Crude oil ‘mini-glut’ won’t save markets—energy shocks from Hormuz to Taiwan and Cuba are stacking up

China’s Ministry of Natural Resources says it discovered 200 medium- and large-sized mineral deposits in 2025, while investment in non-oil-and-gas geological exploration rose to 25.25 billion yuan (about $3.0 billion). The announcement signals a continued push to secure upstream inputs beyond hydrocarbons, including minerals that can support energy transition supply chains. While the figure is framed as a domestic resource-development milestone, it also reads as strategic industrial positioning at a time when global commodity availability is increasingly tied to geopolitics. For markets, the message is less about immediate output and more about future bargaining power and resilience in critical materials. Separately, multiple articles point to energy security stress across regions that are exposed to shipping chokepoints, import dependence, and grid fragility. The Hormuz-focused reporting highlights that Taiwan is 99% dependent on imported natural gas, with about one-third of its 23.6 Mt LNG imports in 2025 coming from the Gulf—mostly Qatar (nearly 8 Mt) and additional volumes from the UAE. That dependence turns a “diversification debate” into a live stress test: any disruption risk in the Strait of Hormuz can quickly translate into power-grid instability. Meanwhile, Cuba’s blackout coverage describes a rapidly deteriorating domestic situation, with officials blaming the United States while residents report prolonged outages and fuel reserves “running out,” culminating in protests in Havana. On the markets side, the crude oil piece warns that a “surprising mini-glut” is real but may not prevent a broader energy disaster that could be only weeks away, implying that near-term oversupply signals could be misleading. If Hormuz risk or LNG logistics tighten, the most direct transmission would be into LNG benchmarks, power generation costs, and regional gas spreads, with knock-on effects for utilities and industrial users. Taiwan’s LNG exposure makes it particularly sensitive to freight rates, spot cargo availability, and any risk premium embedded in Gulf-origin supply, while Cuba’s fuel depletion raises the probability of demand destruction and higher local scarcity costs that can spill into regional insurance and shipping sentiment. China’s mineral-discovery narrative is longer-dated, but it supports the view that Beijing is building a pipeline of critical inputs that can eventually cushion downstream manufacturing and energy-transition projects. The next watchpoints are clear: for Taiwan, monitor LNG contract repricing, Gulf shipping risk indicators, and grid reliability metrics that could force load-shedding decisions. For oil, track whether the “mini-glut” persists in inventories and refining runs or flips quickly as supply disruptions and risk premia reassert themselves. For Cuba, the key triggers are whether fuel reserves are replenished, whether outages broaden beyond the reported provinces, and how quickly authorities can stabilize power restoration without escalating unrest. Across the cluster, escalation or de-escalation hinges on whether Hormuz-related disruption risk remains contained and whether domestic energy shortfalls in Cuba are managed without further political confrontation.

Geopolitical Implications

• 01

  Energy chokepoints (Hormuz) are increasingly acting as strategic leverage points that can translate quickly into domestic grid stability for import-dependent economies like Taiwan.

• 02

  Domestic energy scarcity in Cuba is becoming a political flashpoint, with external blame narratives (U.S.) potentially hardening positions and complicating stabilization diplomacy.

• 03

  China’s critical-mineral exploration expansion suggests Beijing is preparing for supply-chain competition over non-hydrocarbon inputs that underpin energy transition and industrial capacity.

Key Signals

• —Taiwan: LNG spot/term contract repricing, cargo diversion risk, and grid reliability/load-shedding indicators.
• —Oil: inventory and refining-run data to confirm whether the 'mini-glut' is structural or fading quickly.
• —Shipping/insurance: changes in freight rates and marine insurance premia for routes linked to Hormuz.
• —Cuba: verification of fuel-reserve replenishment, breadth/duration of outages by province, and protest intensity in Havana.
