Former Treasury Secretary Janet Yellen sharply criticized President Donald Trump’s repeated calls for the Federal Reserve to slash borrowing costs, likening the approach to the fiscal tactics of a “banana republic.”Trump has publicly urged the central bank to deliver the lowest interest rate in the world, arguing that cheaper financing would ease the service burden on the United States’ staggering $39 trillion debt.Speaking at an HSBC investor summit in Hong Kong, Yellen asked, “How often does the president of a developed country demand that interest rates be set to reduce debt‑service costs? This is what you hear in a banana republic.” She warned that such political meddling could unleash inflation if the Fed’s independence is compromised.The Fed, under Chair Jerome Powell, last lowered its policy rate in December to a range of 3.5 %–3.75 %. However, policymakers are growing uneasy about inflationary pressures, especially as the ongoing Iran conflict threatens oil supplies.Powell is slated to step down next month, but his successor—Trump’s nominee Kevin Warsh—has yet to secure Senate confirmation. Powell has indicated he will remain in his role if a replacement is not confirmed, and he may continue as a Fed governor until a pending Department of Justice investigation concludes.Trump has openly dismissed the idea of Powell staying on, telling Fox Business that he would “have to fire him” if the chair does not leave. Powell, for his part, describes the DOJ probe as a “pretext” aimed at pressuring the Fed to cut rates.Warsh, who argues that potential productivity gains from artificial intelligence could justify lower rates, faces skepticism from Yellen, who doubts he commands the same respect as former Fed chair Alan Greenspan. She noted, “Greenspan was widely respected for his expertise; I don’t think Warsh walks in with that level of credibility.”Trump’s broader effort to reshape the Fed board includes an attempt to remove Governor Lisa Cook, who is currently facing a Supreme Court case over alleged mortgage fraud.Meanwhile, finance ministers and central bankers have gathered in Washington for the International Monetary Fund’s spring meetings. Bank of England Governor Andrew Bailey warned that rising oil prices, driven by the Iran conflict, constitute a “major supply shock” that central banks must assess carefully.The IMF has cautioned that a prolonged closure of the Strait of Hormuz could trigger a global recession, underscoring the interconnected risks of geopolitical tensions, sovereign debt, and monetary policy decisions.

Sperm whales produce a series of rapid clicks, known as codas, that researchers have now shown contain vowel‑like elements and phonetic rules akin to those of human speech.Using advanced acoustic analysis and artificial‑intelligence tools, a team led by linguist Gašper Beguš at UC Berkeley found that variations in click length, pitch rise, and fall encode distinct “vowel” sounds, creating patterns comparable to languages such as Mandarin, Latin and Slovenian.The findings, published in the Proceedings B journal, describe the whale communication system as “highly complex” and one of the closest animal parallels to human phonology, indicating a case of independent evolution of language‑like structures.The research was conducted by Project CETI (Cetacean Translation Initiative), which has been recording sperm whales off Dominica. The project recently released video of a collaborative birth, underscoring the species’ rich social lives.According to Project CETI founder David Gruber, the whales’ “chit‑chat” occurs when individuals press their heads together near the surface, a behavior he likens to intimate, face‑to‑face conversation rather than distant shouting.By removing silent gaps between clicks, the team uncovered rhythmic patterns that function like human vowel modulation—altering vocal fold tension to shift an “A” into an “E.” This level of linguistic sophistication surpasses that observed in other vocal animals such as parrots and elephants.Behavioral ecologist Mauricio Cantor (not involved in the study) noted that the discovery reveals multiple interacting layers of structure in whale signals, a complexity previously unappreciated.Project CETI aims to identify at least 20 distinct vocal expressions—covering actions like diving, sleeping, and social bonding—within the next five years, moving toward a functional understanding of cetacean communication.Gruber remains optimistic, comparing current progress to a two‑year‑old child speaking a few words, and hopes that future research will bring the field to a five‑year‑old level of linguistic capability.

The ongoing conflict in Iran has led to a significant increase in oil prices, with the world's top 100 oil and gas companies reaping enormous profits. In the first month of the war, these companies banked more than $30m every hour in unearned profit, according to exclusive analysis for the Guardian. This translates to estimated windfall profits of $23bn for the month of March, with Saudi Aramco, Gazprom, and ExxonMobil among the biggest beneficiaries.The surge in oil prices to an average of $100 (£74) a barrel has resulted in a substantial increase in profits for these companies. If the oil price continues to average $100, the companies are expected to make $234bn by the end of the year. The analysis uses data from a leading intelligence provider, Rystad Energy, analysed by Global Witness.The excess profits come from the pockets of ordinary people as they pay high prices to fill up their vehicles and power their homes, as well as from businesses incurring higher energy bills. Dozens of countries have cut fuel taxes to help struggling consumers, but this has resulted in reduced revenue for public services.Pressure is growing for windfall taxes on the war profits of oil and gas companies, with the European Commission considering a request from the finance ministers of Germany, Spain, Italy, Portugal, and Austria. The ministers argue that this would help ease the burden on the general public and finance temporary relief measures.Aramco is expected to make a war profit of $25.5bn in 2026 if the oil price averages $100. This is on top of the huge profits habitually made by the majority state-owned Saudi company – $250m a day between 2016 to 2023. ExxonMobil, which has a long record of denying climate change, will take in $11bn in unearned war profits in 2026 if the $100 price endures.The impact of the Iran war is likely to be long lasting, with the head of the International Energy Agency, Fatih Birol, describing it as the biggest shock ever to the global energy market. The UN's climate chief, Simon Stiell, warned that fossil fuel dependency is ripping away national security and sovereignty, and replacing it with subservience and rising costs.

