Warren Buffett: Why Your Portfolio Should Always Be 10% Cash

Berkshire Hathaway Capital Allocation & Partnership Dynamics

Key Concepts:

• Cash Reserve: Maintaining a substantial cash holding ($20 billion) for opportunistic investments and weathering economic downturns.
• Financial Independence: Avoiding reliance on external financing (bank lines, credit) to ensure operational stability.
• Capital Allocation: The process of deciding how to deploy capital – within operating companies or at the parent (Berkshire Hathaway) level.
• Compound Interest: The principle of earning returns on both initial investment and accumulated interest.
• Partnership Dynamics: The collaborative relationship between Warren Buffett and Charlie Munger, characterized by disagreement without argument.

I. The Importance of a Substantial Cash Reserve

Warren Buffett emphasizes the critical importance of maintaining a $20 billion cash reserve at Berkshire Hathaway. This isn’t a rigid rule, but a foundational principle: “We always will have $20 billion around Berkshire. We will never be dependent on the kindness of strangers.” He draws a parallel to Blanche Dubois from A Streetcar Named Desire, highlighting the dangers of relying on external support. The rationale is to ensure Berkshire’s resilience during unforeseen economic crises, stating that “there will be some time in the next hundred years…where we cannot depend on anybody else…to keep our own strength and to maintain our operations.”

Buffett recounts a past instance where Berkshire lent Harley-Davidson money at a 15% interest rate when short-term rates were only 0.5%, illustrating their willingness to deploy capital even in challenging situations. He likens cash and credit to “oxygen,” essential and unnoticed until absent. The goal is to avoid a position where a lack of liquidity becomes the sole focus, hindering Berkshire’s ability to pursue advantageous opportunities. Above the $20 billion, Berkshire actively seeks “ways to invest it intelligently,” and has been successful in doing so.

II. Opportunities for Capital Deployment & the Role of Operating Companies

Charlie Munger highlights the benefit of Berkshire’s current position, stating, “We’re very lucky to have these businesses that can employ a lot of new capital at very respectable rates.” He emphasizes that this wasn’t always the case, but Berkshire’s current portfolio – including Mid-American Energy and Burlington Northern Railroad – provides consistent opportunities for profitable reinvestment. Buffett and Munger express enthusiasm for deploying capital in a low-interest-rate environment, citing opportunities like collaborations with 3G Capital and Hind. They acknowledge that opportunities will arise, and “compound interest will catch up with us.”

III. Capital Allocation Strategy: Parent Company vs. Operating Companies

Responding to a shareholder question, Buffett explains Berkshire’s approach to capital allocation between the parent company and its operating subsidiaries. The $20 billion minimum reserve is the primary focus, but the precise location of funds isn’t a major concern. Buffett states, “We don’t really care too much where that 20 billion minimum is.”

Berkshire generally doesn’t enforce strict “sweep accounts” (automatic transfer of funds to the parent company) like many conglomerates. Instead, operating companies often retain significant cash reserves. This is acceptable because interest rates are such that funds can earn comparable returns whether held at the parent level (around 5 basis points) or within the subsidiaries. Buffett emphasizes his awareness of where the cash resides and his ability to access it when needed, stating, “I know where the cash is and I know when we’re going to need cash.”

He describes a hands-off approach to many subsidiaries, even admitting to rarely interacting with the manager of one particular company, yet knowing he can access funds when necessary. He characterizes his approach as adaptive, adjusting to the specific needs of each company.

IV. The Buffett-Munger Partnership: A Model of Disagreement Without Conflict

Buffett and Munger address the longevity and success of their partnership, which began in 1965. They emphasize that despite frequent disagreements – “We’ve disagreed on a lot of things…in those 55 years” – they have never engaged in an argument. Buffett recounts consulting Munger on the Coca-Cola investment, noting they “thought alike.” However, they are comfortable with differing opinions, recognizing that if one misses an opportunity, the other likely will as well.

Munger acknowledges that he is generally more cautious than Buffett, recalling being labeled “the abominable no man” by Buffett. Buffett concedes that he is likely more inclined towards action. He stresses that their disagreements never lead to animosity.
