Ben Bernanke and the Federal Reserve have kept interest rates low for some time. Interest rates lie somewhere below a quarter point and a zero, giving people very little reason to save. Why should you save money when inflation could work against you and the money will not grow?

Low interest rates also work to reduce the cost of borrowing. This could help businesses that want to expand, or the federal government that has trillions of dollars of debt that it needs to finance.

Gold jumped to $1033 per ounce on Tuesday, hitting a record high. Oil rose $1 per barrel. The December dollar contract is at $76.53, down $0.305 (as of 8:11 EDT).

Why is gold moving up? A news story in The Independent, a British paper, reported that secret talks are underway to dump the dollar as the currency for oil transactions. Included in the talks were China, Russia, Japan and France. They want is to replace the U.S. dollar with a basket of currencies and gold.

What's next for the dollar? Good question. It depends on which set of economic data points you emphasize, or which mindset/narrative you believe is dominant in the currency markets.

After a nearly two-week decline against the world's other, major currencies, the dollar see-sawed with the euro for the upper hand Friday, as dollar bulls and dollar bears each tried to make their case that their view was more supported by current conditions. The dollar strengthened one-half cent versus the euro to $1.4696 and about 1.8 cents versus the British pound to $1.6260 on Friday at mid-day.

As Melly Alazraki noted earlier today, McDonald's Corp. (NYSE: MCD) is one of many heavy hitters to take the earnings stage today. Unfortunately, the fast-food firm didn't exactly impress with its latest quarterly figures; the company struggled under the weight of weak sales during the month of June, and saw its second-quarter profits slide 8% year-over-year as a result.

Specifically, the Big Mac parent raked in net income of $1.09 billion, or 98 cents per share, compared to its year-ago results of $1.19 billion, or $1.04 per share. Excluding a one-cent gain, earnings weighed in at 97 cents per share. McDonald's reported that strength in the U.S. dollar negatively impacted its quarterly results by about 9 cents per share.

This is unbelievable! California (my home state) is going to issue I.O.U.'s to seniors, disabled and welfare recipients starting tomorrow because our State Legislature cannot agree on a budget. This is outrageous beyond belief!

Next time someone refers to California as the "Golden State" the laughter from all corners of the nation will be deafening. They say that California Bonds and Schools will not be affected.

What I want to know is whether the politicians will be getting paid in I.O.U.'s. There are many people in the land of the petition and ballot initiative that would be in favor of a law that says the politicians do not get paid for twice the time it takes to settle the budget beyond yesterdays (June 30) deadline.

The British pound (CME: $BPY) hit $1.60 for the first time in more than half a year this morning, thanks to improved service company sentiment and an increase in mortgage approvals. A rise in consumer confidence in the United States increased risk appetite and lifted the pound, as well.

The news was good enough for a 0.5% gain for the pound against the dollar, a 0.6% increase relative to the euro and 1% against the yen (CME: /JY\M09).

In one of my previous blogs: Is the stock market spring loaded? I coined the phrase Lightspeed Inflation in reference to the rate at which the government was able to dilute our currency. It is time we stopped referring to the government's over spending as "running the printing presses".

We have reached a point, given our maximum note size of $100, that we would actually be better off if the government did have to print the money. Now they can just add whatever amount they want to the balance sheet electronically.

The U.S. dollar is getting hammered in world markets after the Federal Reserve announced plans to buy $300 billion in long-term U.S. Treasuries. When the Fed buys bonds, it creates more money and that money is pumped into the economy. More dollars have the effect of weakening a country's currency. This is what is causing the present sell off in the dollar.

For investors this creates a new dilemma. For the short term, there will be pressure on the dollar. Should you then bet on further weakness and sell short the U.S. currency? That might work. On the other hand, if the Fed is right and the U.S. economy recovers quicker than other world economies, the dollar would gain strength against other currencies. So then do you seize this opportunity and use the present dollar weakness as a chance to buy the U.S. dollar?

If we learned anything from Tuesday's market, it's that it is spring loaded, pun intended. The Dow Jones Industrial Average was up 379.44 or 5.8%, closing at 6,926.49. The NASDAQ and S&P were up even more. All this on skimpy news from Citigroup Inc. (NYSE: C) that it may have made a profit in the first two months of the year. That was all it took to get the market to pop!

For it's part, Citigroup jumped even more, ending the day at $1.45, for a $0.40, or 38.10% gain. Sending a memo to employees is not a novel approach to getting some stock buzz when anything more could have ended up being a lawsuit for potentially misleading investors somewhere down the road.

