HQ Bank said its risk was SEK 33M — the loss was SEK 1.23B, and the licence was gone
HQ Bank's derivatives portfolio carried far more risk than admitted. When the loss hit SEK 1.23B, regulators revoked its licence and the bank collapsed.

What happened
HQ Bank was a Swedish investment bank founded by Sven Hagströmer and Mats Qviberg — the 'H' and 'Q' in the name. In early 2010, the bank closed its trading activities and disclosed a loss of SEK 1.23 billion (approximately $150 million) in its derivatives portfolio. The loss was catastrophic enough on its own, but what made it a scandal was the discrepancy: the bank had estimated its portfolio's market risk at just SEK 33 million as of March 2010. The actual loss was 37 times the bank's own risk assessment.
The Swedish Financial Supervisory Authority investigated and found 'major deficiencies' in HQ Bank's trading operations. On August 28, 2010, the regulator revoked the bank's banking licence and applied to force the bank into liquidation. Carnegie Investment Bank bought HQ Bank's remains for SEK 268 million. The bank's board members were prosecuted for fraud but acquitted — the court ruled they had not intentionally reported false values.
The final act came in December 2017, when HQ Bank filed for bankruptcy. The cause was not a trading loss but the legal aftermath: the bank could not pay SEK 240 million in legal fees incurred by its board members. The crash is considered one of the largest banking collapses in Swedish history.
Why it happened
- HQ Bank's risk models dramatically underestimated the real risk in its derivatives portfolio — the estimated risk was SEK 33M, the actual loss was SEK 1.23B, a 37x miss.
- The bank's trading operations lacked the risk controls and oversight that a portfolio of that size required — the regulator found 'major deficiencies' in how the bank managed its trading.
- Board members were prosecuted for fraud but the court found no intent — the failure was systemic, not criminal, suggesting the whole governance structure was inadequate.
The lesson
When a bank's own risk estimate misses the actual loss by a factor of 37, the problem is not a bad trade — it is that the bank does not know what it is doing. No regulator can fix that.
Aftermath
The HQ Bank collapse is one of the largest banking failures in Swedish history. The loss of SEK 1.23 billion led to the revocation of the bank's licence, the sale of its assets to Carnegie Investment Bank, and a lengthy legal battle. Board members were prosecuted for fraud but acquitted. The bank ultimately filed for bankruptcy in 2017, unable to pay SEK 240 million in legal fees. The case highlighted the gap between how banks estimate risk and the actual risk they carry, and the limitations of relying on self-reported risk metrics for regulatory oversight.
