How does the price of oil influence the value of currency?
From an investor's standpoint, if the value of crude oil increases, economies that are oil dependent become more favourable (oil companies will be more profitable).  Therefore, investors will find that country's currency more attractive in the foreign exchange market. Because we need energy in the form of oil.  If more of our money is spent on oil, there is less money to spend on other items especially luxuries like dining out and new cars (ironically) Since there is less money available, the price of other things shift with it and the whole economy moves.  Since less money is available, the value of a single dollar goes up. Basically, it is because we as a species (let alone nations) are unbelievably dependent on having oil at this point in our existence. How do currency markets work? What factors are behind why currencies go up or down?
"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." "Overall, since gold has value in any currency (and is sort of the ultimate reserve currency), why would anyone want to currency hedge it? Because gold is (mostly) priced in USD. You currency hedge it to avoid currency risk and be exposed to only the price risk of Gold in USD.  Hedging it doesn't mean ""less speculative"". It just means you won't take currency risk. EDIT: Responding to OP's questions in comment what happens if the USD drops in value versus other major currencies? Do you think that the gold price in USD would not be affected by this drop in dollar value? Use the ETF $GLD as a proxy of gold price in USD, the correlation between weekly returns of $GLD and US dollar index (measured by major world currencies) since the ETF's inception is around -47%. What this says is that gold may or may not be affected by USD movement. It's certainly not a one-way movement. There are times where both USD and gold rise and fall simultaneously. Isn't a drop in dollar value fundamentally currency risk? Per Investopedia, currency risk arises from the change in price of one currency in relation to another. In this context, it's referring to the EUR/USD movement. The bottom line is that, if gold price in dollar goes up 2%, this ETF gives the European investor a way to bring home that 2% (or as close to that as possible)." There are various indexes on the stock market that track the currencies.  Though it is different than Forex (probably less leverage), you may be able to get the effects you're looking for.  I don't have a lot of knowledge in this area, but looked some into FXE, to trade the Euro debt crisis.  Here's an article on Forex, putting FXE down (obviously a biased view, but perhaps will give you a starting point for comparison, should you want to trade something specific, like the current euro/dollar situation). "Anthony Russell - I agree with JohnFx. Petroleum is used in making many things such as asphalt, road oil, plastic, jet fuel, etc. It's also used in some forms of electricity generation, and some electric cars use gasoline as a backup form of energy, petrol is also used in electricity generation outside of cars. Source can be found here. But to answer your question of why shares of electric car companies are not always negatively related to one another deals with supply and demand. If investors feel positively about petroleum and petroleum related prospects, then they are going to buy or attempt to buy shares of ""X"" petrol company. This will cause the price of ""X"", petrol company to rise, ceteris paribus. Just because the price of petroleum is high doesn't mean investors are going to buy shares of an electric car company. Petrol prices could be high, but numerous electric car companies could be doing poorly, now, with that being said you could argue that sales of electric cars may go up when petrol prices are high, but there are numerous factors that come into play here. I think it would be a good idea to do some more research if you are planning on investing. Also, remember, after a company goes public they no longer set the price of the shares of their stock. The price of company ""X"" shares are determined by supply and demand, which is inherently determined by investors attitudes and expectations, ultimately defined by past company performance, expectations of future performance, earnings, etc.. It could be that when the market is doing well - it's a good sign of other macroeconomic variables (employment, GDP, incomes, etc) and all these factors power how often individuals travel, vacation, etc. It also has to deal with the economy of the country producing the oil, when you have OPEC countries selling petrol to the U.S. it is likely much cheaper per barrel than domestic produced and refined petrol because of the labor laws, etc. So a strong economy may be somewhat correlated with oil prices and a strong market, but it's not necessarily the case that strong oil prices drive the economy..I think this is a great research topic that cannot be answered in one post.. Check this article here. From here you can track down what research the Fed of Cleveland has done concerning this. My advice to you is to not believe everything your peers tell you, but to research everything your peers tell you. With just a few clicks you can figure out the legitimacy of many things to at least some degree." Yes, this phenomenon is well documented.  A collapse of an economy's exchange rate is coincidented with a collapse in its equities market.    The recent calamities in Turkey, etc during 2014 had similar results. Inflation is highly correlated to valuations, and a collapse of an exchange rate is highly inflationary, so a collapse of an exchange rate is highly correlated to a collapse in valuations. "If there is a very sudden and large collapse in the exchange rate then because algorithmic trades will operate very fast it is possible to determine “x” immediately after the change in exchange rate. All you need to know is the order book. You also need to assume that the algorithmic bot operates faster than all other market participants so that the order book doesn’t change except for those trades executed by the bot. The temporarily cheaper price in the weakened currency market will rise and the temporarily dearer price in the strengthened currency market will fall until the prices are related by the new exchange rate. This price is determined by the condition that the total volume of buys in the cheaper market is equal to the total volume of sells in the dearer market.   Suppose initially gold is worth $1200 on NYSE or £720 on LSE. Then suppose the exchange rate falls from r=0.6 £/$ to s=0.4 £/$.  To illustrate the answer lets assume that before the currency collapse the order book for gold on the LSE and NYSE looks like: GOLD-NYSE   Sell (100 @ $1310) Sell (100 @ $1300) <——— Sell (100 @ $1280) Sell (200 @ $1260) Sell (300 @ $1220) Sell (100 @ $1200) ————————— buy (100 @ $1190) buy (100 @ $1180)   GOLD-LSE Sell (100 @ £750) Sell (100 @ £740) ————————— buy (200 @ £720) buy (200 @ £700) buy (100 @ £600) buy (100 @ £550) buy (100 @ £530) buy (100 @ £520) <——— buy (100 @ £500)   From this hypothetical example, the automatic traders will buy up the NYSE gold and sell the LSE gold in equal volume until the price ratio ""s"" is attained. By summing up the sell volumes on the NYSE and the buy volumes on the LSE, we see that the conditions are met when the price is $1300 and £520. Note 800 units were bought and sold.   