Early this morning, McDonald's (NYSE: MCD) reported February sales, which may act as a lodestone on quarterly earnings. According to MarketWatch, MCD's systemwide sales dropped 4.6%, but "currency fluctuation" caused the problem. Without these fluctuations, MCD's sales would have increased 3.2%.

MCD's same-store sales increased 2.8% in February, or 6.8% excluding a calendar shift for an extra day in February 2008. European sales decreased slightly, but were up 4% taking the calendar shift into account.

Can investing and collecting go hand-in-hand? Yes -- especially if you are collecting coins, stock certificates, bank notes, or other rare items of value.

By 1862, the U.S. government was issuing a lot of paper to finance the Civil War. It was also refusing to redeem the currency in coin. That forced banks to follow suit and citizens soon began hoarding their small change. Day-to-day commerce suffered, until Congress authorized the printing of currency notes with denominations of less than one dollar. People had begun using postage stamps in lieu of coins and that prompted the issuance of notes that carried the images of contemporary stamps of equivalent value. Counterfeiting problems led to more elaborate designs, but the initial issue of "Postage Currency" and four subsequent issues of "Fractional Currency" served Americans well for the next 14 years.

The widespread issuance of U.S. federal paper money began in the early 1860s. For nearly seventy years, most notes measured about 7-3/8 by 3-1/8 inches. That is a little more generous than the economical 6-1/8 by 2-5/8 inch dimensions in use since 1929 and a succinct collector community refers to the two groups as "large-size" and "small-size" notes.

Almost every investor might be counted as a Money Loser of 2008, but anyone who is not living in or invested heavily in Iceland should thank their lucky stars (or anything else they might like to thank). With the global economic situation called as a financial crisis, then I can only assume that the Icelandic meltdown would be a supercrisis or maybe ubercrisis.

Iceland's three largest banks essentially failed in early October of this year, partially as a result of the crisis in U.S. financial markets. As interbank loans were getting tougher and tougher to acquire, Iceland ran into trouble because its banks were too large for the country's central bank to backstop.

From January of 2008 through September, the krona, Iceland's currency, had lost about 35% against the euro. Over the past few years, the U.S. dollar has lost about half of that amount, and it was still a big deal. However, this was just the precursor to Iceland's problems. At that point, it was roughly 130 krona to each euro. By the second week of October, the currency had collapsed and the last trade was at 340 before the government takeover of the banks halted trading. Currently, the system has been stabilized, but it is still 150 krona to each euro.

After the Revolutionary War, paper money issued by the Colonies and the Continental Congress depreciated rapidly in value. Americans lost faith in government currency and for the next eighty years everyday commerce relied heavily on notes issued by a variety of chartered and private banks. Few of these institutions survived into the latter part of the 19th century, but their currencies are actively sought today by an avid collector community. That supports prices year after year and investors are discovering that high grade specimens can be reliable additions to their portfolios.

Consider a pair of notes printed for the New Orleans Canal and Banking Company (ca. 1831-60s). As the scans show, both are in ideal uncirculated condition. The $10 bill features a rendering of a bald eagle. The $1000 note carries a vignette of Prosperity and Liberty seated. Twenty years ago, they sold for $10 and $40, respectively. Two years ago, I bought the specimens pictured for $48 and $160. Earlier this week, I sold them for $70 and $240. The difference in price between the two is a function of rarity. Two to four high grade examples of the $10 note are offered for auction each week. One sees the $1000 note perhaps ten times a year.

"I've long believed that China's currency is due to appreciate notably against the buck," says currency expert Jack Crooks, upon returning from speaking at a Forex seminar in Beijing.

In his World Currency Alert he explains, "Until now, there's been no straight-forward, highly-liquid way to play it. Now there is: the WisdomTree Chinese Yuan Fund (NYSE: CYB)."

"I now think it makes sense to secure some exposure to the Chinese yuan. There's been a major U.S.-China dynamic that's drastically altered the global economic landscape over the last several years. It goes a little something like this:

• China sends goods to the U.S.
• The U.S. sends dollars to China.
• China sends dollars back to U.S.
• The U.S. sends treasuries to China.

"Ultimately, China supplies the globe with liquidity. Behind this capital flow is an artificially undervalued Chinese yuan. This exchange rate situation is why China has become a major supplier of goods and capital to the rest of the world.
