The British Pound is down 0.13% to near 1.3415 against the US Dollar (USD) during the European trading session on Thursday. The GBP/USD pair faces selling pressure as optimism towards the United States (US)-Iran deal fades, following comments from Iran’s Supreme Leader that near-weapons-grade uranium must stay in Iran.
The statement from Iran’s top leader is in contrast with Washington’s demand that Iran must surrender its uranium enrichment if it wants a deal.
Iran Supreme Leader’s comments regarding the retention of near-weapons-grade uranium have dampened the market sentiment. S&P 500 futures surrender its entire early gains and drops to near 7,400. The US Dollar Index (DXY), which tracks the Greenback’s value against six major currencies, bounces back swiftly to near 99.30.

On Wednesday, market mood turned risk-on after comments from US President Donald Trump signaled that a deal with Iran is around the corner. Trump said that Washington is in the “final stages” of finalizing a deal with Iran.
The British Pound is also facing pressure from weak preliminary United Kingdom (UK) S&P Global Purchasing Managers’ Index (PMI) data for May.
The data showed during the European trade that the UK Composite PMI surprisingly declined in May, as the service sector activity contracted. The Composite PMI arrived at 48.5, while it was expected to expand again, but at a moderate pace to 51.7 from April’s reading of 52.6. A figure below 50.0 is considered a contraction in the business activity.
Going forward, investors will focus on the UK Retail Sales data for April, which will be released on Friday.
Risk sentiment FAQs
In the world of financial jargon the two widely used terms “risk-on” and “risk off'' refer to the level of risk that investors are willing to stomach during the period referenced. In a “risk-on” market, investors are optimistic about the future and more willing to buy risky assets. In a “risk-off” market investors start to ‘play it safe’ because they are worried about the future, and therefore buy less risky assets that are more certain of bringing a return, even if it is relatively modest.
Typically, during periods of “risk-on”, stock markets will rise, most commodities – except Gold – will also gain in value, since they benefit from a positive growth outlook. The currencies of nations that are heavy commodity exporters strengthen because of increased demand, and Cryptocurrencies rise. In a “risk-off” market, Bonds go up – especially major government Bonds – Gold shines, and safe-haven currencies such as the Japanese Yen, Swiss Franc and US Dollar all benefit.
The Australian Dollar (AUD), the Canadian Dollar (CAD), the New Zealand Dollar (NZD) and minor FX like the Ruble (RUB) and the South African Rand (ZAR), all tend to rise in markets that are “risk-on”. This is because the economies of these currencies are heavily reliant on commodity exports for growth, and commodities tend to rise in price during risk-on periods. This is because investors foresee greater demand for raw materials in the future due to heightened economic activity.
The major currencies that tend to rise during periods of “risk-off” are the US Dollar (USD), the Japanese Yen (JPY) and the Swiss Franc (CHF). The US Dollar, because it is the world’s reserve currency, and because in times of crisis investors buy US government debt, which is seen as safe because the largest economy in the world is unlikely to default. The Yen, from increased demand for Japanese government bonds, because a high proportion are held by domestic investors who are unlikely to dump them – even in a crisis. The Swiss Franc, because strict Swiss banking laws offer investors enhanced capital protection.
