Neil Wilson, senior market analyst at ETX Capital in London, is anxious about the role technology is playing in the rout. Whether this is a major correction like the one that happened in 2008, or if it's just a healthy, standard correction that happens as a part of normal market cycles, time will certainly tell. He added that as long as the recent rise in bond yields moderates, the bank is confident that market conditions will remain orderly.
The question investors are now asking is whether the worst is over - at least for now. "We're monitoring the stock markets, they are functioning very well and we continue to believe in the long-term impact of the stock markets", Mnuchin said.
That left it not far from last week's low of $1.2335, a break of which could usher in a further correction after its rally to a three-year high of $1.2538 by late last month.
As a result, he thinks that it's entirely possible that this has led to some "complacency", with investors perhaps "getting a little ahead of themselves".
The dollar index last rose 0.13 percent, with the euro up 0.06 percent to $1.2384. Overall, the Dow, which finished 2.3% higher at 24,912.77, swung 1,167 points from its low to its high.

Even before an impressive late-session surge, Wall Street's stronger performance helped the main European stock markets off their worst levels.
After an initial two-per cent drop, major Wall Street indexes recovered but couldn't sustain the rebound, shedding those gains in afternoon trading.
"Many view the [recent] downturn as a necessity to the runaway equity markets and see it as an opportunity for investors to reinvest at more manageable levels", CMC Markets analyst Oriano Lizza said. The Nasdaq climbed 148, or 2.1 percent, to 7,115.
The pan-European FTSEurofirst 300 index lost 2.50 percent and MSCI's gauge of stocks across the globe shed 0.54 percent. These were reinforced by Friday's January US jobs report that prompted worries the Federal Reserve will raise benchmark interest rates at a faster pace than expected this year.
Though many stock indexes are close to where they started the year, the losses mark a reversal of fortune following a sustained period of gains, a pullback that some market pros have been predicting for some time. The Dow Jones industrial average plunged more than 1,100 points Monday.
