How to Own the World

by Andrew Craig

View on Amazon

Andrew Craig is a British investor and writer who spent years in professional finance before concluding that the investment industry systematically obscures simple truths to justify its fees. How to Own the World is his attempt to share those truths in plain English with retail investors who have been made to feel that investing is too complex for non-professionals.

The book's central argument is that inflation is the silent destroyer of wealth and that leaving money in a cash savings account is not a safe choice but a guaranteed way to lose purchasing power over time. Craig uses historical data to show that the real value of cash savings has been eroded in every decade since the Second World War.

The asset allocation framework Craig proposes spreads capital across five asset classes: equities, bonds, property, commodities, and cash. The principle - that diversification across uncorrelated asset classes reduces portfolio volatility without necessarily reducing returns - is grounded in decades of academic research.

The chapter on global versus domestic investing is particularly valuable for UK readers who have historically over-weighted British equities. Craig demonstrates that the UK stock market represents roughly three percent of global market capitalisation. A UK investor holding only UK equities is missing 97 percent of the world's investable universe.

The currency chapter addresses a topic that most UK personal finance books ignore entirely. Craig explains how holding assets in multiple currencies provides a natural hedge against sterling weakness and why this matters for British investors whose income and spending are denominated in pounds.

The book was updated in 2018 and some platform recommendations reflect that date. The underlying investment principles remain sound. Craig's treatment of gold as a portfolio diversifier and inflation hedge is more positive than most mainstream UK financial advice.

Key Takeaways

  • Inflation erodes cash savings - leaving money in a bank account is a guaranteed real loss
  • Diversify across five asset classes: equities, bonds, property, commodities, and cash
  • The UK stock market is only 3 percent of global market cap - global diversification is essential
  • Currency diversification provides a natural hedge against sterling weakness
  • Low-cost global index funds and ETFs are the most practical vehicle for retail investors
  • Time in the market across multiple asset classes is more powerful than any single asset selection
  • The investment industry makes investing seem complex to justify fees - it need not be

Who Should Read This

UK savers who have significant cash in savings accounts and have not yet moved into investment markets, anyone who holds only UK equities and wants to understand global diversification, and anyone who wants a plain-English introduction to multi-asset investing written specifically for British investors.
