Last month, the collapse of Silicon Valley Bank, the second-largest bank failure in US history, unleashed broader panic and raised fears the global financial system would seize up. Now, central banks are signaling that their immediate concerns have eased.

The Bank of England, the Bank of Japan, the European Central Bank and the Swiss National Bank said Tuesday that they would end daily measures to boost the flow of US dollars to lenders around the world. They cited “improvements in US dollar funding conditions” and “low demand” at recent operations aimed at providing liquidity.

Starting May 1, those operations will once again be held weekly, a decision made in consultation with the US Federal Reserve, the primary source of dollars. The frequency could increase again if needed, the four central banks said.

“These central banks stand ready to readjust the provision of US dollar liquidity as warranted by market conditions,” they said in their statements.

Policymakers sprung into action in March after the collapse of Silicon Valley Bank and Signature Bank in the United States sparked an acute bout of turmoil in the global banking sector. The tumult also nearly took down Credit Suisse (CS), a globally important but troubled bank, forcing Swiss authorities to arrange an emergency sale to rival UBS (UBS).

Hours after the Credit Suisse takeover was announced, the Fed said it would work with central banks in the United Kingdom, Japan, Canada, Switzerland and the European Union to make sure lenders there had access to the dollar liquidity they needed.

That meant making greater use of dollar swap lines, or agreements between the Fed and other central banks to provide dollars in exchange for, say, euros or yen.

Swap lines are a key instrument in central banks’ toolbox aimed at preserving financial stability and keeping credit flowing to households and businesses.

It is still morning when Kinzaburo Shiga, 77, returns to Onahama port after catching a trawler full of fish off Japan’s eastern coast.

But the third-generation fisherman won’t head straight to market. First, he’ll test his catch for radiation.

It’s a ritual he’s repeated for more than a decade since a devastating earthquake and tsunami triggered a nuclear meltdown at the Fukushima Daiichi power plant in 2011, spewing deadly radioactive particles into the surrounding area.

Radiation from the damaged nuclear plant leaked into the sea, prompting authorities to suspend fishing operations off the coast of three prefectures that had previously provided Japan with half of its catch.

That ban lasted over a year, and even after it was lifted, Fukushima-based fishermen like Shiga were for years mostly limited to collecting samples for radioactivity tests on behalf of the state-owned electricity firm Tokyo Electric Power Company, or TEPCO, rather than taking their catches to market.

Ocean currents have since dispersed the contaminated water enough that radioactive cesium is nearly undetectable in fish from Fukushima prefecture. Japan lifted its last remaining restrictions on fish from the area in 2021, and most countries have eased import restrictions.

Shiga and others in the industry thought they’d put the nightmare of the past years behind them.

So when Japan followed through on plans to gradually release more than 1 million metric tons of filtered wastewater into the Pacific Ocean from the summer of 2023 – an action the government says is necessary to decommission the plant safely – the industry reeled.

The Japanese government and the International Atomic Energy Agency (IAEA), a United Nations body promoting the peaceful use of nuclear energy, say the controlled release, which is expected to take decades, will meet international safety regulations and not harm the environment, as the water will be treated to remove radioactive elements – with the exception of tritium – and diluted more than 100 times.

But with the deadline for the planned water release looming this summer, Fukushima’s fishermen fear that – whether the release is safe or not – the move will undermine consumer confidence in their catches and once again threaten the way of life they have fought so hard to recover.

Whether a major corporation decides to call a country home depends on factors like trade and tax policies, the global economy and political and business shifts in power. Today, with many businesses more mobile than ever, a country’s ability to draw firms to its soil can seriously impact its overall standing in the world.

A companion to the overall 2022 Best Countries rankings from U.S. News, the 2022 Best Countries to Headquarter a Corporation rankings are drawn from a global survey of more than 17,000 people and highlight countries based on their perception among approximately 4,500 respondents considered “business decision-makers.

senior leaders in an organization or small-business owners who employ others. The list is based on respondents’ association of various countries with nine particular country attributes: connected to the rest of the world, corrupt, economically stable, educated population, favorable tax environment, is a place I would live, safe, well-developed legal framework and well-developed infrastructure.
