Extreme weather could cause 5 per cent drop in euro zone GDP, bank watchdogs find
The tools aim to help banks and companies understand how climate change may impact their businesses in the short term by testing out a series of climate-related scenarios.
LONDON - Extreme weather events such as heatwaves, flooding and wildfires could wipe as much off euro zone GDP in the next five years as the global financial crisis or the Covid-19 pandemic, a senior European Central Bank official said on July 9.
A series of severe weather-related events could cause an almost 5 per cent near-term drop in euro zone growth, based on the most extreme climate scenario devised by a group of over 140 bank supervisors and regulators earlier this year, according to Livio Stracca, deputy director general at the ECB.
'The peak negative effect on euro area GDP is almost 5 per cent, which is the same order of magnitude as what we have seen in the global financial crisis and a little bit less than Covid-19,' said Dr Stracca, who also chairs the Network for Greening the Financial System's workstream on scenario design and analysis.
The findings are based on a new set of tools designed by the NGFS, a group of central bankers and supervisors working to address climate-risk in the financial sector and economy.
The tools aim to help banks and companies understand how climate change may impact their businesses in the short term by testing out a series of climate-related scenarios.
The group found euro zone growth was most severely impacted in a scenario known as 'Disasters and Policy Stagnation' where heatwaves, droughts and wildfires in 2026 were followed by a combination of floods and storms in 2027.
Should the euro zone follow through with its net-zero transition policies, including its plan for a 55 per cent reduction in greenhouse gas emissions by 2030, it could largely mitigate losses, another scenario found.

Trump tariffs get seal of approval as S&P affirms US credit rating
Singapore - US President Donald Trump's sweeping tariffs have roiled markets, unnerved trade partners and provoked criticism from leading economists. But there is an upside: The levies will help the United States maintain its fiscal health, according to S&P Global Ratings. The credit rating company has affirmed its AA+ long-term rating for the US, in part because it thinks tariff revenues will reduce the fiscal hit of a recent tax and spending bill. It kept the outlook for the long-term rating stable. The decision offers a glimmer of good news for Mr Trump, who has pushed back against arguments that his historic programme of tariffs will damage the US economy. Although the S&P analysts didn't contradict that view, they stressed that as Mr Trump embarks on a bold programme of tax cuts and spending, tariffs will help soften the blow. 'Amid the rise in effective tariff rates, we expect meaningful tariff revenue to generally offset weaker fiscal outcomes that might otherwise be associated with the recent fiscal legislation, which contains both cuts and increases in tax and spending,' wrote analysts in a note. S&P's views matter for investors in the world's biggest bond market, which has been plagued by persistent questions over the fiscal deficit and debt sustainability. Yields on 30-year Treasuries jumped above 5 per cent in May as tariff fears and Mr Trump's multi-trillion dollar tax bill roiled global markets. Buy America Whether tariffs will give the US a meaningful revenue boost is a subject of debate among economists, who point to an apparent contradiction at the heart of Mr Trump's approach: Tariff revenues rely on trade, but Trump has also attempted to pull production back to the US and encourage consumers to buy American-made products – moves that would undercut future levy receipts. So far, the numbers are strong. Tariff revenue reached a fresh monthly record in July, with customs duties climbing to US$28 billion (S$36 billion). US Treasury Secretary Scott Bessent said tariff revenues for all of 2025 could be 'well in excess of 1 per cent of GDP,' revising his previous estimate of US$300 billion. But the bipartisan Congressional Budget Office estimates the recently passed budget bill will add US$3.4 trillion to the deficit over the next 10 years. Top stories Swipe. Select. Stay informed.

