EghtesadOnline: The dollar wallowed near a six-week low against the safe-haven yen on Wednesday, with traders cautious ahead of Britain's general election, a European Central Bank policy decision and testimony by former FBI Director James Comey.
The greenback treaded water at 109.490 yen, not far from 109.225, its lowest since April 21 plumbed overnight, according to Reuters.
The dollar has lost 0.9 percent against the yen this week, also pressured by a sharp drop in U.S. Treasury yields to seven-month lows as investors sought the safety of government debt.
The U.S. currency was seen coming under more pressure as previously bullish equities also began declining. Wall Street shares pulled away from recent record highs and fell overnight as demand for risky assets waned ahead of Thursday's events.
"The dollar has felt the tug of lower U.S. yields for a while now, but buoyant stocks had helped neutralise some of that pressure," said Junichi Ishikawa, senior FX strategist at IG Securities in Tokyo.
"But it lost even that support, and the dollar's fall gathered momentum."
Comey, who will testify on Thursday, was investigating whether Donald Trump's presidential campaign and Russia colluded to sway the 2016 U.S. election when he was fired by Trump in May. Investors are worried his testimony could dampen already flagging momentum for Trump's agenda of rolling back regulations and overhauling the tax code.

The common currency was still shy of the seven-month high of $1.1285 touched on Friday as a wait-and-see mood prevailed ahead of the European Central Bank's policy meeting on Thursday, another of this week's major events that the markets are bracing for.
While the ECB is not expected to shift rates or make changes to its quantitative easing scheme this week, market participants will sift through President Mario Draghi's statements for his view on the euro zone economy.
Tempering expectations for the ECB to start planning an exit from is easy policy, Draghi said last week that while euro zone growth may be improving, inflation remains subdued and still requires substantial stimulus.
"Of the three big events on 'Super Thursday,' the ECB meeting could be the least disruptive as participants have already had time to curtail their previously hawkish expectations," said Ayako Sera, senior market economist at Sumitomo Mitsui Trust.
"The remaining two, however, are political events. The markets are at their current levels because these events are simply difficult to read."