So “x” depends on the available orders in the order book. Immediately after this, however, the price of the asset will be subject to the new changes of preference by the market participants. However, the price calculated above must be the initial price, since otherwise an arbitrage opportunity would exist." "From my limited experience with foreign exchange... Money is a commodity.. people buy it and sell it like other products.. if ""money"" is in demand the price goes up.. this is the case when a countries stocks are hot, and you need to purchase that countries currency to buy that stock... I've also seen the currency rise on news and speculation.  Many years ago, I administered foreign receivables... My job was to settle letters of credit from Britain... I remember on one ocassion Margaret Thatcher said something to upset the markets.. her remark caused the price of the UK pound to fluctuate." One interpretation of the above is that Pound (alongside US Dollar, Euro and other major curriencies), which forms the Forex basket of countries has dropped to less than 10% weightage in case of China's Forex holding. Now the question is where did this money go, this money probably have gone into Forex market to buy Yuan against Pound/Dollar etc. to bolster or strengthen Yuan. The currency reserve management is the 'wealth' management part and the 'currency' management part is what is known as 'central bank intervention' to stabilize the currency. "It's very hard to measure the worth of an abstract concept like money, particularly over long periods of time. In the modern era we have things like the Consumer Price Index (CPI) in the United States, where the Bureau of Labor Statistics literally sends ""shoppers"" out to find prices of things and surveys people to find out what they buy. This results in a variety of ""indexes"" which variously get reported by media outlets as ""inflation"" (or ""deflation"" if the change in value goes the other way). There are also other measurements available like the MIT Billion Prices Project which attempt to make their own reading of the ""worth"" of currencies. Those kinds of things are about the only ways to measure a currency's change in ""value to itself"" because a currency is basically only worth what one can buy with it. While it isn't ""all the world's currencies combined"", there is a concept of the International Monetary Fund's ""Special Drawing Rights (SDR)"", which is a basket of five currencies used by world central banks to help ""back"" each other's currencies, and is (very) occasionally used as a unit of currency for international contracts. One might be able to compare the price of one currency to that of the SDR, or even to any other weighted average of world currencies that one wanted, but I don't think it's done nearly as often as comparing currencies to the basket of goods one can buy to find ""inflation"". Even though one might think what would be important to measure would be overall Money Supply Inflation, much more often people care more about measuring Price Inflation. (Occasionally people worry about Wage Inflation, but generally that's considered a result of high Price Inflation.) In order to try to keep this on topic as a ""personal finance"" thing rather than an ""economics"" thing, I guess the question is: Why do you want to know? If you have some assets in a particular currency, you probably care most about what you'll be able to buy with them in the future when you want or need to spend them. In that sense, it's inflation that you're likely caring about the most. If you're trying to figure out which currency to keep your assets in, it largely depends on what currency your future expenses are likely to be in, though I can imagine that one might want to move out of a particular currency if there's a lot of political instability that you're expecting to lead to high inflation in a currency for a time." Most of the gold prices at international markets are USD denominated. Hence the prices would be same in international markets where large players are buying and selling. However this does not mean that the prices to the individuals in local markets is same. The difference is due to multiple things like cost of physical delivery, warehousing, local taxation, conversion of Local currency to USD etc. So in essence the price of Gold is similar to price of Crude Oil. The price of Oil is more or less same on all the markets exchanges, though there is small difference this is because of the cost of delivery/shipment which is borne by the buyer. However the cost of Oil to retail individual varies from country to country. Yes.  When the currency of a country appreciates, it benefits some groups and disadvantages others.  In particular, exporters suffer when a currency increases in value relative to other countries.  In a country like the US, where exporters are small relative to the economy, this isn't a big deal.  In germany, where exporters make up a big part of the economy, a currency increasing in value leads to large numbers of layoffs and other negative net effects to the economy. That value differs between a starving man and a man who never fears lack of food.  Let's take, instead, the value of your mother's affection.  Were you to have to pay for that affection, for her hugs, they would lose value.  Offering a price makes her affection worth LESS.  Therefore value is not tied to currency, nor is value indelibly tied to Capitalism.  Trading capital for your mother's affection negates the value of the affection. Stocks, gold, commodities, and physical real estate will not be affected by currency changes, regardless of whether those changes are fast or slow.  All bonds except those that are indexed to inflation will be demolished by sudden, unexpected devaluation. Notice: The above is true if devaluation is the only thing going on but this will not be the case.  Unfortunately, if the currency devalued rapidly it would be because something else is happening in the economy or government.  How these asset values are affected by that other thing would depend on what the other thing is.  In other words, you must tell us what you think will cause devaluation, then we can guess how it might affect stock, real estate, and commodity prices. The fiat currency is the basis for currency markets - that is, currency that is not made of precious metals.   The factors that influence what the value of a fiat currency are the state of the country's economy, what the gov't says the value should be, their fiscal policies, as well as what the currency is trading at.   And what the currency is trading at is a product of these factors as well as the typical factors which would affect any stock trading.  eHow has a great outline, here, which describes them. "if you have 401k with an employer already, has the following features: Your contributions are taxed That's only true if you're a high income earner. https://www.irs.gov/retirement-plans/2017-ira-deduction-limits-effect-of-modified-agi-on-deduction-if-you-are-covered-by-a-retirement-plan-at-work For example, married filing jointly allows full deduction up to $99,000 even if you have a 401(k). ""the timing is just different"" And that's a good thing, since if your retirement tax rate is less than your current tax rate, you'll pay less tax on that money."
