Investors will hope Kevin Warsh offers ‘comfort blanket’ at annual meeting of central banks amid bond market anxiety

The new US Federal Reserve chair, Kevin Warsh, faces a critical test this week amid anxiety in government bond markets over inflation and Donald Trump’s tax and spending plans.

Abbas Araghchi says country is unbowed but president Masoud Pezeshkian admits its people face ‘many problems’

Iran’s foreign minister has dismissed the threat of a fresh round of US economic sanctions as a “desperate” ploy, even as its president acknowledged that the Iranian people are facing “many problems” amid Washington’s efforts to isolate and debilitate the country’s economy.

Last week, Donald Trump announced a new campaign to increase the pressure on the Iranian economy, calling it “the most crushing economic operation ever taken against any country”. The US Treasury secretary, Scott Bessent, is expected to announce further punitive economic measures on Iran – which he has described as “the toughest sanctions in history” – on Monday.

As the president tries to extract the US from his Iran war quagmire, leadership in Tehran is only too happy to crush his midterm dreams

In the aftermath of his devastating election defeat, the US president remained haunted by regrets over Iran.

Months before Jimmy Carter lost the 1980 presidential election to Ronald Reagan, eight US servicemen died in a botched high-risk rescue mission that failed to secure the freedom of dozens of US hostages seized in Tehran.

President at rally in South Carolina makes comments on key strategic waterway and jokes about bombing Iran

Donald Trump called the strait of Hormuz “an American territory” on Friday, as the US continues its military blockade of Iran’s shipping and ports while Trump’s administration struggles to end its war with the country.

“We don’t even know if we won, because I view the strait of Hormuz as an American territory right now,” Trump said, addressing a crowd in South Carolina. He was campaigning for senator Darline Graham, who is running to permanently fill her late brother Lindsey Graham’s Senate seat.

State sought to stop system off coast of Santa Barbara from resuming operations after Trump ordered its reopening

An oil pipeline can continue to operate off the California coast after a judge gave it the green light this week, despite the opposition of state regulators and environmental groups.

The system off the coast of Santa Barbara resumed operations earlier this year for the first time in more than a decade after Donald Trump ordered Sable Offshore Corporation to reopen it, citing US energy needs during the war in Iran.

USS George Washington will replace warship families say suffers from shortages, plumbing problems and low morale

The USS George Washington aircraft carrier has arrived in the Middle East, where it is expected to relieve the USS Abraham Lincoln from its record deployment amid concerns about poor living conditions and morale.

US Central Command announced on Thursday that the Washington arrived in the area on Wednesday, and posted an image of sailors working on the flight deck as the ship transited the Arabian Sea. No date has yet been announced for the Lincoln to return to the US.

Despite previously comparing him to a ‘mobster’, Trump’s former personal lawyer showers him with praise. This blog is now closed.

An FBI team seized electronic devices from former US representative Eric Swalwell at the San Francisco airport on Saturday, then raided his home in Washington, DC, the next day, CNN reported Thursday.

The raid is part of a federal investigation into the sexual assault allegations which ultimately drove the Bay Area Democrat to resign from office in April, sources familiar with the investigation told CNN. The Manhattan District Attorney’s Office and the Los Angeles Sheriff’s Department subsequently opened criminal investigations on Swalwell.

On one side, you face the domination of the Islamic Republic; on the other, the imperialist forces that republic claims to stand against

August marks the anniversary of the 1988 mass executions in Iran, a horror that echoes in the country’s current surge in death sentences. It also marks the 19 August anniversary of the UK- and US-orchestrated coup against the prime minister Mohammad Mosaddegh in 1953. Amid the current, indiscriminate waves of US-Israeli military assaults against Iran, this letter of solidarity denounces the repression of the Iranian people and their political prisoners by forces both at home and abroad.

Interest rates, now sitting at about 3.5-3.7%, expected to go up if inflation doesn’t come down to Fed’s 2% target

The US treasury is doubling its buyback of government debt in an effort to balance out the bond market as officials at the US Federal Reserve remain divided over how to deal with high inflation.

The yield rate on 10-year, 20-year and 30-year treasury notes all hit 20-year highs this week, with the 30-year treasury yield rising to its highest rate since 2007. The rapid rise was concerning news for borrowers as major loans, including mortgages, are backed by treasuries.

