Crude oil pulled back from its highest levels in roughly a week on Wednesday after a weekly read on crude inventories showed a smaller-than-expected decline. The Energy Information Administration reported a 2.5-million-barrel decline in stocks, weaker than an expected drop of 3.25 million barrels.
The International Energy Agency warned in its monthly report that ballooning inventories could threaten the "recent stability of prices." Output in the Middle East has risen, while production in the U.S. has shrunk, creating a short-term balance in supply.
West Texas Intermediate crude oil fell 2.3% to $45.72 a barrel on Wednesday.

The outcome of the Brexit vote has increased uncertainty over the U.S. economic outlook, Cleveland Fed President Loretta Mester said on Tuesday. Mester also noted the Fed has the ability to pause before determining the next interest-rate move.
"I do not think U.S. monetary policy is behind the curve yet" so it was right for the Fed to hold rates steady in June, Mester said in a speech on the economic outlook at the Australian Business Economists Luncheon in Sydney. "I expect we will be living with uncertainty for a while as the U.K. and Europe establish the terms of their new relationship."
The chances of a rate hike this year have been greatly diminished by recent rough patches in economic data and the uncertainty surrounding the United Kingdom's exit from the European Union. However, a stronger-than-expected U.S. jobs report in June reintroduced the possibility of a rate hike later in 2016.
