Warsaw Stocks Climb to New High as WIG30 Surges 3.50%

Poland's main index ended Wednesday at a record level, with broad advances across basic materials, banking and construction names. WIG30 rose 3.50% to an all-time high as several heavyweights recorded double-digit percentage moves. Commodity prices fell sharply, while the zloty strengthened versus major currencies.

Key Points

  • WIG30 closed up 3.50%, hitting a new all-time high.
  • Gains were led by Basic Materials, Banking and Construction sectors; mBank (WA:MBK) reached an all-time high.
  • Crude and Brent oil prices fell sharply while gold futures rose; the zloty strengthened versus the euro and the dollar.

Poland's equity market closed higher on Wednesday, with the benchmark WIG30 index finishing the session up 3.50% to reach a new record. Strength was concentrated in the Basic Materials, Banking and Construction sectors, which together drove the broader market advance in Warsaw.

The strongest performer on the WIG30 was Rainbow Tours SA (WA:RBW), which climbed 11.45% - adding 15.00 points to finish at 146.00. KGHM Polska Miedz SA (WA:KGH) rose 9.85%, gaining 27.30 points to end the day at 304.50. mBank SA (WA:MBK) advanced 9.41% or 108.00 points to close at 1,256.00, a level noted as an all-time high for the stock.

On the downside, Jastrzebska Spotka Weglowa SA (WA:JSW) was the weakest WIG30 name, falling 11.08% or 3.85 points to 30.90 at the close. Polski Koncern Naftowy ORLEN SA (WA:PKN) declined 2.84%, down 3.84 points to finish at 131.16, while Orange Polska SA (WA:OPL) slipped 2.25% or 0.32 points to 13.71.

Breadth on the Warsaw Stock Exchange favored advancers: 373 stocks rose, 200 fell and 97 ended unchanged.


Commodities traded with large moves on the day. Crude oil for May delivery declined 15.19% - down $17.16 to $95.79 a barrel. Brent oil for June delivery fell 12.89%, a drop of $14.09 to $95.18 a barrel. By contrast, the June Gold Futures contract rose 2.08%, gaining $97.56 to trade at $4,782.26 a troy ounce.

Currency markets showed the Polish zloty firming against both the euro and the dollar. EUR/PLN moved lower by 0.47% to 4.25, while USD/PLN fell 1.31% to 3.63. The US Dollar Index Futures was down 1.11%, at 98.58.


This session featured pronounced sector-level dispersion, with notable participation from basic materials and banking stocks that contributed to the WIG30's record close. Movements in oil and gold, alongside FX shifts, were significant components of the market context on the day.

Market participants should note the mix of strong gains among some heavyweight names and steep declines in others, underscoring variability across sectors and individual issuers.

Risks

  • Significant single-session declines in some large-cap names - such as Jastrzebska Spotka Weglowa SA (WA:JSW) - indicate potential volatility for the Basic Materials sector.
  • Sharp falls in oil prices may affect energy-related companies and indices exposed to hydrocarbon producers, such as Polski Koncern Naftowy ORLEN SA (WA:PKN).
  • Currency fluctuations - notably moves in EUR/PLN and USD/PLN - can impact firms with foreign-currency exposures, including those with imported inputs or foreign-denominated debt.