Kevin Warsh, a former Federal Reserve governor nominated by President Donald Trump to replace Jerome Powell, has filed ethics disclosures showing personal assets well above $100 million. If confirmed, he would become the wealthiest central‑bank leader in U.S. history. The 69‑page filing, released on Tuesday, lists two private‑fund investments each valued at over $50 million in the Juggernaut Fund LP, plus $10.2 million in consulting fees from the investment office of Wall Street titan Stanley Druckenmiller. Many holdings are described only in broad categories because “pre‑existing confidentiality agreements” prevent full disclosure; Warsh has pledged to divest these assets should his nomination be approved. Federal Reserve ethics rules, tightened in 2022, prohibit officials and their families from owning bank stocks, crypto‑related assets, and impose strict limits on buying and selling securities. The Fed’s own standards, set by the Federal Open Market Committee, are stricter than those governing other federal employees. Beyond the large private‑fund stakes, Warsh’s disclosures reveal a portfolio concentrated in emerging sectors such as artificial intelligence and cryptocurrency. Notable entries include the robotic‑coffee‑bar platform Cafe X, wearable‑tech firm Cionic, an Ethereum layer‑two project dubbed “Blast,” and a reversible male‑contraceptive solution called Contraline. Details for many of these positions are omitted, again citing confidentiality. The filing also enumerates assets held by Warsh’s spouse, Jane Lauder—a member of the Estee Lauder family with an estimated net worth of $1.9 billion. Her holdings feature municipal bonds listed simply as “over $1 million.” Liabilities appear modest in comparison: a 2015 mortgage of up to $5 million with JPMorgan Chase at a 2.75% rate, a revolving credit line of up to $5 million from PNC Bank at roughly 6%, and a $1.95 million capital commitment to THSDFS LLC, an interest Warsh has also pledged to divest. Ethics analyst Heather Jones of the Office of Government Ethics confirmed that Warsh’s divestiture promises would bring him into compliance with the Ethics in Government Act. Nonetheless, the breadth of undisclosed holdings is likely to dominate his upcoming confirmation hearing, scheduled for April 21. Political dynamics add further uncertainty. A key Republican senator has signaled intent to block Warsh’s confirmation until a Department of Justice investigation into Powell’s oversight of Fed‑headquarters renovations concludes. Although a federal judge recently dismissed two subpoenas targeting Powell—citing a perceived attempt to pressure him on interest‑rate policy—the Justice Department plans to appeal, potentially delaying any Senate vote. Powell has indicated he will remain “pro tem” if Warsh is not confirmed by the end of his term on May 15, and he could retain his governor seat until 2028 if he chooses.

Iran has strongly condemned YouTube's decision to ban a pro-Iranian group, Explosive Media, which creates Lego-style artificial intelligence videos. The group was suspended for allegedly posting 'violent content', specifically a video mocking US President Donald Trump and declaring 'Iran won' after a recent ceasefire agreement. The ban has sparked outrage from Iran's Ministry of Foreign Affairs, with spokesman Esmaeil Baghaei accusing YouTube of trying to suppress the truth about the US-Israel war on Iran. Baghaei questioned the ban, highlighting that YouTube hosts content from major animation studios like Pixar, DreamWorks Animation, and The Walt Disney Company. Explosive Media's videos often use US popular culture to portray Trump as isolated and prone to childish tantrums. One video depicted Trump with an oversized yellow head and a flaming backside, holding a sign that read: 'VICTORY! I am a loser'. The group describes itself as independent but is widely suspected of having ties to the Iranian government. The ban has been seen as an attempt to shield the American administration's false narrative from competing voices. Iran's Foreign Ministry has expressed concern that such actions could limit the free flow of information and perspectives on the ongoing conflict.

