Escalating tensions between the United States and Iran have triggered a broad risk-off move in global markets, supporting the US Dollar and weighing on several major currencies and commodities. According to Bloomberg, US forces struck Iranian targets after President Trump vowed that Tehran 'will pay' for the killing of three US soldiers, with US Central Command confirming a new wave of strikes on Monday, marking the tenth consecutive day of attacks [4]. This escalation has pushed crude oil prices higher, intensifying inflation concerns and prompting expectations that central banks may hold interest rates at elevated levels for longer [4].
The Japanese Yen remains in a stalemate, with USD/JPY trading near 162.50 and showing little movement over the past two weeks, despite significant interventions by the Ministry of Finance, including a reported 5.5 trillion Yen operation to defend the 160 level [1]. The Bank of Japan's rate hike to 1.00% in June failed to shift the negative real policy rate, and the wide rate gap with the US Federal Reserve (holding at 3.75%) continues to favor the Dollar. Upcoming Japanese trade data and CPI releases are expected to reinforce the Yen-negative structural outlook, as energy import costs remain elevated due to disrupted Gulf supply [1].
The Malaysian Ringgit has also weakened against the US Dollar, with USD/MYR closing at 4.0970, as renewed US-Iran tensions and broader risk aversion outweighed stronger-than-expected Malaysian GDP and improved foreign equity flows [5]. OCBC notes that while domestic fundamentals are resilient, fading policy support after Bank Negara Malaysia held rates and lingering political uncertainty ahead of the 1 August Negeri Sembilan election may temper sentiment. The bank expects USD/MYR to stay supported if geopolitical risks persist, though improving portfolio flows should limit further Ringgit weakness [5].
Gold prices have edged lower to near $4,000 as the risk-off environment and rising oil prices diminish the metal's appeal as a non-yielding asset [4]. UBS analyst Giovanni Staunovo highlights gold's negative correlation to oil prices, with market participants closely monitoring Middle East developments. Despite softer US inflation data, swap traders have fully priced in at least one more Federal Reserve rate hike by year-end, and Cleveland Fed President Beth Hammack emphasized persistent inflation risks, reinforcing expectations for sustained restrictive policy and a stronger Dollar against the Euro and Yen [4].
Other major currencies are also feeling the impact. The British Pound has declined for three consecutive days against the Dollar, with GBP/USD trading down around 0.17% on Monday, as markets digest the appointment of Andy Burnham as Prime Minister and anticipate a series of key UK economic data releases this week [3]. The Australian Dollar remains capped below the 0.7000 level, with risk appetite propped up mainly by hopes for US-Iran talks, while the People's Bank of China held rates steady despite weaker-than-expected GDP growth [2].
CONCLUSION
Heightened US-Iran tensions have fueled a global risk-off move, supporting the US Dollar and pressuring currencies such as the Yen, Ringgit, Pound, and Aussie, as well as gold prices. Market participants are bracing for continued volatility, with central banks expected to maintain a hawkish stance amid persistent inflation and geopolitical uncertainty. The overall market takeaway is one of caution, with external risks overshadowing domestic fundamentals across several economies.
