Structured products maturing in January will provide £669m of rollover money to providers in the UK market, with the top six highest selling products accounting for more than half of the rollover money returning to the market, an estimated £363m.

According to SRP, the £669m of initial sales across 54 products maturing this month will allow 30 UK providers to launch rollover products, although it represents a 38.5% decrease compared to the £927m that matured in December across 69 products.

Barclays, with ten products set to mature this month from five of its distribution outlets including Barclays Bank (5), Barclays Capital (1), Barclays International (1), Barclays Stockbrokers (1), and Barclays Wealth (2), will see the most products maturing this month. The combined estimated volume for Barclays' maturing products is over £95m. Santander, with six products and over 138m of estimated sales, and HSBC, with five products and over £125m of estimated sales, complete the top three for January maturities.

The highest selling maturity in January is Abbey's Guaranteed Growth Plan 15, a 3.5-year growth capped call linked to the FTSE100 hedged by Abbey National, which sold £89.7m and will return the minimum 105% despite the underlying performance in mid-January. The second top-selling maturity in January will be HSBC Investment's Guaranteed Capital Account 1, a six-year growth and income uncapped call deposit linked to the FTSE100. This capital-protected product, which sold an estimated £87.5m, will mature at the end of the week.

The third best-selling maturity in January is a Close Fund Management product which sold an estimated £49m back in December 2005. Close Brother's Japanese Accelerated Return Fund II is a six-year capital-at-risk protected tracker linked to the performance of the Nikkei225 index. Investors in this product will incur in losses as the underlying struck at 16107 and has fallen below 50% of its initial level.

Potential knockout products maturing early in the UK could add an extra £200m in rollover opportunities across 22 products and 15 providers. The average ticket size for all the products maturing in January is £12.3m compared to December's average of £13.6m.
