Base Currency Thinking / 本币思维

Base currency thinking is 176.纽约一年：一个悲观主义者的活法｜725沙龙实录’s household rule for dealing with exchange-rate anxiety. Instead of asking whether RMB or the dollar will appreciate, [[DavidWeng|大卫翁]] asks where a person expects to live and spend in the future. That location and liability structure define the household’s real base currency.

The concept extends Currency Risk from asset returns into life planning. A person who will spend most future money in RMB faces different risk from a person with dollar rent, tuition, medical costs, or retirement expenses. Once the base currency is clear, currency exposure can be sized as a real hedge or allocation need rather than a pure FX forecast.

Key Claims

• Currency decisions should begin with future spending and liabilities, not exchange-rate prediction.
• A currency can look attractive as an asset while still creating mismatch for the household’s real expenses.
• Exchange-rate forecasting is especially hard for ordinary investors, so the controllable question is exposure fit.
• Base-currency thinking connects portfolio allocation, immigration plans, education plans, and long-term living location.
• The rule complements gold or other spare-tire assets but does not make them substitutes for identifying one’s real spending unit.
