If the end is nigh, I’d rather invest for the short term

If the end of the world is really nigh, should I be investing in shorter-term savings schemes rather than a pension? I currently contribute 20% of my £117,000 salary to my pension and my employer pays 5%. I’m 44 and worry about imminent world wars over dwindling resources. I find it hard to believe a peaceful 20-year retirement beckons. Is there a way to invest in things I could access quickly if the poop really does hit the fan?

I sincerely hope your fears prove unfounded, but apocalyptic predictions will be prompting many to ask the same question. However, decisions around pension savings should not be taken lightly. I consulted Helen Morrissey, head of retirement analysis at Hargreaves Lansdown. She points out that your pension is not necessarily locked away until you reach state pension age and you can access a private pension pot at 55. The age limit rises to 57 in 2028, which means you could have your hands on your money in 13 years.
