A lot of things.
The dollar is a global reserve currency and, for the last four years, it’s been trading at about 40 percent of the world’s reserve value.
The Fed, which is not a government agency, controls the supply and demand of dollars.
That means that if the Fed were to hike the dollar’s value, it would have to raise the interest rates of all of the major central banks.
If they raised interest rates, the dollar would lose purchasing power.
The Federal Reserve can also raise the dollar in response to foreign demand, as it did during the 2008-2009 global financial crisis.
And it can do so by buying foreign currency and selling dollars.
As a result, it can exert considerable pressure on the price of the dollar.
And if the dollar were to become more expensive than the euro, for example, or the pound, the Fed could buy those currencies and sell them at a lower price.
The problem is that the dollar has been a bit of a joke currency for a while now.
Its value has fluctuated widely over the last decade, fluctuating from around $1,500 to $2,000 in the years since 2009.
That volatility has led some observers to conclude that the value of the currency has been inflated, as if some foreign central bank had decided to print more money and raise the value.
And so the Fed has been able to push the dollar higher, albeit a bit more slowly than most observers would like.
This week, the Treasury Department released its first annual report on the US currency’s performance.
The report, which covered January through June, showed that the US had seen a slight improvement in the value and the demand for dollars over the previous 12 months.
But that improvement is not great, and the report showed that inflation has slowed.
But it does indicate that the Fed is willing to continue raising interest rates and that inflation will remain low.
The US economy, however, is not so rosy.
The GDP numbers in the Treasury report showed a slight contraction in the economy in December, the month before the US government announced that it was pulling the plug on a $4 trillion stimulus package.
But the report said that the economy will return to full employment in March.
And this is the key to understanding why inflation is so low.
Inflation has a lot to do with how much the economy is producing.
That is, the economy produces goods and services that consumers want.
If the economy were producing more goods and more services, then there would be a higher demand for the dollar, which would drive up the price.
In the real world, the US economy produces just enough goods and so the economy’s ability to keep prices down has to be very high.
For instance, if the price for a house is going to go up, then it will be more expensive to buy a house than to buy the same house at the same price elsewhere.
The same is true of the cost of living.
People in developed countries who live near cities have the best access to the best jobs and to higher wages because they can live close to jobs and earn higher salaries, which means they are less likely to be in debt.
The result is that people in cities have more disposable income than people in rural areas.
And when that income gets lower, they start to spend less, and so inflation gets higher.
The other big driver of inflation is that prices go up.
The real value of a dollar is determined by the value that the country’s people have to pay in taxes to support government spending.
So if the government spends more money than people actually need, they raise the price in order to compensate.
The resulting inflation pushes up the value for the US dollars.
The most important factor in determining the value or purchasing power of a US dollar is the price level.
The price level tells you how much people are willing to pay to buy goods and service in the US.
In order to make the prices of goods and the services available in the market more reasonable, the price should be set low.
And the lower the price, the more people are going to be willing to buy those goods and to pay for them.
That’s what the Fed did with the $4.5 trillion stimulus program.
In fact, that was the stimulus package that the Federal Reserve put out that year.
That package contained several items designed to help spur the economy.
But as the Fed was trying to make those items work, it decided to raise interest rates.
As I’ve written before, that is the Fed’s job.
The goal of the Fed, of course, is to keep interest rates low, to keep the economy from overheating and to keep inflation down.
But its goal is not to increase the amount of money in circulation, as some critics of the stimulus program claimed.
The central bank has no interest in the quantity of money that people are hoarding.
In other words, the central bank does not want to drive
