A problem that originated in the New World is re-exposing some long-standing nuanced opinions in the Old World.

France and Germany disagreed over how to prevent the global credit crunch from further hurting European banks. Germany, Europe's largest economy, does not want to set up a bailout / rescue fund that France is seeking. Luxembourg Prime Minister Jean-Claude Junker said the fund, which France argued should be as large as 300 billion euros or about $415 billion, isn't needed.

Economist Richard Felson said the United Kingdom also is against the idea, with Britain arguing that an ad hoc intervention policy would be sufficient for now. "A lot will depend on how the U.S. rescue package, provide it passes the U.S. House, performs in lowering overnight interest rates and restoring confidence," Felson said. "There's the sense in the U.K. that while the crisis extends beyond America's borders, the bulk of the bad-asset fallout will still be U.S.-based."

The U.S. Senate passed a revised rescue package, 74-25, Wednesday night and the U.S. House is expected to vote on the measure as soon as Friday.

However, the measure had little impact on overnight interest rates, at least initially. The London Interbank Overnight Rate, or LIBOR, rose for a fourth day, up 6 basis points to 4.21% Wednesday night, as banks continued to hoard cash.

These days, the U.S. Federal Reserve is not getting a great deal of help from its companion major central banks regarding monetary policy stimulus to pull the global economy out of is pronounced slowdown.

In the case of the Bank of England, it kept interest rates the same despite anemic GDP growth. In the case of the European Central Bank, it kept it's key rate at a seven-year high.

Economist: Two terrible decisions

Today, the BOE kept its benchmark interest rate at 5%, the ECB did the same at 4.25%, and London-based economist Mark Chandler is happy with neither.

"Just two terrible decisions stemming from flawed reasoning. Just dreadful," Chandler said. "The BOE and ECB are putting too much responsibility on the Fed to stimulate demand when we need all three central bank engines pulling at once to get out of this economic rut."

The comeback of the beleaguered dollar continues.

The dollar strengthened to a six-month high versus the euro Tuesday, and also rose against the world's other major currencies on a growing consensus in foreign exchange circles that global economic fundamentals are shifting in favor of the greenback.

The dollar strengthened about 1.5 cents to $1.4465 versus the euro, and about 1.4 cents to $1.7877 versus the British pound Tuesday at mid-day. The buck also gained one-half yen to 108.62 versus Japan's yen.

Pivotal for dollar: Europe, Asia GDP

Further, although Tuesday's dollar catalyst was the realization that Hurricane Gustav would cause considerably less-than-forecast damage to Southeast U.S. oil production and the refinery infrastructure, trader Andrew Resnick told BloggingStocks the longer-term focus remains regional GDP growth.

"With Hurricane Gustav out of the way, sentiment's building that this dollar rally has legs. European growth has slowed to recession levels, and China's economy has slowed as well. For Europe, lower interest rates are likely to follow, and that's dollar bullish," Resnick said. Resnick added that he expects the Bank of England to cut its benchmark interest rate by a quarter-point to 4.75% when it meets September 4. He doesn't expect the European Central Bank to lower its 4.25% refinance rate on September 4, but that stand-pat policy may change to accommodation, later this fall.

There are lines of reasoning, and then there are lines of reasoning.

European Central Bank board member Axel Weber said Wednesday there's no plan for interest rate cuts and policy makers may, in fact, have to raise rates as the economy accelerates out its slump, Bloomberg News reported. He added that "monetary policy is where it should be" and that "discussion about declining rates in Europe is premature."

Weber's comments occur after Eurostat reported that Europe's economy contracted 0.2% in the second quarter (pdf), amid signs of slowing in business investment and consumer spending, and sagging business confidence.

London-based economist Mark Chandler told BloggingStocks Wednesday that data he's reviewed indicate Europe's economy will continue to slow in Q3, which is why he's somewhat taken aback by Weber's comments.

"Weber's comments are a bit troubling. I mean, what data is he looking at? The comments will create a bit of a row [dispute] in the U.K. because our economy is not going to contribute to the recovery he sees, not at this stage," Chandler said.

Some market signals are well-known and easily understood. Others are arcane and more-complex, but just as telling.

There's mounting evidence that the "carry trade" is ending, or that at least institutional investors are decreasing their use of it as an investment tactic.

In a carry trade, investors, especially institutional investors, borrow funds in a country with a low interest rate (or borrowing cost) and buy assets in a country where returns are higher. The investment can take many forms, including stocks, bonds, funds, or even the higher-interest currency itself.

Carry trade: A growth confidence indicator

Now, investors/readers may legitimately ask, Why is it important to know what's happening to the carry trade?

Economist Peter Dawson told BloggingStocks that it's important to monitor carry trade flows and data because it's one indicator of investor confidence in a market's ability to produce a return on equity, and by extension, in its economy to grow.

In other words, the carry trade abounds when investors are confident; it wanes when they're not, he said.

