Brent Johnson

Founder & CEO, Santiago Capital

The dollar will drain global liquidity before it falls — own gold for what comes after.

Background

Brent Johnson is an investment manager and CEO of Santiago Capital, a wealth management firm he founded. He is best known as the creator of the Dollar Milkshake Theory — a macroeconomic framework describing how the US dollar might strengthen significantly before its structural decline — which has become one of the most widely discussed ideas in global macro investing since he began presenting it publicly around 2018. Johnson entered the public financial discourse when he began sharing the Milkshake framework through media appearances, conference presentations, and podcast interviews, quickly gaining a following among professional investors, macro traders, and precious metals investors who found his dollar-bearish-yet-dollar-strengthening thesis intellectually provocative.

Johnson's background is in wealth management, and he approaches macro markets through the lens of global capital flows and liquidity dynamics rather than through pure monetary theory. Santiago Capital focuses on preserving and growing wealth for high-net-worth clients with particular emphasis on navigating large-scale macro dislocations. His media presence has grown substantially since 2019, and he is a frequent guest on financial podcasts and conference stages. His willingness to maintain a contrarian position within the contrarian community — arguing for near-term dollar strength while remaining long-term gold bullish — has made him one of the more distinctive and intellectually honest voices in the space.

Investment Thesis

The Dollar Milkshake Theory is Johnson's signature intellectual contribution to macroeconomic analysis. Its core insight is that the US dollar will experience a paradoxical strengthening phase before its structural decline — not because the dollar is fundamentally sound in absolute terms, but because it is the deepest, most liquid reserve currency in a world where all major governments are simultaneously printing money. Johnson's metaphor: every country's central bank is pouring monetary "milkshake" into its domestic economy, but the dollar, as the world's reserve currency, acts as the straw that sucks that liquidity toward US dollar-denominated assets. The result is dollar strengthening even during periods of significant Fed monetary expansion.

For gold investors, the Milkshake framework creates a counterintuitive near-term challenge: if the dollar strengthens significantly before its ultimate decline, gold — which is typically priced inversely to the dollar in international terms — may underperform in dollar terms even during periods of significant monetary debasement elsewhere in the world. Johnson is careful to note that gold can and does perform well in non-dollar currencies during the Milkshake phase, and that this distinction is important for global investors to understand. The framework explains why gold can frustrate dollar-denominated investors for extended periods even when the macro thesis for owning it remains sound.

Johnson's longer-term view is explicitly gold-positive: he argues that the Milkshake dynamic, once it has run its course — drawing in and then exhausting global capital flows toward the dollar — will leave the US in a structurally weakened monetary position and gold in a much stronger one. He is therefore a long-term gold bull who explicitly counsels patience with near-term dollar-driven volatility. His framework has also been useful in explaining periods of unusual co-movement between gold and the dollar (both rising in 2023-2024), which he attributes to the late-stage Milkshake dynamic where dollar-safe haven demand and gold-safe haven demand coexist temporarily.

Critiques & Limitations

The Dollar Milkshake Theory is intellectually stimulating and has generated accurate near-term predictions on dollar strength and gold-dollar co-movement dynamics. However, critics argue that the framework is inherently difficult to falsify on its own terms: if the dollar strengthens, the Milkshake is working; if the dollar weakens and gold rises, the Milkshake has completed. This structural unfalsifiability makes it challenging to use the framework as a risk management tool with clear entry and exit signals. Some macro economists also argue that Johnson overstates the uniqueness of the current dollar dynamic — the dollar has experienced similar strengthening cycles in the 1980s and 1990s without triggering the terminal Milkshake event he describes. Skeptics also note that the theory provides a rationale for holding gold regardless of near-term dollar performance, which conveniently aligns with the gold-positive conclusion Johnson already held before developing the framework.