That pointed to a muted short-term impact from the S&P report, even if it adds an important voice as traders weigh up the impact of tariffs over the coming months. 'These are still small nuances close to the top of the credit ratings hierarchy and it doesn't signal any material change in the US fiscal health, which is a complex issue,' said Homin Lee, senior macro strategist at Lombard Odier in Singapore. The US lost its last top rating from the big three credit companies in May, when Moody's Ratings lowered the country from Aaa to Aa1. It blamed successive administrations and Congress for swelling budget deficits that it said show little sign of abating. Fitch Ratings and S&P had previously downgraded the US from AAA. S&P said the stable outlook indicates its expectation that while the fiscal deficit won't meaningfully improve, it also won't persistently deteriorate over the next several years. The agency expects net general government debt to surpass 100 per cent of GDP over the next three years, but it thinks the general government deficit will average 6 per cent from 2025 to 2028, down from 7.5 per cent ion 2024. The rating affirmation could be a positive for the US dollar after Trump's tax and spending bill cast doubts on the sustainability of US debt, said Fiona Lim, a senior currency strategist at Malayan Banking. Still, the more lasting driver for the greenback will come from Federal Reserve minutes, as well as Fed chair Jerome Powell's speech in Jackson Hole on Aug 22, she said.

Rich Londoners baulk at hearing ‘no' in efforts to install air-conditioning units
Sign up now: Get ST's newsletters delivered to your inbox LONDON – As Londoners struggle to adapt to rising temperatures, some of the city's wealthier denizens are finding that money cannot always deliver the relief they seek. With temperatures in some parts of the London Underground recently exceeding levels deemed fit for cattle, climate change is well and truly transforming the experience of living in Britain's capital. The response has been a surge in demand for air-conditioning units in high-end homes. Air-conditioning units used to be an infrequent request, says Mr Richard Gill, director at the London-based architecture firm Paul Archer Design. But nowadays roughly 30 per cent of his clients – mostly London's higher earners, including lawyers and finance professionals – want air conditioning. Not all, however, are getting it. That 'no' can be hard to hear for people who are accustomed to plush climate-controlled offices, foreign travel and cars, Mr Gill said in an interview. For Londoners, obstacles to getting a ir-conditionin g units installed in their homes vary. There can be technical or aesthetic restrictions on attaching units to old buildings. And sometimes, councils simply reject claims of overheating. Mr Gill says he had a client living in a 1920s home in Highgate, north London, who had sought permission to install air conditioning back in 2022, which is the first year the UK recorded temperatures over 40 deg C. The council blocked the request because it judged that the house w ould n ot overheat. The client 'would beg to differ,' Mr Gill said. 'Plenty of my clients go, 'I understand Richard, it is a first world problem, but my kids can't sleep and I work long hours'.' Top stories Swipe. Select. Stay informed.

