Dec 29 (Reuters) - Swedish landlord SBB and its unit Offentliga Hus I Norden will defer interest payments on all its hybrid bonds as the country's commercial real estate crisis deepens.

SBB has taken this measure to strengthen its liquidity, the company said in a statement on Friday.

Last month, SBB paid back some debt early, buying more than 400 million euros ($442 million) of bonds and securities at a small discount as it scrambled to tackle a multi-billion debt pile.

The company's problems are unfolding as Sweden struggles to contain a wider property crisis, triggered by high debts, rising interest rates and a wilting economy.

The sector's difficulties have alarmed investors and prompted the Swedish central bank to issue several warnings.

Earlier this month, Riksbank Governor Erik Thedeen said that Swedish property companies must reduce debt and strengthen their balance sheets amid surging interest rate costs and a slowing economy.
