Oil rose, helped by positive news about vaccine trials and an EU stimulus deal, taking prices to levels last seen when an oil price war erupted in early March between Russia and Saudi Arabia.
Benchmark Brent crude was up $1.24 cents at $44.52 by 1337 GMT, on track for its biggest daily rise since mid-June at around 3%. West Texas Intermediate (WTI) gained $1.26 to reach $42.07, its highest daily rise this month at around 3.1%.
Prices were buoyed by an agreement among European Union leaders on a 750 billion euro ($859 billion) fund to prop up their coronavirus-hit economies, lifting prospects for fuel demand.
In other financial markets, world shares and the euro also hit their highest in several months. The dollar, in which most oil contracts are priced, fell to its lowest since March against a basket of currencies.
The EU deal allows the European Commission to raise billions of euros on capital markets on behalf of all 27 states, an unprecedented act of solidarity in almost seven decades of European integration.
Oil prices were also supported by promising coronavirus vaccine data released on Monday, raising confidence that a vaccine may be created even if a global rollout will take time.
