This drives up Treasury yields and interest rates. Treasury note yields are the main driver of mortgage rates. It can mean that foreign central banks and sovereign wealth funds are holding fewer dollars, too. This lowers the demand for dollars. A weaker dollar buys less in foreign goods. This increases the price of imports, contributing to inflation.
As the dollar weakens, investors in the benchmark year Treasury and other bonds sell their dollar-denominated holdings. Contracts for oil and other commodities are usually denominated in dollars. As a result, historically, there has been an inverse relationship between the value of the dollar and commodities prices.
Essentially, as the value of the dollar falls, the dollar-denominated prices of these commodities must rise to reflect their unchanged intrinsic value. On the plus side, a weakening dollar helps U. Their goods will seem cheaper to foreigners. However, if enough investors leave the dollar for other currencies, this could cause a dollar collapse.
This is largely a theoretical consideration. The probability of this development is extremely low, as discussed in the closing section of this piece.
In , the Foreign Account Tax Compliance Act required foreign banks and other financial institutions to disclose information regarding income and assets held by U.
Its goal is to root out wealthy U. It also wants to stop foreign banks from using tax evasion as a profitable line of business. Many were worried foreign banks will drop U. This made London the first trading hub for the yuan outside of Asia. This is one way China is trying to encourage central banks to increase their holdings of the Chinese yuan.
It is the biggest potential threat to the value of the dollar. China would like the yuan to replace the dollar as the world's reserve currency. Since then, China has been devaluing the yuan against the dollar. It is doing so because its leaders are worried the economy is growing too slowly. The devaluation objective is largely accomplished via the continual purchase of U.
Over half of the current account deficit is owed to foreign countries and hedge funds. The dollar strengthened during the recession , as investors sought a safe haven in comparison to other currencies. When economists talk about a currency such as the dollar "collapsing," they're referring to a sudden, steep decline in the value of that currency, to the point where it's worth only a tiny fraction of its previous value. For people using the currency, the collapse manifests itself in hyperinflation -- extreme price increases.
It's not that the apple has gotten more valuable; it's that the dollar got less valuable. Currency collapses have produced astounding images of people using stacks of money for the smallest purchases and of governments printing banknotes in ridiculously high denominations, such as the trillion-dollar bill that Zimbabwe printed in the s and which, according to "The Wall Street Journal," still wouldn't even pay for local bus fare.
During a currency collapse, hyperinflation locks an economy into a "wage-price spiral," in which higher prices force employers to pay higher wages, which they pass on to customers as higher prices, and the cycle continues. Meanwhile, the government cranks out currency to meet demand, making inflation even worse. Excessive liquidity combined with a lack of the support from real economy is bound to bring serious side effects. Even the approach could help the US economy endure current predicament, the followed problems of recall the liquidity from market and to pay back the surging debts still requires proper solution.
It is still too early to give an optimistic forecast on the US economy prospects this year. The structural problems within the US economy for a long time are still not addressed, and the manufacturing has not been brought back to the US.
The US' participation in global economy is still not sufficient. A weak economy and poor employment are not conducive for the dollar to reverse current weakness. Additionally, emerging economies including China are improving economic strength, which will support these economies' currency to go strong. The shift and reshuffle of global currency system is bound to happen, in which dollar will see a weakening trend.
The fundamental weakness of the U. This weakness is shared by every other major national currency in the world and is perceived as normal in the modern age. However, as recently as the s, it was considered a somewhat radical proposition.
Without the discipline imposed by a commodity-based currency standard such as gold , the worry is that governments might print too much money for political purposes or to conduct wars. If the Federal Reserve creates money and the U. Fortunately for the United States, virtually every alternative currency is backed by similar economic policies.
Even if the dollar faltered in absolute terms, it may still be stronger globally, due to its strength relative to the alternatives. There are some conceivable scenarios that might cause a sudden crisis for the dollar. The most realistic is the dual-threat of high inflation and high debt, a scenario in which rising consumer prices force the Fed to sharply raise interest rates. Much of the national debt is made up of relatively short-term instruments, so a spike in rates would act like an adjustable-rate mortgage after the teaser period ends.
If the U. Another option would involve some major power, such as China or a post-European Union Germany, reinstating a commodity-based standard and monopolizing the reserve currency space. However, even in these scenarios, it is not clear that the dollar necessarily would collapse. The collapse of the dollar remains highly unlikely. Of the preconditions necessary to force a collapse, only the prospect of higher inflation appears reasonable.
Foreign exporters such as China and Japan do not want a dollar collapse because the United States is too important a customer. And even if the United States had to renegotiate or default on some debt obligations, there is little evidence that the world would let the dollar collapse and risk possible contagion.
