Hackers hit Iran's largest cryptocurrency exchange, while global crypto markets tumble after US bombing
At the intersection of geopolitics and cryptocurrency, a sophisticated cyberattack on Iran's financial infrastructure has reverberated through global crypto markets, offering sobering lessons for regulators worldwide.
In what appears to be one of the most politically motivated cryptocurrency heists in history, the pro-Israel hacker group Gonjeshke Darande (Predatory Sparrow) infiltrated Iran's largest crypto exchange, Nobitex, making off with between R1.5-billion and R1.8-billion in bitcoin, ethereum, dogecoin, XRP and solana.
But here's the twist: it wasn't about the money. Instead, the hackers 'burned' the stolen cryptocurrency, permanently removing it from circulation by sending it to inaccessible wallet addresses — a digital equivalent of setting cash on fire.
The attackers used provocative 'vanity addresses' containing explicit anti-terrorist messages, making their political motivations crystal clear.

'Unlike typical hacks for financial gain, the intent here appears to have been politically motivated, aiming to take funds away from the regime,' according to an analysis of the incident.
The same group also claimed responsibility for simultaneously destroying data at Iran's state-owned Bank Sepah, which they accused of funding Iran's military.
The sophistication of these attacks has led security experts to suggest they're beyond the capabilities of typical activist hackers and more in line with nation-state operations.
Iran's crypto curfew response
Iran's central bank responded by imposing strict operating hours on domestic crypto exchanges, limiting them to 10am-8pm daily. This 'crypto curfew' appears designed to prevent capital flight during periods of high geopolitical tension and assert greater control over citizens' cross-border cryptocurrency transactions.
It's not the first time Iran has flexed its regulatory muscles over crypto. In December, the central bank temporarily shut down all exchanges to prevent the national currency, the rial, from depreciating further.
The timing couldn't be worse for Iranian crypto users. Chainalysis notes that Nobitex plays a critical role in Iran's crypto ecosystem, processing more than R200-billion in total inflows, significantly more than the next 10 largest Iranian exchanges combined.
For Iranian users cut off from traditional finance due to international sanctions, it serves as a crucial gateway to global crypto markets.
Lessons for Africa
When national currencies face devaluation due to economic instability or sanctions, cryptocurrencies and stablecoins can serve as stores of value. This is particularly relevant in African countries experiencing high inflation or currency instability.
Unlike traditional financial systems that can be easily shut down or restricted by governments, cryptocurrency networks operate across borders and are more difficult to completely block, though governments can still restrict access to exchanges and on-ramps.
Iran's crypto curfew shows how quickly governments can impose restrictions during crises. This uncertainty can affect market access and asset values.
The key is staying informed about local regulations, using reputable exchanges with strong security practices, and understanding that while cryptocurrency can provide financial flexibility during uncertain times, it's not immune to geopolitical shocks and market volatility.
Global market meltdown
The crypto market's reaction to escalating Middle East tensions has been swift and brutal. Following US airstrikes on Iranian nuclear facilities and President Donald Trump's hints at potential regime change, global cryptocurrency markets shed more than R20-billion in liquidations within 24 hours.
Bitcoin crashed below the six-figure mark for the first time in 45 days. Ethereum plummeted to its lowest price since May, while solana dropped by 8%.
The Block's GMCI30 index, tracking the top 30 cryptocurrencies, slid by nearly 10% over the week, with smaller altcoins faring even worse — small caps plunged by 17% and AI-linked tokens plummeted by 20%.
Perhaps most tellingly, Iran's parliament urged leaders to consider closing the Strait of Hormuz, a crucial artery for global oil shipments. While Iran has never successfully closed the strait, the mere threat rattled markets and highlighted how quickly geopolitical tensions can spill over into financial markets.
The selloff challenges the narrative of bitcoin as a 'safe haven' asset during geopolitical uncertainty. Instead of flocking to crypto, traders opted to cash out, suggesting that fear temporarily outweighed any safe haven appeal.
