The US and the eurozone face daunting economic challenges in a world of low inflation and interest rates, and central banks alone do not have the tools to cope.
That was the message delivered to the American Economic Association’s annual meeting on Sunday by former European Central Bank (ECB) president Mario Draghi and former US Federal Reserve chair Janet Yellen.
“I believe that for the euro area there is some risk of Japanification, but it is by no means a foregone conclusion” if it acts comprehensively to avoid a deflationary malaise, Draghi said via a video link to the conference in San Diego, California.
“The euro area still has space to do this, but time is not infinite,” he added.
Yellen, now at the Brookings Institution in Washington, said she agreed with former US secretary of the treasury Lawrence Summers that the US was enmeshed in secular stagnation — a state where desired savings are bigger than investment and interest rates are depressed as a result.
She ticked off a number of structural forces holding down interest rates — including an aging population and sluggish productivity — and suggested that they might be around for a while.
“These factors are apt to prove chronic by nature,” she said.
Draghi took eurozone governments to task for working at cross purposes with the ECB’s efforts to aid the economy in recent years by pursuing restrictive fiscal policies.
“This is why the ECB has been consistently calling for fiscal policy to play a stronger role and capitalize” on the low rates, he said.
He counseled policymakers in Europe against becoming resigned to slipping into deflation.
“It is certainly not too late for the euro area to avoid this,” he said, adding, “The euro area is not in a deflationary trap.”
Yellen said that monetary policy in the US should not be written off as a policy tool to combat recessions just because interest rates are so low.
She agreed with her predecessor, former Fed chair Ben Bernanke, that quantitative easing and forward interest-rate guidance can be effective in providing stimulus to the economy.
However, while “monetary policy has a meaningful role to play, it’s unlikely to be sufficient in the years ahead,” Yellen said. It “should not be the only game in town.”
“We can afford to increase federal spending and cut taxes” to support the economy in a recession even though government debt has risen sharply in recent years, the former policymaker said.
Yellen did, though, express concern about financial stability risks arising out of an extended period of low interest rates.
She also bemoaned the paucity of macro-prudential tools the US has to deal with that.
DECOUPLING? In a sign of deeper US-China technology decoupling, Apple has held initial talks about using Baidu’s generative AI technology in its iPhones, the Wall Street Journal said China has introduced guidelines to phase out US microprocessors from Intel Corp and Advanced Micro Devices Inc (AMD) from government PCs and servers, the Financial Times reported yesterday. The procurement guidance also seeks to sideline Microsoft Corp’s Windows operating system and foreign-made database software in favor of domestic options, the report said. Chinese officials have begun following the guidelines, which were unveiled in December last year, the report said. They order government agencies above the township level to include criteria requiring “safe and reliable” processors and operating systems when making purchases, the newspaper said. The US has been aiming to boost domestic semiconductor
Nvidia Corp earned its US$2.2 trillion market cap by producing artificial intelligence (AI) chips that have become the lifeblood powering the new era of generative AI developers from start-ups to Microsoft Corp, OpenAI and Google parent Alphabet Inc. Almost as important to its hardware is the company’s nearly 20 years’ worth of computer code, which helps make competition with the company nearly impossible. More than 4 million global developers rely on Nvidia’s CUDA software platform to build AI and other apps. Now a coalition of tech companies that includes Qualcomm Inc, Google and Intel Corp plans to loosen Nvidia’s chokehold by going
ENERGY IMPACT: The electricity rate hike is expected to add about NT$4 billion to TSMC’s electricity bill a year and cut its annual earnings per share by about NT$0.154 Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) has left its long-term gross margin target unchanged despite the government deciding on Friday to raise electricity rates. One of the heaviest power consuming manufacturers in Taiwan, TSMC said it always respects the government’s energy policy and would continue to operate its fabs by making efforts in energy conservation. The chipmaker said it has left a long-term goal of more than 53 percent in gross margin unchanged. The Ministry of Economic Affairs concluded a power rate evaluation meeting on Friday, announcing electricity tariffs would go up by 11 percent on average to about NT$3.4518 per kilowatt-hour (kWh)
OPENING ADDRESS: The CEO is to give a speech on the future of high-performance computing and artificial intelligence at the trade show’s opening on June 3, TAITRA said Advanced Micro Devices Inc (AMD) chairperson and chief executive officer Lisa Su (蘇姿丰) is to deliver the opening keynote speech at Computex Taipei this year, the event’s organizer said in a statement yesterday. Su is to give a speech on the future of high-performance computing (HPC) in the artificial intelligence (AI) era to open Computex, one of the world’s largest computer and technology trade events, at 9:30am on June 3, the Taiwan External Trade Development Council (TAITRA) said. Su is to explore how AMD and the company’s strategic technology partners are pushing the limits of AI and HPC, from data centers to
