New-home prices in 70 cities excluding state-subsidised housing declined 0.19% from March, the smallest drop in a year per National Bureau of Statistics data released Monday. Property-bottom thesis reinforced as the multi-year downturn approaches the floor. Separately, the White House Sunday fact sheet confirmed China will buy at least $17bn annually in US agricultural goods through 2028 following the Trump-Xi summit.

04 · Energy — Brent Jumps to $111 After Drone Strike on UAE Barakah Nuclear Plant

A drone strike caused a fire at an electrical generator on the perimeter of UAE’s Barakah Nuclear Energy Plant in Al Dhafra Sunday May 17.

Strategic convergence priorities include defence-technology transfer, maritime domain awareness, and rare-earth supply-chain diversification. Vietnam’s dong at 25,400 ($0.0000394); the bilateral $20bn trade target through 2028 the operative goal.

FAQ

What does Japan’s Q1 GDP print mean for global investors?
The 08:50 JST release is the first hard data point on whether the Iran-war energy shock has derailed Japan’s moderate recovery. A print at or above the +1.7% consensus pulls forward the BoJ rate-hike timeline toward June 17-18 and removes one obstacle to yen normalisation. For LATAM allocators reading EM carry-trade dynamics, a hawkish BoJ pivot compresses the 300bp interest-rate differential and triggers yen carry-trade unwinding that historically flows into Brazilian real and Mexican peso defensive positioning.

How serious is the UAE Barakah drone strike for Asian markets?
The Sunday drone strike on the Barakah nuclear plant — three drones, two intercepted, one generator fire, no radiological impact — is materially more serious than a routine missile exchange because it targeted civilian nuclear infrastructure. Brent jumped to $111.30 from Friday’s $107.71. For Asia, which imports 75% of regional energy, the transmission is direct: Japan’s import bill rises against the already-weak yen, India’s bill complicates Modi’s austerity programme, Korea’s energy-importer fragility reasserts. The IAEA‘s grave concern statement establishes the international-coordination response.

Why does the Sara Duterte impeachment matter beyond Manila?
The Senate court convening under a 13-11 unstable majority after last Wednesday’s gunfire incident at Senate premises is institutional fragility within an ASEAN founding member and US Indo-Pacific anchor. Vice President Duterte has announced her plan to seek the presidency in 2028; the trial outcome determines whether the Marcos-Duterte rupture consolidates or contains. For Brazilian and Argentine investors with ADR exposure to Philippine equities (Ayala, SM, Bank of the Philippine Islands), institutional stability is the operative thesis through Q3.
