What effect would currency devaluation have on my investments?
My question boiled down: Do stock mutual funds behave more like   treasury bonds or commodities? When I think about it, it seems that   they should respond the devaluation like a commodity. I own a quantity   of company shares (not tied to a currency), and let's assume that the   company only holds immune assets. Does the real value of my stock   ownership go down? Why? On December 20, 1994, newly inaugurated President Ernesto Zedillo   announced the Mexican central bank's devaluation of the peso between   13% and 15%.  Devaluing the peso after previous promises not to do so   led investors to be skeptical of policymakers and fearful of   additional devaluations. Investors flocked to foreign investments and   placed even higher risk premia on domestic assets. This increase in   risk premia placed additional upward market pressure on Mexican   interest rates as well as downward market pressure on the Mexican   peso.  Foreign investors anticipating further currency devaluations   began rapidly withdrawing capital from Mexican investments and selling   off shares of stock as the Mexican Stock Exchange plummeted. To   discourage such capital flight, particularly from debt instruments,   the Mexican central bank raised interest rates, but higher borrowing   costs ultimately hindered economic growth prospects. The question is how would they pull this off if it's a floatable currency.  For instance, the US government devalued the US Dollar against gold in the 30s, moving one ounce of gold from $20 to $35.   The Gold Reserve Act outlawed most private possession of gold, forcing   individuals to sell it to the Treasury, after which it was stored in   United States Bullion Depository at Fort Knox and other locations. The   act also changed the nominal price of gold from $20.67 per troy ounce   to $35. But now, the US Dollar is not backed by anything, so how do they devalue it now (outside of intentionally inflating it)?  The Hong Kong Dollar, since it is fixed to the US Dollar, could be devalued relative to the Dollar, going from 7.75 to 9.75 or something similar, so it depends on the currency. As for the final part, "does the real value of my stock ownership go down" the answer is yes if the stock ownership is in the currency devalued, though it may rise over the longer term if investors think that the value of the company will rise relative to devaluation and if they trust the market (remember a devaluation can scare investors, even if a company has value). Sorry that there's too much "it depends" in the answer; there are many variables at stake for this.  The best answer is to say, "Look at history and what happened" and you might see a pattern emerge; what I see is a lot of uncertainty in past devaluations that cause panics.
