Dollar index slips as US-Iran deal cools haven demand and pares Fed rate-hike bets

    The US Dollar Index (DXY), which tracks the US Dollar (USD) against six major currencies, slipped to around 99.50 in Asian trading on Monday as demand for safe-haven assets eased. Reports that the US and Iran have reached an agreement to end their conflict reduced concerns over inflation and the prospect of higher interest rates, putting pressure on the Greenback.

    Washington and Tehran said on Sunday that the deal will take effect on Friday. US President Donald Trump said the US would lift its naval blockade on Iranian ports and that the Strait of Hormuz would reopen once the agreement is signed. The UK, France, Germany and Italy said they were prepared to lift sanctions on Iran in response to steps on its nuclear programme, while Iran’s National Security Council confirmed a ceasefire and said final talks would begin after commitments under the memorandum of understanding are met; Iranian officials also called for the maritime blockade to end immediately. The CME FedWatch tool shows markets pricing nearly a 27% probability of a US Federal Reserve (Fed) rate rise in December, down from 40% a week earlier.

    Market Positioning on Dollar, Rates, and Treasuries

    Given the US Dollar Index’s slide towards 99.50, we see a clear opportunity to position for further dollar weakness. This drop from levels above 104 just last month is significant, so we are buying put options on dollar-tracking ETFs. We are also establishing long positions in EUR/USD call options, as European currencies stand to gain disproportionately.

    The shift in Fed policy expectations is a major catalyst for fixed-income markets. With the probability of a December rate hike plummeting to 27%, we anticipate Treasury yields will continue their decline from the recent highs seen in May. We are increasing our exposure to long-dated Treasury note futures to capitalize on rising bond prices.

    Geopolitical De-Escalation: Impact on Energy, Volatility, and Equities

    This geopolitical de-escalation directly impacts energy prices, creating a clear bearish signal for crude oil. WTI crude futures have already broken below $75 a barrel, a reversal of the risk premium built up over the past year. To profit from an expected further slide as Iranian supply comes online, we are selling crude oil futures and buying puts on major energy sector ETFs.

    The reduction in global risk is causing volatility to collapse, with the VIX falling below 12 for the first time since last summer. This “risk-on” environment is highly bullish for equities, especially technology and consumer sectors that benefit from lower rate expectations. We are therefore buying call options on the S&P 500 and Nasdaq 100 indices, targeting new highs in the coming weeks.

    The lifting of sanctions by European nations opens up a major export market and eases energy cost pressures for the continent. We’ve already seen Germany’s DAX index rally over 2% on the news, reflecting its heavy reliance on manufacturing exports. We view this as the start of a trend and are adding exposure to call options on European stock indices.
