The Lloyds (LSE:LLOY) share price has delivered phenomenal gains in recent years, more than doubling since the end of 2024, and climbing yet another 31% over the last 12 months. Yet, with another potential growth catalyst on the horizon, could this be just the tip of the iceberg?
Last month, persistent US inflation prompted the Federal Reserve to raise interest rates for the first time in three years. Here in the UK, the Bank of England held rates steady at 3.75%.
But consensus is rising that a similar-style rate hike could emerge before the end of the year. And for a bank like Lloyds, that’s great news for its lending margins.
So, does that make this bank stock a potentially top-notch investment today? And could we be looking at the start of another doubling for Lloyds shares before the end of 2027? Let’s take a closer look.
A delicate balancing act
Higher interest rates can be terrific for banks. After all, it allows the gap between the interest it pays to its depositors and the interest it charges to borrowers to widen. And with largely fixed operating costs, that can open the door to enviable operating leverage, boosting both profits and net interest margins in one stroke.
The impact of this tailwind is already visible.
Looking at the results from the first half of 2026, net interest income rose 9% to £7.3bn, while the banking net interest margin expanded from 3.04% to 3.19%.
The result? A 23% surge in pre-tax profits reaching £4.3bn.
Subsequently, management now expects 2026 net interest income to exceed £14.9bn by the end of the year. And with its underlying loan book also rising by £10.4bn to £491.5bn, the bank is not only earning more profit from its existing loans but successfully issuing new ones as well, even though interest rates remain elevated.
So, what’s the catch?
Higher rates can be a powerful boon to banks like Lloyds. But they can also backfire. As mortgages, car loans and credit cards become expensive, demand and affordability suffer, resulting in both lower volumes and higher defaults.
In fact, we’re already starting to see the impact of increased financial pressure on some of Lloyds’ customers. Impairment charges across the first half of 2026 jumped 39.4% from £442m to £616m.
Compared to a nearly £500bn loan book, this is far from disastrous. But if impairments continue to rise and loan book growth starts to stagnate, then there could be more cause for concern – a key risk to watch closely moving forward.
Can it double?
For the Lloyds share price to double by the end of 2027, it would need to reach roughly 218p and a market cap of £125.8bn.
Over the long run with continued solid execution and prudent leadership, Lloyds could eventually reach this threshold. But expecting such enormous growth in the space of the next 15 months seems quite unrealistic. At least, not without a major earnings catalyst.
So, personally, I think investors expecting this bank stock to double before the end of 2027 will likely be left disappointed. But for those looking for a quality long-term holding in the UK banking sector, there’s still plenty to like here. And it’s not the only promising potential opportunity on my radar right now…
