World leaders will be in New York next week
According to Bloomberg's Jennifer Jacobs, the schedule so far includes:
South Korea's Moon
Egypt's Sisi
France's Macron
Israel's Netanyahu
Japan's Abe
UK's May
More will be added but the biggest risk I see is Abe. Trump has been hinting lately that he may turn his trade ire to Japan and with Abe's election out of the way, now might be the time.
In the bigger picture, expect plenty of talk about some of the big geopolitical issues next week, including Iran, North Korea, the Middle East, nuclear weapons and some of the other usual suspects.