In Camden, a north-London borough that includes wealthy neighborhoods such as Hampstead, Primrose Hill and Belsize Park, a family was denied permission for two air conditioning units earlier in 2025 b ecause of noise and 'visual clutter' concerns, according to public documents reviewed by Bloomberg. The application included images of a thermometer showing evening temperatures exceeding 25 deg C in the home's south-facing bedrooms. The family was suffering from a 'massive issue of overheating within a property which is difficult to cool to safe temperatures,' the report submitted by their planning consultant stated. 'The fundamental issue of this application is not one of comfort, but rather safety for the applicants' children.' Ms Claire Coutinho, the Conservative shadow energy secretary who until 2024 was the politician in charge of the UK's energy policy, has been vocal in her criticism of existing regulations, warning that access to air conditioning was being blocked by 'bureaucrats in ivory towers.' In another case, an application for a rooftop unit submitted to Kensington and Chelsea council last year was denied, after neighbors raised concerns it would be too obtrusive, according to documents reviewed by Bloomberg. Aggregate data on air -condit ioning applications in London was no t made available by city authorities. A spokesperson for Camden Council said that applications for air conditioning are assessed against the borough's development plan, with policies covering sustainability, design and noise all taken into account. A spokesperson for Kensington and Chelsea Council said that there were more restrictions than in other areas because three-quarters of the borough is of special architectural or historic interest. The examples show that climate change can be blind to demographic distinctions, including Britain's famed class divide. The UK, which in recent years has had to deal with recurring sewage leaks into its rivers thanks to the mismanagement of its water utilities, is now struggling to deal with rising temperatures that are affecting all its citizens. Though data on air conditioning remains sparse, a 2022 government estimate indicated that less than 5 per cent of British households have it. Meanwhile, 55 per cent of homes in the UK have bedrooms that are overheating, according to an analysis the same year by Arup, a consultancy. Arup, which conducted its study for the UK's Climate Change Committee, concluded that levels of overheating were even higher in London. Small bedrooms, loft rooms and apartments are particularly vulnerable, it said. A separate study published in June found that indoor overheating reported in UK dwellings soared from 20 per cent in 2011 to 82 per cent in 2022. I t is a trend playing out across Europe, where demand for air conditioning is on the rise. 'We are used to having the heating mindset,' says Dr Simon Pezzutto , a senior researcher at the research center Eurac. 'But now with climate change, we need to switch to the cooling mindset – and most cities in northern Europe are not prepared for that.' The world is on track for more than 3 deg C of warming, according to the United Nations. After 2 deg C, roughly one in five British homes will likely need air conditioning to stay within an acceptable temperature range, according to the Arup analysis. The rest should be able to make do with ceiling fans, reflective paint and shutters, it said. Mr Andy Love, founder of Shade the UK, a community interest company which works with government and authorities to manage overheating risk in buildings, says air conditioning can help keep people safe during periods of extreme heat. But he also encourages homeowners to consider other avenues first. Solutions such as external shutters, rarely used in UK homes, are effective and less expensive to install and to run, he said. 'If we jump straight into an air conditioning country, it's a shame,' Mr Love said. Whatever the solution, there are real dangers to overheated buildings. Overheating at night means poor sleep, which as well as being uncomfortable can lead to long-term health problems like immune system damage and higher risk of heart disease. Not being able to cool down at night also reduces the body's ability to cope with longer periods of heat, increasing the risk of dehydration and heat stress. S ome restrictions in B ritain on installing air-conditioning units are slowly being relaxed. For example, the government this year added air-to-air heat pumps – air conditioning units that can both heat and cool – to a list of building work that can be done without asking for permission. And the government is considering adding air-to-air systems to a subsidy program designed to make heat pumps more accessible, in the interest of helping Britain reach its net zero goals. But limits are still in place. Apartments and buildings deemed valuable for conservation or aesthetic reasons – often expensive dwellings inhabited by high earners – still require special permission. 'Those rules were written for a cooler climate and a dirtier grid,' says Mr Sam Richards, a former government adviser and chief executive of Britain Remade, a campaign group. 'Neither of which exist anymore.' BLOOMBERG

India removes import duty on cotton in temporary relief for garment industry
Sign up now: Get ST's newsletters delivered to your inbox A worker looks for a fabric for dresses inside a store at a garment manufacturing unit in Noida, India, on Aug 7. NEW DELHI - India has exempted import duties on cotton from Aug 19 to Sept 30, fulfilling the demand of industry groups who said exemptions would help make the sector more competitive. The temporary suspension of the duty, announced in a government order late on Aug 18, is seen as a relief for India's garment industry, which is reeling from a steep 50 per cent tariff on shipments to the United States. The US tariff comprises an existing 25 per cent levy and an additional 25 per cent set to take effect later this month, imposed as a penalty for India's purchases of Russian oil. The effective rate compares unfavourably with 20 per cent for Bangladesh and Vietnam, and 30 per cent for China. Industry bodies such as the Confederation of Indian Textile Industry (Citi) had urged the government to scrap the cotton import duty to help make the sector more competitive. Before the exemption, cotton imports were subject to an 11 per cent duty. Industry officials now expect the government to extend duty-free cotton imports beyond September. Reuters earlier reported that some Indian exporters were scrambling to explore manufacturing options overseas to offset the impact of the higher tariffs. Top stories Swipe. Select. Stay informed.

The prospect of exporters relocating production abroad poses a further challenge to the government's 'Make in India' manufacturing drive. India aims to increase textile exports to US$100 billion (S$128 billion) by 2030. The sharp rise in US tariffs comes just as India was emerging as a strong alternative for American garment buyers, with Bangladesh facing political uncertainty and companies seeking to diversify supply chains beyond China.
