UK - Defined contribution pension funds have returned to the value they were before the recession started in September last year, Aon Consulting figures showed.
The value of DC funds has swung from a record dip of £344bn (US$567.3bn) in March this year to present levels of about £450bn.
Aon's DC Pension Tracker measures the total asset value of UK workers' DC pension accounts.
For July total DC assets in the UK were worth £451bn - only a billion more than their £450bn value in September 2008. This month's figures rose by £31bn, or 6.8%, in the month to July 31 from £420bn at the end of June.
The gains are largely thanks to rallies in the equity markets, and demonstrate the volatility of UK workers' retirement savings.
Aon Consulting head of DC Helen Dowsey said: "These figures look promising as we return to asset figures roughly at the same value as they were a year ago. However, this month's figures serve to underline the volatile nature of DC investment."
She explained: "Someone retiring at the end of July may have a significantly higher projected retirement income than someone retiring a month before. These volatile conditions highlight the need for workers to pre-plan for their pension, and understand and regularly review their investments, whose value can change dramatically in a short space of time.
"Employers and trustees of occupational DC schemes have a key role in educating their DC scheme members - particularly those approaching retirement - to help them understand what they can do within their pension investments to mitigate this volatility."
