The rate of inflation has fallen to 3.2%, leading to speculation that the Bank of England will cut the base interest rate. In 2025, interest rates have fallen several times, and there have been updates to the FSCS and changes to the ISA rules. For wealthy savers holding excess cash, now might be the right time to rethink their cash strategy. We explore this topic in more detail and the latest changes to protection and saving limits.
Inflation vs interest: the cost of holding cash
Although cash can feel safe, the latest changes to rules, protection limits, and inflation mean that structuring your money matters more than ever. The cost of ‘comfort cash’ could mean that you are missing out on potential investment returns or low interest from standard savings accounts.
Even with recently improved interest rates, inflation erodes the real value of cash over time.
Therefore, if you’re a wealthy saver holding large cash balances for your ‘comfort’, you may end up paying an opportunity cost in the long term. Instead of holding cash in one big pot, a more tangible, structured financial strategy could provide you with better returns.
When do the Cash ISA rules change?
The annual Cash ISA (Individual Savings Account) limit is being reduced to £12,000 in April 2027 for the under-65s. The aim is to encourage savers to invest part of their money into Stocks & Shares ISAs. The annual savings limit for the over-65s will remain at £20,000 until April 2031 for Cash ISAs and Stocks & Shares ISAs.
According to research by KPMG, it’s estimated that up to “87% of UK adults with cash ISAs won’t invest in stocks and shares if the cash ISA allowance is reduced”. Also, 58% of those surveyed stated that the reforms won’t affect the way they use their Cash ISAs. Interestingly, those aged between 25 and 34 are the most likely to invest their cash into stocks and shares.
It’s likely that most savers won’t change their habits following the changes to Cash ISAs. However, those who do review their financial plans and take action will be better protected.
FSCS Protection Changes
From 1 December 2025, the FSCS (Financial Services Compensation Scheme) limit increased from £85,000 to £120,000 per person. This protection limit only applies per authorised firm, instead of a singular bank brand. As an example, HSBC Holdings plc owns HSBC and First Direct banks, so if the holding company fails, you can only claim against one account.
Temporary High Balance (THB) protection has also risen from £1 million to £1.4 million. If you hold a large cash balance, there’s still a risk of this being under-protected, especially if your money is held within banking groups without diversification.
Benefits of a three-bucket investment strategy
Your cash shouldn’t just sit in one big pot. Instead, by spreading your money across different ‘buckets’, you can achieve the right balance between saving and investing.
At Balance: Wealth Planning, we use a three-bucket investment strategy to manage our clients’ cash balances.
Below is a short summary of how our bucket strategy helps our clients:
- Bucket 1: short-term cash that provides safety and easy access
- Bucket 2: medium-term spending that enables balanced growth
- Bucket 3: long-term, inflation-beating investments
This cash strategy gives our clients greater security and promotes long-term growth. They can save and invest with fast access to a pot of money. The longer durations enable them to invest for growth and better investment returns.