One way investors/readers could characterize the current environment is as a world filled with concerns.

Concern about the U.S. housing sector. Concern about declining U.S. disposable income. Concerning about slowing GDP growth in Europe and Asia. Concern about the Yankees not winning the American League pennant.

O.K., that last item was a purely subjective, parochial one, but you get the point: there's concern that global economic conditions are worsening, not improving.

Europe's GDP is latest focal point

Further, while emerging markets in Asia, led by China and India, have been the growth story of the decade, the region really sending a chill up economists' -- business executives' -- spines is Europe, so says economist Glen Langan.

"Up through July we had seen weakness in Italy, Greece, Spain, and Portugal, and the investment community's response was one of 'no big deal, they are not the major growth regions, anyway,'" Langan said. "But now there's signs of slowing in Germany, France, and the United Kingdom, and nearly every demand-side indicator is in retreat. It's a pronounced psychological shift, no question."

The dollar Friday was on course to record its fifth consecutive weekly gain, propelled higher by the prospect that economies in Europe may be later in the recession/expansion economic cycle than the United States.

The above suggests the Bank of England and the European Central Bank will have to cut interest rates -- itself a bullish factor for the dollar -- with the U.S. economy recovering sooner than the economies in the United Kingdom and euro-zone -- another dollar-bullish circumstance.

On Friday, the dollar strengthened 1.5 cents to $1.4675 versus the euro, and about seven-tenths of a cent to $1.8632 versus the British pound. The dollar also rose about 1 yen to 110.61 versus Japan's yen and about one-half cent to $1.0988 versus the Swiss franc.

From dollar-bear to dollar-skeptic

Currency Trader Andrew Resnick said he's not a dollar bull yet, but the changing global economic landscape has moved him from the dollar-bear category to "the dollar-skeptic category."

"Clearly, fundamentals are shifting in favor of the dollar. Global growth is slowing, taking pressure off commodity prices. Export gains are lowering the U.S. trade deficit, and there's now a better than 60% chance Europe [including the U.K.] will have to cut interest rates," Resnick said. "Those are the best fundamentals for the dollar in about three years." Resnick added that he's presently flat, or had no open currency trading positions.

Europe's economy contracted in Q2 for the first time since the euro was launched more than 10 years ago, as exports underperformed and energy costs cut into consumers' disposable income, Eurostat, the European Union's statistics office announced (PDF) Thursday.

Euro-zone Q2 GDP fell 0.2% and EU27 Q2 GDP -- which includes nations in the European Union but not formally a part of the euro currency system -- fell 0.1%, Eurostat said. In Q1, Euro-zone GDP rose 0.7%.

Further, on a year-over-year basis, euro-zone GDP increased 1.5%, with inflation running at about 4.0%, well above the European Central Bank's 2.0% annual limit.

Economist: 'Bad news for global economy'

Economist David H. Wang told BloggingStocks Thursday Europe's slowing economy "is bad news for the global economy."

"This is bad news because we need European growth to prevent a global economic slowing. But the economies in two major European economies are clearly slowing. Germany's GDP fell 0.5% in the first quarter, and France's fell 0.3% in the second quarter, so given their make-up in the euro-zone, Europe has experienced a pronounced slowing," Wang said.

Confidence in the global economy rose in August as oil prices retreated, a new survey of business professionals indicated. The Bloomberg Professional Global Confidence Index climbed to 14.1 in August from 10.3 in July. The July reading was the lowest since the survey began in November 2007. Readings below 50 indicate negative sentiment.

Economist Glen Langan, who did not participate in the Bloomberg survey of about 3,000 Bloomberg Terminal users, said investors / traders "should not attach too much positive sentiment to results."

"First, the survey was at an all-time low in July. Second, we have seen a $30 drop in oil prices, so I would sense that there would be some relief expressed in surveys of financial professionals, executives, and the like," Langan said. "Economic conditions, particularly in the U.S., are sluggish to poor, and the survey generally reflects that."

Oil traded up 80 cents to $113.81 early Wednesday, but has dropped about $34 since hitting a record high of $147.27 on July 11, 2008.

Focus on U.K., E.U.

Langan said the focal point for economists is now the United Kingdom and the European Union. For example, in his projections, Langan has already discounted that the U.S. economy will remain sluggish through at least Q2 2009, but he still sees 1.5-1.9% GDP growth in the United Kingdom, and 2.0% GDP growth in the E.U. for 2009.

Typically, markets conform to historical tendencies. But sometimes they don't. Tuesday was one example of the latter regarding the dollar in the currency market.

Despite a two-week-long move that saw the dollar strengthen against the world's major currencies, the greenback's rally continued early Tuesday, as lower commodity prices reduced their appeal as an inflation hedge and an investment. Oil, the world's most important commodity, fell $1.16 to $113.42 per barrel early Tuesday.

The dollar rose about one-quarter cent to $1.4875 versus the euro and about 1 cent to $1.9022 versus the British pound in Tuesday trading.

