The rand started the trading week on the back foot, weakening to R16.72/$ from R16.65 on Friday. The local currency has lost more than 1% over the past week.
The dollar index, which measures the US currency’s strength against a basket of currencies, was 0.1% higher at 98.269. The index, which has slipped from the highs reached in the immediate aftermath of US strikes on Iran in early March, continues to find support in the absence of a resolution to the Middle East conflict.

Emerging market currencies against the dollar, over the past year.
Markets remained cautious after Iranian news agency Fars reported that two missiles had hit a US warship near Jask on the Gulf of Oman after it ignored Iranian warnings about entering the Strait of Hormuz, prompting it to turn back. US Central Command denied the reports.
The US military said two US Navy guided-missile destroyers had entered the Gulf to break an Iranian blockade and that two US merchant ships had transited the Strait of Hormuz.
“The blockade is what’s keeping everything on hold and as long as everything is on hold the dollar will remain steady,” said Juan Perez, director of trading at Monex US in Washington.
“However, risk appetite is going to immediately increase the moment there is any type of peace deal. That’s going to hurt the dollar,” Perez said. The euro was down 0.1% at $1.17135 after German Chancellor Friedrich Merz sought to downplay a rift with US president Donald Trump after the US announced plans to draw down troops from Germany. The country’s economy ministry said on Sunday that Berlin is also in touch with the European Commission as it holds talks with Washington, after US president Donald Trump said on Friday he would increase tariffs on cars and trucks from the EU to 25%.
“In the grand scheme of things, it (auto tariffs) is definitely not a positive, but it’s not going to be the main driver,” SEB FX strategist Amanda Sundström said.
“The situation in the Middle East is definitely the dominant factor now. If that reaches some de-escalation or more stable situation, that’s going to be positive for the euro.”
The dollar was 0.05% lower against the yen after the Japanese currency climbed by as much as 0.75% to 155.69 earlier in the session. Ministry of Finance officials did not immediately respond to requests for comment after the move on Monday, but traders remain on alert for action by authorities following suspected intervention by them last week to bolster the battered currency.
“The case for intervention is strong, given the inflationary impact of a weaker yen via import prices, a US administration broadly comfortable with such action, and Japan’s ample FX reserves,” said Roberto Cobo Garcia, head of G10 FX strategy at BBVA.
“We expect intervention to remain effective in capping dollar-yen below 160, as in 2024, with the Ministry of Finance likely to defend this level if tested again in the coming weeks.”
Tokyo officials declined to confirm whether they had intervened last week, but sources told Reuters the authorities had bought yen for the first time in two years. Money market data on Friday showed Tokyo may have spent as much as 5.48 trillion yen (R585 billion) buying the currency.
The British pound was down 0.1% at $1.35655. British markets are closed on Monday for a public holiday.
The Australian dollar was down 0.2% at $0.71905. The Reserve Bank of Australia is due to announce its next policy decision on Tuesday, with the majority of analysts polled by Reuters expecting a hike in the cash rate to 4.35%.
Bitcoin was little changed at $79 442, after earlier trading above $80 000 for the first time since January 31.
