Markets were calm Sunday as tensions continue to flare between the United States and North Korea and the investigation into President Trump's campaign's potential collusion with Russia hits a new stage.

The yen rose 0.06% against the dollar Sunday evening, while the Canadian dollar was up 0.05% relative to its U.S. counterpart. Meanwhile, the dollar rose 0.03% against the euro, 0.02% against the pound and 0.09% against the Australian dollar. Major U.S. indices were flat Sunday, with the Dow Jones Industrial Average, S&P 500, and Nasdaq each adding single digits.

On Saturday, the UN Security Council unanimously passed a resolution sanctioning North Korea for its repeated ballistic missile tests. Resolution 2371 bans exports from North Korea including coal, iron, seafood and lead; freezes some assets on North Korean individuals and entities; and caps the number of work permits UN member states can issue to North Korean citizens.

"It's time for North Korea to realize we're not playing anymore," U.S. ambassador to the UN Nikki Haley told Fox News.

United Nations Resolution is the single largest economic sanctions package ever on North Korea. Over one billion dollars in cost to N.K.

Notwithstanding geopolitical tensions, the currency moves follow the dollar's rally Friday after better-than-expected July nonfarm payrolls and the possibility of a significant cut to the U.S. corporate tax rate.

According to the Bureau of Labor Statistics' monthly nonfarm payrolls, the United States added 209,000 jobs in July, ahead of the expected 180,000 well above the average of 179,000 a month since Donald Trump took office, but short of last year's average of 187,000. Average hourly earnings rose 0.3%, in line with expectations. The labor force participation rate ticked up to 62.9% from 62.8%.

The jobs beat was led by hospitality, which added 62,000 jobs in July. The embattled retail sector managed to add 900 jobs, while the manufacturing sector, which Trump has championed, added 16,000 jobs.

Despite the president's and the Republican-controlled Congress' inability to pass a healthcare bill, Gary Cohn, Trump's chief economic adviser and rumored pick to replace Janet Yellen as Federal Reserve chair, hit the airwaves last week saying that the White House is ready and able to pass a massive tax-reform bill, including lowering the corporate rate to below 23%.

It's another busy week for corporate earnings, kicking things off with Tyson Foods Inc. (TSN) , CBS Corp. (CBS) and Marriott International Inc. (MAR) on Monday, followed by CVS Health Corp. (CVS) , Michael Kors Holdings Ltd. (KORS) , Valeant Pharmaceuticals International Inc. (VRX) and Walt Disney Co. (DIS) on Tuesday.

However, uncertainty about Trump's ability to deliver on his legislative agenda, such as tax reform, is weighing on markets. And special counsel Robert Mueller's investigation into possible collusion between the Trump campaign and the Russian government is also stymieing the president's agenda. The Wall Street Journal dropped a bombshell on Thursday, reporting that Mueller impaneled a grand jury in Washington to investigate the collusion. The New York Times added the next day that Mueller has asked the White House for the first time to hand over records as part of his investigation.