The dollar has strengthened about 6% versus the euro and about 4.5% versus the British pound in the past two weeks, and London-based economist Mark Chandler told BloggingStocks Tuesday further strengthening against the pound is likely, after a correction.

Dollar overbought, but rising

"The dollar should have corrected by now, given that it's registered a remarkable move and it's over-bought short-term, but markets can overdo it from time to time, so who knows when the correction will occur," Chandler said. "But longer-term I see further dollar gains against the pound, due to our [United Kingdom's] slowing economy."

The much-maligned, beleaguered dollar -- driven lower for nearly a decade by series of unconscionable mistakes by United States' policy makers, may be poised to make a comeback.

But don't try to put those words into the mouth of currency trader Andrew Resnick. No sir. Dollar what? Resnick remains the skeptic of skeptics. There have been too many false break-outs and weak rallies that proved to be mere corrections in the euro's decade-long rise, in Resnick's view, to conclude at this juncture that the worst for the dollar -- and, by extension, for the United States -- is over.

A strong week for the greenback

That said, the week's data points are compelling. The dollar registered its biggest gain in two months against the euro, strengthening to $1.5006 -- or an improvement of almost 3.7% -- an enormous move in the currency market for one week. The dollar also strengthened about 2.1% versus the British pound to $1.9208, and about 2% versus Japan's yen to 110.08 yen.

What has caused the sudden turn of events in the currency market? (We don't want to use more-positive adjectives just yet.) Not the health of the U.S. economy, according to Resnick.

Interest rates remain on hold across the pond.

The European Central Bank and the Bank of England kept benchmark, short-term interest rates the same Thursday, as the major central banks chose to take a wait-and-see stance amid the competing challenges of rising inflation and slowing growth.

The ECB kept its key rate, the refinance rate, at 4.25%; the BOE, its rate on commercial bank reserves, at 5%.

The euro and British pound were little changed versus the dollar after the decision. The euro strengthened about three-tenths of a cent to $1.541 and the British pound strengthened one-quarter cent to $1.9516 in Thursday afternoon trading in Europe.

Rates: tougher call for BOE

London-based economist Mark Chandler told BloggingStocks Thursday the Bank of England's circumstance is "a tougher call for monetary policy markers" than the ECB's.

"In the U.K., inflation is rising and the growth outlook is not good, whereas [continental] Europe has a better GDP outlook. So in that sense the Bank of England has a difficult task, similar to the U.S. Federal Reserve's. They have to find a way to bring down inflation from about 4% to 2% without causing a deeper contraction," Chandler said. "Given slowing growth right now, the best stance was to do nothing." The BOE has cut interest rates three times since December 2007.

If the leading ECB official is correct, the West is about witness yet another episode of 'That 70s Inflation Show'.

European Central Bank President Jean-Claude Trichet warned Wednesday that euro nations are already seeing the first signs of a wage-price inflation spiral, and called on governments to exercise discipline by not granting wage hikes that could further fan inflation via consequent price rises, The Associated Press reported.

The ECB's governing council "is strongly concerned that price and wage-setting behavior could add to inflationary pressures," Trichet told the European Parliament, while also defending the ECB's decision last Thursday to increase interest rates. "First signs are already emerging in some regions of the euro area."

A wage-price spiral typically occurs when employees and others seek wage increases to keep pace with rising prices. The increased wages ratchet up employer costs, who pass the added costs on to consumers via higher prices, perpetuating the wage-price spiral.

Trichet's concern: Rising European inflation

"It's like that wave approaching the shoreline that you see in the distance and don't think is big, and then it's 100 feet in front of you and you realize it is."

That's how London-based economist Mark Chandler described Europe's perspective on the potential 'latest wave' of the housing crisis -- the research report by Lehman Brothers (NYSE: LEH) that Fannie Mae (NYSE: FNM) and Freddie Mac (NYSE: FRE) may have to raise up to $46 billion and $29 billion in additional capital, Bloomberg News reported.

Europe is concerned that the pair's announcement "signals another round of write-downs here in England and Europe as well as in America" Chandler told BloggingStocks Tuesday, with negative consequences for the stock market, and, equally significant, for business and consumer confidence, he said.

Europe's major stock markets decline

Indeed, Europe's major stock markets did not react favorably Tuesday to the Lehman report. London's FTSE fell 66.70 points to 5446.00, Germany's DAX declined 104.49.35 to 6,291.71, and France's CAC 40 fell 78.22 to 4,263.37 in Tuesday afternoon trading.

The European Central Bank's quarter point interest rate increase has been called 'counter-productive,' 'unnecessary,' even 'self-defeating.'

All of which begs the question, why did the ECB last Thursday increase interest rates so soon? (The ECB increased its key interest rate, the refinance rate, a quarter point to 4.25%, last Thursday.)

One argument is euro zone inflation, presently running at about a 3.7% annualized rate. That's well above the ECB's 2% inflation limit.
