More than four million Syrians have been displaced as a result of the ongoing crisis and the brunt of resettling them has fallen to Lebanon, Jordan, Turkey.
World Bank officials say they will to talk to shareholders about financially supporting surrounding regions, while other countries have also increased their humanitarian efforts.
The escalating violence in Syria has had profound and ongoing impacts on its citizens.
Four million people have been displaced as a result, with Syrians fleeing to neighbouring Turkey, Iraq, Lebanon, Egypt and scattering across Europe.
As international affairs expert Dr Wesley Widmaier explains, it's proven to be a major financial strain on those countries.
"They're spending between one and two per cent of GDP on dealing with the refugee crisis. That may not sound like a lot, but America spends three per cent of its GDP on defence. So it's a pretty big commitment and it's a pretty big shock to the system."
To alleviate that shock, the World Bank says it plans to try to compensate countries for the costs incurred.
Senior Adviser to the World Bank President, Colin Bruce, told European Union leaders in Geneva it is the appropriate response.
"We recognise that for many of these countries there is a cost associated with hosting refugees and so they need to be compensated and we are quite prepared to enter into that dialogue with our shareholders as to how we support the compensation of countries, and in particular the middle-income countries that often do not have access to concessional resources, and that's the conversation that is taking place."
Humanitarian officials have previously criticised the World Bank's policies which forbid it from making grants to middle-income countries.
That leaves a large funding gap.
Turkey has also complained that it is only receiving a fraction of the billions of euros it is spending to host its large Syrian intake.
Colin Bruce says the plan significantly helps those struggling nations.
"It's actually quite significant for countries like Jordan, for Lebanon and for Turkey, and some estimates put that at about 1.1-1.4 per cent of GDP, that's a cost in the short term."
Dr Widmaier says the World Bank's decision marks a return to its core mission.
"The underlying value is it's got to help countries in times of crisis. So the fact that they're changing their rules to lend today to middle-income countries who they're not supposed to lend to, it's not a change in their values to the extent that this is the largest refugee crisis since the 1940s. It's perfectly in tune with what the World Bank is about - to lend funds today to help rebuild, especially in a time and a context where private capital may not be willing. So the World Bank has a kind of special legitimacy and image."
Those developments come as China offers more aid across Africa and the Middle East to help reduce the flow of refugees from the source.
Foreign Ministry spokeswoman Hua Chunying says China will accelerate its efforts.
"In consideration of the current severe refugee issue, especially when the chilly winter is coming, China will accelerate to fulfil the humanitarian aid, that has been announced, to relevant countries in west Asia and north Africa within this year, and will continue to supply more humanitarian aid to the region and the countries, in a bid to help Middle East countries enhance their abilities to host and settle refugees."
Qatar has also announced it will be sending aid to Syrian refugees in Croatia, while last month Japan tripled its aid to address the crisis.
With more than 100 million people requiring humanitarian support around the world, the United Nations wants to reform funding models worldwide.
The UN has said on several occasions refugees and migrants are likely to have a positive economic impact in the long term on the countries they're resettled.