African lessons in regulatory balance
The Iranian situation offers valuable lessons for African regulators grappling with how to approach cryptocurrency regulation. Sub-Saharan Africa has the world's highest rate of stablecoin adoption at 9.3%, with Nigeria ranking as the world's second-largest adopter of digital assets.
But the Nobitex hack serves as a reminder of the cybersecurity risks associated with centralised exchanges. African countries and exchanges need robust security protocols, regular audits, and clear incident response plans to protect user funds and maintain trust.
Perhaps most importantly, the Iranian situation demonstrates the dangers of regulatory ambiguity. Iran's central bank warnings conflict with the pervasive use of crypto in the country, creating uncertainty that can be exploited by bad actors or lead to poorly designed reactive policies. DM

Growing tensions between Israel and Iran threaten global economic stability
International experts and other experts have raised concerns about the global economic impact of the conflict between Israel and Iran, with the United States joining the conflict by launching airstrikes on three nuclear facilities in Iran over the weekend. The recent escalation of the conflict between Israel and Iran has sent shockwaves through global markets, raising alarms about potential economic repercussions around the world. Over the weekend, the United States launched airstrikes on three Iranian nuclear facilities, further intensifying the already fraught situation. International relations expert, Dr Noluthando Phungula, on Monday said that on a socio-economic aspect, the escalation of conflict is likely to see instability in exchange rates and oil prices. "Sadly this will be felt most in poorer nations. The South African government has been dragging its feet in terms of coming out on its position," she said. "This has been the case with politicians that are often vocal on social media platforms. This makes complete sense considering the recent SA - US disastrous meeting." Malcolm Hartwell, Norton Rose Fulbright director and master mariner, said that recent reports reflected that Iran may attempt to close the Strait of Hormuz in response to the US attack on its nuclear facilities over the weekend. "Approximately 20% of the world's oil passes through the Strait of Hormuz, which means the closure would have an immediate and dramatic effect on oil prices throughout the world," Hartwell said. "It would also have a devastating effect on the economies of the oil-exporting countries surrounding the Arabian Gulf, which rely entirely on the Strait of Hormuz for all of their exports. This includes the UAE, Saudi Arabia, Kuwait, Iraq, and, ironically, Iran." Hartwell said whether Iran was able to close the Strait to civilian tanker traffic remained to be seen, as the US has positioned two of their carrier fleets in that region to respond to any retaliation by Iran. "Whether the conflict escalates or not in the near future, there is no doubt that the threatened closure will impact oil prices, which would have a negative effect on all of the oil-dependent economies and on global trade generally," he said. "The immediate impact on the global logistics sector (outside of the tanker market) would be an increase in fuel prices, which would ultimately be passed onto importers and exporters responsible for 80% of the world's trade. This will ultimately have to be passed onto the producers, manufacturers, and consumers who rely on sea trade." Hartwell added that for those trading to and from the Arabian Gulf, closure of the Strait of Hormuz would have a massively disruptive effect on their operation. "The closure itself would not have an immediate and direct effect on South Africa other than the increase in oil price, shipping costs, and the disruption to import and export driven economies mentioned above," he said. The Strait of Hormuz services only the Arabian Gulf, which means its closure does not have the same effect on maritime traffic around South Africa's coast as we saw with the closure of the Suez Canal, which forced many shipping lines to divert around South Africa.' Annabel Bishop, the chief economist at Investec, said the petrol price increase building for next month in South Africa was around R0.50/litre so far. She said this was due to the lift in the oil price on concerns over supply disruptions in the Middle East to the current $78 per barrel from $67 per barrel two weeks ago. 'A further escalation in the Middle East crisis, which is not unlikely, would see the oil price rise further, and indeed Brent crude is expected to breach the $80 per barrel mark in the near-term on market worries, while the US dollar continues to tick up mildly,' Bishop said. Waldo Krugell, an economist at North West University, said that the closure of the Strait of Hormuz was the key thing for oil supply. "About 20% of global supply goes through there. Scenarios show that could move the price to $90 per barrel," he said. BUSINESS REPORT

Fuel price increases on the cards for July as volatility rocks oil market
Petrol and diesel prices are set to increases from December 4. Petrol and diesel prices are set to go up at the beginning of July. Petrol and diesel are set to become more expensive from the beginning of July. This is thanks to the recent escalation of conflict in the Middle East, following US and Israeli attacks on Iranian nuclear facilities, which has fuelled fears of a wider conflict in the region. Although the latest data from the Central Energy Fund (CEF) shows under-recoveries of between 43 and 46 cents for petrol and 69 to 71 cents for diesel, which would theoretically predict next month's increases, these numbers are based on averages for the month, which are currently growing by the day due to higher international oil prices. Should current oil price trends persist for the coming week, the petrol price increase for July is likely to exceed 60 cents, while diesel could see hikes of more than 80 cents.

