As worries about deflation rear their ugly head in Europe, investors are debating whether the European Central Bank will act to prop up the continent's economy.
The euro has weakened against the dollar lately as some currency traders bet that concerns about low inflation will prompt the ECB to announce more stimulus on Thursday. The ECB already has its key interest rate near zero.
Others weren't so sure.
"The ECB is more likely to talk than act," said Societe Generale's Kit Juckes.
Data Monday showed that the annual rate of inflation in Europe fell to 0.5%, down from 0.7% in February. Inflation is now at its lowest level since November 2009.
There are clearly some headwinds for the European economy, and plenty of people are hanging on to every word ECB chief Mario Draghi says.
Last week Draghi said the ECB remained committed to fighting deflation. Foreign exchange traders took that as a sign that the ECB could unveil plans for more economic stimulus. And low inflation data from Germany and Spain last week also fueled the stimulus speculation.
That talk has been playing out in the currency market. One euro is currently trading at around $1.38, down from just under $1.40 in the middle of March. That may not sound like a significant difference. But it is in the world of currencies.
Further monetary easing, or so the theory goes, would drive down the euro and therefore boost exports as the cost of production cheapens. At the same time, inflation should pick up as more money is pumped into the financial system.
But whether the ECB will actually announce new stimulus is anyone's guess.
"A weaker euro is desirable now," said Marc Chandler, a foreign exchange analyst with Brown Brothers Harriman. He added that despite the recent drop, the euro is still relatively strong compared to other currencies. The mid-March peak against the dollar was the strongest it's been since October 2011.
But Andrew Milligan of Standard Life Investments doesn't think the ECB will make any big policy announcements Thursday. Rather, he said Draghi may have been trying to talk the euro down without having to take action. He feels Draghi was assuring the market that he has the tools combat deflation, even if he doesn't plan to use them yet.
"The deflation threat is high at this point in time," Milligan said.
But words alone might not be enough, according to Milligan. While verbal intervention can mitigate fears about deflation temporarily, Draghi's statements ultimately won't have any impact without actual intervention in the currency markets, he said.
Even worse, stimulus at this point could send the wrong message to countries that haven't taken concrete steps to mend their finances.
While Germany and Spain have made structural reforms, France and Italy still have more work to do. Launching more stimulus now would be a reward for bad behavior, Milligan said.
The euro's dip contrasts with a strengthening dollar. While Europe is talking about the possibility of its central bank aiding the economy, the Federal Reserve is continuing to wind down its stimulus as the economic picture in the United States brightens.
If the ECB decides not to act, Chandler predicts the euro will rise sharply again.

Investors drove up prices for Spanish bonds Friday, forcing yields to their lowest level since May, on hopes the European Central Bank will soon intervene in the market.
The yield on Spain's 10-year bond fell to a low of 5.68%, dropping below the key 6% threshold for the first time in over three months. Italian bond yields also fell sharply, hitting a low near 5%.

European Central Bank President Mario Draghi defended the euro currency Wednesday and reiterated that "exceptional measures" are justified to stabilize financial markets.
In an op-ed published in German newsweekly Die Zeit, Draghi said the euro was launched as a "currency without a state," built on an "institutional framework" that left it vulnerable to crises.
Draghi went on to say that the the euro area needs a "new architecture" to complete the monetary MOREBen Rooney - Aug 29, 2012 12:55 PM ET
Spain and Italy have been a major source of concern for global investors, but you wouldn't know it from the stock markets in those countries.
Monday was a down day for most European markets, but stocks have been rising across the continent since European Central Bank president Mario Draghi made his now-infamous remark that the ECB will do "whatever it takes to preserve the euro" late last month.
Since Draghi uttered those MOREBen Rooney - Aug 20, 2012 12:44 PM ET

After the Federal Reserve declined to spike the punchbowl Wednesday, fans of monetary stimulus are now entirely dependent on the European Central Bank for a fix.
In leaving its policies unchanged, the Fed gave investors what they expected, but not what they wanted. Now, all eyes are turning to Frankfurt, where top ECB officials will meet Thursday for their monthly policy discussion.

Super Mario to the rescue! European Central Bank president Mario Draghi said Friday that Europe's central banks stand ready to "continue to supply liquidity to solvent banks where needed."
Speaking at an ECB conference in Frankfurt, Draghi said strengthening European economic growth is a critical issue that needs to be addressed sooner rather than later.
"There is a long-standing agenda on growth" he said, adding that "it is time to implement it MORECatherine Tymkiw - Jun 15, 2012 8:23 AM ET
Spanish 10-year bond yields have officially pulled a Kenny Loggins and ridden into the 7% danger zone. Italian bond yields are north of 6% again and climbing. And oh yeah, Greek elections on Sunday may lead to the end of a Hellenic presence in the euro and a return to the drachma. The crisis is far from over.
