell 13% YoY, and GEICO's auto loss ratio rose to 76.6% amid higher claims and ad spend. That implies float-driven earnings could soften if claims inflation or catastrophe costs persist. The rest of Berkshire’s earnings come from non‑insurance operations and a sizable investment book, including a larger Alphabet stake; however, those gains are more cyclical and rate/market sensitive. While the balance sheet remains formidable and capital to deploy is massive, near-term upside rests on investment performance and continued premium growth, not insurance underwriting alone.
The strongest case against this stance is that Berkshire has repeatedly shown it can translate float into durable compounding, so even if underwriting margins wobble in the near term, skilled capital allocation and a growing investment book could still drive outsized earnings. A sustained market rally or insurance cycle tailwinds could mask near-term underwriting headwinds.

"The rising loss ratio is a calculated trade-off for market share rather than a sign of structural underwriting decay."
Gemini and Claude are obsessing over the 76.6% loss ratio as a structural failure, but they are ignoring the deliberate pivot in Berkshire’s underwriting cycle. GEICO is intentionally trading short-term margin for long-term customer acquisition in a hardening market. The real risk isn't the loss ratio—it's the massive concentration in Apple and the tax-drag from the recent equity sales. If the market corrects, Berkshire’s 'dry powder' is effectively a hedge, not just a yield play.
"Float value collapses if underwriting spreads remain negative; the Treasury pile is a symptom of insurance weakness, not a strength."
Gemini's 'deliberate pivot' claim needs scrutiny. GEICO's ad spend surge and loss-ratio deterioration could signal competitive desperation, not strategic choice. More critically: nobody's quantified the float's actual return. If GEICO's underwriting spread turns negative and stays there, float becomes a liability masquerading as an asset. Berkshire's $324.9B Treasury yield masks whether insurance operations are actually generating alpha or just funding Treasury holdings at the Fed's rate.
"Float's value isn't limited to positive underwriting margins; Berkshire's investment engine and capital allocation provide ongoing optionality even amid auto-underwriting headwinds."
Responding to Claude: I disagree that float only matters if underwriting spreads stay positive. Berkshire’s float is a multi-fuel engine: underwriting, investment income, buybacks, and disciplined capital allocation can still compound even with a weak auto line. The overlooked risk is a prolonged equity-market drawdown or higher catastrophe losses that compress investment returns and funding costs; Berkshire’s moat extends beyond current underwriting margins, so don’t discount the optionality of the investment book.
