Rand firms as oil retreats, but Russian refinery strikes threaten fresh fuel-price volatility

South Africa's rand strengthened against the US dollar on Thursday while the Johannesburg Stock Exchange recovered from Wednesday's losses, even as renewed Ukrainian drone attacks on Russian oil infrastructure threatened to prolong volatility in international petroleum markets.

Brent crude, the international oil benchmark, fell towards $104 a barrel during morning trading, offering some relief to oil-importing economies despite continued uncertainty surrounding the wars in Ukraine and the Middle East.

The rand traded at R16.5575 against the dollar at 8.38am South African time, approximately 0.3% stronger than its previous close, as the US currency retreated from an 18-month high.

The rand's recovery followed stronger-than-expected American inflation data on Wednesday, which had initially supported the dollar and raised questions about the outlook for US interest rates.

Investors are also looking towards Finance Minister Enoch Godongwana's medium-term budget policy statement next week for indications of South Africa's fiscal direction and sovereign credit-rating prospects.

The country's benchmark 2035 government bond strengthened in early trading, with its yield declining by 6.5 basis points to 8.69%, indicating improved demand for South African debt.

JSE recovers as mining and financial shares advance

The JSE's All Share Index recovered from Wednesday's close of approximately 108,515 points, climbing to about 109,199 points by 10.45am, a gain of 0.63%.

The Top 40 Index advanced 0.74% to approximately 101,446 points, supported by gains in financial and precious-metals shares.

The precious-metals and mining sector rose about 2.07%, while financial shares gained approximately 0.78%.

Technology stocks were weaker, reflecting broader international pressure on the sector following a sharp sell-off on Wall Street.

The recovery suggests that South African equities are benefiting from renewed interest in resource and financial counters, even as investors remain cautious about the outlook for global economic growth.

Oil markets have been pulled in opposing directions by the possibility of increased Russian petroleum shipments and renewed attacks on the country's refining infrastructure.

Brent crude futures fell $2.28, or 2.2%, to $103.78 a barrel by 10.29am South African time on Thursday, while US West Texas Intermediate crude declined $1.34 to $93.75.

The decline followed reports that Washington was considering easing restrictions on some Russian tankers operating in the so-called shadow fleet, potentially improving the availability and transportation of Russian petroleum products.

However, Ukrainian strikes on Russian energy infrastructure and attacks on vessels in the Middle East have limited the downward movement.

Ukraine's renewed targeting of Russian refineries is particularly important for the international diesel market.

Damaging a refinery does not necessarily remove crude oil from the global market. Instead, it can reduce the availability of refined products such as diesel, petrol and aviation fuel.

This distinction matters because reduced refinery capacity can push up diesel prices even when crude oil prices remain stable or decline.

The International Energy Agency has previously revised its outlook for Russian oil production in response to Ukrainian attacks, while energy-market researchers have documented significant disruption to Russia's petroleum-product exports.

For South Africa, where road freight, agriculture, mining and industrial production depend heavily on diesel, the consequences could extend well beyond the filling station.

What could happen to oil prices next?

The immediate outlook depends on whether Ukrainian attacks remain concentrated on refineries or expand to crude production, export terminals and transport infrastructure.

The possible easing of US restrictions on Russian tanker movements could also increase the availability of petroleum supplies, offsetting some of the upward pressure caused by infrastructure damage.

An escalation affecting Russian crude exports or shipping through the Middle East would present a more serious threat to global supply.

The result is an unusually uncertain market in which crude oil and refined fuel prices could move in different directions.
