US President Donald Trump announced a complete blockade of the Strait of Hormuz, a critical passage for nearly 20% of global energy supply, following the collapse of US-Iran peace talks over Iran's refusal to drop its nuclear ambitions [1][3][4][5]. The blockade, confirmed by both Trump and US Central Command (CENTCOM), officially began on April 13 at 10:00 AM ET (14:00 GMT) [1][3][4][5]. Trump stated, “Effective immediately, the United States Navy... will begin the process of BLOCKADING any and all ships trying to enter, or leave, the Strait of Hormuz,” and instructed interdiction of vessels paying tolls to Iran [1].
The immediate market reaction was characterized by a sharp rally in crude oil prices, with WTI trading around $97.00 at the start of the week [1][5]. However, both the US Dollar and oil prices showed little immediate movement after the official announcement, as the market had already priced in the news following earlier CENTCOM communications [3][5]. The US Dollar Index (DXY) rose 0.3% to near 99.00, and was the strongest against the British Pound, which fell 0.45% on the day [1][2]. The GBP/USD pair snapped a five-day winning streak, trading around 1.3400, while the USD/INR pair surged to near 93.35 as the Indian Rupee weakened due to higher oil prices [1][2].
Global equities responded with modest declines, with most Asian benchmarks and US futures down around 1% or less, reflecting a more muted reaction compared to previous geopolitical shocks [5]. Gold prices slipped 0.5% to $4,720.28 per ounce, as a firmer dollar reduced bullion's appeal [5]. Bond yields rose, with Japan’s 10-year government bond yield climbing to 2.47% on Monday, driven by inflation concerns from higher energy costs [4][5].
Analysts noted that markets appear to have moved past 'peak fear and sell-off,' with volatility indicators such as the VIX suggesting the worst panic has subsided [5]. Billy Leung of Global X ETFs commented that investors are now more accustomed to geopolitical shocks, and Jun Bei Liu of Ten Cap observed that the market is now trying to 'work itself out' after the initial panic [5]. However, Leung highlighted that the US administration faces a limited window to secure congressional approval for military action, which could introduce further uncertainty in the coming weeks [5].
Forward-looking statements from central banks and policymakers reflect ongoing concerns. The Federal Reserve is expected to maintain a hawkish stance due to inflation risks, while the Bank of England signaled a potential rate hike as early as April, and the Reserve Bank of Australia is anticipated to raise rates again in May [1][2][4]. The Bank of Japan will evaluate the impact of elevated energy prices at its April 28 meeting [4]. US President Trump acknowledged that gas prices could remain elevated through the November elections, contradicting his earlier statements that energy price increases would be temporary [1].
CONCLUSION
The US blockade of the Strait of Hormuz has driven oil prices higher and reinforced inflation concerns, but overall market reactions have been relatively muted, with equities and gold showing only modest moves. Analysts suggest that markets have largely priced in the geopolitical risks, though the political timeline for US military action remains a key uncertainty. Central banks are expected to maintain or increase rates in response to persistent inflation pressures.
