Martin Lewis: when not to save your money

Martin Lewis advises against saving if you have high-interest debt, a mortgage rate matching or exceeding savings rates, or surplus cash for long-term investment. He suggests prioritizing debt repayment over saving when interest rates on debt are significantly higher. Investing may offer better returns for funds not needed for at least five years, provided an emergency fund is established. Lewis also highlights current high savings rates, urging people to move from low-interest accounts. Tax implications on savings interest and ISA benefits are also mentioned.
