According to the report, Gaza's economy contracted by 6 percent in the first quarter of 2018. It said unemployment is now over 50 percent — and over 70 percent among Gaza's youth.
The World Bank cited various factors, starting with Israel's decade-long blockade against the territory's Hamas rulers, for the precarious downturn. It also cited budget cuts by the rival Palestinian Authority and a reduction in international aid to the Palestinians, particularly from the United States.
"A combination of war, isolation, and internal rivalries has left Gaza in a crippling economic state and exacerbated the human distress," said Marina Wes, the World Bank's director for the region.
The report was released ahead of a high-level meeting of the bank's Ad Hoc Liaison Committee, responsible for coordinating development assistance to the Palestinians, on Sept. 27.
Wes said the increasingly dire economic situation in Gaza "has reached a critical point."
"Increased frustration is feeding into the increased tensions which have already started spilling over into unrest and set back the human development of the region's large youth population," she added.
Gazans have staged near weekly demonstrations along the border with Israel since late March, in part to protest the blockade enforced by Israel and Egypt since 2007, when the Palestinian group Hamas took control of the territory. Protest turnout has also been driven by growing despair over blockade-linked hardship, including lengthy power cuts and soaring unemployment.
Israeli soldiers have killed at least 136 Palestinians during the weekly protests since March, including 27 minors, according to Gaza's Health Ministry.
On Monday evening, at least one Palestinian was killed and 10 others wounded by Israeli soldiers, the Palestinian Health Ministry said. In a statement, the ministry said Fayez Abu al-Sadiq, 21, was killed by Israeli gunfire in the northern Gaza Strip.
Human rights groups have accused Israel of excessive and unlawful use of force against unarmed protesters.
Gaza's economic situation is likely to deteriorate further because of failed attempts to negotiate an easing of the blockade. Hamas leaders said this week that Egypt-mediated efforts to broker a long-term cease-fire with Israel have stalled.
Repeated attempts to broker a reconciliation deal between rival Palestinian factions — Hamas and President Mahmoud Abbas's Fatah party — have also failed.
In the report, the World Bank calls upon Israel to lift restrictions on trade and movement of goods and people to help improve Gaza's economy, and urges development of "legitimate institutions to govern Gaza in a transparent and efficient manner."