Brazilian President Luiz Inacio Lula da Silva has requested the extradition of former intelligence chief Alexandre Ramagem from the United States. Ramagem was detained by US Immigration and Customs Enforcement (ICE) in Florida on Tuesday.Lula expressed optimism that Ramagem would be returned to Brazil, stating, "I believe Ramagem will come back to Brazil; he has to come back to serve his sentence."Ramagem fled Brazil in September after being sentenced to 16 years in prison for his involvement in a coup plot in support of former right-wing president Jair Bolsonaro. The plot allegedly included plans to have Lula killed.Brazil has previously requested Ramagem's extradition, and Lula attributed his arrest to his conviction in Brazil. Ramagem also faces allegations of spying on Bolsonaro's political rivals during his tenure as head of Brazil's top intelligence agency, ABIN.Bolsonaro himself is currently serving a 27-year sentence in Brazil for his role in the coup plot. US President Donald Trump previously sanctioned members of the Brazilian judiciary involved in the case and imposed heavy tariffs on Brazil, but relations have since improved.The US and Brazil have recently announced a joint effort to crack down on drug and weapons shipments, marking a new chapter in their bilateral relationship.

Sergey Lavrov touched down in Beijing as Washington intensified its pressure on Iran by attempting to block the Strait of Hormuz, a waterway that carries roughly one‑third of China’s oil imports. The Russian foreign minister was greeted with a red‑carpet reception, according to photos released by Russia’s Ministry of Foreign Affairs. Both Beijing and Moscow condemned the United States and Israel over their involvement in the ongoing war on Iran, noting that the conflict has already strained China’s energy supplies. China, a major purchaser of Iranian crude, denounced a newly announced U.S. plan to prohibit vessels from entering or leaving Iranian ports and coastal waters, calling the measure an unjustified interference with international trade. “The Strait of Hormuz is a vital international trade route for goods and energy, and its security and uninterrupted flow serve the common interest of the global community,” Chinese MFA spokesman Guo Jiakun said on Monday. According to Al Jazeera’s Alan Fisher, the U.S. hopes that by choking Iran’s trade it can force China to pressure Tehran into returning to negotiations, given that Beijing imports about a third of its oil from Iran. Lavrov also held a telephone conversation with Iranian Foreign Minister Abbas Araghchi, emphasizing the need to prevent any resurgence of hostilities in the Middle East and reiterating Russia’s “unwavering readiness” to assist in a diplomatic settlement. Araghchi relayed details of recent U.S.–Iran talks in Pakistan, which ended without a breakthrough, underscoring the limited diplomatic progress on the issue. The visit comes as China‑Russia relations have deepened since Russia’s full‑scale invasion of Ukraine in 2022. Earlier in the week, Chinese Foreign Minister Wang Yi spoke with Lavrov, agreeing that the two capitals would cooperate to de‑escalate tensions in the region. Beijing’s diplomatic calendar this week also featured meetings with Spanish Prime Minister Pedro Sanchez, United Arab Emirates President Mohamed bin Zayed Al Nahyan, and an upcoming visit by Vietnamese President To Lam, highlighting China’s active role in global diplomacy despite its low‑profile stance on the Iran conflict. Analysts note that China’s restrained approach allows it to position itself as a “reliable, stable and predictable partner” for states seeking alternatives to U.S. influence, especially given its extensive trade ties with Tehran. Former U.S. President Donald Trump, slated to visit Beijing next month, warned he would impose a 50 percent tariff on Chinese goods if China provides military assistance to Iran. The claim followed a CNN report citing U.S. intelligence that China might deliver new air‑defence systems to Tehran. Chinese officials dismissed the report as “completely fabricated” and warned of “resolute counter‑measures” should the United States use it as a pretext for additional tariffs.

Asian stock markets experienced a significant surge on Tuesday, while oil prices declined, as renewed hopes for ceasefire talks between the United States and Iran brought relief to global markets. US President Donald Trump announced that Iranian officials had reached out to his administration, expressing their openness to a deal.The positive turn for markets came after Trump's remarks at the White House, where he stated, 'We've been called by the other side, and they would like to make a deal very badly.' This development led to gains in major Asian markets, including Japan's Nikkei 225, which rose as much as 2.5 percent, and South Korea's KOSPI, which gained about 3.7 percent. Singapore's Straits Times Index also climbed about 0.6 percent, while Hong Kong's Hang Seng Index was up about 0.4 percent in the early afternoon, and the SSE Composite Index in Shanghai was about 0.5 percent higher.The rally in Asia followed gains on Wall Street, with the benchmark S&P; 500 finishing up 1 percent overnight. Meanwhile, Brent crude, the benchmark for global oil prices, dipped nearly 1.5 percent, falling below $98 a barrel. This decline in oil prices occurred despite the US imposing a naval blockade on Iranian ports, a move that analysts warn could exacerbate the energy shortage affecting the global economy.Iran has effectively halted shipping through the Strait of Hormuz since the start of the conflict on February 28, significantly impacting the global energy market. Only 21 vessels transited the strait on Sunday, compared to roughly 130 daily transits before the conflict began, according to maritime intelligence provider Windward.