Shares rally, oil slumps as Trump announces Iran-Israel ceasefire
Trump says Iran and Israel agree to ceasefire Wall St futures rise, Nikkei up 1.3% Dollar extends pullback, Treasury yields inch up By Wayne Cole and Stella Qiu SYDNEY, June 24 (Reuters) – Global shares rallied and the dollar extended declines on Tuesday after US President Donald Trump said Iran and Israel had agreed to a ceasefire, sending oil prices into a deep dive as concerns over supply disruptions ebbed. Writing on his Truth Social site, Trump implied a ceasefire would go into effect in 12 hours, after which the war would be considered 'ended'. There was no immediate comment yet from Israel. While an Iranian official earlier confirmed that Tehran had agreed to a ceasefire, the country's foreign minister said there would be no cessation of hostilities unless Israel stopped its attacks. Oil prices fell over 3%, having already slid 9% on Monday when Iran made a token retaliation against a US base, which came to nothing and signalled it was done for now. With the immediate threat to the vital Strait of Hormuz shipping lane seemingly over, US crude futures fell another 3.4% to $66.15 per barrel, the lowest since June 11. 'With markets now viewing the escalation risk as over, market attention is likely to shift towards the looming tariff deadline in two weeks time,' said Prashant Newnaha, senior Asia-Pacific rates strategist at TD Securities. 'Our sense is that the quicker than expected resolution to the Middle East conflict leads to expectations for a swifter resolution on tariffs and trade deals.' Risk assets rallied, with S&P 500 futures up 0.6% and Nasdaq futures 0.9% higher. EUROSTOXX 50 futures jumped 1.3% and FTSE futures rose 0.4%. The MSCI's broadest index of Asia-Pacific shares outside Japan jumped 1.8% while Japan's Nikkei rallied 1.4%. Two sources told Reuters that Japan's tariff negotiator Ryosei Akazawa is arranging his seventh visit to the United States for as early as June 26, aiming to end tariffs that are hurting Japan's economy. China's blue chips rose 1%, while Hong Kong's Hang Seng index gained 1.7%. News of the ceasefire saw the dollar extend an overnight retreat and slip 0.3% to 145.70 yen, having come off a six-week high of 148 yen overnight. The euro rose 0.2% to $1.1594 on Tuesday, having gained 0.5% overnight. The yen and euro benefited from the slide in oil prices as both the EU and Japan rely heavily on imports of oil and liquefied natural gas, while the United States is a net exporter. 'The market was so well hedged against a major tail-risk event to play out…the actions and the dialogue we've seen highlight that the tail risks have not and will highly unlikely materialise,' said Chris Weston, head of Research at Pepperstone. Ten-year Treasury yields were 2 basis points higher at 4.35%, having declined 5 bps overnight after Federal Reserve Vice Chair for Supervision Michelle Bowman said the time to cut interest rates was getting nearer as risks to the job market may be on the rise. Fed Chair Jerome Powell will have his own chance to comment when appearing before Congress later on Tuesday and, so far, has been more cautious about a near-term easing. Markets still only imply around a 22% chance the Fed will cut at its next meeting on July 30. The risk-on mood saw gold prices ease 0.6% to $3,346 an ounce.
