    Japan’s Finance Minister Satsuki Katayama said G7 finance ministers and central bankers agreed that fluctuating oil prices are causing high volatility in financial markets and foreign exchange markets. She said Japan has been in close contact with G7 counterparts and will continue delivering messages. Katayama said she would not comment on Japanese Government Bond yield levels. She also said the government has not estimated the cost of continuing subsidies aimed at keeping petrol prices in check.

    Support For Southeast Asia Partners

    She said there are no issues with the amount of oil stock, but raised the question of support for partners in South East Asia. She said policymakers are reviewing all scenarios for oil stockpiles, including optimistic and pessimistic ones. At the time of writing, USD/JPY was up 0.03% on the day at 159.70. The G7’s focus on oil-driven volatility is a critical signal for us right now. With West Texas Intermediate (WTI) crude recently breaking past $95 a barrel on renewed Middle East tensions, markets are pricing in more uncertainty. We are seeing this directly in the VIX, which has climbed over 21 this past week, a sharp increase from the low teens we saw in February 2026. This environment puts immense pressure on the Japanese Yen, given Japan’s status as a major energy importer. We should anticipate continued choppiness in the USD/JPY pair, which is already hovering near the 160 level that triggered verbal interventions in the past. Traders should consider using options to hedge against a sudden spike in currency volatility or a sharp move in either direction.

    Defensive Positioning For Equity Markets

    For equity markets, this warning from policymakers suggests a defensive posture is warranted. High and unstable energy prices can erode corporate margins and dampen consumer spending, creating headwinds for indices like the Nikkei 225. We should look at buying put options on broad market indices as a cost-effective way to protect portfolios against a potential downturn in the coming weeks. Direct plays on energy volatility itself are also attractive. The oil markets are reacting to every headline, and policymakers have admitted they are scenario-planning for both optimistic and pessimistic outcomes regarding supply. Using derivative strategies like long straddles on crude oil futures could be an effective way to profit from large price swings, regardless of the direction. Looking back at the second half of 2025, we remember how a similar surge in energy prices stalled the expected central bank pivot, causing a sharp sell-off in bond markets. That historical precedent shows how quickly sentiment can shift based on oil fluctuations. This reinforces the need to be prepared for sustained volatility across asset classes, not just in the energy sector. Create your live VT Markets account and start trading now.
