Sweden’s Riksbank urges households to keep cash and multiple payment options for crisis preparedness

Sweden’s central bank, the Riksbank, is urging households to strengthen their ability to make everyday payments in the event of disruptions, warning that the current international situation, combined with Sweden’s high level of digitalisation, may expose vulnerabilities in the national payments system.

The bank frames the advice as part of national preparedness, describing the public as a key component of ‘total defence’ of Sweden and stressing that resilience in the payments market is essential during temporary outages, wider crises and, in the worst case, war.

The Riksbank’s main message is that households should avoid relying on a single way to pay and instead ensure they can use several methods, including cash, cards and mobile payment services. As a benchmark, it recommends keeping SEK 1,000 in cash per adult at home to cover about a week of essential purchases, while noting that some households may need more or less depending on size and circumstances.

Where possible, it advises keeping cash in multiple denominations and encourages people to use cash occasionally in normal times to help keep the cash system functioning.

For card payments, the bank recommends having access to at least two cards from different card networks, such as Visa and Mastercard, so that if one network is disrupted, another may still work. It also highlights mobile payment services such as Swish, noting that they rely on a different infrastructure from card payments and may still function even when cards do not.

People who mainly use mobile wallets like Apple Pay or Google Pay are advised to keep physical cards and PINs readily available in case a phone runs out of battery or fails; the bank adds that a physical card’s chip may allow offline payments during interruptions.

Power hardware shortages are delaying AI data centre expansion, despite record investment

US AI data-centre expansion is increasingly being constrained not by chips, servers or funding, but by the electrical hardware needed to connect new facilities to reliable power, Bloomberg reports. While the US–China trade war has pushed many server makers to move production out of China, the deeper dependency remains in power-delivery equipment.

China is still the world’s largest producer of electrical gear used to build and upgrade power infrastructure, both inside data centres and across the wider grid. Shortages of key components, especially transformers, switchgear and batteries, sourced from China and elsewhere, are now slowing project timelines.

The scale of planned build-outs is colliding with these supply limits. Bloomberg cites forecasts that Alphabet, Amazon, Meta and Microsoft will spend more than $650bn in 2026 to expand AI capacity, yet close to half of the planned US data-centre builds this year are expected to be delayed or cancelled.

The problem extends beyond the data-centre fence line. Companies must also fund and coordinate grid upgrades to supply enough electricity, competing for the same scarce equipment as utilities coping with rising demand from electric vehicles and electrified heating.

Sightline Climate data cited by Bloomberg suggests about 12GW of US data-centre capacity is expected to come online in 2026, but only around a third of that capacity is currently under active construction due to multiple constraints. Electrical infrastructure may represent less than 10% of total data-centre cost, but it is schedule-critical, because delays in any link of the power chain can halt an entire project.

Lead times for high-power transformers, in particular, have deteriorated sharply, typically 24 to 30 months before 2020, but now stretching to as long as five years, clashing with AI deployment cycles that can be under 18 months.

To cope, developers are turning to global suppliers, with Canada, Mexico and South Korea becoming major sources of high-power transformers. Even so, US imports of Chinese high-power transformers have surged from fewer than 1,500 units in 2022 to more than 8,000 units through October 2025, according to Wood Mackenzie data cited by Bloomberg. China also supplies over 40% of US battery imports and remains near 30% in some transformer and switchgear categories, underscoring continued reliance despite tariffs and security concerns.

Why does it matter?

Bloomberg’s central warning is that without easing bottlenecks in transformers, switchgear and batteries, and expanding US manufacturing capacity, trillions of dollars of AI investment may not translate into delivered AI capacity, because power infrastructure, not compute, is becoming the limiting factor.

ENISA launches consultation on EU digital wallet certification

The European Union Agency for Cybersecurity (ENISA) has launched a public consultation on a draft candidate certification scheme for the EU Digital Identity (EUDI) Wallets.

The draft was developed with a dedicated ad hoc working group, and the consultation aims to gather feedback on its structure, core elements, and annexes. Responses are open until 30 April 2026.

The initiative follows the adoption of a regulation establishing the European Digital Identity Framework. The European Commission has mandated ENISA to support the certification of EUDI Wallets, including the development of a European cybersecurity certification scheme under the Cybersecurity Act.

The objective is to define cybersecurity requirements for digital identity solutions and support their consistent implementation across the EU.

In February 2026, ENISA signed a €1.6 million contribution agreement with the European Commission for two years to support the development and rollout of national certification schemes.

Funded under the Digital Europe Work Programme 2025–2027, the agreement supports capacity development, skills development, and alignment with a future European certification framework. Member states are expected to provide at least one certified EUDI Wallet by the end of 2026.

Digital identity wallets are intended to enable secure identification and the protection of personal data in both digital and physical environments.

The proposed certification scheme aims to verify compliance with cybersecurity requirements, addressing the limited use of formal certification in current wallet implementations.

The initiative carries significant regulatory weight as it translates the European Digital Identity Framework into enforceable cybersecurity standards. It ensures harmonised compliance across member states while strengthening trust, interoperability, and legal certainty within the EU’s digital identity ecosystem.

New quantum threat could weaken cryptocurrency encryption systems

A new warning from Google says advances in quantum computing could weaken widely used cryptographic systems protecting cryptocurrencies and digital infrastructure. A new whitepaper suggests future quantum machines may need fewer resources than previously estimated to break elliptic curve cryptography.

The research focuses on the elliptic curve discrete logarithm problem, which underpins much of today’s blockchain security. Findings suggest quantum algorithms like Shor’s could run with fewer qubits and gates, increasing concerns about cryptographic resilience.

To address the risk, the paper recommends a transition to post-quantum cryptography, which is designed to resist quantum attacks. It also outlines short-term blockchain measures, including avoiding reuse of vulnerable wallet addresses and preparing digital asset migration strategies.

Google also introduced a responsible disclosure approach using zero-knowledge proofs to communicate vulnerabilities without exposing exploitable details.

The company says this balances transparency and security, supporting coordinated efforts across crypto and research communities to prepare for quantum threats.
