据彭博新闻社2023年7月28日报道，全球石油供应趋紧，加上市场预期美联储的紧缩政策即将结束，推动原油价格创下一年多来最长的单周涨幅。
西得克萨斯中质原油(WTI)在7月28日结束当周突破每桶80美元的心理关口，为始于6月底的涨势画上句号，这轮涨势几乎抹去了今年以来的跌幅。推动油价上涨的是欧佩克+的关键国家沙特阿拉伯等限制原油出口，这导致包括渣打银行和瑞银集团在内的银行预测未来几个月全球平衡将趋紧。
现货市场和金融市场都出现了供应紧张的迹象。在过去的四周里，位于俄克拉何马州库欣的美国主要储存中心的库存减少了750万桶，使库存降至5月份以来的最低水平。这支撑了WTI最近两份合约的现货溢价扩大，这种看涨的定价模式已升至去年11月以来的最高水平。
由于股市处于年度高点，更广泛的风险偏好情绪也提振了油价。全球需求前景有所改善，有迹象表明亚洲经济将受到额外刺激，市场猜测美联储的加息已经接近尾声。
尽管油价上涨，但交易商仍在为可能出现的回调做准备，因本周原油在相对强势的情况下多次处于超买区间。由于未平仓合约徘徊在今年1月以来的最低水平附近，油价仍不稳定，容易出现大幅波动。
价格：
纽约9月份交割的西得克萨斯中质原油每桶上涨49美分，报收于每桶80.58美元。本周累计上涨4.6%。
布伦特原油9月份的结算价每桶上涨75美分，至每桶84.99美元。

Oil Posts Fifth Weekly Gain as Global Supply Tightens
Tightening global oil supplies and expectations that the Federal Reserve’s tightening is nearing an end propelled crude to the longest run of weekly gains in more than a year.
West Texas Intermediate broke through the psychological level of $80 a barrel this week, capping a rally that started in late June and has nearly erased this year’s losses. Driving the advance are OPEC+ linchpins Saudi Arabia curbing exports, with Moscow reaffirming its commitment to those obligations this week. That has led banks, including Standard Chartered Plc and UBS Group AG, to forecast tightening global balances in the coming months.
Signs of supply tightness are showing up in both physical and financial markets. Inventories at the key US storage hub in Cushing, Oklahoma, have declined by 7.5 million barrels during the past four weeks, pushing stockpiles to their lowest since May. That’s supporting a widening in the backwardation of WTI’s nearest two contracts, a bullish pricing pattern that has grown to its largest since November.
Prices also have been aided by broader risk-on sentiment, as equity markets are trading at yearly highs. The global outlook for demand improved amid signs of additional stimulus for the Asian economy and speculation that the Federal Reserve’s rate hikes are near or at an end.
Despite the rally, traders are bracing for a potential correction as crude has traded in overbought territory on its relative strength on several occasions this week. Prices remain volatile and prone to large swings as open interest hovers near the lowest levels since January.
Prices:
WTI for September delivery rose 49 cents to settle at $80.58 in New York..It’s up 4.6% for the week.
Brent for September settlement rose 75 cents to settle $84.99 a barrel.
