Oil prices dropped to a 12-week low in volatile trade on Wednesday, extending Tuesday's heavy losses as growing fears of demand destruction from a global recession outweighed supply concerns.

Brent LCOc1 futures for September delivery fell $2.99, or 2.9%, to $99.78 a barrel by 10:57 a.m. EDT (1457 GMT), while U.S. West Texas Intermediate (WTI) crude fell $3.19, or 3.2%, to $96.31.

That puts WTI and Brent on track for their lowest closes since April 11, after Brent fell 9% and WTI fell 8% on Tuesday.

It also put both benchmarks in technically oversold territory with a relative strength index (RSI) below 30 for a second day in a row. If Brent closes at that level, it would be the first time it remains in oversold territory for two days since December 2021.

Investment bank Goldman Sachs said the oil sell-off was driven by growing recession fears.

Germany's government borrowing costs fell to a five-week low as mounting concern about a darkening economic outlook drove investors into safe-haven debt.

U.S. stock indexes slipped on Wednesday as investors awaited minutes from the Federal Reserve's meeting to gauge the health of the economy and the pace of interest rate hikes to stamp out spiking inflation.

Oil prices were also knocked down by a soaring U.S. dollar.DXY, which rose to a near 20-year high against a basket of other currencies.

A stronger U.S. dollar makes oil more expensive for holders of other currencies, which can curb demand.