Brent crude rises above $90 a barrel for the first time since 30 July after US president tells Tehran to surrender

Oil prices have risen again after the two-month window to negotiate a peace deal in the US-Israel war on Iran expired on Monday with no end to the conflict in sight.

Iran said on Monday that it would take a more aggressive stance if talks with the US failed, while Donald Trump demanded Tehran “put up the white flag of surrender” in an interview with Fox News.

USS Benfold lost power after ‘engineering casualty’ leaving sailors without galley services, toilets and air conditioning

A US guided-missile destroyer reportedly spent four days adrift and without power in the South China Sea in July, furthering concerns about strain being placed on deployed military members.

The USS Benfold, an Arleigh Burke-class guided-missile destroyer which had been sailing with the George Washington carrier strike group, was reported to have been towed to Subic Bay in the Philippines, according to the US Naval Institute News, an independent military publication.

Energy prices have been high since the US-Israel war with Iran began and the strait of Hormuz was blocked

US gas prices this month are so far the highest ever recorded for August as peace talks between the US and Iran have stalled and Donald Trump launched fresh threats against Oman.

The national average price of gas was $4.06 per gallon on Monday, according to data from AAA, $0.05 higher than last week and $1 more expensive than a year ago. In California and Hawaii, averages hit about $5.50 a gallon.

The president was forced to hide in a catering truck amid the Iran war, in an encapsulation of the conflict’s failures

For decades, Donald Trump cultivated a public image based on strength and dominance. He was a brash New York real estate mogul; a reality TV star who deployed his signature phrase: “You’re fired!” to eliminate contestants from The Apprentice; and eventually US president and undisputed leader of the Republican party.

In recent months, Trump has taken his boastfulness to an extreme, reportedly telling confidants that he’s “the most powerful person to ever live” and comparing himself with some of history’s most feared leaders, including Genghis Khan, Napoleon, Hitler, Stalin and Mao.

Senator Ruben Gallego calls carrier’s months-long deployment a ‘deep problem’ as wellbeing concerns mount

Democrats on Sunday intensified their demands for answers from the Trump administration over conditions onboard the USS Abraham Lincoln as the aircraft carrier’s nearly nine-month deployment continued fueling concern over crew morale, mental health and living conditions.

Ruben Gallego, a Democratic senator from Arizona, said on Sunday that problems onboard the Lincoln had kept mounting – and he blamed the carrier’s prolonged deployment on the unresolved war that Donald Trump started in February with Iran as well as lackluster leadership in general from the Republican president’s administration.

One US sailor’s mother asks: ‘My son signed up to serve his country. But why isn’t his country serving him?’

Naval families with loved ones deployed for months on US warships amid the Iran war have reacted with fury to Donald Trump and the defense secretary Pete Hegseth’s dismissal of their concerns about the extreme pressures and dire conditions they are enduring.

The Guardian has talked to three naval families who have been following the physical and mental stresses bearing down on their relatives with mounting alarm. The families, with loved ones on board the USS Abraham Lincoln and USS Tripoli, all spoke anonymously for fear of retribution against their active duty relatives.

‘Complete unraveling’ of Trump and Republican project reflects attitude of not caring at all about governance

He was always one step ahead. Donald Trump won the US presidency as a wildly unlikely outsider in 2016 and staged an astonishing comeback to win it again in 2024. Even his foes grudgingly called him a political savant with an intuition for exploiting grievances that left so-called experts floundering.

But now they are asking if the dark genius has lost his touch. Trump is trapped in the quagmire of an unpopular war, obsessing over monuments in Washington and looking for a new spokesperson after his White House press secretary quit. If the 80-year-old was deliberately trying to sabotage his Republican party in November’s midterm elections, it is not clear what he would do differently.

Prolonged deployment is coupled with reports of water shortages, plumbing issues and attempts to jump overboard

• Trump downplays concerns about sailors onboard USS Abraham Lincoln

US navy veterans and military health experts are expressing concerns about the strain on sailors aboard the USS Abraham Lincoln, which has spent nearly nine months at sea supporting US operations in the Middle East, amid reports of poor living conditions and worsening mental health among its crew.

The San Diego-based aircraft carrier left port on 21 November, originally bound for the Pacific, but was redirected to the Middle East as the US-Israel war with Iran began. It has now spent more than 250 consecutive days at sea without a significant port visit, with its deployment repeatedly extended.
