Another month, guess what, take a lucky guess, it is the same old story, HM Government, spends more money than it receives via taxes and duties.
Now we are in a Covid 19 world. UK’s HM Government needs to fund many new demands. [www.dmo.gov.uk]

Another deficit month, thus to bridge the gap, needs to borrow on the bond market In April 2021 , the HM Government had to borrow money to meet the difference between tax revenues and public sector expenditure. The term for this is The PSNCR: The Public Sector Net Cash Requirement. There were “only” 8 auctions of Gilts (UK Government Bonds) by the UK Debt Management Office to raise cash for HM Treasury:-

28-Apr-2021 0 1/8% Index-linked Treasury Gilt 2031 3 months £1,113.6500 Million
21-Apr-2021 0 5/8% Treasury Gilt 2035 £3,124.9990 Million
20-Apr-2021 0 1/8% Treasury Gilt 2024 £4,062.4980 Million
14-Apr-2021 0 1/8% Index-linked Treasury Gilt 2051 3 months £713.8250 Million
13-Apr-2021 1 5/8% Treasury Gilt 2071 £1,000.0000 Million
08-Apr-2021 0¼% Treasury Gilt 2031 £3,437.5000 Million
07-Apr-2021 0 3/8% Treasury Gilt 2026 £3,394.0000 Million
07-Apr-2021 0 7/8% Treasury Gilt 2046 £2,000.0000 Million

Thus:-

£1,113.6500 Million + £3,124.9990 Million + £4,062.4980 Million + £713.8250 Million + £1,000.0000 Million + £3,437.5000 Million + £3,394.0000 Million + £2,000.0000 Million = £18,846.472 Million.

£18,846.472 Million = £18.846 Billion

Another way of looking at it, is in the 30 days in April 2021, HM Government borrowed:£628.21573333333333333333333333333 Million each day for the 30 days. We are fortunate, while the global banking and financial markets still has the confidence in HM Government to buy the Gilts (Lend money to the UK), the budget deficit keeps rising. What is also alarming, is the dates these bond mature from 2024 through to 2071. All long term borrowings, we are mortgaging our futures, but at least “We Are In It Together…“
