(Reuters) -Right now, it's all about deadlines, as lawmakers race to thrash out a deal on the U.S. borrowing limit, time runs short for Russia and Ukraine to agree on how to keep grain exports flowing and Turkish voters count the days to a second round of voting.
Here's a look at the week ahead in markets from Kevin Buckland in Tokyo, Lewis Krauskopf in New York and Amanda Cooper, Naomi Rovnick and Karin Strohecker in London.
1/ HOGGING THE G7 SPOTLIGHT
U.S. Treasury Secretary Janet Yellen told Reuters on Saturday she was "hopeful" there would be a solution to the impasse over the government's debt ceiling.
But as world leaders prepare to meet at a G7 summit in Japan for discussions on everything from the climate to the war in Ukraine, many may be distracted by the question of how a potentially disastrous U.S. default can be averted.
With bipartisan divides running deep, President Joe Biden has hinted he may not even make it to Hiroshima at the weekend.
That would complicate a reported side summit with Japan and South Korea on strengthening security cooperation. Host nation Japan has more at stake than many in this standoff: It is the largest foreign holder of U.S. debt.
2/ ERDOGAN AND THE ECONOMY
In a surprisingly strong showing, President Tayyip Erdogan led comfortably in the first round of Turkey's election with his rival now facing an uphill struggle to prevent him extending his rule into a third decade in a runoff vote on May 28.
The presidential vote will decide not only who leads Turkey and shapes the foreign policy of the NATO-member country of 85 million people, but also how it is governed and its economic future amid a deep cost-of-living crisis.
Turkish bonds, stocks and the lira weakened on Monday as Erdogan's momentum doused hopes that the country could pivot in the near future to a more orthodox monetary and economic policy.
With Turks facing a sharp decline in living standards and an economy that is battered by crippling inflation and a collapsing lira, the challenges for whoever ends up at the helm of Turkey will be enormous.
3/ GOING AGAINST THE GRAIN
Russia and Ukraine have until May 18 to extend the Black Sea grain deal, which last year allowed the safe passage of Ukrainian exports to help tackle a global food crisis.
The two sides could extend the agreement, but Russia says it will walk unless its demands to remove obstacles to its own exports are met. The two are among the world's biggest exporters and supply some of the poorest countries.
Ukraine said on Monday no more talks had been scheduled this week.
