Investing.com – Crude prices clinched a second straight week of gains on Friday as money continued to slosh into commodity markets, lifting prices of almost everything, from oil to and  — even .

Since February began, price screens for Nymex, Comex, and CBOT — the exchanges for energy, metals, and agriculture — have been flashing green in unison almost every day, like pinball machines on a winning streak. 

While each market is driven by its own fundamentals, the one common thing buoying them all, like the proverbial tide that lifts all boats, is the flow of cheap, easy funds looking for sexy returns as U.S. rate hikes look doomed for now and the Federal Reserve keeps printing money to stimulate recovery from the Covid-19. President Joe Biden also has a $1.9 trillion coronavirus relief plan seeking Congressional approval.

“Economic scarring will warrant easy money for a lot longer,” said Ed Moya, a senior market strategist at OANDA in New York. 

“Crude prices continue to rally as optimism overflows. Given the strength heading into a long weekend, it seems energy traders are hesitant on scaling back,” he said, referring to Monday’s President’s Day holiday in the United States. 

New York-traded crude was up 4.6% for the week, settling at $59.47 per barrel. It earlier hit a session peak of $59.81, its highest since January 2020. Last week, WTI rose nearly 9%.

London-traded , the global benchmark for crude, gained 5.2% on the week, settling at $62.43. Brent hit a 13-month high of $62.83 earlier on Friday. Last week, it rose 6%.

Oil’s marathon rally over the past two months has been sparked and sustained by a combination of factors. It began with the November breakthrough in vaccines for the Covid-19, followed up by OPEC leader Saudi Arabia’s announcement of deeper production cuts in January; commodity-index linked buying of oil, sizable weekly drops in U.S. crude stockpiles and hopes for economic stimulus from the Biden administration. 

Many analysts, as well as industry executives from Vitol and Gunvor, had expressed caution over the rally.

Technical chartists repeatedly referred to the breach of the Relative Strength Index metric for WTI, which was at its most overbought level since the second Iraq war in 2003.

Mike Muller, the Asian head for Vitol, the world’s largest independent oil trader, said at the weekend that the market was “getting ahead of itself in terms of a post-vaccine euphoria.”  

Torbjorn Tornqvist, chief executive at Gunvor, another large independent oil trader, expressed concern that crude prices sustained at beyond $60 a barrel might trigger an avalanche of shuttered supply that would ultimately suppress the market.

Others noted that while U.S. had fallen sharply over the past four weeks, spurring the oil rally, much of that has turned up as lacking immediate consumption as the pandemic continued to limit driving and mobility.

But some analysts, including Phil Flynn at Chicago’s Price Futures Group, expect the rally to continue. “This has been a story of OPEC cuts balancing the market and the sense of a new oil supercycle as (industry) investment is being shut down due to a global green energy push,” said Flynn.
