Brent crude rebounded past $105 a barrel on Monday, reversing early-session losses after Ukrainian President Volodymyr Zelenskyy said Russia had already struck energy infrastructure despite the ceasefire agreement brokered under US President Donald Trump's push to pause attacks on Russian and Ukrainian energy assets.

The reversal was swift. Crude opened the week lower, with traders initially pricing in the possibility that an energy ceasefire would reduce the risk premium attached to supplies from the region. Zelenskyy's statement dismantled that assumption within hours, and the market rotated back into crude as a hedge against renewed escalation.

What does the rebound tell us about the ceasefire?

The price action above $105 signals that traders do not believe the agreement will hold — or, at minimum, that they will demand compensation for the risk that it does not. A credible, durable pause on strikes against energy infrastructure would, under normal logic, push oil lower by trimming the threat to production, transit and export capacity in the region.

Monday delivered the opposite sequence: early losses on ceasefire optimism, then a full reversal once Kyiv reported that Moscow had struck energy infrastructure anyway. The market treated the reported strikes as evidence that the deal's terms are not being honored on the ground, and repriced accordingly.

Zelenskyy's accusation is the single most consequential datapoint in the session. It converts what looked like a de-escalation event into a compliance question — and compliance questions in energy markets resolve upward, not downward, until proven otherwise.

Why the Trump-brokered deal moved prices in both directions

The agreement, tied to Trump's effort to wind down the Russia-Ukraine conflict through negotiated pauses, initially registered as a supply-risk reduction. Traders who had sold crude in early dealings were effectively wagering that strikes on energy infrastructure would stop, removing one layer of geopolitical uncertainty from the global balance.

That wager failed within the first trading day. When the Ukrainian president stated that Russia had already hit energy targets despite the deal, the earlier sellers were forced to reassess. Brent climbed after the early losses and pushed back above the $105 mark, recovering the ground surrendered at the open and then some.

The episode illustrates a core principle of how political agreements trade: the announcement moves the market once, and the first evidence of compliance or breach moves it again, usually harder. Monday's session contained both legs — an optimism leg down, a credibility leg back up.

What is at stake for oil buyers and energy planners?

For corporate energy buyers, the message from Monday is that headline-driven relief in crude prices can evaporate before the trading day closes. A settlement above $105, achieved after an early decline, tells procurement teams that geopolitical headline risk remains the dominant variable in the near-term oil price.

The session's shape also matters for risk management. Prices did not merely rise — they reversed. Anyone positioned for the ceasefire to hold was caught by the turnaround. That pattern typically widens intraday volatility around subsequent diplomatic milestones tied to the deal, as each new claim and counterclaim over strikes on infrastructure lands directly into the price.

Key exposures from here:

• Compliance monitoring. Any further Ukrainian reports of strikes on energy infrastructure, or Russian denials, will translate into immediate price reactions. -- Ceasefire durability. The premium above $105 reflects doubt, not certainty; confirmation that attacks have genuinely stopped would test that premium.
• Escalation risk. If strikes continue beyond energy targets, the risk repricing seen Monday would extend.

The bottom line for boards and trading desks

Oil closed the narrative gap on Monday. An energy ceasefire that is breached on day one is not, in market terms, a ceasefire — it is an open question with a $105-plus price tag. Until either side produces durable evidence of restraint, traders will price the agreement as fragile, and every report from the front lines will move crude.

Zelenskyy said Russia had already struck energy infrastructure despite the deal. The market's answer was a rebound past $105. That exchange — one accusation, one reversal — is the whole story of the session, and the reference point against which the next round of headlines will be measured.
