The dollar rose to a two-week high on Monday against a basket of currencies, lifted by rising geopolitical risk over Ukraine and a likely hawkish stance from the Federal Reserve at its policy meeting this week.
Markets until recently had mostly shrugged off the massing of Russian troops on Ukraine's borders, but tensions have ratcheted up lately. NATO said it was putting forces on standby and reinforcing eastern Europe with more ships and fighter jets, in what Russia denounced as an escalation of tensions.
The United States is considering transferring some troops stationed in western Europe to eastern Europe in coming weeks, a NATO diplomat told Reuters, and U.S. President Joe Biden ordered diplomats' families to leave Kyiv.
"Given people have lost money, whether it's in crypto or the stock market, people want to find a culprit and I think that people are torn between two possible candidates: the Federal Reserve and Russia," said Marc Chandler, chief market strategist at Bannockburn Global Forex.
"I’m skeptical that all of this is Russia driven," Chandler said, referring to the sell-off in equity markets. "But it doesn't mean when the first shots are fired, there won't be a dramatic market reaction."
ING Bank strategist Francesco Pesole said markets were pricing more of a risk premium into the euro, with fears increasing that Russia's stand-off over Ukraine with the West could prompt Moscow to curb energy supplies to Europe.

The dollar index has gained some 1.5% since Jan. 14. During this period, several banks have raised forecasts for the speed and size of the Fed's policy tightening, a picture that should be clearer at the end of its two-day meeting on Wednesday.
The Fed is expected to signal the start of interest rate hikes in March, while potentially indicating how fast it will shrink its holdings of Treasuries and mortgage debt that have swollen its balance sheet past $8 trillion.
Most expect the first hike to be 0.25% in March and three more to 1.0% by year-end. FEDWATCH .
Data showed on Friday speculators cut net long positioning on the dollar to the lowest since September and instead added a net $2.6 billion of euro positions.
Leaving aside Ukraine tensions, the dollar's recovery could stall if the Fed signaled a preference for balance sheet reduction as a means to tighten policy, Pesole said.
"If markets see the Fed willing to let balance sheet reduction do the heavy lifting, that may force a scaleback in forecasts for the number of rate hikes," he said.
"The dollar will find more support from actual rate hike expectations than expectations of draining liquidity out of the market."
