Global Asset Allocation: The Investment Strategy to Beat Inflation

When Kevin Warsh, former Federal Reserve governor, was nominated as the next Fed chair candidate, U.S. markets reacted immediately. The dollar strengthened, gold and silver prices recorded double-digit declines, and Bitcoin fell below $80,000.

Why did financial markets react so sensitively to Warsh's nomination? Likely because of his hawkish track record opposing additional quantitative easing, arguing it would trigger inflation. His forecasts at the time proved spectacularly wrong—he had overlooked price stability arising from international division of labor between Asian countries and Western developed nations.

What about now? With American isolationism becoming full-blown under Trump's second term, market liquidity policies are increasingly likely to trigger high inflation. Those of us who must live with inflation concerns need to consider appropriate countermeasures.

The most representative financial product for hedging inflation is inflation-linked bonds. These bonds pay interest linked to the consumer price index, issued in Korea as Korea Treasury Inflation-indexed Bonds (KTBi). They carry no credit risk due to government backing and perfectly match officially announced inflation rates, making them ideal for inflation hedging.

However, ordinary people's "real-world inflation" runs much higher, necessitating alternatives. I propose global asset allocation. According to our firm's Long-Term Capital Market Assumptions (LT-CMA), global equities offer a real expected return of 6.7% annually under currency-exposed investment assumptions. This means investing in global equities could yield approximately 6.7% above consumer price inflation annually.

The problem is returns aren't guaranteed like inflation-linked bonds. Global equity volatility runs at 12.4% annually. Assuming normal distribution, the probability of one-year investment returns falling below consumer price inflation (failure probability) reaches 29.5%. Gold, another inflation hedge, offers higher real expected returns at 8.5% but with higher volatility at 17.8%. Its failure probability is 31.6%—also higher than global equities.

Global asset allocation solves these single asset class investment problems. Mixing global equities and gold at a 4:1 ratio produces real expected returns of 7.6% with volatility dropping to 10.5%, reducing failure probability to 23.5%. An optimal portfolio comprising five asset classes—Korean equities, U.S. growth stocks, U.S. high-yield bonds, Korean government bonds, and gold—can lower portfolio volatility to approximately 9.1% while maintaining real expected returns at 7.6%. Failure probability drops to around 20.0%. Through global asset allocation, we can achieve our investment goal of beating consumer price inflation with higher probability.
