NEW YORK, June 12 (Reuters) - World stock markets were little changed on Tuesday while the U.S. dollar fell slightly against an index of major currencies, as investors brushed aside a long-awaited U.S.-North Korea summit aimed at denuclearizing the Korean peninsula.
U.S. President Donald Trump and North Korean leader Kim Jong Un met in Singapore, pledging to work toward complete denuclearization, while Washington committed to providing security guarantees for its old enemy.
The MSCI all-country world index, which tracks shares in 47 countries, gained 0.07 percent on the day.
The dollar index fell 0.04 percent, steadied in part by data on Tuesday showing U.S. consumer prices rose in May amid a slowdown in the increase of gasoline costs.
The euro was up 0.06 percent to $1.1789.
Investors had mixed reactions to the North Korea summit, which ended with the signing of a joint statement that gave few details on how the goals set by both sides would be achieved.
"Any de-escalation is good, because in the background you always have worries about these situations," said Old Mutual Global Investors European fund manager Ian Ormiston.
Others felt the sit-down between Trump and Kim did little to change the game.
"Markets are skeptical," said Brad McMillan, chief investment officer for Commonwealth Financial in Waltham, Massachusetts. "This is more of a case of 'we'll believe it when we see it', rather than actually reacting."
Buyers of equities and government bonds seemed more interested in other matters. Along with the positive U.S. inflation data, investors were focused on the kick-off of a two-day U.S. Federal Reserve meeting, at which the Fed is expected to raise interest rates, as well as meetings later this week by the European Central Bank and the Bank of Japan.
“"We’re eagerly awaiting the Fed, the ECB and the BOJ, in that order," said Gregory Anderson, global head of FX strategy at BMO Capital Markets in New York. "People are reluctant to do a whole lot ahead of that."
Futures contracts indicate a 96 percent probability the fed funds rate will be raised a quarter of a percentage point on Wednesday, according to CME Group.

Wall Street's main equity indexes were mixed but steady, with the Dow Jones Industrial Average falling 8.78 points, or 0.03 percent, to 25,313.53, the S&P 500 gaining 3.07 points, or 0.11 percent, to 2,785.07 and the Nasdaq Composite adding 28.74 points, or 0.38 percent, to 7,688.66.
Twitter drove the jump on the benchmark S&P, gaining 6.25 percent in midday trading after J.P. Morgan raised its price target by $11 to $50.
