Oil prices remain volatile. The Reserve Bank of Australia signals further rate hikes

On Monday, the US stock indices closed mixed amid ongoing uncertainty surrounding the conflict in the Middle East. By the end of the day, the Dow Jones (US30) rose by 0.32%. The S&P 500 (US500) fell by 0.07%. The Technology Index NASDAQ (US100) closed lower by 0.45%. The main pressure on the market came from the technology sector, which was the worst performer of the day, while shares of energy, financial companies, and consumer‑staples producers rose thanks to high commodity prices and demand for safe‑haven assets.

By the end of the day, Germany’s DAX (DE40) jumped by 1.49%, France’s CAC 40 (FR40) closed up by 0.44%, Spain’s IBEX 35 (ES35) gained 0.75%, and the UK’s FTSE 100 (UK100) ended the session up by 1.26%. Market sentiment improved amid new signals of possible diplomatic progress in the Middle East conflict. Iran reported that it had sent a response to the updated US proposal for ending the war.

According to preliminary data, Switzerland’s economy grew by 0.5% in the first quarter of 2026 compared with the previous quarter, accelerating from 0.2% at the end of 2025. This was the strongest quarterly growth in the past year and indicates a steady recovery after a brief slowdown. Currency dynamics also played a role: during periods of heightened geopolitical tension, the franc traditionally strengthens as a safe‑haven asset, supporting demand for it.

WTI oil prices ended an extremely volatile session near 106 dollars per barrel, retracing most of the initial gains amid conflicting signals about a possible agreement between the US and Iran. Pressure on prices early in the session intensified after Iranian media reported that Washington had allegedly proposed a temporary easing of oil sanctions until a final peace agreement is reached. Later, prices turned upward again after Axios reported that Iran had sent an updated peace proposal, although the White House, according to media reports, considered it insufficient. Despite diplomatic signals, the market remains extremely tense, as the Strait of Hormuz is still restricted for shipping, and attacks on energy infrastructure continue to disrupt oil production and supply.

The US natural‑gas prices (XNG/USD) held near 3.02 dollars per MMBtu, remaining close to their highest levels in the past seven weeks amid expectations of rising demand and ongoing production cuts. The main support for the market comes from expectations of hot weather in the southern and eastern United States, where higher temperatures are expected to increase electricity consumption for air conditioning, and thus boost gas demand from power companies. Market attention was also drawn to reports that the first shipments of US LNG since February 2025 are expected to arrive in China in June, which may signal a gradual recovery in export demand.

In Asia on Friday, Japan’s Nikkei 225 (JP225) fell by 0.97%, China’s FTSE China A50 closed down by 0.89%, Hong Kong’s Hang Seng (HK50) declined by 1.11%, and Australia’s ASX 200 (AU200) dropped by 1.45%.

On Tuesday, the Australian dollar (AUD) fell to around 0.71 US dollars, losing part of the previous session’s gains after signals from the Reserve Bank of Australia about rising inflation risks. RBA Deputy Governor Sarah Hunter warned that the prolonged conflict in the Middle East and the continued rise in energy prices may lead to inflation expectations becoming anchored above the target level. In that case, the regulator may have to tighten monetary policy more aggressively than previously expected, even despite the risk of a more pronounced economic slowdown.
